JOURNAL FREE ACCESSFollowing right submandibular lymphadenectomy in Wistar rats, one of the bisected normal lymph nodes was autotransplanted to the vacant space from the left side without microvascular anastmosis.
The transplants, especially in the subcapsular sinus, were examined for propriety of survival, phagocytosis and their ultrastructural restoration by transmission electron microscope.
At four days and one week, a part of the transplants was nerotic and lymphoid cells had almost disappeared. But stromal cells, such as lymphendothelial cells including reticulum cells, remained and fundamental structures of the subcapsular sinus had been preserved.
Restoration of the transplants began at one week, and fibrils, formed by lymphendothelial cells, were initially irregular in size but grew regular and lymphocytes increased in the subcapsular sinus with time. After four weeks, transplants demonstrated normal histology and function, and indicated no regressive degeneration even at twelve weeks. Lymphendothelial cells, characterized by plasmalemmal vesicles and intermediate junction like structure, did not show distinct phagocytosis in the normal condition. But they possesed many organella in cytoplasm and uptaken latex particles markedly in an active restoration process. Meanwhile, the lymph node does not reform after complete excision in the left side.
The present study suggested that the free autotransplantation of bisected lymph node is an effective method for the reconstruction of lymph node function.View full abstractDownload PDF (22437K) -

JOURNAL FREE ACCESSTongue injuries are caused mechanically, thermically, chemically and radiologically, etc., but these lesions and healing processes seem to have been less studied.
The authors examined tongue injuries by acid or alkali substances, and discussed some problems about the healing process.
Experimental methods:
Six-week-old Wistar strain male rats were used as experimental animals. HC1 was used as acid, while NaOH used as alkali. The concentration of each chemical used in this study was 10, 20 and 30% diluted aqueous solution with application time of 1 minute. These experimental animals were generally anesthesized with Nembutal and the afilter paper sufficiently soaked with HCl or NaOH was applied to the anterior 2/3 part of tongue dorsal surfae.
Thirty day-research was made on tongue damage and recovery which were examined by light and scanning electron microscope.
Experimental results:
Macroscopically, no remarkable change occurred by HCl or NaOH, but light and scanning electron microscopic examinations revealed the tongue injured by increased drug concentration and considerably destroyed taste buds of fungiform papillae. One or two weeks after the tongue injury, these damaged areas showed healing of the filiform and fungiform papillary wounds, and 30 days after the injury they showed regeneration with an almost normal structure of the taste bud. In this case, however, though usually a fungiform papillary taste bud has a taste pore, some of the regenerated taste buds had several taste pores, a very intresting finding in terms of the regeneration mechanism.View full abstractDownload PDF (15210K) -

JOURNAL FREE ACCESSThe facial antral wall is composed of very thin compact lamellae. So, in the treatment of zygomatic bone fractures, simple mini plate application is sometimes difficult or inadequate for proper stability.
The mini double plate developed by Paulus and Hardt has two plates on one side of its arm, and in the immobilization of zygomatic fractures, the facial wall of the maxillary sinus can be stabilized with it due to the surface stress and tensile effect of the plate arm on the osseous lamellae between the two plates.
Recently, we introduced a mini double plate in two cases of zygomatic bone fractures and had a successful course.
This is a report of our experience concerning the treatment.View full abstractDownload PDF (7283K) -

JOURNAL FREE ACCESSIt was recognized that operation was the most successful therapeutic method for treatment of malignant melanoma. However, the primary malignant melanoma of the oral mucosa did not allow a wide surgical excision and prognosis was unfavorable in most cases. This paper described a case of operation using carbon dioxide laser instead of surgery.
A 57-year-old man visited our clinic with a complaint of pigmentation on palate mucosa. Intraoral examination revealed a mottled black-brown area on the hard and soft palate.
Their surfaces were smooth except the lesion with a small swelling on the center of the tumo r.
Clinical diagnosis was a suspected malignant melanoma. Chemotherapy with VCR, ACNU and D TIC was performed, resulting in no regression. Then, we performed a radical neck dissection for left submandibular lymphnode, an upper neck dissection for right submandibular lymphnode and laser surgery with CO2 laser for platate. The lesion was vaporized at an output of 10-30 W with the defocused and continuous wave.
After the surgical procedure, patient received adjuvant chemotherapy with VCR, ACNU and DTIC, and immunotherapy with TFT-310. At follow up 3 years postoperatively, the patient was free of symptoms.View full abstractDownload PDF (5732K) -

