We report a pseudoaneurysm that developed after tooth extraction and was treated by transcatheterarterial embolization (TAE). The patient was an 84-year-old woman. Immediately after lower second molar extraction, remarkable swelling developed in the sublingual region. Slightly prolonged bleeding from the second molarregion of the right lower jaw was noted after extraction. The bleeding was controlled by local hemostatic material.On the third day after the extraction, swelling of the sublingual region increased and extended to the floor of themouth. The site corresponding to the wound after extraction showed a pseudoaneurysm on cystographic MRI. Weperformed hemostasis by TAE. The day after TAE, the pseudoaneurysm had disappeared on cystographic CT.The postoperative course was uneventful, without further bleeding.

Sixty dentigerous and 10 primordial cysts were examined clinically and pathologically. Fifty-six of the dentigerous cysts had non-keratinizing epithelium and 9 of the dentigerous cysts had keratinizing epithelium. However, 5 keratinizing dentigerous cysts and 1 non-keratinizing primordial cyst were observed as exceptions.Radiographically, the dentigerous cysts were generally of unilocular round shape with a well-defined border. However, the well-defined border was often lost due to severe infection. In contrast, the primordial cysts were more frequently shown to be of irregular and multilocular shape, and the well-defined border was well preserved even with severe infection. Thus, keratinizing epithelium was suggested to be involved in the formation of irregular and multilocular shape and to be more resistant to infection.Pathologically, non-keratinizing epithelium often showed proliferation, a lacy appearance, and ridge elongation in association with inflammatory cell infiltration. In contrast, such changes in keratinizing epithelium were rarely observed even with heavy inflammation. Interestingly, ameloblastoma-like epithelial proliferation and calcification in the absence of inflammation were partially observed in 6 and 7 cases, respectively, independent of keratinization of epithelium. Thus, odontogenic epithelial cells were suggested to have high proliferative and differentiative activities.

Squamous cell carcinoma arising in a dentigerous cyst is extremely rare. Diagnosis requires microscopic evidence of the transition from benign cystic epithelium to squamous cell carcinoma.We report a histopathologically documented case of squamous cell carcinoma showing malignant transformation within the wall of a dentigerous cyst. A 43-year-old woman was referred to our department for diffuse swelling of the left cheek associated with a small fistula of the buccal mucosa. Radiographic examination showed a round translucent image containing an impacted tooth in the left side of the maxilla. Squamous cell carcinoma was confirmed by excisional biopsy, and partial maxillectomy was performed. Histopathological examination of the resected specimens showed transition of the normal cystic epithelium to squamous cell carcinoma. The patient has been followed up for 4 years 5 months, with no evidence of recurrence.

Gas producing infections are considered to be rare in occurrence in the head and neck. A case of non-clostridial infection of which cause was unclear is reported.A 84-year-old woman was refered to our clinic with a chief complaint of swelling in the face. She had marked swelling of he right face and neck regions. The radiological finding of the face showed abundant gas in the soft tissue.The cultured face abscess revealed a growth of Bacteroide splanchnicus.Clinical diagnosis was phlegmon. A surgical excision about 5×4 cm in size was made in the necrosis tissue of the buccal, and an incision and curettage were performed in gas producing abscess of the right face, neck and chest. After operation, the data of laboratory examinations (4.8×104/m of platelet, 45% of prothrombin time) suggested disseminated intravascular coagulation (DIC). Gabexate (FOY®) and Heparin were immediatly administered, and the hematological examinations required 3 weeks to improve.In spie of irrigation, antibiotics (CTT, CLDM, CZX, PLB, CTM) and our intensive care which succeed to control the gas producing infection, the patient died of suffocation on 46 days after admission.

Two cases of gas gangrene in the maxillofacial region and neck that developed after odontogenic infection are reported. Case 1, a 35-year-old man, developed gas gangrene after removal of the mandibular right third molar. In case 2, a 61-year-old man, gas gangrene occurred after apical periodontitis of the mandibular right second premolar. Both cases were treated by digitally opening the site where computed tomography (CT) revealed extension of gas bubbles early after the onset of symptoms and surgical debridement with antibiotics. CT was useful in monitoring the location of gas bubbles to permit opening of the progressive large focus in multiple spaces of maxillofacial region and neck. Digital preparation of the fascia was useful for opening the focus in the early stage of the disease.

