    Effects of local one shot irradiation (3, 5, 10 Gy) on lung metastases of VX2 carcinoma transplanted in maxillary sinus of rabbits were observed.
    Tumor growths were apt to be inhibited corresponding to given dosage. Some tumors among rabbits with single dose of 10 rabbits Gy regressed completely. However, when insufficient local irradiation for complete tumor regression was given, the incidence of pulmonary metastases in irradiated groups remarkably increased compared with non-irradiated group. If the implanted tumor was cured by the radiation, the incidence of pulmonary metastases was 0%. This evidence might suggest that non-curative irradiation to VX2 carcinoma implanted in maxillary sinus of rabbit resulted in an increased incidence of lung metastases. General conditions between irradiated and non-irradiated groups examined in this study were not significantly different, so it was suspected that local factors influenced by the radiation were also involved in this phenomenon, although further studies would be needed.

    In 1960, Rock et al reported three cases of papilloma showing u florid type of multiple fusion in the oral cavity and larynx diagnosed as florid papillomatosis. Although no malignant finding has been histologically observed in this disease, it is extremely intractable and its radical treatment is very diffcult in the clinical practice.
    We recently experienced on extended oral florid papillomatosis from the upper and lower lips to the right and left buccal mucosa in 59 year-old man. Clinically, a malignant tumor was suspected, however, the histological finding showed no malignant feature such as deep infiltration of epithelial cells and ruptured basement membrane though the epithelial hyperplasia with marked acanthosis was observed.
    Chemotherapy resulted in some therapeutic effect but failed to give a complete resolution. The discrimination of this disease from verrucous carcinoma could not be made from the pathological standpoint. However, a diagnosis of oral florid papillomatosis seemed more suitable to this case from the clinical standpoint for understanding the state of disease more accurately.

    There are many hypotheses on the formation of salivary calculi, such as inflammatory theory, microbiological theory and foreign body theory.
    Recently, we experienced an interesting case of a salivary calculus in the submandibular duct which was suspected to be formed with the nucleus of a fish-bone.
    The patient, a 37-year-old man, visited our clinic with the chief complaint of swelling in the right submandibular region. Extraoral examination showed a well-defined, smooth swelling and induration in the right submandibular region. Intraorally, a reddened swelling is noted near the orifice of the righ Wharton's duct. Saliva could not be secreted from the right orifice and a small amount of pus was discharged. Roentgenogram disclosed a well-defined radio-opaque picture at a root apical region of lower right second premolar tooth. The routine laboratory findings were within normal limits. From these findings, clinical diagnosis was sialolithiasis of the right submandibular duct and sialoadenitis.
    After the infection was controlled by administering antibiotics, the calculus in the submandibular duct was removed by incision intraorally. Two months later, total excision of the salivary gland was carried out because inflammation persisted.
    Microscopic examination of the removed submandibular gland showed atrophy or disappearance of acinic cells, and inflammatory cell infiltration. Futhermore, inter-and intralobular fibrosis was observed. As a consequence histopathologic diagnosis was chronic sialoadenitis.
    The removed calculus was 6×2mm in size, whitish yellow in color with a fish bone in the center. Microscopic and radiographic examination of the calculus revealed calcareous deposit around this fish bone. Therefore, it was suspected that the salivary calculus was formed around fish bone.
    This is considered to be an interesting case which may suggest foreing body theory

    Five cases with mean age of 48.6 years, in which the extraction of the mandibular third molar was too diflcult for the usual technique, were reported. The cause was tooth bone ankylosis and/or osteosclerotic changes in the surrounding alveolar bone. For these extractions, extensive removal of bone around the teeth was necessary and the split bone technique was especially useful.

