    Fifty-four mandibular prognathism patients seeking surgical correction underwent psychological evaluation using MMPI before the operation.
    The results are as follows:
    1. There was no personality deviation which commonly characterized the personality of a mandibular prognathism patient.
    2. Eighteen (33%) of the subjects exhibited some deviation of personality demonstrated by high T scores (more than 65) on several clinical scales of MMPI.
    3. The relationship between the degree of facial deformity measured with the quantity of over-jet and the T scores of MMPI scales was evaluated. The results showed that the minimal deformity group and the largest deformity group were inclined to have high T scores on several clinical scales of MMPI. The results also indicated that there was no correlation between the degree of deformity and the deviation of personality.
    4. The greater the ratio of the degree of suffering from the facial deformity to the degree of over-jet, the greater was the occurrence of patients with remarkable deviation of the personality. It was also shown through multiple regression analysis that the Sc scale had large positive weight in the prediction of the ratio taking into consideration the standard partial regression coefficients (STB) of each scale.
    5. In fourty-five subjects, there were twelve cases of patients who exhibited problematic behaviour during the course of treatment of their deformity. They tended to be suffering a great deal psychologically although their facial deformity was less than average. The multiple regression analysis showed that the Pd scale, the D scale and the K score of MMPI were very accurate in predicting problem patients. The higher the score of the Pd scale and the D scale, the more troublesome the patient was. On the other hand, the higher the score of the K score, the less troublesome the patient.
    6. The frequency of the occurence of problem patients was higher in male patients than female patients. A great deal of attention should be paid to the psychological aspect of male patients in the surgical treatment of mandibular prognathism.

    Little is known about the pathogenesis of cleft lip, compared with that of cleft palate, because normal developmental processes of the primary palate have not been thoroughly clarified. In this study, scanning electron microscopy was carried out on epithelial cells of the primary palates and mesenchymal cells just underlying the epithelia both in normal and abnormal (cleft lip) embryos in the 9.5-13.5 th gestation days. The latter was induced with i. p. injection of hydantoin to A/J mice. The following results were obtained.
    1) The epithelial changes in the normal primary palate formation, were the same as those reported previosly during the secondary palate morphogenesis, but not in cleft lip malformation. These changes in normal animals appear to be associated with the fusion of the medial and lateral nasal processes.
    2) Three types of epithelial cells (periderms) were recognized during the primary palate formation. Because these three types of cells might specifically appear according to differentiation of each part of the embryos, this classification may represent some information on inner developmental changes.
    3) In hydantoin-treated embryos, both posterior ends of medial and lateral nasal processes did not fuse, and thus mutually separated to cause partial or complete cleft lips according to degree of the breakdown of the isthmus. The main cause of these failures seems to be related to abnormalities in mesenchymal cells adjacent to the surface epithelium.

    In 60 cleft palate patients who received a pharyngeal flap operation, the growth of articulatory organs and maxilla were measured using a latelal cephalometric x-ray taken before and after the operation. The rates of expiratory leakage through the nasal cavity were also measured to comparatively study the effects of a pharyngeal flap on nasopharyngeal function and on the growth of maxilla, in terms of age at the time of operation, type of clefts, and structure of pharyngeal flaps.
    1. The inclination of soft palates tended to decrease immediately after the operation. This was especially remarkable in younger patients.
    2. The fore and rear diameters of the pharynx started to reduce immediately after the operation, and became constant after 1 year. The time-dependent change after the operation was not significant.
    3. The diameter of soft palates increased by 3-7 mm after the operation. Abortive soft palates were greatly related to the incomplete nasopharyngeal function.
    4. The expiratory leakage through the nasal cavity was remarkably improved in the younger patients. In the case of the patients of 16 and up, no improvement was observed even after the operation.
    5. The growth of maxilla tended to be suppressed after the operation in the younger patients.
    6. As a result of comprehensive consideration of the nasopharyngeal function and the growth of the maxilla, it has been concluded that the optimum age for the pharyngeal flap operation may be 6 or 7 years old.

    Several treatments have been chosen as methods of surgical technic of the dentofacial deformities depending on various conditions.
    The results of the treatment are highly influenced by pre-operative planning. Then it is necessary to make a perfect pre-operative planning by understanding data of the dentoskeletal analysis. In order to get enough information from the facial profile, a comprehensive cephalometric analysis of “normal” adults was accomplished by examining a carefully selected subject group (30 men and 30 women) between the ages of 18 and 22.
    The X axis as a standard axis is constructed by drawing a line through nasion 6° up from sella (s)-nasion (n) line and the Y axis is a straight line crossing the X axis and passing point N. The 43 examining points (26 points found on the soft tissue and 17 points found on the hard tissue) were created on this X and Y axis. The 26 soft tissue points were considered as a function of several hard tissue points. Soft tissue-to-hard tissue ratios after operation were made by examining the 70 patients (with an average post-operative follow-up of 6 months) who required orthognathic surgery. A standardized profile was created from these data.
    The computer system was introduced based on this standardized figure and data This system is very useful for diagnosis, treatment planning and prediction of post-operative soft-tissue profile.

