Conductive Hearing Loss with Present Acoustic Reflex: A Case Report
Acoustic reflex is a sensitive indicator of middle ear lesions when the tympanic membrane is intact and tympanometry is normal. Acoustic reflex is not usually observed in conductive hearing loss caused by disruption of the ossicular chain including ossicular discontinuity and fixation. Ossicular disruption can show at least partially intact acoustic reflex under a certain condition. Moreover, o...
متن کاملDiagnostic utility of the acoustic reflex in predicting hearing in paediatric populations.
INTRODUCTION AND OBJECTIVES The sensitivity of prediction of acoustic reflex, in determining the level of hearing loss, is especially useful in paediatric populations. It is based on the difference between the pure tone stapedius reflex threshold and contralateral white noise. The white noise threshold was 60 dB and that of pure tone was 80 dB. Our objective was to determine the diagnostic sens...
متن کاملAcoustic neuroma presenting as sudden hearing loss.
Sudden hearing loss occurs as the initial symptom in 1 to 9 per cent of all acoustic neuromas. A case of an acoustic neuroma presenting with sudden hearing loss is described. In this case, the hearing thresholds returned to normal. To the authors' knowledge, this is the first case in which an acoustic neuroma presenting with sudden hearing loss exhibited a return to normal thresholds. This sugg...
متن کاملAcoustic reflex threshold tenth percentiles and functional hearing impairment.
This study addressed the issue of whether functional impairments can be identified or confirmed using tonal acoustic reflex thresholds (ARTs). Tonal ARTs from 74 ears with functional impairments were compared to 10th percentiles of the ARTs for normal and cochlear-impaired ears at 500 to 2000 Hz (Gelfand, Schwander, and Silman, 1990). Only one ear (5.3%) was correctly identified among the 19 ea...
متن کاملPredicting hearing loss in facioscapulohumeral muscular dystrophy.
Facioscapulohumeral muscular dystrophy (FSHD) has an estimated prevalence of 4–7 per 100,000 population, making it the third most common type of muscular dystrophy. The classic form of FSHD is characterized by weakness that is slowly progressive and often asymmetric in the face, scapulae, upper arms, lower legs, and abdomen. The age at onset of symptoms varies from infancy to middle age, and li...