    Ten years old girl who had osteosarcoma of the mandible, received monthly high dose methotrexate therapy (100mg-200mg/kg) thirteen times as a adjuvant chemotherapy after radical operation. As side effects leukopenia (minimum 2, 600/mm3) and vomiting were frequently observed. Neither renal functional abnormality nor other severe side effects were noticed.
    There was no evidence of tumor recurrence or metastasis while two years after the radical operation.
    Thus high dose methotrexate therapy is effective on jaw bone osteosarcoma. However, optimum hydration of the patient, alkalinization of the urine and periodical measurement of serum methotrexate concentration are necessary to perform this regimen without fatality.

    A case of osseous choristoma of the tongue in a 27-year old man is described. The lesion appeared as a pedunculated mass measured about 1.0 by 1.0cm, on the dorsal surface of the left posterior third of the tongue. The patient stated that the lesion had been present for about twenty years. The mass was excised under general anesthesia. Rentogenogram of the excised material revealed a well-circumscribed radiopaque nodule within the mass. Histologically the lesion consisted of a well-circumscribedmass of dense lamellar bone. Haversian canals were seen, as well as osteocytes in the lacunae. The bony mass was surrounded by dense fibrous connective tissue with stratified squamous epithelium of the lingual surface. The ulcer formation was partially observed in the overlying epithelium with seconday inflammatory changes. There have been very few reports of the osseous choristomas in the oral region. To date, Thirty-six cases have been reported in the world literature. The present report is the fourth case in Japan.

    Reported is a case of squamous cell cartinoma of the lower lip that spread along the inferior alveolar nerve to the cranium, and also retrogradelly spread down to the other divisions of the fifth nerve.
    One year after radical operation of the primary lesion, the patient began to have the sensation of something chewing his tongue. This was 2 months before observation of a recurrent mass around the mental foramen region. Roentgenograms revealed widening of the mental foramen, the mandibular canal, and the foramen ovale. Invasion of cancer through nerve sheath was suspected because of these findings. Hemimandiblectomy was carried out 48 days after the recurrence. A frozen section was applied in order to secure the surgial margin during the surgicl procedure. Histopathologically the inferior alveolar nerve, the mandibular nerve just under he foramen ovale, the lingual nerve and the mylohyoid nerve revealed invasion by the cancer.
    After the operation, as the spread of the cancer into the cranium was suspected, 60Co therapy including the base of the skull was tried, but the patient died 34 months after initial inspection.
    Attention is again called to the fact that spread of carcinoma along nerve sheath is a common pattern.

    We recently experienced a case of large palatal fistula after plastic operation, for which a fisturectomy was perfomed using an island mucoperiosteal flap with a favorable prognosis.
    Merits of this method:
    1) Even large palatal fistula can be closed with this flap.
    2) The island flap moves easily to the anterior or lateral portion of hard palate.
    3) The result is ensured because the flap contains a major palatine neurovascular bundle.
    4) This operation requires only one stage procedure and can be applied to infants and children.
    Demerits of this method:
    1) This technique is inadaptable for wide fistulas of hard palate.
    2) A careful management of maxillary development is required when this method is used in children.

    A 48-year-old woman who had a radicular cyst of the right upper anterior teeth wa diagnosed as aymmetrical septal hypertrophy (ASH). In the echocardiogram the ventricular septum was disproportionately thickened compared to the posteriorbasal left ventricular free wall. The electrocardiograms revealed abnormal Q waves in Lead 3.
    For premedication, minor tranquilizer was given to the patient, 10 mg internally 30 minutes before surgery. Extraction of the right upper lateral incisor, apicoectomy of the right upper central incisor and canine and marsupialization of the radicular cyst were performed under local anesthesia. 1% lidocaine without Epinephrine, 4ml was used as the local anesthetics. No abnormal signs were noted during and after the operation.
    It is important for the dentsit to take the patient's personal and family histories because ASH is frequently transmitted genetically. If there had been a case of sudden death in the family, possibility of ASH must be kept in mind.