    Small defects were produced in the dog's mandible by CO2 laser, and surface deposit of carbonized and heat-coagulated tissue elements were debrided. The tissue response was examined histologically immediately, at 2, 4, 8 and 16 weeks following the surgical procedure. Healing was compared with defects produced by a diamond bur, and also with defects lased and not debrided. The debrided defects demonstrated an almost similar rate of healing compared with the defects produced by a diamond bur, which showed more favorable healing compared with the lased and non-treated defects. Dog's canine was also irradiated by CO2 laser, and the alteration of temperature in pulp cavity was measured in vivo. The tissue response was also examined histologically immediately, at 1, 2 and 4 weeks after irradiation. Temperature rose to 44°C (20W 3 sec) and to 51°C (40W 3 sec) in the center of the pulp. Histological findings of the pulp sugested that the threshold temperature of pulpal damage caused by heat existed between 44°C-51°C. Healing of the pulp was almost favoable, and reparative dentin was observed after 4 weeks.

    This paper presented the new device of external pin fixation method and appraisal of its clinical use. This new apparatus consisted of three parts of two different types of pin system, namely, HH (the initial of Hajime Hayashi) type pin system, HY (the initial of Hiroyuki Yamanaka) type pin system and the kirschner wire (diameter 3.0 mm). This combined fixation system was developed based on rigidity of pin, flexibility of klemme and easy adaptation of length of wire rod.
    It was applied to six cases of iliac bone grafting and five cases of maxillo-facial bone fracture, to which it may have been thought that ordinary fixation were not enough to get the stability of grafted or fractured bone. This worked very well in all cases, except in one case of iliac bone grafting because of its poor bed condition.
    Thus, clinical results showed this new type of external fixation system (we call it “Mei-dai system”) was much more useful and easier to get rigid fixation than other pin systems (ex. HH type alone, HY type alone, Roger-Anderson type etc.).

    Recent years, the number of patients with long-term hemodialysis are rapidly increasing. These patients may develop secondary hyperparathyroidism with oral symptoms and have many complications caused by abnormal change in bone, cardiovascular and immunological dysfunction, etc.
    The problems of many complications and surgical procedure were discussed.
    Case 1. A 25-year-old man with 8-year history of hemodialysis therapy was admitted to our hospital on Aug. 24. 1982 because of masticatory disturbance. He had remarkable bone change involving the whole skeleton, especially tumrous enlargement of the palatal bone. AL-P and PTH level were 91.2 K.A.U. and 73.7 ng/ml, respectively. The tumorous enlargement of the palatal bone was resected partially under general anesthesia.
    Case 2. A 33-year-old woman with 11-year history of hemodialysis therapy as admitted to our hospital on Feb. 15. 1984 because of masticatory disturbance and aesthetic dissatisfaction. She had remarkable bone change involving the skeleton, especially tumorous enlargmement of the maxilla. AL-P and PTH level were 273. 4 K.A.U. and 20.2 ng/ml, respectively. The tumorous enlargment of the maxilla was resected partially under general anesthesia.

    Combination chemotherapy was effectively used after the surgical operation of a case of 30-year-old female with osteosarcoma arising in a fibrous dysplasia of the left mandible. In this case, a high dose methotrexate (MTX 12g/“cours”) with citrovorum (CF) rescue was administered mainly by six “cours”, in combination with several chemotherapeutics, such as Adriamycin (50-70 mg), Endoxan (EX 800-1, 000 mg) Vincristine (VCR 2.5 mg), resulting in total dose of 72 g, 490 mg, 6, 900 mg and 19 mg, respectively. This therapy has probably been very effective, because a possibility of recurrence was strongly considered from the viewpoints of a relapse after the first operation and the clinical findings during the second surgery.
    Side effects of the chemotherapy were relatively mild and temporary.
    No relapse has been observed in the last two years after the treatment.
    It was proved that this chemotherapy was applicable with safety and very effective for the treatment of osteosarcoma provided that the cases are chosen and put under supportive medical care.
    In this paper, an administration method of such chemotherapeutics is described.

