[Prognosis of acute low-tone sensorineural hearing loss].
We studied 50 patients with acute low-tone sensorineural hearing loss (ALHL) who were examined at the Department of Otolaryngology, University of Tokyo, and followed up for 18 months or more. We investigated the prognosis of hearing loss within 3 months after onset, rate of recurrence during long-term follow-up, interval between the first and the second episodes of hearing loss or between onset...
متن کاملShort-Term Outcomes of Acute Low-Tone Sensorineural Hearing Loss According to Treatment Modality.
BACKGROUND AND OBJECTIVES We compared improvements in hearing thresholds in acute low-tone sensorineural hearing loss (ALHL) patients after two different treatments: steroid alone and steroid and diuretic combined. We analyzed how the duration between the onset of symptoms and the initiation of treatment affected hearing loss improvement and investigated the relation between presence of vertigo...
متن کاملStudying VEMP in Sudden Sensorineural Hearing Loss
Introduction: Sudden sensorineural hearing loss (SSNHL) has a prevalence of 10 in 100,000. Viral infections, vascular obstruction and rupture of the intracochlear membranes are supposed to be its most common etiologies. About 40% of patients experience vertigo or imbalance. The VEMP (vestibular evoked myogenic potentials) test is a known approach for detailed study of the labyrinth. The advant...
متن کاملPure-tone octave masking in listeners with sensorineural hearing loss.
Pure-tone octave masking was investigated in 14 listeners with sensorineural hearing loss to examine the hypothesis that the sensorineural ear introduces abnormal harmonic distortion. Thresholds for a test signal at f2, masked by a masking signal at fl, (where fz = 2fl ) were obtained as a function of the level of the fl masker for four different ft frequencies (250, 500, 1000, and 2000 Hz) and...
متن کاملComplex-Tone Pitch Discrimination in Listeners With Sensorineural Hearing Loss
Physiological studies have shown that noise-induced sensorineural hearing loss (SNHL) enhances the amplitude of envelope coding in auditory-nerve fibers. As pitch coding of unresolved complex tones is assumed to rely on temporal envelope coding mechanisms, this study investigated pitch-discrimination performance in listeners with SNHL. Pitch-discrimination thresholds were obtained for 14 normal...
