    A total of 304 tongue lesions of biopsy materials taken in our department during the past 10 years (1981-1990) were clinicopathologically evaluated.
    In histological classification of the lesions, 86 (28.3%) were cancers, 58 (19.1%) inflammatory lesions, 58 (19.1%) fibroma-like lesions, 42 (13.8%) cysts and cyst-like lesions, 26 (8.6%) angiomas, and 25 (8.2%) epithelial proliferating lesions, as well as other lesions were found. As for the age of the cases with tongue lesions: 76 cases were in those between the ages of 50 and 59, 57 cases were in those between 60 and 69 years of age. And 49 cases were found in those from 40 to 49 years of age. Furthermore, the cases with cancer and the cases with epithelial proliferating lesions were found most frequently in those between 60 and 69 years of age. The cases with inflammatory lesion and the cases with fibroma-like lesion were found most frequently in the 50-59 year age group. The cases with cyst and cyst-like lesion were found most frequently in the 10-19 age group. As for the time between the appearance of symptomes and visiting the hospital, between one and two months was the most common period for those with cancer. Those with inflammatory lesions and cyst and cyst-like lesions commonly waited one month. Two years was the most common period for the cases with fibroma-like lesions. As for the correlation of the lesions with chief complaints, the fibroma-like lesion was most commonly associated with complaints of swelling. Cancer, however, was the most common in the cases which involved complaints of pain. The lateral borders of the tongue were the most frequently affected sites of the cancers and inflammatory lesions. The anterior portion of the tongue was the most common site of the fibroma-like lesions.

    Anterior displacement of the temporomandibular joint disk was evaluated in relation to the disk morphology and the osseous change using the magnetic resonance imaging (MRI). Twentysix joints of 16 volunteers without symptoms and 123 joints of 63 patients with symptoms were examined. The joint was divided into three parts; a lateral, a central, and a medial part. In each part, the disk displacement and its degree, disk morphology, reduction of the disk, and osseous change were determined. The results showed that 12-15% of anterior displacement and 4-15 % of “even thickness” shape of the disks were present in the asymptomatic group. Meanwhile, 90% of disk displacement was present in the symptomatic group. Furthermore, the lateral part of the joint had a more significant tendency to displace anteriorly than the central or medial part. The disk was biconcave in the normal case. With advancement of displacement, however, it became even-thick, and eventually convex. As displacement was advanced, the disk was irreducible and its osseous change was increased. The results indicate that the disk displacement could be related to disk deformity and osseous change.

    To elucidate the invasion mechanism of oral squamous cell carcinoma, we recently devised a new in vitro invasion model. In the present study, three kinds of oral squamous cell carcinoma cell lines (OSC-19, 0SC-20, KB) were cultured on collagen gels, and basement membrane components and matrix metalloproteinases (MMPs) produced by carcinoma cells in this model were investigated.
    Production of basement membrane components (laminin, type IV collagen, fibronectin) varied among the three carcinoma cell lines. Invasive OSC-19 cells were characterized by higher secretion of fibronectin than OSC-20 or KB cells. As to matrix metalloproteinases (MMPs), zymography using gelatin substrate gel showed serveral bands of 72kDa, 92kDa, 95kDa and 50-55kDa. By western blotting, 72kDa gelatinase (MMP-2), 92kDa gelatinase (MMP-9), collagenase (MMP-1) were detected. These enzymes were enhanced by supPlement of 3T3 cells into collagen gels. Gelatinolytic activity and collagenolytic activity were assayed, and the former was detected in OSC-19 and OSC-20 cells and the latter in OSC-20 cells.
    These results suggest that the invasive activity of oral squamous cell carcinoma is correlated with cell-matrix adhesion by fibronectin and with degradation of the matrix by metalloproteinase, especially, MMP-9 and MMP-1.

    We investigated the effects of collagen matrix on bone healing in the rabbit mandible. The collagen matrix was composed of the fibrillar collagen and the heat denatured collagen with the dehydrothermal cross-linking. This material was frozen at -30°C and freeze-dried to make a sponge-like structure.
    The sponge collagen was grafted into the mandibular bone defects of the rabbits. Histological studies were performed in one, two and three weeks after grafting.
    The sponge collagen structure promoted the infiltration of fibroblasts and newly formed capillary contrasted to the control defects. Also the bone formation in the collagen applied group was observed faster than the control group.
    As a result, this collagen matrix promoted the reconstruction process of the mandibular bone defects.