    Clinical observation was conducted on 208 fracture lines in 138 patients with fractures of the mandibula alone (except the fracture of the alveolar process) in which the situation at the time of infliction of the trauma and fracture lines was clearly established, to evaluate the mode of occurrence in fracture of the mandibula.
    The cause of trauma consisted most frequently from accidents on motor cycles, followed by a fall and beating, therefore the intensity of the external force has been thought to be of medium degree in most of the cases.
    In the cases, that had 2 or 3 fracture lines, the following tendences were evident. Infliction of external force on the midline portion was apt to cause a direct fracture of the midline portion and indirect fracture of the mandibular process. Infliction of external force on the mandibular angle frequently caused a direct fracture of a mandibular angle and indirect fracture of the anterior portion of the mandibula.
    As to the relationship between the site of the infliction of external power and site of the fracture in the cause of mandibular process fracture, the shift of the site of impact from the lateral mental region, mandibular body and mandibular angle resulted in an increase in the number of the fracture lines in the contralateral side.
    The mode of fracture in patients with an unstable condition of the mandible at the time of infliction of the trauma was in keeping with the results of experimental studies conducted on the fixation of the mandibular process that has already been reported. Therefore the weak portion of the mandibula appears to be reflected more simply in the case of the unstable mandible.

    Nodular fasciitis is a benign pseudosarcomatous proliferative lesion of the soft tissue, found in the subcutaneous fascia, usually of the upper extremity or trunk. It is frequently found to be a rapidly growing mass, and so it should be cautioned not to misdiagnose to be a malignant neoplasm.
    Accumlation of a large series of nodular fasciitis in the orofacial region indicates that this anatomic site is perphaps uncommonly but certainly not rarely affected. This report deals with the detailed description of a case of nodular fasciitis in the mandible and made a review of the literatures.
    The patient, a 3-year-old girl reffered to the clinic with the chief complaint of a tumor mass in the left inferior border of mandible.
    The rentgenologic examination revealed a periosteal reaction at the cortical bone adjacent to the tumorous lesion. A consequence of the histopathological study on the biopsy material showed nodular fasciitis.
    Follow-up information is favorable and proves the benign nature of the lesion. Differential diagnosis in relation to the other benign and malignant tumors in the region is also discussed.

    Odontoma composed of dental hard tissues, is a typical odontogenic tumor, which is divided into two types. Generally, the odontomaenlarges up to wal nut size, therefore finding a tumor of this type large enough to require dissection of the jaw is rare.
    On the other hand, simple bone cysts termed haemorrhage bone cysts or traumatic bone cysts, occur most often in the humerous and other long bones. They are not often in the jaws.
    This paper reports a case where the odontoma and simple bone cyst occurred simultaneously in the same region of the mandible. The patient, a 16-year-old boy, complained of malocclusion on 7 of his gingiva and was refered to this hospital. Roentogenographic examinations revealed the radiopaque region which seemed to contain odontoma in the mandibular body and also showed mutiocular cyst-like radiolucent area in almost all of the ramus which was suspected to be an ameloblastoma.
    Mandibular dissection was done from 6 and reconstruction of the jaw was performed using the intact cortex including the condyle after the tumor as enucleated. The histopathological diagnosis was compound odontoma and simple bone cyst.
    The patient was observed periodically and the prognosis was good for eight months after the operation.

    Verrucous carcinoma was first described by Ackerman in 1948, and is generally referred to as “Ackerman tumor”. In Japan, a case was reported in 1967 by Kozaki et al, followed by a report by Ishikawa et al, in 1970. This tumor is regarded clinically and histopathologically as a squamous cell carcinoma with relatively benign characteristics. It is relatively rare and found in the oral cavity region.
    The authors reported a case of verrucous carcinoma in a 73 year old male. The patient felt irritation in his lower anterior alveolar region with his tongue, one month prior to visiting the Oral Surgery Dept. on October 23, 1980. Due to the lack of subjective symptoms, he failed to apply for a medical examination. At his first visit, his chief complaint as a slight increase in tumor. The case was examined at our clinic at the Department of Oral Surgery, School of Dentistry Higashi Nippon Gakuen University.
    Upon examination, the tumor was found to be a peduncular the last part of this sentence is not clear tumor with a relatively soft and wide base. It extended over the lower anterior alveolar crest region from 3 to 4 mediodistal region. It reached the mucolabial fold on the lip side and touched the mouth floor mucosa on the tongue side with a surface that resembled califlower. The tumor was suspected to be a gum papilloma or possible carcinoma and was extirpated. After extirpation of the left glandula submandibularis and the gum and alveolar process from 3 distal region to 4 distal region in a lump, ilium transplantation into the region was conducted. Four years and 8 months after the operation the recovery course may be considered favorable.
    Pathohistologically, the tumor was a papillary proliferation of stratified epithelium accom panied by slender connective tissues. Rather than penetrating deeply into the lamina propria, it appeared as a papillary proliferation of the epithelium in a downward direction. The point of the leading portion of the proliferation base was higher than the line drawn between the ends of the circumferential mucous menbrane. At the same time, a somewhat deep and narrow cleft was seen between the papillary epithelia, but no substance filling the cleft was seen. Histologically, the tumor comprised mainy of acanthosis with a slight degree of parakeratosis. In the basal layer atypia of epithelial tumor cells to a slight degree was seen. On the other hand the basement membrane was preserved but phlogocyte infiltration was intensive and destroyed the basement in places. Thus, the tumor was determined to be verrucous carcinoma from the histopathological diagnosis.

