    A case of hemorrhagic bone cyst experienced in our oral surgery is reported. At first the case was diagnosed by X-ray and cyst fluid inspection. Then we analyzed the components of cyst fluid. When a cyst is infected, white blood cells and the free radical level in cyst fluid increases, and PO2 level decreased. Conversely when a cyst is not infected, white blood cells and the free radical level decreases, and PO2 level increases.

    We studied a mucosal cyst in the maxillary sinus with X-ray, CT-scan, and histopathological observation. Further, we analyzed the cyst fluid by IR and HPLC.
    1) The cyst was semicircular dome-shaped on the floor of left maxillary sinus. We thought CT-scan is the most effective method for diagnosis of this cyst.
    2) There is a possibility that the mucinoid component of cyst fluid is hyaluronic acid.

    We observed capsules of impacted teeth and follicular cyst walls with light microscope and electromicroscope. Further we compared the components of capsules with cyst walls by IR which lead to the conclusion that they are similar in morphological observation and components. Therefore there is a possibility that impacted teeth having capsules include the first stage of follicular cyst.
    When impacted teeth have capsules, we can diagnose correctly using X-ray and histomorphological observation better than solely by X-ray.

    From 1976 to 1984, 547 cases with mandibular fractures were treated in the Department of Oral Surgery, Sapporo Medical College Hospital. These were analysed clinicostatistically and the following results were obtained:
    1) During this period, the number of cases increased and the most patients came during the summer months which correspon well with other departments of oral surgery.
    2) Age of patients distributed widely with peak of second and third decades (56.5%). Remarkably more (76.6%) male patients than female.
    3) The traffic accident cases were very frequent (42.2%), falls in 15.5%, work accidents in 11.9%, athletic injuries in 11.7% and others in 2.4%.
    4) The majority of mandibular fracture lines were found in so-called “weak” areas of the mandibule, i. e., the region of condyle (25.0%), incisor (18.0%) and mandibular angle (15.8%).
    5) Regarding the therapy, 380 cases were treated by closed reduction (69.5%), 139 were treated by open reduction and 28 were by alveolarplasty. Recently, the A. O. dynamic compression plate was used in many types of mandibular fractures.

    Clinical and radiographic examinations were made of 60 children with jaw fractures which we treated in the past 17 years. Follow-up examinations were made of 33 of these 60 patients. The results obtained are as follows:
    Clinico-roentgenographically,
    1) Traffic accidents were the chief cause of jaw fractures.
    2) Of these 60 children, there were about 3 times as many boys as girls.
    3) Five to six-year-old children experienced jaw fractures most frequently.
    4) Some changes were observed in likely sites of fracture by age-groups, however, so far as the condylar fracture is concerned, all age-groups experienced such fracture frequently.
    5) From the therapeutic viewpoint, many of fractures in the horizontalramus were treated by the conservative technique, and all of the cases with only fracture of the mandibular condyle were so treated.
    From the viewpoint of follow-up examinations,
    1) Root malformations were observed in 6 of 28 permanent teeth germs present on the line of fracture just suffered.
    2) Of these 6 teeth germs, 4 were cases where open reduction was performed at the same sites. In all cases, malformation occurred on simple rooted teeth, and 5 teeth were found unfinished in preparation of crown.
    3) Morphological abnormality of the mandibular condyle was observed in 3 of 13 fracture of mandibular condyle cases.
    4) However, no jaw underdevelopment and/or joint dysfunctions were observed.

    Clinical reports were made on five cases that arose in the maxilla within 104 cases of the ameloblastoma which were diagnosed in the First Department of Oral and Maxillofacial Surgery of Osaka Dental University during 16 years from 1968 to 1983. Age of the patients ranged from 30 to 79 years old. Mean age was 53.4 years and significantly higher than the mean age of the ameloblastoma in the mandible (32.3 years old). Three cases were male and two were female. Two cases involved maxillary tuberosity and a case in anterior region. Two cases included the border between the anterior and molar region. Histologically, tumors showed the atypical form of ameloblastoma like acanthomatous metaplasia. Stroma was the dense fibrous tissue. Radiographic examination disclosed varied appearance types (three unilocular, one multilocular, and one soap bubble-like). Concerning three operated cases, two cases of partial maxillary resection had good clinical courses but a case of enucleation of the tumor recurred two years later.

