ジャーナル フリーRemoval of mandibular third molars is one of the most common operations in oral surgery. Hypoesthesia of the lower lip occurring after the extraction of third molars is a serious complication, requiring a prolonged time for recovery. In this study, we investigated factors potentially affecting the incidence of hypoesthesia.
A total of 781 mandibular third molars extracted at our clinic in 2002 were examined. There were 17 cases (2.2%) of hypoesthesia of the lower lip. There was no relation of gender, difficulty of extraction, or the skill of the operator to the incidence of hypoesthesia. In contrast, the incidence of hypoesthesia strongly correlated with age and the root position of mandibular third molars with respect to the mandibular canal.
Eleven of the 17 cases of hypoesthesia (64.7%) resolved within 1 month, and 16 of the 17 cases (94.1%) resolved within 6 months. The patients who had hypoesthesia for more than 1 monthwere significantly older than those who recovered from hypoesthesia within 1 month and were all female.
These results might be useful when informing patients about potential complications of tooth extraction.抄録全体を表示PDF形式でダウンロード (1000K) -

ジャーナル フリーMotor vehicle accidents (MVAs) are the leading cause of oral and maxillofacial injuries. We retrospectively analyzed the severity of oral and maxillofacial injuries caused by MVAs.
Hospital records were reviewed for all patients who had sustained oral or maxillofacial injuries in MVAs and been admitted to the Department of Oral and Maxillofacial Surgery, Dokkyo University School of Medicine, from 1994 through 2003.
A total of 105 patients, with a mean injury severity score (ISS) of 9.2±9.0, were studied. Age ranged from 1 to 89 years, with a mean age of 29.0±15.3 years. Although patients with oral or maxillofacial injuries had extremely low ISSs, hospitalization was relatively long. Furthermore, the longer the duration of hospitalization, the higher was the maximum abbreviated injury scale (AIS) score of the patients. The ISS and AIS scores were compared between patients brought to the hospital by ambulance and those coming by other means.
The ISS and AIS scores of the chest and extremities were significantly higher in the ambulance group (11.1±9.6, 0.8±1.4, 1.1±1.2, respectively) than in others (7.0±7.8, 0.1±0.6, 0.7±0.8, respectively, p<0.05). However, the AIS scores of the face were similar in these two groups (1.9±0.6 vs. 1.7±0.6). Furthermore, the incidences and severities of oral and maxillofacial injuries were compared between with and without the use of seat belts. The incidences of maxillofacial injuries and the AIS score of the face did not differ significantly between the two groups. Because wearing seat belts cannot prevent all oral and maxillofacial injuries caused by MVAs, both dentists and oral surgeons must pay greater attention to the mechanisms of such oral and maxillofacial injuries.抄録全体を表示PDF形式でダウンロード (1015K) -

ジャーナル フリーDiffuse sclerosing osteomyelitis (DSO) of the mandible is a relatively uncommon, non-suppurative, chronic inflammation of obscure etiology. Various treatments have been reported, but long-term results remain unsatisfactory. We describe a patient who remarkably responded to hyperbaric oxygen therapy (HBO) in conjunction with conservative surgery (saucerisation and trepanation). Serial panoramic radiography, computed tomography, and magnetic resonance imaging (MRI) were employed to assess the healing progress. Follow-up MRI was the most sensitive technique for evaluating restoration of bone marrow vascularization. This study presents objective evidence of the success of our treatment, evaluated on the basis of images obtained over a 3-year follow-up period.抄録全体を表示PDF形式でダウンロード (2395K) -

ジャーナル フリーWe describe a case of fibrous granuloma containing a heavy-metal tungsten alloy. The patient was a 58-year-old man who had a mass in his left cheek. The mass was hard and 2 cm in diameter, without tenderness. Radiography revealed a radiopaque shadow suggesting a metal object. Although the patient had sudden bleeding of his left cheek while using an electric sickle 3 years ago, he felt no pain and received no medical treatment.
A black metal foreign body, 2 mm in diameter, was found in the center of the surgically removed tumor mass. No pigmentation surrounded the foreign body. The metal was tungsten-cobalt on X-ray analysis.抄録全体を表示PDF形式でダウンロード (2255K) -

ジャーナル フリーA patient with a large odontogenic myxoma of the maxilla is described. A 13-year-old boy was referred to our hospital because of a swelling in the maxilla. Radiographic and computed tomographic examinations showed a well-demarcated tumor in the maxillary sinus that contained small calculi and was associated with extensive resorption of maxillary bone. Histological examination revealed that the tumor consisted of spindle-shaped cells with no atypia in the myxomatous connective tissue. Scattered cement-like small calculi were present. An odontogenic myxoma was diagnosed. The tumor was extirpated by an intraoral approach. There has been no evidence of recurrence 18 months after surgery.抄録全体を表示PDF形式でダウンロード (2607K) -

