JOURNAL FREE ACCESSPostoperative oral function was analyzed in 27 patients with carcinoma of the tongue who underwent surgical operation including partial (16 cases), hemi-(8 cases), and subtotal (3 cases) glossectomy. Clinical examinations, including tongue movement, water swallowing test, repetitive saliva swallowing test, and swallowing pattern with video fluorography, were made prior to operation, and at 1, 3, 6, and 12 months post-operation. In the cases of patients with partial or hemi-glossectomy, the functional scores fell to the lowest 1 month after the operation, gradually increased from 3 months and reached a plateau at 12 months. Irrespective of the reconstruction methods, eventual outcomes of the function were influenced by the site and volume of the tissue removed, as shown by the fact that patients who underwent subtotal glossectomy had the worst scores of functional examination. This paper describes the clinical course of oral function recoveries, such as tongue movement, swallowing and others. We also discuss the validity of the various tests for oral functions we used in this study.View full abstractDownload PDF (1289K) -

JOURNAL FREE ACCESSThe purpose of this study was to evaluate the aspiration risk in dysphagia patients when eating cooked rice. The subjects were 36 patients with swallowing disorders. The risk of aspiration was examined with videofluorography. Test materials were four types of cooked rice: normal rice, soft rice, rice gruel and paste type. For the control, agar dissolved in water at a very low concentration was used because of its high sensitivity for diagnosing aspiration.
As a result, the dissolved agar was aspirated in seven patients and was penetrated in six patients and the rest showed no aspiration. The cooked rice, however, was not aspirated in any of the patients and only the paste type was penetrated in two patients. It seemed that the sample with liquid and pasty texture was hard to swallow, thus causing aspiration.
The results suggested that cooked rice except the paste type was safer for dysphagia patients. The texture of cooked rice had less effect on aspiration and penetration risk and mastication changed the speed of inflow to the pharynx.View full abstractDownload PDF (1069K) -

JOURNAL FREE ACCESSGlossodynia is characterized by a burning sensation in the tongue, usually in the absence of other abnormal findings. For that reason, it is one of the most common psychosomatic disorders in dental practice, and yet in many cases it is difficult to treat. It is therefore now thought to be associated with physical factors.
. We focused on disturbance of the blood flow of the tongue as a physical factor of glossodynia. The capsicum fruit has a pungent taste and produces a hot feeling throughout the oral cavity, occasionally causing pain. This pain, which is accompanied by a tingling burning sensation, is caused by capsaicin, the pungent active component of the capsicum fruit. Capsaicin sensitive sensory neurons respond to capsaicin. The terminals of these sensory neurons and their dorsal root ganglia contain transient receptor potential 1 (TRPV1). We hypothesized that TRPV1 plays an important role in the cause of glossodynia.
We compared the blood flow of patients with glossodynia with that of healthy controls using laser Doppler and thermography. The results showed greater blood flow in the healthy controls than in the patients with glossodynia.
In order to elucidate whether TRPV1 exists in the human tongue we used immunohistochemical staining and Western blot analysis. TRPV1 positive nerve fibers were recognized at various sites of the tongue mucosa, and in the taste buds as well. On Western blot analysis, a band was recognized around 95 kDa. Lafutidine is an H2-receptor antagonist that dilates blood vessels in the gastric submucosa and gastric mucosal tissue via TRPV1. We speculate that lafutidine may also be effective in glossodynia, because TRPV1 is also present in the tongue.
The improvement rate of pain after administration of lafutidine was 49.4% at 2 weeks and 78.7% at 8 weeks. Average VAS of pain was 48.1 mm before medication, and 16.1 mm 8 weeks after administration. Therefore, we conclude that lafutidine not only improves disturbance of blood flow but also blocks TRPV1 in the tongue. TRPV1 is currently receiving considerable attention for its potential role as a new target substance for the management of pain. Further studies of TRPV1 are necessary.View full abstractDownload PDF (3907K) -

JOURNAL FREE ACCESSA case of oral cancer showing cervical tuberculous lymphadenitis detected after neck dissection is presented. A 72-year-old female presented at our clinic complaining of oral pain. She had had a palatal pain for the previous five weeks. On clinical examination, a gingival ulcer was observed at the right palatal region and was diagnosed as squamous cell carcinoma by incisional biopsy. After neo-adjuvant chemotherapy, partial maxillectomy was conducted. One month after the resection, lymph node metastases in the right neck were detected by means of ultrasonography. Radical neck dissection was carried out immediately. Histopathological examination of the dissected specimen revealed two metastatic lymph nodes at level I & II and four tuberculous lymphadenitis at level V. Although there was a strong positive response to tuberculin antigen, radiographic and CT examination demonstrated no pulmonary lesions suspected of tuberculosis. PCR analysis of DNA and the Gaffky test showed negative results. The Ziehl-Neelsen staining of resected lymph nodes revealed no tubercule bacillus. Medication for tuberculosis was administered after consultation with the physician. The patient was followed up with no recurrence of tumor and no reactivation of tuberculosis for two and a half years after surgery.View full abstractDownload PDF (2229K) -

JOURNAL FREE ACCESSTrigeminal neuralgia is a disease commonly encountered in clinical practice, and has been ascribed to vascular compression of the trigeminal nerve root in the majority of cases. We report a rare case of trigeminal neuralgia apparently due to cerebral arteriovenous malformation (AVM). A 53-year-old male with a chief complaint of paroxysmal, electric shock-like pain on the right side of the face visited our department department.
Under a dignosis of trigeminal neuralgia, carbamazepine was administered resulting in relief of the pain. MRI showed AVM in the right middle temporal region with severe compression of the trigeminal nerve by a dilated tortuous left vertebral artery. Cerebral angiography revealed an AVM nidus, supplied by dilated temporal branches of the right posterior and middle cerebral arteries, as well as markedly dilated draining veins. These findings led to a diagnosis of trigeminal neuralgia due to AVM, and the patient has been followed in the Department of Neurosurgery.View full abstractDownload PDF (1591K) -

JOURNAL FREE ACCESSWe report a case of agenesis of the bilateral mandibular condyle. The patient was a 43-year-old male without any history of eventful delivery and trauma. His chin had been retruded since childhood. After extraction of the upper-right third molar in September 1998, he felt discomfort in his right cheek. He was referred to our hospital on March 23, 1999.
His height and weight were 170 cm and 60 kg, respectively. There was no evidence of Raynaud's phenomenon, and no abnormal finding on his skin and joints. No abnormalities were found on his eyes, eyelids, ears and hearing. The degree of mouth opening was 40 mm. The dental arch was parabolic with 10 mm of overjet and 2 mm of overbite, and the number of teeth was normal. Relatively good occlusion was observed in the molar region. Panoramic X-ray revealed the absence of mandibular condyle, short ramus and deep hollow on the mandibular plane in front of the mandibular angle. Lateral cephalogram demonstrated a small mandible and stricture of the airway. Though they were CT findings, the condylar head and articular disc on both sides were absent, and the base of the condylar process was positioned anteriorly to the glenoid process. Although the lateral pterigoid muscle ran to the inner surface of the mandibular ramus, there were no abnormal findings on zygoma, ear and mastication muscles. Laboratory data revealed no evidence of autoimmune disease such as rheumatism or scleroderma. This case was considered to be congenital absence of bilateral mandibular condyle, because the articular disc, which is thought to be developed from mesenchymal cells from which the condyle is also developed, could not be detected.View full abstractDownload PDF (2071K)