This paper describes the incidence of complications following the surgical removal of impacted third molars in our department.Also dry soket, which had a highest incidence, were investigated for causal factors; skill of operator, age or sex of the patient.Results:1. The complication was found in 8.89% of 574 surgical removals. The incidence of dry socket was 5.57%, delay in healing was 1. 57%, postoperative infection was 0.87%, postoperative nerve paralysis was 0.35%, postoperative bleeding was 0.17% and other complication was 0.35%.2. The incidence of dry socket was 0.68% in the young patient group (under 20), 6.60% in the middle group (20-29) and 8.80% in the high age group (30-).The differences between in the young patient group and other patient groups were highly significant.These data suggested that age of the patient is one of the etiological factor of dry socket.

Primary carcinoma arising in the dorsum of the tongue is very rare and may be erroneously diagnosed as a benign lesion.<BR>We present a case of squamous cell carcinoma of the dorsum of the tongue in a 49-year-old man. Intraoral examination revealed a tumor measuring 41×30×7 mm in the midline of the dorsum of the tongue. A biopsy was performed, and the diagnosis was squamous cell carcinoma. After preoperative chemotherapy, total resection of the tumor was performed. During about 1 year of follow-up, there has been no sign of recurrence or metastasis.

Extraction of the lower third molars is a common procedure in oral surgery. After the procedure, disturbance of the lingual nerve is rare. In patients with mild injury, conservative treatment with drugs and stellate ganglion block may relieve symptoms. However, in severe cases, microsurgical treatment of the injured lingual nerve should be performed as soon as possible. We operated microsurgically in 3 patients with lingual nerve disorders that occurred after mandibular third molar extraction. After the operation, senses other than taste recovered in all patients, and taste was improved in 2 of the 3 patients. After the operation, 2 patients were satisfied, and the other was almost satisfied. No patient was dissatisfied. The concept for the management of such an iatrogenic lingual nerve injury remains unclear. In addition, we discuss treatment planning for iatrogenic lingual nerve injury

A case of pyostomatitis vegetans associated with ulcerative colitis is reported. A 57-year-old man with a history of ulcerative colitis was referred to our hospital because of pain in both sides of the buccal mucosa and malnutrition. A snail-track-shaped ulcer and miliary pustules with a cobblestone appearance were found in both sides of the buccal mucosa and soft palate. Treatment with topical corticosteroids had no effect on this lesion. The presence of abdominal pain and hematochezia led us to suspect a recurrence of ulcerative colitis. Immediately after the systemic administration of corticosteroids was started, the oral mucosal lesions resolved. This case suggests that treatment of ulcerative colitis with systemic corticosteroids is required to cure pyostomatitis vegetans.

Malignant tumors rarely arise from jaws cyst. We report a case of squamous cell carcinoma arising from a nasopalatine duct cyst. A 70-year-old man presented with a swelling in the palatal gingiva at the middle of the maxilla. Oral examination showed a 28×25mm swelling with a puncture mark, asmooth surface, and normal color. Radiographic examination revealed a round translucent image measuring 15×12mm in diameter in the middle of maxilla. The image was clearly demarcated. Under general anesthesia, extirpation of the cyst was performed for a diagnosis of nasopalatine canal cyst. Histopathological examination of the resected specimens showed transition of histologically normal cystic epithelium to squamous cell carcinoma. After the first operation, partial resection of the maxilla was performed. Three months after the partial resection, left jugular lymph node metastasis was detected. Partial neck dissection, chemotherapy, and irradiation were performed. Twelve months after partial resection of the maxilla, right jugular lymph node metastasis was found. Radical neck dissection was performed.For 2 years 4 months, there was no disease recurrence. However, the patient died due of pneumonia on April 13, 2002.

Photodynamic therapy is a new therapeutic technique that utilizes a photosensitizer selectively localized in tumors and activated by exposure to laser light, resulting in tumor necrosis. Photodynamic therapy has proved to be effective in the treatment of early cancers of the lung, esophagus, stomach, and uterine cervix, and was approved by the Japanese goverment. We consider early oral cancers to be good candidates for photodynamic therapy. This report describes two cases of tongue carcinoma treated by photodynamic therapy.

We describe a case of lacrimal sac fistulae with left cleft lip and palate. A congenital lacrimal sac fistula is a rare disorder in which a fistulous tract connects the skin to the common canaliculus or to the lacrimal sac, located just inferior to the medial canthal angle.A 12-year-old boy had 1) bilateral congenital lacrimal sac fistulae, 2) cleft lip and palate and 3) hypospadis. He had no paticular family history. With the patient under general anesthesia, a fusiform incision was performed, and the lacrimal sac fistulae were excised. Alveolar bone grafting was performed concurrently. Histologically, the lacrimal sac fistulae consisted of unkeratinized squamous epithelium and connective tissue with inflammatory lymphocytes. Patients with lacrimal sac fistulae, cleft lip and palate, and hypospadia have not been reported previously.These findings suggest that lacrimal sac fistulae may be related to congenital malfusions such as cleft lip and palate.