    Reconstruction using various pedicled flaps for oromaxillofacial defects makes a patient's return to social life easier and contributes to the improvement in therapeutic results especially in malignant tumors. In the past 6 years from 1978 to 1984, a review of 35 patients where these flaps were used is as follows:
    1) Deltopectoral flaps with or without the transplanted bone for secondary reconstraction of 10 cheeks and 2 mandibular defects required long terms because of the delay transferring the baps, but there was less operative invasion.
    2) Major pectoralis myocutaneous flaps for 14 immediate reconstructions of the tongue, floor of mouth, oropharynx and mandible were effective in the repair of soft tissue defect, but not always successful in reconstruction using osteomyocutaneous flaps with the rib or sternum for mandibular defects.
    3) In the 2 adult males, the scalp-forehead flaps for immediate reconstruction of the entire upper lip were cosmetically used to make a mustache using the hair-bearing scalp.
    4) Flaps of 2 sternocleidomastoids and 5 cervical island skins for immediate reconstruction of the moderate defect in the tongue, floor of mouth and alveolus were taken at the time of neck dissection. However, some flaps caused a postoperative necrosis because of excessive tention due to suturing of the wound and insufficient blood supply, different in previous other flaps.
    Reconstruction using the above-mentioned flaps was indicated in large and moderate defects. Survival rate of patients with tumor resection from one to five years was as follows; 81.1% in 11 deltopectoral flaps, 57.1% in 14 pectoralis major myocutaneous flaps and 100% in 9 other flaps.

    A rare case of benign osteoblastoma with multiple cystic lesions of the mandible is presented.
    A 58-year-old man came to our department with. chief complaint of swelling of the right part of the mandible for approxiamately 2 years.
    A radiograph showed an opaque, well defined, and measuring 5.0×6.0cm osteoblastoma in the second morlar part of the mandibular osseous body with widespread multiple cystic lesions. Rapidly increasing of swelling indicated malignancy, so surgery with hemimandibulectomy was carried out.
    The histologic features of the entire specimen proved its benign character and it was diagnosed as a benign osteoblastoma. The patient is doing well 5 years after surgical treatment.

    In our country, ameloblastoma is a typical tumor occurring in the oral cavity. The lower jaw is the usual site and upper jaw incidence is relatively low.
    A follicular dental cyst-like lesion in right maxillary sinus was recently experienced. Extirpation of the lesion site, sinuectomy and ethmoidectomy were performed based on Caldwell-Luc's radical operation.
    Postoperative histopathological examination showed that the excised cyst-like lesion contained a plexiform type ameloblastoma. The final diagnosis of a mural ameloblastoma was established by operative finding and histopathological examination. Since the mural ameloblastoma of the maxilla is very rare in existing literature, it is presented in this paper.

    A case of adenoid cystic carcinoma which appeared in the floor of the mouth, is presented.
    A 75-year-old man visited to our hospital with a chief complaint of a painless tumor in the floor of the mouth. The patient was treated with surgical resection and received a course of postoperative radiation therapy (39 Gray).
    Microscopically, the resected material consisted mainly of typical cribriform structure. Electron microscopic observation revealed that the tumor cells were able to divided into the following two cell types; light cell (secretory-like cell) contained a small amount of secretory granules and dark cell (tumoral myoepithelium) without filament structures. Ultrastructural findings suggest that the tumor cells are poorly differentiated.
    Postoperatively, the patient made an uneventful recovery and the wound healed satisfactory. There had been no evidence of recurrence, nor any metastasis of this tumor until the last regular observation.