    Malignant lymphoma is a generic name given to the neoplasms arising from the lymph node and lymphoid tissues.
    We report here the process of the treatment and the analysis of the histological features of three cases which were classified as stage I of non-Hodgkin's lymphoma according to the stage classification settled at the Ann Arbor conference. The tumors of all three were confined to unilateral submandibular lymph node region. The radiation therapy after surgical procedure, extirpation of the tumor, was done in such a way that the target might absorb a total dosage of 4, 000 rads in 4 weeks. Prophylactic irradiation with 4, 000 rads was also delivered to the entirety of Waldeyer's ring, the neck and surpraclavicular fossae.
    Radiotherapy has been the treatment of choice for the large majority of patients with non-Hodgkin's lymphoma localized nodally or extranodally in stage I to II.
    The analysis of the histological feature: The three cases were all diffuse lymphomas. Two cases were classified as the histiocytic type, and the other was classified as the mixed lymphocytic and histiocytic type by Rappaport's classification. According to LSG (Lymphoma-Study-Group) classification, the three cases were classified as the pleomorphic type, the mixed type and the large cell type, respectively. All of them have been progressing favorable with a tendency of remission but no evidence of relapses for the past 6 years, 4.5 years and 2 years, respectively, since surgical and radiological therapies.

    Six cases of lingual mandibular bone concavity are reported in this paper with review of the literature. This concavity is usually seen between the mandibular canal and the inferior border of the mandible, just anterior to the mandibular angle. This condition is also seen in the anterior portion of the mandible.
    A variety of terms have been applied to this bone concavity, including static bone cavity, static bone defect, latent bone cyst, idiopathic bone cavity, aberrant salivary gland tissue in the mandible, developmental bone cyst, and so on. Recently, the term, lingual mandibular bone concavity, is thought to express this condition most precisely. Since Stafne described this condition in 1942, numerous cases have been reported in the English literature. In Japan, however, only 49cases have been reported in the available literature.
    Of our cases, five were present in the posterior portion of the mandible and one in the anterior portion. All our cases occured in males over the fifth decade. Under the clinical diagnosis of mandibular cyst, the one in the anterior portion was treated surgically and its content was examined microscopically. Microscopic findings revealed normal sublingual salivary gland tissue. From the result, the diagnosis of lingual mandibular bone concavity was made. another cases were diagnosed by clinical and radiographic findings These cases are now kept under observation.
    Of 55 cases reported in the Japanese literature including our 6 cases, 51 cases occured in males. Although, no site distribution was reported previously, our study revealed an inclination to the left side. Most of contents were salivary gland tissue, but fibrous connective tissue and fatty tissue were occasionally involved. It is suggested that salivary gland tissue changes to fibrous connective tissue and fatty tissue with aging. Therefore, salivary gland tissue is considered to play an important role in the formation of this condition.

    In 1962, Kempe first described a clinical picture of children who have received physical abuse from their parents or foster parents as a battered child syndrome.
    We recently experienced a case of the battered child syndrome with oral candidiasis and mandibular fracture. A female infant of 1 year and 1 month post partum was referred to our hospital because of malnutrition and multiple unexplained trauma. Radiological studies revealed subdural hematoma and mandibular fracture, while the intraoral examination revealed extensive pseudomembrane and severe stomatitis.
    The patient was suspected of battered child syndrome and hospitalized so as to isolate from her mother. General management subsequently performed including chemotherapy, fluid therapy, blood transfusion and supply of nutrients saved the patient from death.

    A rapid progress of reconstruction procedures in recent years has greatly helped in the improved prognosis after operation in the maxillo-facial field.
    A forehead flap is widely used for reconstructing or covering a defect on the posterior and for lateral part of oral cavity and usually requires two phase procedure. Thus, the time required for reconstruction is prolonged. In addition, a large defect may be left on the frontal or temporal area.
    According to a conventional flap classification, this forehead flap is considered to be of axial pattern flap. Above mentioned problems may be partly overcome by preparing a vascular pedicled flap of this type.
    In this article, five cases of vascular pedicled forehead flap, i. e., forehead island flap reconstruction are presented with the results as follows:
    1) Forehead island flap allows one stage reconstruction, therefore resulted in a shortened peniod for hospitalization.
    2) This flap usually leaves a smaller donor defect than conventional forehead flap, providing a seightly improved asthetic difficulties.
    3) As compared to other flaps, this flap has less contraction so that a flap sized from the same as the 10% larger than that of defect is sufficient to obtain an adequate island flap.
    3) For ensuring venous drainage, it should be minded to prepare a wide pedicle and to follow the subcutaneous layer and supra-periosteal layer accurately.
    5) The application must be carefully selected in aged patients with vascular disease.

