OBJECTIVE To determine the hearing outcome in patients undergoing surgery via the retrosigmoid approach for acoustic neuromas with a substantial component in the cerebellopontine angle. STUDY DESIGN Retrospective case review. SETTING Tertiary referral center. PATIENTS The medical records of all patients undergoing acoustic neuroma removal via the(More)
The Kresge Hearing Research Institute-3 (KHRI-3) antibody binds to a guinea pig inner ear supporting cell antigen (IESCA) and causes hearing loss. To gain insight into the mechanism of antibody-induced hearing loss, we used antibody immunoaffinity purification to isolate the IESCA, which was then sequenced by mass spectroscopy, revealing 10 guinea pig(More)
OBJECTIVE The object of this study was to compare the expression of epidermal growth factor, interleukin-1alpha, and tumor necrosis factor-alpha in chronic otitis media with or without cholesteatoma. BACKGROUND It has been reported that cytokines and epidermal growth factor are effective in the bone resorption process in chronic otitis media. Bone(More)
OBJECTIVE To describe the underrecognized inner ear malformation characterized by complete aplasia of the labyrinthine semicircular canals associated with a relatively well-formed cochlea, to investigate its relationship with known syndromic forms of hearing loss, and to hypothesize regarding the potential embryopathogenesis of this anomaly. STUDY DESIGN(More)
HYPOTHESIS The goals of this study were to identify the effects of hypercholesterolemia on the cochlea and to find out where the pathologic changes first occur. BACKGROUND Some authors have stated that hypercholesterolemia alone does not produce auditory dysfunction. Others propose that auditory dysfunction is caused by glycogen accumulation and other(More)
Aim of the study was to investigate whether postoperative middle and late latency responses (MLR and LLR) give some clues of postoperative performance of cochlear implant (CI) users. The study was performed in ten prelingual and six postlingual-CI patients with the age ranging from 6 to 48 years (mean 19.7 +/- 15.7 years). The following criteria were sought(More)
OBJECTIVE To document immunologic findings in patients with recurrent facial paralysis (RFP) and to compare the results of the surgery with the results of medical treatment. STUDY DESIGN Retrospective case review. SETTING Tertiary care referral center. PATIENTS Nine patients with RFP were reviewed. INTERVENTION Patients underwent nonspecific(More)
We aimed to investigate if there is a concordance between summation potential (SP)/action potential (AP) ratio and unilateral weakness in patients with definite-Meniere's disease. There were two groups, a group of unilateral definite-Meniere patients who received no treatment and another group of control subjects. Twenty-six patients were identified as(More)
OBJECTIVE Conscious and deceptive exaggeration of hearing loss is termed pseudohypacusis. Even though the Stenger test has been used in the management of pseudohypacusis for almost a century, its sensitivity, specificity and predictive values for unilateral pseudohypacusis have not previously been reported, to our best knowledge. We investigated the(More)
OBJECTIVE To evaluate the validity of early (within 3 wk) and late-term (after 3 wk) electroneurography (ENoG) findings in Bell's palsy (BP) to predict the prognosis. STUDY DESIGN Retrospective case review. SETTING Tertiary referral center. PATIENTS Patients with peripheral facial paralysis with no identified cause. All patients were given the same(More)