JOURNAL FREE ACCESSScleroderma is divided into circumscribed and diffuse types, the latter was designated as progressive systemic sclerosis. The prognosis of this disease is poor due to the internal organs being affected. In 1942 Klemperer established that progressive systemic sclerosis fell into the collagen disease category.
This paper reports a case of a 40-year-old woman accompanied by several oral findings. This case had Raynaud's phenomenon, sclerodactylia and facies sclerodermatica as general findings and ankyloglossia, trismus, smooth tongue, resorption of the alveolar bone and denture fibroma as oral findings.
The laboratory findings showed an increase in n-RNP-antibody, IgA and IgG.View full abstractDownload PDF (5233K) -

JOURNAL FREE ACCESSThe aim of oral hygiene of elderly bedridden in-patients is to reduce the excessive growth of fungal pathogens in the gastrointestinal flora.
The clinical effect of mouth care for 30 days of elderly bedridden patients in Yokawa Hospital of Hyogo was examined in this study.
The change of Candida colonization before and after mouth care was checked as the oral hygiene index.
Patients were put into A, B and C groups according to the mouth cleaning solutions used.
A. Azulene group (male 9 and female 18, mean age 79.0 years)
B. Fungizone syrup® (1mg/ml) group (male 8 and female 17, mean age 78.4 years)
C. Saliva Orthana® (Orthana Ltd., Denmark) group (male 8 and female 19, mean age 77.2 years)
Saliva Orthana® is a mucin-containing saliva substitute and was used as one of the oral cleaning drugs.
The detection rate of Candida albicans and Torulopsis glabrata before and after mouth care in B and C groups was compared with that of A group. Decreasing coefficients in Candida albicans (KA) and Torulopsis glabrata (KT) were calculated using the following respective equation
KA or KT (Detection rate (%) in B (C) group before mouth care)-(detection are (%) in B (C) group after mough care)/(Detection rate (%) in A group before mouth care)-(detection rate (%) in A group after mouth care)
The results were as follows:
1) KA in B group was 2.2 and KA in C group was 1.0.
2) KT in B group was 5.4 and KT in C group was-2.0.
3) The most effective method of oral hygiene was to use Fungizone syrup® 1mg/ml. Saliva Orthana® proved to be of benefit for suppression of the excessive growth of genus Candida except Torulopsis glabrata.View full abstractDownload PDF (616K) -

JOURNAL FREE ACCESSCentral fibroma is a rare, benign tumor which may be found in either the maxillaor the mandible.
We recently experienced a case of central fibroma arising in the left maxilla of a 18-year-old female. The clinical course is described in this paper.
The tumor in this case was excised under general anesthesia. From histological examination, the diagnosis of central fibroma was made based on the fact that the tumor is composed of spindle shaped fibroblasts and few interspersed collagen fibers, and that it contains small odontogenic epithelial rests.
The prognosis of this case is favorable with no sign of relapse.View full abstractDownload PDF (6217K) -

JOURNAL FREE ACCESSAn osteochondroma is a tumor of bone and cartilaginous elements. Its occurrence in the mandibular coronoid process is relatively infrequent. We experienced a case of osteochondroma of the coronoid process.
Patient, a 17-year-old female with the chief complaint of jaw movement restriction was referred to our clinic. The mandibular opening impairment gradually increased over the last 10 years. Her face was not asymmetrical but she had discomfort in the region in front of the ear during jaw movement. The maximum separation between the upper and lower central incisor teeth was 7 mm. X-ray examination revealed an extensible and bulbous image of the coronoid process. The treatment was surgical excision of the lesion. The lesion was removed by manipulation of the zygomatic arch resection. The mandibular opening wa in creased to 30 mm. 4 months postoperative.
The diagnosis of lesion of coronoid process requires precise clinical and X-ray examinations, and the occipito-mental radiogram was demonstrated good for diagnosis.View full abstractDownload PDF (6112K) -