    Combination of hydroxyapatite granules with fibrin adhesive provides a useful new technique for augmenting bone defects after minor oral surgery. During our clinical experience in augmentation with hydroxyapatite granules alone, the material too easily dispersed which made it difficult to use. In this respect, hydroxyapatite granules and bobrin adhesive compounds are much easier to use. Fibrin adhesive produces the initial stabilisation of the hydroxyapatite granules, making it possible to reconstruct the bone defect.
    We used this procedure in 10 cases of minor oral surgery involving 4 cases of radicular cysts, 1 case of radicular granuloma, and 5 cases of chronic marginal periodontitis. Successful augmentation occured in 8 cases.

    Secondary mandibular reconstructions using osteocutaneous flaps were performed in a 27-and a 64-year-old male patients, who had a mandibular defect with contructure of scar in the surrounding tissue. Primarily, in the first case, an iliac graft and in the second case, a 7th rib graft were wrapped when making a deltopectoral flap, respectively. Secondarily, each osteocutaneous flap was transplanted to the defect for reconstruction of the mandible following deepithelization. In the iliac graft, the mandibular reconstruction was successful, and in the rib graft, it resulted in a pseudoarthrosis due to postoperative infetion and salivary fistula from injury to the parotis gland during operation.
    The previous two experiences suggest to us the following: 1) Bone graft wrapped in the deltopectoral flap may maintain blood supply and tolerate postoperative infection. 2) The union between the cutaneous flap and bone graft was stronger in the iliac graft than in the rib one. Because the surface of the rib is flat and covered by the cortical bone, morphologically, its combination force is inferior. 3) This technique is disadvantageous, because it takes much time owing to delays, but it has an advantage of minor damage by operation. 4) For the purpose of fixation of the graft and the mandibular stump, utilization of metal plates or intermaxillary fixation in a term should be performed.

    Cleidocranial dysostosis is a congenital angmaly with clavicle and cranial osteogenesis imperfecta accompanied by abnormality of dental eruption.
    This disease was first reported in 1765 by Martin and named cleidodranial dysostosis in 1897 by Sainton and Marie.
    In our country it was documented first by Takahashi in 1925. It is a relatively rare disease not only in Japan but also in occidental countries.
    Recently we encountered 21-year-old male patient with absence of bilateral clavicle and zygomatic arch fontanel opening, separation of public symphysis, prolonged retention of deciduous teeth, and 23 impacted teeth.
    Treatment consisted first of extraction of deciduous teeth and then of fenestration in the regions of the left and right canines and first premolars of the mandible. Resin buttons were attached to these teeth for traction with rubber bands. The patient is at present in a careful follow-up study.

    There are few systemic examinations of oncocyte in normal salivary glands, so the genesis of oncocyte remains obscure.
    In this study, we examined the appearance and histological patterns of oncocyte in 436 cases of human labial salivary glands obtained from patients of various ages. We discussed the possible mode of development and the significance of these cells. The results were as follows:
    1) Oncocytes were found in 20 persons (4. 6%) ranging from 11 to 77 years of age and were more often observed in the over 50-year-olds. The frequency was slightly higher in females than in males.
    2) Oncocytes were noted in the canalicular system interlobular ducts, large intralobular ducts and small intralobular ducts but were not found in acini and excretory ducts.
    3) Multiplicated patterns, such as infolding or stratifying of oncocytes in the duct wall were more frequently found in older cases.
    4) In 12 of 20 oncocyte-positive cases, the oncocytes were observed in areas of the probable proliferation including the various patterns, that is, stratification, cyst formation, papillary projection and the group such as microtubular appearance, and such appearances were found more frequently in older cases.
    5) The relationship between the presence of the oncocyte and the glandular inflammatory change was suspected. In 12 of 20 oncocyte-positive cases (60%), inflammatory changes of labial salivery glands were recognized.
    6) Development and presence of the oncocyte may be influenced by systemic factors such as Sjögren's syndrome, because of the fact that oncocytes were recognized in 11 cases of Sjögren's syndrome.

