JOURNAL FREE ACCESSA 42-year-old carpenter had been treated under a diagnosis of right otitis media with continuous headache symptoms at a local clinic. At about 4 weeks after onset, symptoms of nausea and dizziness developed. Both a right cerebellar abscess and a right middle ear cholesteatoma were identified by a brain CT scan and an MRI examination. Prior to performing tympanomastoid surgery for middle ear cholesteatoma, a resection of the cerebellar abscess was therefore urgently performed by neurosurgeons. After the tympanomastoid surgery, both the headache and dizziness continued but the hearing impairment improved. These findings demonstrate the importance of evaluating intracranial complication by CT or MRI when a patient complaints of continuous headache pain when receiving treatment for chronic otitis media, especially when cholesteatoma is observed.View full abstractDownload PDF (10054K) -

JOURNAL FREE ACCESSMyoepithelioma is an extremely rare tumor of the salivary glands and it accounts for less than 1% of all salivary gland tumors. In our department, we experienced 315 cases of salivary gland tumors over the past 10 years, but myoepitheliomas were only found in 2 cases. These two cases of myoepithelioma arising from the parotid gland are reported. Case 1 was a 57-year-old male who presented with a painless mass in the left parotid region. A surgical resection was performed and no adhesions of the tumor with the masseter and facial nerve were seen. Histopathologically, the tumor was composed of spindle-shaped cells and hyalinized stroma, and some tumor cells which ultrastructurally contained myofilaments. Another case was a 53-year-old female who was treated in the same manner as case 1. Sixty-eight cases of myoepithelioma of the salivary glands have been reported over the last 10 years in Japan. On the other hand, only 10 cases with a parotid origin have been reported. Histologically, myoepithelioma are classified into four types, and our two observed cases were both spindle cell type.View full abstractDownload PDF (14535K) -

JOURNAL FREE ACCESSTwenty-six cases (squamous cell carcinoma: 24, mucoepidermoid carcinoma: 1, undifferentiated carcinoma: 1) who were treated for cancers of the palatine tonsil between 1975 and 1998 are clinically reviewed. Advanced cases (stage III and IV) were found in 23 of 26 cases (88.5%). As a result, the 2-year crude survival rate of the early cases (stage I and II) was 100%. Regarding the advanced cases with either radiotherapy alone or radio chemotherapy, the 2-year crude survival rate was 40%. Regarding advanced cases combined with surgery and radiotherapy or chemotherapy, the 2-year crude survival rate was 66.7%. In the cases surviving more than 5 years after aggressive therapy (salvage operation or radiotherapy), 4 or 5 cases demonstrated either residual carcinoma or lymphnode recurrence. Fifteen of 22 patients who underwent radiotherapy showed CR. Six of 15 cases survived more than 5 years with CR. These CR cases were not related to the grades of T, N and/or histopathologic differentiation. The 3 cases who died (except for those with either therapeutic or operative mortality) and 1 recurrent surviving cases were all stage N, well differentiated cancers.View full abstractDownload PDF (10956K) -

JOURNAL FREE ACCESSA sixty-eight-year-old man with primary ethmoidal mucocele with an extension into the nasal cavity is described. A polyp-like lesion was found in the right nasal cavity, and a computed tomographic (CT) scan revealed the existence of a soft tissue mass filling the right anterior ethmoidal sinus. Endoscopic sinus surgery was carried out, and the polypoid lesion found in the nasal cavity proved to be an extension of the retention cyst in the right anterior ethmoidal sinus. The mucocele in the anterior ethmoidal sinus was subsequently opened widely up until the middle meatus. The literature on mucocele in the paranasal sinuses is also briefly reviewed.View full abstractDownload PDF (11419K) -

JOURNAL FREE ACCESSAfter, electrostimulation of the internal branch of the superior laryngeal nerve, the neuronal connection between the nucleus tractus solitarii (NTS) and the nucleus ambiguus (AMB) of the laryngeal reflex arc in the lower brainstem of the cat was investigated using the immunohistochemical double labeling method with cholera toxin in order to identify thyroarytenoid motoneurons, and Fos, the protein of the immediate early gene c-fos. Regarding the Fos expression, which is mainly observed in the NTS, both the reticular formation (RF) and the AMB, were counted under a microscope. The number of Fosimmunoreactive neurons was langer in the NTS than in the RF and the AMB, in that order. In the NTS, the number of Fos-reactive neurons on the stimulated side was significantly larger than that on the unstimulated side. These findings suggest that less than three inter neurons exist between the NTS and AMB in a reflective glottic closure with a latency of less than 9 msec after electric stimulation. From the NTS, the neuronal pathways of a direct connection to the bilateral AMB, the projections to the AMB via the contralateral NTS, and the neural connection to the AMB through the ipsi and contra lateral RF were all clearly demonstrated, and they might therefore also participate as several routes in the laryngeal reflex.View full abstractDownload PDF (22859K) -