JOURNAL FREE ACCESSThirty-four cases of mandibular prognathism treated with intraoral oblique sagittal splitting osteotomy were evaluated retrospectively by cephalometric analysis of skeletal changes of the mandible during at least 6 months after surgery. The subjects were 17 cases of prognathism and 17 cases of prognathism with anterior openbite.
In those cases of prognathism alone, the distal segment (represented by the point labelled Gn) and the proximal segment (represented by the point Go) were surgically reduced posteriorly parallel to the SN line. In those cases with openbite, the distal segment was surgically mored postero-superiorly and the proximal segment postero-inferiorly.
During intermaxillary fixation, the distal segment remained stable, but the proximal segment returned to the almost preoperative position in both groups of subjects. Until 6 months after releasing the fixation, the distal segment moved antero-superiorly and the proximal segmentinferiorly in the group with prognathism alone. In the other group, both segment remained stable.
After 6 months, both segments remained stable in both groups.
However, the total degree of mandibular regression was so slight that none of cases relapsed to edge-to-edge or Class III malocclusion during the follow-up period.View full abstractDownload PDF (2049K) -

JOURNAL FREE ACCESSHemangioma of the joints are commonly found at knee joints, however, in the temporomandibular joint (TMJ) region juxta-articular hemangioma cannot be found in the literature.
We experienced a case of hemangioma of the TMJ and reported it. The patient was a 67-year-old woman with complaints of the tumor of the left TMJ region and pain during jaw movement. The tumor was elastic, soft, fluctuated, no tenderness to palpation and adherent to the underlying tissues. The volume change was seen with movement of jaw. When this mass was punctured, 1/ml of blood-like liquid was aspirated. The rentogenographic examination offered no findings, but the contrast radiography of the tumor showed radioopaque figure on the lateral side of the left TMJ, which disappered in 15 minutes. The tumor was removed under local anesthesia, and was found under lateral ligament of TMJ, but was not adherent to the capsule. The microscopic diagnosis was venous hemangioma.
There were no signs of recurrence at the last examination 5 years postoperatively.View full abstractDownload PDF (6074K) -

JOURNAL FREE ACCESSThis study is based on an analysis of biopsy specimens that were diagnosed histopathologically in the Department of Oral Pathology, Tokushima University School of Dentistry from 1979 to 1983. This paper is presented with special reference to the oral mucosal lesions and other lesions except tumorous and cystic lesions in this series.
1. The total number of cases related to oral mucosal lesions during these five years were 160, that is, 12.8% of all cases.
2. The most common lesion of the oral mucosa was epithelial dysplasia (47 cases), followed by fibrous polyp (43 cases) and denture fibrosis (14 cases).
3. The epithelial dysplasia was found in the older age group and most frequent site was the gingiva, followed by the tongue and buccal mucosa.
4. The most common lesion except tumorous, cystic and mucosal lesions was radicular granuloma (43 cases) followed by epulis (38 cases).
5. Radicular granuloma was found in anyage and the most common site was the gingiva of maxilla. Microscopically, cases of 30.2 per cent contained epithelium within the granuloma.
6. The epulis was observed in anyage and more frequent in the maxilla. Microscopically, cases of 60.5 per cent were epulis granulomatosa and fibrosa.View full abstractDownload PDF (975K) -

JOURNAL FREE ACCESSAlthough cementoma is one of the odontogenic tumors, its pathological features are complicated and sometimes difficult to distinguish from bone diseases. So it is categorized as a fibro-osseous lesion. According to the WHO classification, it is classified into four lesions. However we sometimes encounter the lesions of a mass composed only of the cementum which is not described in above classification.
In the present report, we studied 9 cases of periapical cemental dysplasia and 13 cases of massive lesion which we had experienced in our department.
Both lesions occured in middle-aged and old women and ivolved mandibular molar regions. Radiologically, they appeared as well defined opaque figures circumscribed by thin lucent zones. The lesions located in the periapical regions were smaller than those located in the edentulous regions. Periapical cemental dysplasias produced various combinations of trabecular, spherical hard tissues and they fused to become large masses. Various stages of maturation could be seen in each hard tissue. Massive cemental lesions affected older patients more often than the periapical cemental dysplasias. Histologically, the lesion consisted of a large cemental mass, resembling mature bone. Most of the lesions were infected and associated with abscess.
We found a process of development from periapical cemental dysplasia to massive cemental lesions, but there still remain many problems before concluding that the latter lesion is the mature inactive stage of the former lesion.View full abstractDownload PDF (10099K) -