ジャーナル フリーBasaloid squamous cell carcinoma was first reported by Wain et al. in 1986 and has recently been designated a variant of squamous cell carcinoma because of its high potential for distant metastasis. We report a case of basaloid squamous cell carcinoma arising in the floor of the mouth in a 74-year-old man. The proliferative activities of this case and another case previously reported by our department were compared with those of 21 cases of poorly differentiated squamous cell carcinoma. The cases of basaloid squamous cell carcinoma showed high reactivity on Ki-67 immunohistochemical staining. This finding reflects the high malignancy of this disease and suggests that Ki-67 immunohistochemical staining is useful for diagnosis. Radiotherapy was very effective against the primary lesion in our two cases, but both had lung metastasis. In our patient, lung lesions were controlled by chemotherapy, but further investigations are needed to establish standard treatment, including systemic chemotherapy.抄録全体を表示PDF形式でダウンロード (1661K) -

ジャーナル フリーRanula is a mucous cyst arising in the floor of the mouth. It is very rare in newborn babies. We report a case of congenital ranula.
The patient was a 4-month-old boy who had a swelling in the floor of the mouth since birth. The lesion floor did not disappear by, 4 months of age, and he was referred to the Department of Dentistry and Oral Surgery, Keio University Hospital by a pediatrician. Magnetic resonance imaging confirmed the presence of a cystic lesion in the floor of the mouth, measuring30×25mm.The lesion was diagnosed to be a sublingual ranula.At the age of 7 months, marsupialization of the cyst was performed with the patient under general anesthesia.
There has been no recurrence about 1 year 3 months after operation.抄録全体を表示PDF形式でダウンロード (2260K) -

ジャーナル フリーFibromyalgia syndrome is a disease characterized by chronic pain and multiple tender points over the entire body. The cause of the disease is unknown, and patients are sometimes have various uncertain complaints. In this paper, we report a case of temporomandibular disorders (TMD) accompanied by fibromyalgia.
The patient was a 26-year-old woman who received treatments for autonomic imbalance and panic disorder at a psychosomatic clinic. She complained of strong malaise, headache, tinnitus, insomnia, and constipation. She also had bilateral pain of the masticatory and neck muscles and around the temporomandibular joints. The range of maximum mouth opening was 23mm. The patient had edge-to-edge occlusion in the molar region and slight open bite in the incisor region.
She received a diagnosis of temporomandibular disorders of type I and fibromyalgia. The patient was successfully treated with a stabilization splint for temporomandibular disorders and antidepressants for fibromyalgia.抄録全体を表示PDF形式でダウンロード (2491K) -

ジャーナル フリーAfter the surgical treatment of oral cancer, large orocutaneous defects developing in a contaminated or irradiated area are usually complicated and require operations for reconstruction. At our department, a pediculate regional flap has been often used to repair orocutaneous defects. However, from the viewpoint of preservation and restoration of oral cavity function and structure and the extent of the resulting defects, the repair of orocutaneous defects remains an unsolved problem.
We describe a large orocutaneous defect associated with osteoradionecrosis that developed after excision of a tumor arising in the floor of the mouth. The large defect was reconstructed by combining a free omental graft with a delto-pectoral flap (D-P flap). The function and structure of the oral cavity was thereby preserved.
Five years two months postoperatively, neither development of a new fistula nor osteoradionecrosis was observed. Our results suggest that a free omental graft is a useful method that should be considered for the repair of full-thickness defects in patients with oral cancer to ensure a better quality of life.抄録全体を表示PDF形式でダウンロード (2776K) -

ジャーナル フリーWe studied soft tissue injuries of the oral cavity caused by a toothbrush in 59 children younger than 7 years from 1983 through 2003. There were 35 boys and 24 girls aged 9 months to 6 years 7 months, with a peak incidence at 1 year. Falling down was the cause of injuries in 46 children. Forty-one children visited us directly, whereas others were referred to us by surgeons, emergency specialists, dentists, otolaryngologists, and others. Thirty-one children presented within 3 hours after injury and 15 the following day. The soft palate and palatoglossal arch, buccal mucosa, hard palate, oral floor, retromolar region, upper lip, gingiva, and tongue were involved in 25, 20, 6, 3, 2, 1, 1 and 1 child, respectively. Lacerations greater and less than 10 mm long were seen in 20 and 16 hildren, respectively. Submucous bleeding was present in 13 children, and scratches were present in 10 children. In 3 children, the wound was associated with herniation of the buccal fat pad. The wound was sutured and antibiotics were given to 23 children. Twenty children were observed without antibiotic treatment, and 16 children were given antibiotics. Local infection occurred in 3 children.抄録全体を表示PDF形式でダウンロード (1700K) -