    Innervation and terminal formation were investigated in rat temporomandibular joint by immunohistochemistry for protein gene product 9.5 (PGP 9.5) both at light and electron microscopic levels. The results were summarized as follows:
    1. Nerve fibers distributed in the rat temporomandibular joint entered the capsule anteriorly and posteriorly, and some branches further extended towards medial and lateral aspects of the articular disk. No differences were observed in nerve density between the anterior and posterior parts of the diskassociated connective tissue.
    2. PGP 9.5-positive nerve fibers were not observed in the center of the articular disk, with only thin nerves scattered in the marginal portion of the articular disk.
    3. Synovial membrane contained a number of thin nerve fibers which were located exclusively at the subsynovial layer. No nerve fibers penetrated deeply into the thick synovial cell layer toward the articular cavity.
    4. Major population of nerve terminals in the rat temporomandibular joint was recognized as free nerve endings by light microscopic immunohistochemistry. At the electron microscopic level, however, those light microscopic free nerve endings were divided into two subtypes in the category of nociceptors and mechanoreceptors. The former type was much more prevalent than the latter.
    5. As regards the specialized nerve endings, this immunostaining could demonstrate the Ruffini-like endings in the lateral pericondylar tissue near the center of the condyle. In addition, coiled-and Meissner's-like nerve terminals were also observed in the connective tissue surrounding the articular disk.

    Using tongue carcinoma experimentally produced by VX2 carcinoma cell injection, the microangioarchitecture was radiographically and histopathologically examined in cervical lymph nodes with metastatic carcinoma (CLNM). The results are summarized as follows:
    1) In normal controls, the cervical lymph node (CLN) was supplied by one or two feeding arteries, arising from either common carotid, external carotid or occipital artery, which penetrated the hilus ofthe lymph node. Angiogram failed to depict the CLN, while microangiogram successfully revealed that the feeding artery ramified, after entering the hilus, to form several larger branches and then small branches distributed in dendriform fashion.
    2) The metastasis became evident five days after the inoculation. First it appeared in the marginal sinus and by day 11 spread further into the medullary sinus. The presumptive weight of metastaticareas were 0.01mg on the average at one to five days, 3.28 mg between six and ten days, and 134.68mg after eleven days.
    3) Angiogram of CLNM demonstrated a tumor stain of inhomogeneous vascular shadow when metastatic lesions reached to the deep cortex. In microangiogram, basket-like and/or irregular net-like meandering vascular structures surrounded the tumor tissue when it reached to the deep cortex of the involved lymph node. These vessels correspond to the common designation of peripheral vascularization with penetrating vessels.
    4) Histologies during the early stages of a lymph node metastasis showed paracortical hyperplasia and dendriform proliferation of post capillary venules, presumably representing immunologic response. As the tumor increased in size, the host vessels were either incorporated or displaced with various morphological changes of capillaries including neovascularization. Tumor emboli, thrombi and tumor cord formation were present.
    5) These results were considered to provide some supportive evidence for the assumption that the irregularity of angioarchitecture in CLNM influences effectiveness of radiotherapy and chemotherapy.

    The change of the parotid gland with time following ligation of the main duct was investigated. The duct-ligated parotid gland in rabbit was examined by salivary gland scintigraphy with 99mTc-pertechnetate (99mTcO4-), sialography and microscopic observation.
    The third day after ligation of the main duct, the outward form of the parotid gland on the static scintigram was not well-defined. On the seventh day, 99mTcO4-accumulationwasdecreasedslightly. On the 14th day, atrophy of the parotid gland occurred.
    The degree of atrophy produced by ligation increases as the duration of the ligation increases. On the 42nd day, the presence of the parotid gland was not recorded practically.
    The main duct was dilated on the third day. On the seventh day, the intraglandular ducts were bent and strictured. Disappearance of the peripheral duct and atrophy of the parotid gland perenchyma was observed.
    On microscopic observation, the intraglandular tributaries and the lumen were dilated on the third day. And the reticular fiber was observed that was irregularly formed in parts. The acinar cells were pressed by large and small dilated lumen on the seventh day. On the 14th day, the collagenous fiber around the acini and the duct was increased still more. In addition, fibrosis of the lobule interspace was observed. The degree of atrophy of the acini and lobule was increased maximally on the 42nd day.
    TliPCP results of the salivary gland scintigraphy closely connected with sialograms and microscopic findings. The parotid gland tissue decreases and changings of the duct system were indicated by these imaging methods in detail.