    Etretinate, retinoic acid analog, was administered to oral squamous cell carcinoma (16 cases) with combination chemotherapy; bleomycin or pepleomycin, radiation and radical operation. Clinically, neoplastic masses disappeared or tumor growth markedly inhibited with Etretinate therapy as compared to conventional chemotherapy. Tumors in six cases almost disappeared and did not grow in nine cases.
    The effects of Etretinate administration were characterized by the existense of necrotic defects starting from tumor surfaces. Histopathologic features in the tumor tissues administered with Etretinate showed an intene vacuolization and extending intercellular spaces in treated tumor cells. Etretinate administration was more effective in the well keratinized type of the squamous cell carcinoma, and it was recognized wide variations to anti-tumor functions and side effects. Dermatological disorders, itchness and epidermis abrasion were usual side effects and were improved by stopping administration. Combination chemotherapy with Etretinate was useful to reduce or inhibite tumor growth in oral squamous cell carcinoma.

    A case of metastatic mental epidermoid carcinoma from the primary esophageal lesion which occurred in a 51-year-old man was reported and the Japanese literature on the metastatic tumor to the mouth and jaws was reviewed from 1940 to 1983.
    Only two metastatic cases to the mouth and jaws from the esophageal malignant tumors have been counted until now, namely 57 metastatic tumors to the mouth and jaws were documented in the almost equal occurrence of sex with a range of 1 to 76 years old as far as examined. The commonest primary organ was the uterus with the following order in incidence of the lung, kidney and stomach. Histologically, the carcinoma of the grandular origin showed the highest rate (about 49%), while the squamous cell carcinoma and sarcoma were unutual. Metastasis occurred on the gingiva in 29 of 57 cases. Concerning osseous metastasis, the mandible was the most frequently involved site, and the usual symptoms were swelling, tumor formation, bleeding and pain.

    One hundred and nine patients aged 21 to 76 with rheumatoid arthritis were investigated for the incidence of the temporomandibular joint (TMJ) involvement clinically and radiographic changes. Sixty-eight (62.4%) out of 109 patients had experienced TMJ symptoms at some time during course of their disease. This figure agrees nearly with other recent studies.
    The range of opening mouth in patients with TMJ involvement was not reduced significantly compared to that in patients without TMJ involvement.
    The high incidence of TMJ involvement seemed to be related to the positive RA factor, early onset of RA, long disease duration and acute polyarticular type of RA. Joint noise (crepitus), pain and limitation of jaw movement were the main clinical symptoms. It is likely that the progressive anterior open bite and chin posterior positioned were characteristic features of TMJ with RA.
    Radiographically, the surface erosion and flattening of TMJ condyle were frequently observed. No evidence of bony ankylosis in TMJ were found.
    In the severe case, the condyle was erode out and under subluxation.
    The longer disease duration, the severer radiographic changes were found.

    1) Blood flow for the nylon suture group showed a recovering tendency just postoperatively, and 5 days later, returned to its quasi-normal range with a significant difference from the Tisseel® adhesion group.
    2) Blood flow for the Tisseel® adhesion group showed only half of that for the nylon suture group on the first postoperative day, and then gradually increased to reach that for the latter group on the 6th postoperative day.
    3) Histopathological searches revealed that the former group showed a wound healing process a little more retarded than the latter group till the 5th postoperative day.
    The above results suggest that the present LDF-blood flowmetry constitutes one of the hopeful means for various kinds of researches in future in that together with its consistency with related histopathological findings, it well reflects the peripheral blood flow kinetics and permits sensitive measurements of the tissue blood flow with delicate variability.

    A case is reported of lipoma presenting as a lesion with clinically interesting attitude in a 49-year-old man.
    The tumor arose near the region of the facial artery corresponding to the right mandibular body and revealed a pseudofluctuation on palpation. Nothing was aspirated, but angiomatous lesions were clinically suspected with some diagnostic difficulties. The tumor was extirpated by extraoral approach under GOF general anesthesia.
    It was diagnosed clinically as a lipoma, which was capsulated with the thin connective tissue and comprised a mass of the matured adipose tissue with multilobulation.

