ジャーナル フリーThe purpose of this study was to analyze the prevalence of and risk factors for contralateral cervical lymph node metastasis (CLNM) from squamous cell carcinoma arising in the mobile part of the tongue.
Retrospective reviews of the tumor patient registry between 1985and 1999 revealed 84 patients with newly diagnosed carcinoma of the mobile part of the tongue that had been controlled by initial treatment. Thirteen of these patients (15.5%) had CLNM. On stepwise logistic regression analysis, T-stage, histopathological grade, and level of ipsilateral cervical lymph node metastasis were found to be significant predictors of CLNM. Our results suggest that CLNM is unlikely in patients with T 1 tongue cancer or no involvement of ipsilateral lymph nodes. It was also suggested that we should pay careful attention to CLNM in patients with advancing T-stage, histopathological grade, or level of ipsilateral lymph node metastasis.抄録全体を表示PDF形式でダウンロード (702K) -

ジャーナル フリーPrimary liposarcoma is extremely rare in the oral cavity and usually involves the thigh, retroperitoneum, or inguinal region. We describe a 45-year-old man who presented with a soft painless mass measuring 18×15×15mm in the right margin of the tongue. MR images demonstrated a well-defined solitary mass in the right margin of the tongue. T 1-weighted MR imaging showed low signal intensity. T 2-weighted MR imaging and fat-suppressed T 2-weighted MR imaging showed homogenous and high signal intensity. The pathological diagnosis of a frozen section specimen was myxoma or myxofibroma. The tumor was considered benignand resected with the patient under general anesthesia. However, the final pathological diagnosis of the tumor was liposarcoma, myxoid type, according to the WHO classification of 1969. Onemonth later, we performed an additional glossectomy as recommended by our pathologist. There were no signs of recurrence at 3-year follow-up.抄録全体を表示PDF形式でダウンロード (1820K) -

ジャーナル フリーWe report a rare case of chondrosarcoma occurring in the incisal region of the mandible ina 42-year-old man. This tumor produces a cartilaginous matrix and occurs rarely. It accounts for approximately 0.2% of all malignant tumors in the oral and maxillofacial region. The lower incisal region is a very rare site of occurrence. Although the criteria for histologic diagnosis proposed by Lichtenstein are clear-cut, it is often difficult to make a final diagnosis on the basis of small specimens. Our patient presented with a painless swelling at the lower incisal region of the mandible. Biopsy initially suggested a chondroid tumor, and the lesion was excised with the patient under general anesthesia. Histopathologicand radiographic examinations of the excised lesion resulted in a final diagnosis of chondrosarcoma. A bone scintigram obtained after the operation showed no abnormal accumulation of 99mTc. There has been no sign of recurrence or metastasis as of 4 years afterthe operation.抄録全体を表示PDF形式でダウンロード (2429K) -

ジャーナル フリーA 29-year-old woman was referred to our clinic on August 8' 2001 because of a mass along the posteroinferior aspect of the left parotid gland. Clinical examination revealed a welldemarcated painless mass, measuring about 3×2 cm. Computed tomographic examination showed a well circumscribed mass. On magnetic resonance imaging, T 2 -weighted images of themass showed high signal intensity. A clinical diagnosis of a benign parotid gland tumor was made, and a superior parotidectomy was performed with the patient under general anesthesia. There was no evidence of invasion to facial nerves. Pathologically, the mass was diagnosed as myoepithelioma (plasmacytoid cell type). Immunohistochemically, S-100 protein, vimentin, and glial fibrillary acidic protein were detected in the tumor cells. The postoperative course was uneventful. There was no evidence of recurrence lyear 10 months after the operation.抄録全体を表示PDF形式でダウンロード (2734K) -

ジャーナル フリーA rare case of eosinophilic granuloma of the mandibular condyle in a 53-year-old woman is presented. The patient was referred to our department because of pain following discomfortin the left preauricular region. She had limitation of mouth opening without swelling or noise in the temporomandibular joint region. A panoramic radiograph showed an ill-defined lytic lesion occupying the left condyle. On MR imaging, the lesion was depicted as low signal intensity on T 1 -weighted images and as high signal intensity on T 2-weighted images and involved the condyle and lateral pterygoid muscle. The excised specimen obtained from the condyle was histologically diagnosed as eosinophilic granuloma. Mouth opening difficulty and pain resolved postoperatively. The condyle was regenerated 1 year after surgery, andthere has been no evidence of recurrence for 3 years 10 months.抄録全体を表示PDF形式でダウンロード (2574K) -

ジャーナル フリーArteriovenous malformation (AVM) rarely occurs in the head and neck region. AVM of the masseter muscle is extremely rare. We report a case of AVM of the masseter muscle. The patient was a 54-year-old woman with pain of the left masseter muscle region for about 1 week. She had a movable mass in the left masseter region. On clenching, the mass became erect. Enhanced CT scanning showed a high density region in the masseter muscle. MRI T 1 imaging showed that the tumor was the same signal intensity as muscle. On MRI T 2 images, signal intensity of the mass was greater than that of fat. Color Doppler imaging showed high intensity color flow at the base of the mass. Under the diagnosis of an erectile hemangioma of the masseter muscle, the mass was resected surgically with an Nd: YAG laser via submandibular and preauricular approaches on May 17, 2000. Hemorrhage (20 grams) was controlled by ligation of the feeding artery. Histologically, the mass consisted mainly of cavernous hemangiomatous proliferation of veins with arterialisation and a few structurally deformed arteries. The pathological diagnosis was arteriovenous malformation. The postoperative course was without complications. As of 29 months after operation, there has been no sign of recurrence.抄録全体を表示PDF形式でダウンロード (2828K) -

