Glandular odontogenic cyst (GOC), first described in 1988 by Gardner et. al, is a comparatively rare jawbone cyst of odontogenic origin, which shares some features with both botryroid odontogenic cysts and mucous-producing salivary gland tumors. Although GOC has a high rate of recurrence, cases of recurrence have not been reported in the Japanese literature.This paper describes a case of GOC arising in the mandible of a 58-year-old man. The cyst recurred 12 years after primary treatment. Diagnosis and treatment of the lesion are discussed.

We report a case of glandular odontogenic cyst (GOC) arising in the mandible. The patient was a 55-year-old woman who presented with a painful swelling of the right premolar region of the mandible.Roentgenographic examination revealed a multilocular radiolucent lesion from the right first molar across themidline to the left second premolar region. The clinical diagnosis was a mandibular cyst. Enucleation of the cystand extraction of the teeth were performed with the patient under general anesthesia. Histological examinationshowed a multicystic lesion partially lined by non-keratinized epithelium with focal plaque-like thickening. Thesurface epithelium included eosinophilic cuboidal and ciliated cells. Cyst-like spaces and glandular structureswere also observed within the epithelium. Epithelial islands were also seen in connective tissue of the cyst.Immunohistochemically, epithelial cells were strongly positive for cytokeratin (CK) 13 and 19, but almost negativefor CK18. The histological diagnosis was GOC. The postoperative course was satisfactory, and no recurrencehas been noted 4 years 6 months after the operation.

Vascular leiomyoma is a benign tumor of smooth muscle that mainly occurs in the hands and legs. However, it rarely occurs in the oral cavity.<BR>A case of vascular leiomyoma of the buccal mucosa is reported. A 73-year-old woman visited our department because of a swelling in the buccal mucosa. CT examination revealed a smooth tumorous lesion in the left buccal mucosa. The clinical diagnosis was a benign tumor, and enucleation of the tumor was performed. The histopathological diagnosis was vascular leiomyoma.

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.

Paralysis of the mental nerve is one of the principal complications of surgery of the mandibular canal and mental foramen region. The position of mental foramen can be clearly depicted on CT scans. The mental foramen is bilaterally located at the mandibular premolar region and appears as a dimple on the bone surface. However, several reports have described an accessory mental foramen (AMF). We examined CT pictures taken from patients with implants for missing mandibular teeth to detect variations of the AMF. The results were follows: 1) AMFs were present in 28 patients (24.6 %). 2) Unilateral AMFs were found in 24 patients, and bilateral AMFs in 4 patients. 3) Among patients with unilateral AMFs, 21 had AMFs with one foramen, and 3 had AMFs with two foramens. Among patients with bilateral AMFs, 2 patients had one foramen on each side, and 2 had two foramens on one side. 4) The position of AMF relative to that of the mental foramen was as follows: 18 foramens were superior mesial, 8 were superior distal, 6 were inferior mesial, and 5 were inferior distal.These results suggest that one quarter of patients with missing mandibular teeth may have AMFs around the mental foramen.

In the present study, inorganic pyrophosphate (PPi), Mg, alkaline-phosphate activity (Al-pase), Ca, Pi and total protein in submandibular and parotid saliva were measured in 19 sialolithiasis and 61 age-matched control subjects in order to understand the possilbe etiologic factor (s) or disposition of this disease. The results can be summarized as follows:1. Saliva constituents in control subjects1) The concentrations of PPi and Mg, which are known to be potent inhibitors of calcium phosphate crystal formation, were significantly low in the submandibular gland as compared to those in the parotid. Since available clinical and statistical data on this kind of investigation so far performed show that sialolithiasis occurs most commonly in the submandibular gland, the lower inhibitory activity in this gland might be responsible for the formation of calculus.2) The concentrations of PPi, Ca and Pi in the submandibular saliva increased with age, while no distinct relationship was demonstrated between the concentrations of PPi, Ca and Pi and age. This finding seems not coincident with the clinical observation that sialolitiasis occurs most frequently in the second, third and fourth decades of life.3) As for saliva constituents, no significant difference was observed between males and females. This finding well coincided with the clinical observation that no sex difference exists in the incidence of sialolithiasis.2. Saliva constituents in patients with sialolithiasis1) With regards to all parameters examined, there was no significant difference between saliva constituents from non-diseased submandibular glands of sialolithiatic patients and those from normal subjects. This suggests that the submandibular gland in the non-diseased side functions normally even in patients with sialolithiasis.2) The diseased submandibular glands had significantly lower concentrations of Mg and Ca as compared to normal glands, which may indicate that some local disturbancees occur in the diseased submandibular glands from patients with sialolithiasis.3) The Al-pase activity in the diseased submandibular saliva from patients with sialolithiasis was considerably higher than non-diseased submandibular saliva from sialolithiasis and control subjects, In addition, the concentration of PPi showed a negative correlation to the Al-pase activity (r=0.822, P<0.05). It is assumed tha PPi may rapidly decomposed by high Al-pase activity, ultimately leading to crystal formation together with low Mg levels in the affected submandibular glands.