    The aneurysmal bone cyst is a solitary cystic lesion of bone was first described as a distinct clinicopathologic entity by Jaffe and Lichtenstein in 1942. The lesion is usually found in the long bones and vertebral column. The lesion is rare in the jaws. We present a case of aneurysmal bone cyst of the mandible.
    A 9-year-old girl was referred with swelling of the left side of the mandible. She had noticed the swelling approximately 1 year previously. She first visited on other oral surgeon who operated with the diagnosis of ameloblastoma, but operation was discontinued because of profuse hemorrhage. Subsequently the swelling had increased and she was referred to our clinic.
    On examination, the patient was found to be generally in good health. There was an expansion of the left body of the mandible. Intraoral examination revealed a relative firm swelling, extending from the lower left central incisor to the retromolar region in the left side, buccaly and lingually. The mucosa over the area was normal. Palpation disclosed a bony hard expansion of the mandibular cortex, and eggshell crepitus was present in the region of the lower left canine and the first premolar. Radiographs revealed a multilocular radiolucent area, extending from the lower right second incisor to the retromolar region in the left side. Angiography of the left common carotid artery showed normal findings. Full blood examination and serum analysis were within normal limits. Exploratory aspiration was performed and bloody contents were obtained continuously.
    Under general anesthesia, the left inferior alveolar artery was ligated, and then all cystic tissue was removed from the cavity by careful curettage intraorally. Histologically, the lesion consists of a fibrous connective tissue stroma containing numerous capillaries and blood filled spaces. In some regions, new bone formation and diffuse hemorrhage were seen. A few giant cells were present. The lesion was diagnosed as an aneurysmal bone cyst. There were no signs of recurrence 2 years after operation and radiograph revealed regeneration of bone in the area of the lesion.

    Although it is natural to completely remove the tumorous tissue in the operation of labial tumors, especially cancer of lips, it seems important to attempt the patient's prompt social return by performing immediate reconstruction in order to improve functional and aesthetic defects occured in the site of operation.
    In the present study, we performed an immediate reconstructive operation according to Fries method, a modification of Bernard method, using a local flap in patients with squamous cell carcinoma of the lower lip. In consequence, an almost satisfactory result was obtained from both functional and aesthetic standpoints, which will be reported in this paper.

    Central carcinoma occurred in the mandibula of a 49-year-old man which had been observed radiologically over about 7 years was clinically and pathohistologically examined.
    The histological origin of jaw-centralized cancer is an odontogenic cyst in most cases, but those originated in the aberrant epithelium are rarely encountered. However, the established histological origin was unclear in this case.
    Radiographically, a bone resorption in the surroundings of the inferior alveolar nerve bundle and irregular bone resorption in the mandibular ramus were predominantly observed in his right mandibula.

    Clinical and histological observations of 17 cases of plunging ranula were reported.
    1) There were 7 male and 10 female patients. The youngest patient was 0 year old, and the oldest was 44. Most of the cases occurred in the patients below the age of 20.
    2) In this series of 17 cases, plunging ranulas were classified into five types based upon the extensive pattern into the cervical regions. type I:7 cases. type II: 3 cases. type III: 3 cases. type IV: 1 case. type V: 3 cases.
    3) Extription of the sublingual gland is the logical approach to obtain a definite cure.
    4) Most plunging ranula are due to the extravasation of mucous from the sublingual gland. But congenital plunging ranula may be due to the retention of the mucous from the sublingual or submandibular gland.
