OBJECTIVES/HYPOTHESIS To evaluate and compare the effect of chlorhexidine gluconate, povidoneiodine, and alcohol-three antiseptics used before ear surgery-on the function of the vestibular and cochlear parts of the sand rat's inner ear. The assessment of damage is based on the recording of vestibular evoked potentials (VsEPs) and auditory brainstem response(More)
OBJECTIVE Patients often complain of numbness of the tongue after otologic procedures; this symptom may occur with or without taste alterations. The purpose of this study was to objectively assess possible changes in the general sensation of the tongue in patients undergoing middle ear surgery. STUDY DESIGN AND SETTING Thirty-three individuals were(More)
OBJECTIVES/HYPOTHESIS To determine the incidence of measurable audiometric changes in the contralateral ear and clinical bilateral Menière's disease in individuals with longstanding established unilateral Menière's disease. STUDY DESIGN Analysis of data in an ongoing prospective study. METHODS One hundred and one patients who were treated with(More)
OBJECTIVES/HYPOTHESIS To define and assess the functional impairment of the vestibular part of the inner ear in a diabetic state, using a direct and objective test for evaluating the vestibular end-organ and an animal model for diet-induced type 2 diabetes mellitus. STUDY DESIGN Prospective controlled animal study. METHODS Two groups of sand rats(More)
OBJECTIVE To report the findings in patients with facial nerve schwannoma in whom surgery was elected at onset versus patients treated expectantly. STUDY DESIGN Retrospective case review. SETTING Tertiary referral center. PATIENTS Twenty-four patients with a mean age of 44 years (range, 18-65 yr) were followed for an average of 6 years (range, 1-19(More)
The human fetus in utero is able to respond to sounds in the amniotic fluid enveloping the fetus after about 20 weeks gestation. The pathway by which sound reaches and activates the fetal inner ear is not entirely known. It has been suggested that in this total fluid environment, the tympanic membrane and the round window membrane become 'transparent' to(More)
OBJECTIVE The hallmark of bone conduction audiometry in otosclerosis is the "Carhart notch." The mechanism for this phenomenon is still not clearly understood. The objective of this study was to describe the pattern of bone-conduction threshold responses preoperatively in patients with otosclerosis and to assess overclosure after laser-assisted stapedotomy.(More)
OBJECTIVE The aim of this study was to determine the trends in otorhinolaryngological (ORL) publications from 1993 to 2007. METHODS In order to retrieve as many ORL-related articles as possible we used two strategies of literature analysis. Both were based upon ORL Medline articles from 1/1/1993 to 31/12/2007. In the first strategy, we attempted to(More)
Classically it has been thought that bone conduction activation at the mastoid leads to relative motion between the stapes footplate and the oval window due to inertial and to compression (distortion) mechanisms. However, several recent clinical findings and experimental manipulations may point to additional mechanisms. These manipulations were extended in(More)
The effect of previous noise induced hearing loss (NIHL) on subsequent NIHL was studied in rats. Three groups of animals were initially exposed to different durations of 113 dB SPL broad band noise (21 days, 3 days or 0 days--unexposed). Their permanent threshold shifts (PTS) from this exposure (PTS1) were evaluated using auditory nerve-brainstem evoked(More)