    In this study, a new fabricating method of cultured epithelium using mucosal cells was established. This method was fundamentally based on that of cultured epithelium by Green et al. (1975). This cultured epithelium showed stratification and identical morphology to physiological mucosa. The mucosal cells possessed higher proliferating ability and maintained longer biological activity than that of epidermal cells. The most important morphological characteristics of mucosal cells was in its low grade differentiation and also it kept original mucosal structures. From these results, the usefulness of this cultured epithelium using mucosal cells was indicated for the mucosal transplantation.

    The maxillary growth in patients with bilateral cleft lip and palate from infancy to four years of age following two-stage palatoplasty combined with the use of Hotz plate was studied. The subjects consisted of 30 bilateral cleft lip and palate patients (BCLP group). Serial maxillary casts and lateral roentgenographic cephalograms were used for the analysis and compared with non-cleft control group. The results were as follows:
    1. Anterior growth of premaxilla and anterolateral growth of lateral segments were observed frominfancy to the time of veloplasty (about 18 months).
    2. At the time of veloplasty, maxillary alveolar arches came into parabolic shape due to the anterolateral growth of lateral segments by growth guidance of Hotz plate.
    3. The maxilla grew anteriorly, especially lateral segments showed significant anterior growth after veloplasty to four years of age. Moreover, no statistical differences were observed in the inter-canine width and inter-first molar width between BCLP group and control group in deciduous dentition.
    4. The analysis of lateral roentgenographic cephalograms revealed that the position of premaxilla in BCLP group was the same as that of the control group throughout the observation period, however, the anteroinferior growth of lateral segments was significant.
    5. The length, width and position of maxillary arch in the BCLP group were the same as that of the control group at four years of age.
    It is concluded that two-stage palatoplasty combined with the use of Hotz plate is effective for maxillary growth in bilateral cleft lip and palate patients.

    A dental impression technique was applied for preparing a histological whole -mount specimen of the oral cavity and pharynx of the mouse. Hydrophilic vinyl polysiloxane impression material mixed with a hardening accelerator was injected into the lumen under pressure. After sufficient hardening (5 min. after the injection), mucosal tissue was removed together with surrounding glands and musculatures. The tissue blocks were dipped en bloc in the ZIO solution according to the method of Jabonero (1964) for 24 hrs. at room temperature. Tissue sheets containing various layers of the oral cavity and pharynx were prepared using a watchmaker's forceps, mounted on the glass slide, and observed by light microscopy. Three-dimensional interrelationshil-s between the nerves and vasculatures were demonstrated: both the blood vascular network and the nerve network were continuous in the median plane of the soft palate, hard palate, and boundary between pharyngeal and esophageal walls.Some whole-mount preparations were utilized for the immunohistochemical observations after fixation in Bouin's fluid. By immunostaining using an S-100b protein antiserum, Schwann cell networks of the autonomic nerve terminal apparatus appeared between the smooth muscles and salivary glands of the soft palate and other organs. The motor end plates in esophageal musculature were also demonstrated byimmunostaining using neurocalcin antiserum.
    Peculiar blood vessels existed in the periphery of the SCC VII tumors transplanted into the soft palate and pharynx; however, neither lymphatic vessels nor nerve elements were seen in those tumors. Thus the improved whole-mount method of specimen preparation is useful for the histological investigation of the mechanisms of tumor invasion and metastasis in the field of oral surgery.

    Basal cell nevus syndrome is considered to be an autosomal dominant hereditary disease. But reports of this disease with comparison of symptoms between parent and child are rare. Four cases in two families with basal cell nevus syndrome and a review of 39 cases in 17 families with this disease were reported in Japanese literature. Four cases that we recently experienced were a case of a 47-year-old mother and her 14-year-old daughter and a case of a 47-year-old father and his 14-year-olddaughter. In these cases multiple jaw cysts, palmer and planter pits, calcification of the falx cerebri, bridging of sella turcica, frontal and biparietal bossing, ocular hyperterolism, broadened nasal root, and skeletal anomalies were observed. There were some symptoms similarities between parent and child.

