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 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)
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 To study the qualities of laser myringotomy (LM) as a treatment for middle ear ventilation problems. DESIGN Prospective study and follow-up of consecutive cases of adults, children, and infants. Patients were observed for up to 2 years. SETTING Children underwent LM, with or without adenoidectomy, under general anesthesia in the operating(More)
OBJECTIVE The Harmonic Scalpel (HS) has been recently widely used to perform a variety of surgical procedures. We reviewed our experience with the use of HS in superficial parotidectomy to determine the safety and efficacy of this procedure, with regard to operative time, postoperative facial nerve function, and drainage output. STUDY DESIGN Nonrandomized(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)
Animal models for insulin resistance and type 2 diabetes are required for the study of the mechanism of these phenomena and for a better understanding of diabetes complications in human populations. Type 2 diabetes is a syndrome that affects 5-10% of the adult population. Hyperinsulinaemia, hypertriglyceridaemia, decreased high-density lipoprotein (HDL)(More)
OBJECTIVE Patients often complain of numbness of the tongue after otologic procedures; this symptom may occur with or without taste alterations.