To clarify both the mechanism of parapharyngeal involvement of head and neck cancers and the clinical usefulness of parapharyngeal dissection, the routes of lymphatic flow from the oral cavity and oropharynx to the parapharyngeal space were studied using activated carbon particles CH40.The following results were obtained:1. Lymphatic flow from the posterior portion of the oral cavity and that from the oropharynx reach the parapharyngeal space through lymphatic channels in the submucosa.2. Among 6 routes of direct parapharyngeal spread of head and neck cancers, the anteromedial inferior, anteromedial superior, medial central, and anterolateral routes were found to have direction-specific routes of lymphatic flow. The flow of the former 3 routes is high, and that of the later route is low. These routes of lymphatic flow were considered to be responsible for the frequent spread of cancers into the parapharyngeal space by direct extension.3. Lymphatic flow to the parapharyngeal space drains not only into the node of Kuttner but also into the parapharyngeal and retropharyngeal nodes through lymphatic vessels in the parapharyngeal space.4. Anatomically, these findings suggest that parapharyngeal dissection is very useful in the management of cancers that involve the parapharyngeal space.

Mandibular reconstruction remains one of the most challenging problems for the head and neck surgeon. Various methods of mandibular reconstruction have been described, including free bone grafts, osteomyocutaneous flaps, free vascularized bone grafts, reimplantation of treated mandibles, and reconstruction using alloplastic materials with particulate cancellous bone and marrow grafts.This paper describes the author's experience using a Dacron-urethane mandibular mesh tray filled with particulate cancellous bone and marrow for mandibular reconstruction.Six patients underwent resection of the mandible for malignant tumors, 7 for benign tumors, and 1 for radiation osteomyelitis.Immediate reconstruction was performed in 7 patients, and 5 of the 7 were successful. Delayed reconstruction was performed in another 7 patients, and 5 of the 7 were successful. The overall success rate was 71%. Mandibular reconstruction was successfully accomplished even following radiotherapy in 4 of 6 patients. The majority of the failures occurred in the first 10 days following surgery and the major factor in failure seemed to be related to intraoperative wound infection.The Dacron-urethane mandibular mesh tray has the advantage of being malleable but stiff, and can be easily cut with scissors to fit the defect. The tray is radiolucent, faciliting follow-up examinations by routine roentgenograms and radionuclide scans. It can be used either before or after radiotherapy.This reconstructive procedure is not technically difficult and does not require expertise in microvascular surgery. In selected patients, this procedure may significantly contribute to cosmetic and functional improvement following radical surgery of the mandible.

In squamous cell carcinomas of the oral cavity, spinal accessory lymph node (SALN) metastasis develops infrequently, and the prognosis of the patients with SALN metastasis is extremely poor.<BR>In this paper, patients with SALN metastasis of squamous cell carcinomas of the oral cavity were studied retrospectively. The SALN metastasis was histopathologically confirmed in 9 (5.0%) of 179 patients who underwent radical or modified radical neck dissection. The primary sites of their tumors were the tongue in 6 patients, the lower gingiva in 2, and the buccal mucosa in 1. The risk of SALN metastasis was related to the tumor spread into the oropharynx and the differentiation of the tumor, but not related to the T stage. In the patients with SALN metastasis, the mean total number of involved nodes on the affected side of the neck was 9.4. All of these patients had metastases in multiple groups of neck lymph nodes, and the majority had metastases in the upper and middle jugular groups of nodes. The mean number of involved SALNs was 2.0, and the mean size of these nodes was 0.52 cm in diameter.<BR>The outcome of treatment in the patients with SALN metastasis was poor: 1 patient was alive with no evidence of disease, and 8 patients died of disease with an average duration of survival of 8.0 months after neck dissection.<BR>To improve the prognosis of patients with SALN metastasis, both postoperative irradiation to the neck and intensive adjuvant chemotherapy should be employed.

A 56 year-old male patient with adenoid cystic carcinoma of the right sublingualgland origin was reported. In this case, extensive local resection of the tumor including the dissection of the parapharyngeal space along the lingual and hypoglossal nerves was carried out in combination with radical neck dissection. Surgical treatment was followed by 60 Gy of radiotherapy.He was free of disease during the follow-up period of 9 months.Adenoid cystic carcinoma arising in the sublingual gland accounted for 35 cases reported in the literature for the period of 1930-1984.

Reestablishment of mandibular continuity following radical surgery for oral cancer has been a challenging task to the head and neck surgeon. Treated autografts such as autofrozen or irradiated bone have been used for primary reconstruction of the mandible.The first 14 consecutive cases in which a mandibular defect was immediately reconstructed with a boiled autogenous mandible are reviewed. The defect consisted of horizontal ramus alone in 5 cases and symphysis with one or both rami in 9. The resected segment of mandibular bone was dissected free of the gross cancer, shaved and boiled in water for fifteen minutes. The treated bone was replanted with internal fixation, then intraoral and surrounding soft tissue defects were reconstructed with pectoralis major or latissimus dorsi myocutaneous flap. It is essential to the success of this procedure that the boiled autograft is enveoped with the muscle of the myocutaneous flap and all dead space is eliminated. The follow-up period ranged from 2 months to 1 year and 7 months, with a 65% success rate. There has been no tumor recurrence originating in the boiled bone. Radiographic examination of reimplanted bone revealed a gradual absorption process, but in some cases showed evidence of neo-osteogenesis at the contiguous area.Primary reconstruction of mandible with reimplantation of the boiled autogenous bone is distinguished by its ease and is a reasonable alternative in cosmetic and functional restoration.