    An ankylosis of the temporomandibular joint in early childhood may lead to growth disturbance of the mandible. As generally described in many case reports, unilateral ankylosis caused asymmetrical facial appearance and other serious disabilities. The main etiologic factors of ankylosis are trauma and inflammation. Forceps delivery was assumed to be in our two cases, the cause of ankylosis. In young patients, opinion is divided as to the ideal age at which initial surgical opening of the joint should be performed. Recently, the operation for ankylosis is commonly performed as soon as possible. In our cases, after conservative therapy using modified FKO splint, operative relief of the ankylosis was done at the age of 13 years (case 1) and 14 years (case 2).
    In the first case, 3 years and 4 months passed after the operation. One year and 4 months passed in the second case. They have sufficient mouth opening. No relapse occured in either patient.

    Congenital aglossia is a rare tongue anomaly. There were 16 cases reported in Japan of which only one was an adult case.
    Recently we experienced a congenital aglossia case. The patient, a 20-year-old female, is the youngest of two children of unrelated parents, aged 32 (father) and 28 (mother). The patient's mother had a drugless normal pregnancy and normal delivery. The patient had sucking difficulty, but no treatment such as nasal feeding.
    Intraorally, a small extruded mass was recognized from the floor of the mouth. Both of the maxillary and the mandibular arches were very narrow, and three incisors of the mandible were congenitally missing. Radiographically, the existance of hyoid bone, submandibular, salivary gland and suprahyoid muscles were suggested by computed radiography and computed tornography. However, the patient had almost normal taste and clear pronunciation.

    Neurinoma is known to be a relatively rare disease especially in the regions of the jaw and the oral cavity. Mostly it emerges from the tongue, the buccal mucous membrane and the palate. Recently the authors experienced a case where this disease developed from the lower part of the jaw of an elderly woman of age 76. This case is reported below, together with its clinical and documentary discussions.
    The patient is a female aged 76. She had a chief complaint of swelling in the lower part of the jaw. Clinical observation revealed tumefaction of a size larger than a chiken egg in the left, lower part of the jaw. On palpation, a phyma was felt, which was movable and of relatively clear boundary. It was elastic and soft. The patient had no tenderness on pressure nor spontaneous pain. Based on the clinical diagnosis of a phyma in the lower part of the jaw, an enucleation was carried out under general anesthesia November 2, 1984. The phyma had a cover of a thin film, with no accretion of surrounding tissues. It was enucleated easily as a lump. The 40×28×22mm phyma was egg-like in shape, smooth surfaced, dark brown, soft and elastic was grayish yellow or grayish white in the divided surface.
    The inside of the phyma was filled with a bloody fluid. According to our histopathological findings, the phyma had a typical shelf-like arrangement.
    The disease was diagnosed as neurinoma (Antoni Type A). Although it is reported that this disease is infrequently recurrent and prognostically good, careful attention will be paid to the prognosis of this patient.

    Branchial cysts usually occur on the lateral sideof the neck, are believed to be derived from the branchial arch organ, and from the epithelial inclusion within the cervical lymph node.
    Recently we experienced a case of the branchial cyst on thelateral side of the neck in a 19-year-old man.
    The cyst contents were the solution like Café au lait, and showed high activity on LDH, γ-GTP and amylase by biochemical examination.
    On high activity of amylase, we suggested that adenocytes were related to derivation of branchial cysts.

    It has been considered difficult to both obtain radicality of tumors and maintain normal shape and function of the lip in minor salivary gland tumor surgery. For this reason, simple enucleation by blunt dissection has often been chosen as the method of surgery in such a case, although it might cause recurrence from residual tumor cells. A 50-year-old man who had a large tumor sized 30×20×15 mm on the upper lip was referred to our hospital on March 28, 1984. Though no positive findings of malignancy were detected clinically, simple enucleation was not carried out because it was considered an inadequate method to excise the tumor completely. The tumor and mucosa which overlaid it were excised entirely by sharp dissection, and the orbicularis oris muscle was partially dissected as a minimal safety margin for complete removal of the extra- capsular invasion. Pleomorphic adenoma was immediately confirmed by frozen section, no histological malignancy was found and radicality was also confirmed. The defect of the oral mucosa was covered by lyophilized dura with tie- over suture, and well epithelized without any deformity and dysfunction 3 weeks postop.
