JOURNAL FREE ACCESSWe retrospectively evaluated the efficacy of combination therapy with steroid and hyperbaric oxygenation for sudden idiopathic sensorineural hearing loss (SISNHL). Patients (n : 109 ; 111 ears) visited our clinic within 14 days from onset before receiving treatment between January 1999 and March 2003. Hearing loss was assessed based on criteria prepared by the Ministry of Health and Welfare Acute Severe Hearing Loss Study Group. Patients were distributed into Group I-95 patients who started treatment within 7 days from onset-, and Group II-14 patients who started treatment within 8-14 days from onset. We evaluated the outcome of therapy using grading established by The Research Committee on Acute Profound Deafness, Ministry of Health and Welfare, Japan. The complete recovery of hearing was worse in patients with severe hearing loss. It was 4.8% in grade 4a, 18.2% in grade 3a, 25% in grade 2a, 20.0% in grade 4b, 38.5% in grade 3b, and 66.7% in grade 2b. We studied the relationship between type of hearing loss and recovery after treatment. The complete recovery of hearing was most favorable in patients with low tone hearing loss, followed by those with middle tone hearing loss and those with horizontal hearing loss. These findings indicate that the type of hearing loss was the most significant determinant of SISNHL prognosis and course. Twenty patients with acute stage SISNHL had diabetes mellitus. The recovery of hearing was almost the same in those with and without diabetes mellitus. Recovery was complete in 32.4%, marked in 32.4%, and slight in 21.6%. In 13.5%, no change was observed. Our results and data from previous reports, involving more than 70 Japanese patients treated with steroids alone, suggest that combination therapy with steroid and hyperbaric oxygenation is effective for SISNHL.View full abstractDownload PDF (2358K) -

JOURNAL FREE ACCESSThe middle ear is a rare site for benign tumors. We report six patients with benign middle ear tumors surgicaly removed : three with carcinoid, one with adenoma, and two with paraganglioma. These tumors showed similar histological features in trabecular and glandular architecture, so further immunohistochemical study was needed to make a definitive histopathological diagnosis. When we analyzed clinical features of patients diagnosed immunohistochemically, the differentiation of two patients with paraganglioma from the remaining four with adenomatous tumors such as adenoma and carcinoid was relatively easy from otomicroscopic findings and enhancement in temporal bone MRI. It was however difficult to differentiate patients with adenomatous tumors from each other because they induced similar clinical symptoms and showed similar findings in images. For a definitive diagnosis, it is necessary to conduct exploratory tympanotomy or removal of the tumors to obtain enough specimen for histological and immunohistochemical studies. Tumors induced no bone destruction or complications. We recommend staged operations for total removal of tumors and for good postoperative hearing.View full abstractDownload PDF (3570K) -

JOURNAL FREE ACCESSWe report results of a retrospective study of 12 cases of adenoid cystic carcinoma (ACC) in the parotid gland. Local pain was often observed in ACC among other malignant parotid tumors. Although fine-needle aspiration cytology (FNA) was not effective for preoperative diagnosis, frozen section diagnosis (FS) during surgery showed excellent results.
Cases with T3 or T4 underwent total or enlarged parotidectomy, but, often showed positive surgical margins. Postoperative radiation therapy seemed useful in these cases and the 5-and 10-year disease-specific survivals in these 12 cases were 90.0% and 80.8%. These compare favorably with other reports in the literature. All 12 cases showed N0 and no cervical relapse with or without neck dissection, indicating little effectiveness in prophylactic neck dissection.
Tumor size, positive surgical margins, and perineural invasion are risk factors for this tumor as mention previously. Patients with perineural invasion, especially preoperative facial nerve palsy (T4a), are more likely to fail than those with two other factors, so, it seems conceivable for cases of T4a to undergo more positive treatment with surgery and postoperative radiation.View full abstractDownload PDF (507K) -

JOURNAL FREE ACCESSWe report 3 cases of muscle tension dysphonia (MTD), all involving women 44 to 68 years old, recovered using proton pump inhibitors (PPI). Case 1 had open posterior commissure (MTD Type I) and Cases 2 and 3 supraglottis compression (MTD Type II, III). It is generally assumed that functional dysphonia with maladjustment of laryngeal muscle tension is caused by improper phonation and/or emotional disorder. Our cases, however, suggest that laryngopharyngeal reflux (LPR) may also relate to the occurrence of MTD.View full abstractDownload PDF (1302K)