JOURNAL FREE ACCESSWe are presenting a case of a lymphoepithelial cyst observed in the kit lateral cervical region of a 27-year-old female. At the time of the initial examination she was in the ninth month of pregnancy, and had an elastic soft, chicken eggsized localized tumor in the left lateral cervical region. After childbirth, the tumor increased in hardness, and showed a tendency of enlargement.
The contained fluid was not aspirated in an exploratory puncture.
The 7×4×3 cm tumor was excised and found to be filled with a yellowish-white fluid.
In the histopathological findings, the cyst wall was lined with stratified squamous epithelium presenting parakeratosis, and many lymphatic tissues were noted beneath the epithelium. Furthermore, lymph nodules were noted immediately below the thin capsule covering the cyst.
3 years have passed since the operation and the course is at present good without signs of recurrence.View full abstractDownload PDF (8483K) -

They were studied in terms of clinical statistics, yielding the following results.
1. The percentage of subjects at Hellman's occlusal developmental stage IV A was 87.0 %in patient group and 80.0% in normal group. The mean age was 15.8 years old in patient group, 17 years old in normal group.
2. Angle's classification II and III were seen in 42.6% and 29.6% of patient group, 15.0% and 3.3% of normal group.
3. The percentage of subjects with malocclusion was 90.7% in patient group, which was greater than that of normal group (60.0%). The most malocclusions in patient group were upper protrusion (29.6%) and crowding (53.6%). In normal group, 20% had upper protrusion and 33.4% had crowding.
4. Of the subjects in patient group, 25.9% had 31 dentes, which was greater than the 11.7% having 31 dentes in normal group.

JOURNAL FREE ACCESSAn association between cyst and tooth was suspected in 41 (28.1%) of 146 postoperative cysts of the upper jaw diagnosed in our Department during 8 years from 1976 to 1983. The cysts were divided into 2 types on the basis of the clinical, radiological and operative findings. Type 1, which showed rich granulation at the sinusal base, amounted to 78.0% of the total. Type 2, which suggested formation of odontogenic granules at the site of apical destruction, amounted to 22.0%. This strongly suggested that radical surgery of chronic sinusitis should be combined simulatneously with dental treatment, if damage to apex dentis is suspected.View full abstractDownload PDF (4949K) -

JOURNAL FREE ACCESSThe malignant fibrous histocytoma (MFH) is an uncommon tumor of histocytic origin. It is a difficult tumor to diagnose, and may have an unpredicatable and confusing clinical cause.
A case of MFH of the mandible was reported. A 49-year-old man was visited our hospital because of swelling of the left cheek. Radiological investigation was showed the tumor of the left cheek invading the surrounding tissue with bone destruction. Microscopically, pleomorphic cells, collagen fibers and storiform pattern were seen.
A high dose methotrexate (MTX) with citrovorum factor (CF) rescue therapy was utilized in the management of osteogenic sarcoma. Prerequisites for this treatment inculuded a normal creatinine clearance and hemogram. Side effects were stomatitis, myelosuppression, nausea and vomiting, convulsions, and abnormalities in renal and liver function studies. In this case, a hight dose MTX with citrovorum factor rescue therapy was administered in combination with vincristine. As side effect, vomiting was observed. Neither renal fanctional abnormality nor other severe side effects were noted.
This therapy is effective for MFH of the mandible. However, optimum hydration of the patient and alkalinization of the urine are necessary to perform this therapy without fatality.View full abstractDownload PDF (8324K) -