ジャーナル フリーThe speech function of a 55-year-old woman with a speech disorder due to a large torus palatinus was evaluated before and after surgery. Auditive impressions were assessed by a speech intelligibility test of 100 syllables, an articulation test, and a diadochokinetic ability test. Speech functions were measured by static palatography, tongue cephalography with contrast media, and acoustic analysis. The results showed slight speech disorder during production of /hj/, /kj/, and /gj/ before surgery and improvement in speech function without speech therapy after surgery.抄録全体を表示PDF形式でダウンロード (2341K) -

ジャーナル フリーIntracranial perfusion failure is one of the well-documented complications of bilateral radical neck dissection, but rarely occurs after unilateral radical neck dissection. We describe a male patient who had intracranial perfusion failure after unilateral radical dissection of the right side of the neck. Three days after the dissection, he complained of severe headache and nausea and then had increased blood and intracranial pressures. Carotid angiograms showed dominant right transverse sinus drainage probably because of hypoplastic left transverse sinus drainage. Furthermore, dissection of the right internal jugular vein caused occlusion at the superior bulb of the right jugular vein, leading to intracranial perfusion failure. The patient was treated by drainage of cerebrospinal fluid and a dehydrator and became asymptomatic. In our patient radical neck dissection done on the side of the dominant transverse sinus drainage, caused intracranial perfusion failure followed by severe headache and nausea, possibly because of the hypoplastic contralateral transverse sinus drainage.抄録全体を表示PDF形式でダウンロード (2595K) -

ジャーナル フリーWe report a median maxillary cyst containing many foreign bodies, which were analyzed by Raman spectroscopy.
A 64-year-old man was referred to our hospital by his dentist for further evaluation. Radiographic examination revealed a cystic lesion of an upper incisor, containing many radiopaque masses. The clinical diagnosis was a calcifying odontogenic cyst.
The cyst was removed with the patient under general anesthesia, and histopathologicaldiagnosis of the residual cysts was done. The cyst contained many unknown foreign bodies.
To determine the nature of the foreign bodies, Raman spectroscopic analysis was carriedout. Raman spectra of the foreign bodies were very similar to those of polymethyl metacrylate (PMMA) or silicone materials. These dental materials were possibly impacted into the cyst during dental treatment. Raman spectroscopic analysis was considered very useful for evaluating foreign bodies in the oral and maxillofacial region.抄録全体を表示PDF形式でダウンロード (1564K) -

ジャーナル フリーPolycythemia vera (PV) is a hematopoietic stem cell disorder that results in an increased total red cell volume. Clinically, polycythemia vera is usually diagnosed after hematologic complications, such as major thrombosis or hemorrhage. Because invasive dental treatmentfor patients with PV can cause uncontrolled hemorrhage or thrombosis, including disseminated intravascular coagulation (DIC), careful preoperative assessment and treatment planningare needed. We report a case of multiple tooth extraction in a patient with PV. A 55-year-old man with PV was referred to our clinic because of abnormal bleeding after periodontal scaling. He had a history of multiple cerebral infarction and hypertension, and had beenreceiving an oral antithrombotic drug. Since the patient complained of difficulty in eating due to gingival bleeding associated with severe periodontitis, tooth extraction was planned. The blood condition was controlled by the patient's physician and multiple tooth extraction was performed without stopping the oral antithrombotic drug. Although hemorrhage fromthe socket recurred for several days, complete hemostasis was achieved 10 days after surgery by the use of a hemostatic splint.抄録全体を表示PDF形式でダウンロード (1497K) -

ジャーナル フリーTwo cases of excessive muscle contraction in the oro-facial area that were treated by intramuscular injection of botulinum toxin (BTX) are reported.
Patient 1, a 68-year-old woman with a diagnosis of tongue carcinoma, had idiopathic hemifacial spasms. She received local injections of BTX type A (10 to 20U) into facial muscles 3 times. Consequently, facialspasms improved considerably. Electromyography showed reduced muscle fibrillation on blinking.
Patient 2 was a 44-year-old man who had speech disturbance because of involuntary overactive muscles of the mouth region. He received local injections of BTX type A into the lower facial muscles 3 times for a diagnosis of facial spasm and oromandibular dystonia.The dose of BTX ranged from 10 to 30 U. Oral movement disorder improved. The patient's speech is now very smooth and clear.
These two patinets had no disabling side effects. Botulinum therapy seems to be effective in carefully selected patients with overcontraction of oro-facial muscles.抄録全体を表示PDF形式でダウンロード (2263K) -

ジャーナル フリーWe clinically observed patients treated between January 1999 and December 2001 at the department of oral and maxillofacial surgery after being brought by ambulance to a city emergency hospital. Of 11, 105 patients who were brought by ambulance during that period, 308 (2.8%) underwent oral or maxillofacial surgery. The male: female ratio was 2.1: 1, and more than half of the patients were younger than 30 years. There were 2 peaks in the age distribution: 2 and 21 years of age. Eighty-seven percent of the patients had traumasta such as lacerated wounds of soft tissue, alveolar bone fractures, and tooth luxation. Twenty-five of these patients (8.1%) required treatment under general anesthesia. Two patients with severe odontogenic infections underwent emergency surgery.
Several of the patients who were brought to the hospital by ambulance required specialized oral and maxillofacial treatment.抄録全体を表示PDF形式でダウンロード (623K)
