The present study examined the effects of steep high-frequency sensorineural hearing loss (SHF-SNHL) on speech recognition using acoustic temporal fine structure (TFS) in the low-frequency region where the absolute thresholds appeared to be normal. In total, 28 participants with SHF-SNHL were assigned to 3 groups according to the cut-off frequency (1, 2, and 4 kHz, respectively) of their pure-t...

Over the last decade, a number of distinct mutations in the mtDNA (mitochondrial DNA) have been found to be associated with both syndromic and non-syndromic forms of hearing impairment. Their real incidence as a cause of deafness is poorly understood and generally underestimated. Among the known mtDNA mutations, the A1555G mutation in the 12S gene has been identified to be one of the most commo...

Hearing loss is the most common sensory deficit in the elderly, and is becoming a severe social and health problem. Presbycusis is the result of aging which can lead to communication problems compromising the quality of life (QoL).Since the elderly population is increasing worldwide, presbycusis is showing a similar trend. This study intended to identify the impact of hearing loss in the social...

OBJECTIVE We evaluated the causes of hearing loss found after failed universal newborn hearing screening and compared the results with the previously used behavioral observation test (Ewing/CAPAS). STUDY DESIGN Hearing loss in neonates, born between September 1999 and October 2007 and referred to our center after failed screening, was determined by audiologic testing and physical examination....

Objective To assess long-term hearing outcomes in patients treated with third-generation bisphosphonates for otosclerosis-related progressive sensorineural hearing loss (SNHL). Study Design Retrospective case series review. Methods We performed a retrospective case series review of patients with otosclerosis and progressive SNHL. Patients were treated with either risedronate or zoledronate ...

OBJECTIVES 1) Characterize the current presentation of pediatric temporal bone fractures, 2) compare two classification schemes for temporal bone fractures and illustrate complications in each fracture type. DESIGN Retrospective medical record review. SETTING Tertiary-care, academic children's hospital. PATIENTS All children presenting from 1999 to 2009 with CT-proven temporal bone fractu...

Arecent review made note of the 50th anniversary of the identification of human cytomegalovirus (CMV) in cell culture, an important milestone that paved the way to today’s understanding of the molecular biology, immunology, and clinical importance of this ubiquitous viral infection. In the past 50 years, much progress has been made in the characterization of disease caused by CMV. Solid organ a...

PURPOSE To assess the value of MR in patients with sensorineural hearing loss (SNHL) caused by lesions other than acoustic neuromas. METHODS MR studies of 51 patients with SNHL were retrospectively reviewed; patients with acoustic neuroma were excluded to focus on the more uncommon causes. RESULTS Twenty patients had labyrinthine lesions. Six patients had viral labyrinthitis, one patient ha...