JOURNAL FREE ACCESSUtilizing submucosal connective tissue pedicle flap is one of the best methods to close oroantral fistula, though it requires skillful technique and a fair amout of time. Therefore, the author devised an easy technique to separate the pedicle flap with periosteum from mucosal epithelial layer. The technique is to penetrate several straight needles into the connective tissue just under epithelial layer, holding the tips of all needles with a hemostat, and to slice off the mucosal layer by scalpel, keeping contact with needles. It takes several minutes to insert needles and a few minutes to slice off and form a connective tissue pedicle flap.
By adopting this technique it is easy to form an island flap.
Since 1981 the author had 15 cases of oroantral fistula and received good results in all.View full abstractDownload PDF (8944K) -

JOURNAL FREE ACCESSRecent advances in microsurgery have enabled one stage reconstruction of free skin flaps.
Forearm flaps are widely used in these free skin flaps, and it is assumed that the mobility of the residual tongue will be preserved. In this report, our surgical experiences of the forearm flaps in two cases of carcinoma of the tongue are presented. One case is a radial forearm flap and the other is an ulnar forearm flap.
The results indicate that forearm flaps are better than myocutaneous flaps in reconstructed tongue function. Moreover, the surgical intervention of the forearm flaps is less than that of the deltopectoral flap or the pect oralis major myocutaneous flap. From these results, it is supposed that forearm flaps will be most suitable for reconstruction of the tongue and the floor of the mouth.View full abstractDownload PDF (8527K) -

JOURNAL FREE ACCESSThe lateral tongue flap which was first described in 1956 by Klopp and Schurter is a pedicle flap from the lateral border of the tongue to the defect after resection of malignant tumors. The excellent blood supply to the tongue means that few complications occur, therefore this flap is probably indicated in irradiated cases. In this paper, three cases using the lateral tongue flap following resection of malignant tumor which have been preoperatively irradiated are reported.
Case 1: Squamous cell carcinoma of the left buccal mucosa. 45 Gy radiation was given preoperatively and 25.2 Gy postoperatively.
Case 2: Squamous cell carcinoma of the right buccal mucosa and gingiva. 73.8 Gy radiation was given preoperatively.
Case 3: Squamous cell carcinoma of the left retromolar trigone. 67.8 Gy radiation was given preoperatively.
In every case, partial separation of the suture and necrosis of the distal part of the flap were observed in 5-10 days after the operation. Case 1, the separation and necrosis healed in 4 months after the operation. Case 2, these healed in 2.5 months after the operation. Case 3, although the partial separation of the suture partly remained, the necrotic tissue was replaced with granulation tissue and epithelized.
The remnant tongues in our cases had no complications in swallowing and articuration.View full abstractDownload PDF (9188K) -

JOURNAL FREE ACCESSLymphoepithelial cyst (branchial cyst) often occurs in the lateral cervical region but rarely seen within the parotid gland. In Japan, as far as we could find in the literature, there have been only 15 cases of lymphoepithelial cyst within the parotid gland. In this report, we discuss a case of lymphoepithelial cyst within the parotid gland which we experienced clinically.
The subject is a 57-year-old male who appeared at our hospital with the chief complaint of swelling of the left parotid gland. A 32 × 43 mm tumor was palpable in the left parotid gland region. Resection of the tumor was performed under general anesthesia, and it turned out to be a single vesicle cyst having lymphoid tissues with some germinal centers in the wall. It was diagnosed histopathologically as lymphoepithelial cyst. At present, a year and 7 months postoperatively, the patient is remarkably well.View full abstractDownload PDF (5749K) -

JOURNAL FREE ACCESSThe patients in the field of oral surgery often experience difficulty in taking a natural food due to the stomatitis caused by radiation therapy and immediately after operation.
Therefore, they need a positive enteral hyper-alimentation for enabling them to good general condition.
This time, We prescribed Clinimeal for 20 oral surgery patients and examined clinical results. Side effects were observed in 8 of the 20 patients (40%), but none had to discontinue dosing. Body weight decreasing rate was 1.8% on the average, and the effective rate was 95.0% in our judgement. Thus Clinimeal was found to be useful nutriment in enteral hyperalinentation.View full abstractDownload PDF (743K)
