摘要:

Tinnitus has been reported with use of piroxicam (Feldene) a nonsteroidal anti-inflammatory drug. Two cases of temporary hearing loss have also been reported. To the best of our knowledge the patient reported herein represents the first case of permanent hearing loss and tinnitus associated with use of the drug.

摘要:

Bilateral facial paralysis is a rare disorder, and its work-up should include a complete neurotologic assessment plus neurologic consultation and lumbar puncture. The various causes and their treatment are discussed and the treatment of longstanding facial paralysis is reviewed.

摘要:

The California Consonant Test (CCT) was used to evaluate different hearing aids for twelve listeners with mild to moderate sensorineural hearing losses. The CCT was mixed with white noise at signal-to-noise ratios (S/Ns) of +30 (quiet), +15, +5, and 0 dB and presented through hearing aids for each listener; the quiet condition was retested. Significant differences were found between mean test scores for the high and low S/Ns. Intralistener hearing aid differences were found most frequently in the quiet condition. Truncation errors were frequent for the low S/Ns. These findings indicate that the sensitivity of the CCT is decreased rather than increased by mixing it with noise. Critical differences of 5% or more between hearing aids were more frequent as the S/N improved; the greatest number of differences occurred for the quiet condition.

摘要:

The effect of premedication with morphine and anticholinergic dugs on absolute and interpeak latencies of brain stem auditory evoked potentials was studied in thirty patients. Two commonly used anticholinergics, glycopyrrolate and scopolamine, given in combination with morphine were studied. Patients premedicated with morphine alone served as a control group. No significant change in either absolute or interpeak latencies was noted in patients premedicated with either morphine alone or morphine and glycopyrrolate. Results in patients premedicated with morphine and scopolamine are inconclusive because of large intersubject variability.

摘要:

The likelihood that a single mechanism of immune injury is the sole cause of serous otitis media is quite small. Solid evidence is presented to suggest that type I and III immune injuires are very important, and type IV may also play a role in causing and potentiating serous otitis media in man.

摘要:

We present a case report of a woman with adenocarcinoma of the breast and metastasis to the temporal bone. The diagnosis of metastasis to the temporal bone may be difficult to make, for the symptoms and findings may mimic those of chronic infection. A high-resolution computed tomography scan is mandatory for complete investigation.

摘要:

We examined the effectiveness of sodium fluoride in treatment of cochlear otospongiosis in ninety-four patients with cochlear otosclerosis and ninety-eight patients with stapedial otosclerosis and sensorineural hearing loss. The drug halted or slowed the progression of sensorineural hearing impairment in 63% of the patients with cochlear otosclerosis and 46% of the patients with stapedial otosclerosis. The single factor that best predicted which patients would respond most favorably to treatment was rate of progression before treatment. Sodium fluoride therapy was successful for 79% of the patients losing their hearing at a rate of 5 dB or more per year at one or more of the speech frequencies. The finding that patients with more rapid rates of progression responded most favorably to sodium fluoride therapy suggests that patients with the most active otospongiotic processes will be the most responsive to treatment.

摘要:

External ear canal cholesteatoma (EECC) is a rare otologic entity. Erosion of the inferior canal wall and accumulation of keratin debris are consistent findings. In the past there had been confusion between EECC and keratosis obturans, and they were thought to represent the same disease process. Currently, based on clinical and pathologic findings, it is believed that they are two different entities. In this article we present our experience in treating eight patients with EECC. For limited lesions, local debridement and curettage of necrotic bone is effective management. For more extensive lesions, canalplasty or tympanomastoidectomy is indicated.

摘要:

Histologic and histochemical studies of the endolymphatic sac of full-term rat fetuses were undertaken to clarify the anatomy of the endolymphatic sac, and the mechanism of endolymph circulation and regulation. Hitherto undescribed structure enveloping the sac with blood vessels extending from the sigmoid sinus resembling the kidney glomerulus was seen. This endolymphatic “glomerulus” is believed to provide a means of active exchange of water and electrolytes between blood vessels and the endolymphatic sac.