JOURNAL FREE ACCESSWe performed an Issiki type III thyroplasty on a patient with mutational voice disorder and evaluated the acoustical differences between the pre and post-surgical voice. The results were that the fundamental frequency (Fo), shimmer parameter (SP), and normalized noise energy b (NNEb) decreased after the operation. Since this procedure was effective not only for lowering vocal pitch, but also for improving hoarseness, it might be a good choice for treatment of patients with mutational voice disorders, especially those with laryngeal noise.View full abstractDownload PDF (8065K) -

JOURNAL FREE ACCESSThe purpose of this preliminary study was to investigate which scale, a visual analog scale or a 4-point scale, is useful to evaluate the changes between pre- and post-operative voices. The subjects are 20 voice samples of 10 patients who received laryngomicrosurgery. Two raters evaluated the voice on a visual analog scale and then on a 4-point scale four months later. 5 cases changed 14 points and more than on the visual analog scale, 4 of them showed the change on the 4-point scale. The changes on a visual analog scale between preand post-operative voices corresponded well with the changes in PPQ values except for 3 cases. In contrast, 4 patients did not show the changes in 4-point scale in spite of the value changes in PPQ. This result suggests that visual analog scale can represent the small change between pre- and post-operative voice rather than the 4-point scale.View full abstractDownload PDF (6143K) -

JOURNAL FREE ACCESSCicatrical pemphigoid is a rare autoimmune blistering disease with a chronic relapsing disease course. involving predominantly mucous membranes that often results in scar formation in elderly patients. We report an 81-year-old Japanese male patient with anti-epiligrin cicatrical pemphigoid, who showed a severe laryngeal stenosis which necessitated a tracheostomy. Later, cutaneous bullous lesions appeared on the whole body. Direct immunofluorescence showed deposition of IgG and C3 along the basement membrane zone. The diagnosis was made by the results of immunofluorescence and immunoprecipitation studies. He was treated with combination of tetracycline 1,500mg/day and nicotinamide 1,500mg/day, and skin lesions disappeared quickly. Because dyspnea disappeared in two months, the tracheal stoma was closed under local anesthesia. He showed no respiratory difficulty for 7 month follow-up period.View full abstractDownload PDF (14865K) -

JOURNAL FREE ACCESSIn this paper, we report two cases with glottal obstruction following total thyroidectomy, who were successfully treated with thyroplasty type IV. They had received tracheostomy for a management of dyspnea immediately after the thyroidectomy. Dyspnea had persisted against several kinds of surgical intervention to widen glottal space or conservative treatment. Endoscopic observation showed bilateral false vocal folds bulging and glottal shortening in anteroposterior direction with paralysis of the vocal folds. Bilateral cricothyroid muscle dysfunction was thought to be a main cause of these findings. Therefore, thyroplasty type IV by Isshiki was performed in combination with unilateral arytenoidectomy in one case and partial resection of the false vocal folds using CO2 laser in the other. After the procedures, sufficient glottal space was obtained, and tracheostoma was successfully closed in both cases.View full abstractDownload PDF (10152K) -

JOURNAL FREE ACCESSGlottal incompetence is a serious problem after the extended frontolateral laryngectomy performed for a T2 or T3 glottic carcinoma. To form a protrusion at the level of the vocal fold, we reconstructed the glottis using a folded skin flap with the peripheral half denuded. This surgery was performed for two patients; one with T2 glottic carcinoma and another with recurrent (r) T3 glottic carcinoma after radiation therapy. In both cases, the protrusion of the reconstructed vocal fold has been maintained for more than five months after surgery. The T2 case had almost normal voice and phonatory function. In the rT3 case, the voice was hoarse, but the phonatory function was satisfactory.View full abstractDownload PDF (8667K) -

JOURNAL FREE ACCESSVoice disorders have been regarded as one of the major symptoms of GERD. We made a clinical study of voice disorders in 135 cases who diagnosed as GERD based on pharyngolaryngeal and esophageal findings. Out of the 135 cases, 45 cases complained of voice problems on a questionnaire survey before PPI treatment. Perceptual evaluaion using GRBAS rating scale showed that 18 cases out of the 45 had some degree of hoarseness. Laryngeal examination revealed different types of organic change in 20 of the 45 cases, including granuloma in 7, corditis in 4, sulcus vocalis in 4, polypoid vocal cord in 3 and vocal cord polyp in 2. After the administration of PPI for 8 weeks, subjective voice complains improved in 19 cases(40%). On the other hand, hoarseness improved in 2 cases out of the 18 cases in perceptual evaluation after the treatment. As for laryngeal findings, corditis improved in all 4 cases and granuloma improved in 4 out of the 7. It was considered that PPI treatment was effective for voice disorders in cases in which GERD was suspected by clinical examinations.View full abstractDownload PDF (8913K) -