    In this paper a 79 year old man of secondary invasive carcinoma arising from erythroplakia of soft palate was reported.
    He was admitted to Tohoku University Hospital of Dentistry on November 11, 1981.
    He had not been aware of the erythroplakia untill was indicated by a dentist a week before admission.
    He had suffered from pulmonary tuberculosis 7 years ago.
    Routine laboratory examinations were within normal limits.
    Radiographic examination revealed a thumb tip-sized modular calcification as tuberculous focus in the pulmonary hilar region of right lung.
    The regional lymph nodes were normal in size and consistency. Inspection of the oral cavity showed two erythemas in the right soft palate. One was 20×10 mm in size, flat, red velvety, and sharply circumscribed. Another was 20×15 mm in size, slightly elevated, granular, red, slightly indulated and well demarkated. The former was clinically diagnosed homogeneous erythroplakia, the latter granular erythroplakia.
    Both erythemas were clearly stained dark blue by application of toluidine blue to the soft palate.
    Microscopic examination of a biopsy specimen of homogeneous erythroplakia showed carcinoma in situ and granular erythroplakia invasive carcinoma (squamous cell carcinoma).
    He was treated by irradiation (Linac X-ray, 60 gy.) and chemotherapy (Mifurol, 12.8 g). Therefore these erythermas remarkably disappeared, and histological examination showed no atypical epithelium and carcinoma. 3 years and 5 months postirradiatedly there are no recurrences or detectable metastases.

    Presently, there is general agreement that, while odontogenic keratocyst may be of varied origin, one clinical feature warrants its recognition and separation as a distinctive entity: the exceedingly high recurrence rate.
    We reported a case of odontogenic keratocyst extending from the second molar to the ramus of the right mandible with an impacted tooth in the mandibular condyle region.
    The patient, a 20-year-old woman, visited our hospital to examine the ramus of the right mandible.
    In radiological findings, from the 7 position to the ramus of mandible, a unilocular shadow with a scalloped periphery was observed.
    We operated on the mandibular resection from the 7 position to the ramus of mandible of the right side with mandibular condyle. Then we performed an immediate reconstructive operation of the mandible by autogeneus illiac bone grafting.
    The lingual cortical plate of the ramus of mandible was perforated.
    In histological findings, the lining epithelium of cyst wall was stratified squamous with parakeratosis. Epithelium was consisting of 6 or 8 ros of the cells, and showed dental laminalike epithelium.
    There is the cyst wall between the impacted tooth in the mandibular condyle region and the lumen of this cyst. The lumen of this cyst was filled with a thicker creamy material.
    Two years have passed since the operation and the prognosis is favorable without recurrence.

    The Lipoma is one of the most common and most widely disseminated mesenchymal tumors found in the human body, but is rarely found in the oral regions.
    In this paper, a 44-year-old woman with lipoma in the right lower lip was reported, and 157 cases of lipoma in the oral regions that have been reported in Japan were discussed.
    The patient visited the Tohoku University Hospital of Dentistry with the chief complaint of a tumor in the right lower lip.
    No abnormalities were observed in the patients past or family history.
    She first noticed a rice grain sized tumor in the lower lip about five years ago, and the tumor gradually increased in size thereafter.
    Oral examination revealed that the tumor was well circumscribed, thumb tip-sized, elastic soft in consistency and yellowish red in colour.
    The tumor was clinically diagnosed lipoma and resected under local anesthesia.
    The specimen was a spherical, encapsulated, soft, yellowish mass measuring 22×17×12mm.
    Microscopically, the tumor consisted of matured adipose tissue, therefore histopathological diagnosis of the tumor was simple lipoma.
    1 year postoperatively there is no sign of recurrence.