    Multiple malignant tumors were found in 20 of the 224 patients with malignant tumor in the oral and maxillofacial region (8.93%), who received treatment at the Second Department of Oral and Maxillofacial Surgery, Niigata University Dental Hospital, from 1974 to 1992.
    The results are as follows.
    1. In the cases of multiple malignant tumors, double cancers were found in 16 and triple cancers in 4 patients. Fourteen of the 20 patients were males and six females (2.33: 1).
    2. In the cases of double cancers, the average age of first cancers was 62.6 years and second cancers was 67.0 years. In these cases, non-synchronous cancers (an interval of more than one year) accounted for 81.2%.
    accounted for 81.2%. 3. The other regions of the multiple malignant tumors were digestive and respiratory organs (83.3%). Especially, stomach, esophagus and lung together accounted for 62.5%.
    4. 43.8% of the cases of double cancers had suffered from two cancers with an interval of more than 5 years. Consequently, the necessity of follow-up, at least more than 5 years, was revealed in the cases of malignant tumors of the oral and maxillofacial region.

    A case of rhinolithiasis which was suspected to be an odontoma occured in the patient with mental retardation.
    The 30-year-old man was escorted to our Department for consultation on September 28, 1991 with a complaint of swelling in the left buccal area. Physical examination revealed diffuse swelling and oppressive pain in the buccal portion, but no abnormal findings were detected in remaining teeth. The first X-P roentgenogram revealed a radio-opaque are within the nasal cavity. The clinical diagnosis was secondary maxillary ostitis caused by odontoma. On the demonstration of CT radiograph, a calcified focus was displayed in the left nasal cavity, thus the clinical diagnosis was corrected to be rhinolithiasis. The rhinolith was removed through an endo-nasal approach under general anesthesia. The substance was 15×10mm in size, with brown greyish color, and it weighed 1.8g. The mass was diagnosed histologically as calculus and bacterial flora.

    A fourteen-year-old boy was examined for painless lymphadenopathy in the submandibular and cervical regions. The patient was treated with incision and antibiotics, without change in the size of the lymphnodes during 3 months. Radiological examination was performed. The findings in computed tomogram and echogram revealed two masses in the left submandibular region. One mass was approximately 2cm, the other mass was 3cm in diameter. In contrasted radiographic findings of the submandibular gland, the masses were applying pressure on the left submandibular gland. The two submandibular lymphnodes were excised with the adhered left submandibular gland for excisional biopsy. Piringer's lymphadenitis or acquired lymphadenitis was suspected histopathologically. However, they were so rare in Japan that reactive follicullar hyperplasia of the left submandibular lym-phnodi were diagnosed. Toxoplasma cysts were identified and specific serology was confirmatory.

    Ameloblastoma is pathologically described as a benign neoplasm. However, wide resection of the jaws has been recommended as the treatment because of its high recurrent incidence.
    Recently, marsupialization therapy that had been used for cystic lesion has been tried for the treatment of ameloblastoma. In this report, 8 cases of ameloblastoma were analyzed in pathological and radiographic change after marsupialization therapy. The results were as follows.
    1) In radiological examination, the tumor size in 5 cases were reduced. 1 case was not changed after 6 months and has gradually become smaller. 2 cases were enlarged after marsupialization therapy. The clinical effect of marsupialization therapy appeared 6 months after the treatment in effective cases. These cases have become smaller than their original size for 12 months.
    2) In pathological examination, the histological type of the tumor revealed changed and unchanged types after the treatment.
    Thus we concluded as follows. When ameloblastoma was treated by marsupialization therapy, the effect of treatment should be judged 6 months after the treatment. In case of no effect of the marsupialization therapy, the radical resection of the tumor should be immediately planned. If the effect of marsupialization therapy was observed after 6 months, marsupialization therapy should be continued for 12 months longer.

    A tumor growing in the palate of a 72-year-old woman, which was extirpated about 30 months ago, showed histologically a pleomorphic adenoma consisting of uniform epithelial cells with myxoid stroma. The patient had a recurrent tumor showing progressive and infiltrative growth. The invasive tumor was widely excised and radiation therapy with a total of 56 Gy of linear accelerator was postoperatively given. Two years later, the patient had cervical lymph node and lung metastases and received surgical excision of these metastatic lesions. The patient is condition has been followed, and no further recurrence has occurred so far. The histopathological appearances of the recurrent and metastatic tumors were similar to those of the primary tumor except for a very mild anaplastic change of epithelial cells in the recurrent tumor and squamous metaplasia of tumor cells in the metastatic ones.