    Cleft lip and palate is the most common abnomalities among congenital facial malformation. However, it is very rare that both twins have cleft lip and palate.
    Zygosity diagnosis is very important for the investigation of the etiology of this malformation. In twins with cleft lip and palate reported here, zygosity diagnosis was done by the similarity method, blood type and HLA halotype. From these results, we concluded that they were monozygotic.

    The mandibular reconstruction by using Dacron-Urethane prosthesis, costchondral graft, fresh autogenous marrow & cancellous bone chips and kirschner's wire was performed on the 20-year-old female whose left hemimandible was diagnosed as central hemangioma and was resected at of 8-years of age. The satisfactory results were obtained from both esthetic and functional aspects.
    The operative procedure by using Dacron-Urethane prosthesis after Schwartz has many advantages not seen in other procedures. We suggest that this procedure should be employed in such cases as the large defect of the mandible or defected parts of the mandible are hard to be reconstructed.

    Ameloblastoma is a common tumor in oral and maxillofacial regions. It is also found in children from birth to 9 years of age, although it usually occurs in the second and third decades of life.
    Recently we have experienced two cases of ameloblastoma arising in the mandible of a 9 year-old female, and a 4 year-old male.
    Radiological examinations showed multilocular lesion of the mandible in the first case.
    On the other hand monolocular defect of the mandible was found in the second case.
    The enucleation of the tumor and surrounding medullary bone was performed in both cases.
    Light microscopic findings revealed the typical features of ameloblastoma in both cases.
    Postoperatively, there was no evidence of recurrence, facial contour was nearly normal, and mandibular function was nomal.

    The basal cell nevus syndrome is inherited as an autosomal dominant trait with probably high penetrance and variable expressivity. The syndrome is characterized by cutaneous lesions such as multiple basal cell nevi and basal cell epitheliomas as well as palmar and plantar pits, multiple jaw cysts, skeletal anomalies, additional anomalies of facial skull and ectopic calcifications including those in intracranial areas.
    In this paper, a mother and her daughter are described with manifestations of the syndrome in a Japanese family. Many malformations associated with the patients are presented, who have something in common with each other in their appearance of symptoms, involving multiple jaw cysts, temporofrontal bossing (increased intracranial circumference), broad nasal root, intracranial calcifications, scoliosis, whereas skin lesions, including palmar and plantar pits, bifid rib, ocular hypertelorism, and dilatation of the ventricle are seen in one-side of the patients. These results confirm previous findings that the syndrome exhibits variable expressivity in the mother and her daughter as well, hence a certain kind of factor other than genetic background possibly plays an important role in variable expressivity of the syndrome.
    There are many subtle malformations inherent in the syndrome, as mentioned above, while the CT scan shows distinctly a peculiar and possibly common feature to the syndrome, which involves intracranial calcifications in the falx, tentorium and diaphragma sellae, suggesting that the CT scan proves to be of great use to establish the diagnosis of the syndrome.
    A simple pleitropic gene or multiple closely linked genes may participate in multiple malformations involving organs and systems of both ectodermal and mesodermal origin, as suggested before by Gorin and Goltz. The possibility of their suggestion is described and reevaluated. On referring to decreased DNA repair synthesis in the syndrome described already by several workers, the etiology of the syndrome is also discussed.

    The analgesic effect of 156-S on postoperative pain after removal of impacted lower wisdom teeth was clinically elvaluated. After the appropriate dose of 156-S was preliminarily studied among 50 mg, 100 mg, 200 mg, 300 mg, and 400 mg groups, 300 mg of 156-S was compared with 500 mg of mefenamic acid by the double blind test.
    The result were as follows:
    1) Of the total 520 cases, 408 cases (78. 5%) needed analgesics after the extraction.
    2) The analgesic effect of 156-S increased dosedependently among 50 mg, 100 mg, and 200 mg groups in the first preliminary test.
    3) 200 mg, 300 mg, and 400 mg of 156-S were clinically effective and useful to control the postoperative pain in the second preliminary test.
    4) Although both 300 mg of 156-S and 500 mg of mefenamic acid showed the almost same analgesic effect clinically, postoperative pain was statistically better controlled by 156-S than by mefenamic acid at 30 and 60 minutes after administration of the analgesics.
    However, the analgesic effect of mefenamic acid is statistically superior to that of 156-S at 4 hours after the administration. These results suggest that 156-S has quick analgesic action and mefenamic acid has a long one.
    5) Side effects of 156-S slight gastrointestinal disorder, were found in only 6 of 322 cases (1.8%).
    6) Therefore, 156-S is good for controlling the postoperative pain after extraction of impacted lower wisdom teeth.
