Assessment of auditory abilities is important in the diagnosis and treatment of children with autism. The aim was to evaluate hearing objectively by using transient evoked otoacoustic emission (TEOAE) and auditory brainstem response (ABR). Tests were performed on 30 children with autism and 15 typically developing children, following otomicroscopy and(More)
OBJECTIVE The aim of this prospective study is to evaluate the differences in the ability to view structures in the middle ear between Tos modified canal wall-up mastoidectomy and classic canal wall-up (CWU) and canal wall-down (CWD) mastoidectomies. METHODS Eighteen temporal bones of 10 cadaver heads were used. Six bones were randomly selected for each(More)
OBJECTIVE To compare the Eustachian tube patency and function after tympanoplasty with either cartilage palisades or fascia grafting after one-stage surgery in children with tensa cholesteatoma. STUDY DESIGN In children operated for tensa cholesteatoma, cartilage palisade tympanoplasty was performed in 32 ears and fascia tympanoplasty in 29 ears. The(More)
OBJECTIVE Medial olivocochlear efferent (MOCE) neurons innervate outer hair cells (OHCs) of the cochlea, which in turn leads to basilar membrane motion. We hypothesized that MOCE-induced alterations in basilar membrane motion, independent of traveling waves, is responsible for the cochlear frequency discrimination of sound. MATERIALS AND METHODS Eleven(More)
Primary chondroid tumors of the larynx represent less than 1% of all laryngeal tumors. Most of them are chondromas and they often involve to the cricoid cartilage. A 31-year-old male patient applied to the oto-laryngology service with a history of dysphonia and dyspnea. Microlaryngoscopy revealed 2 cm sized, ill-defined, covered with regular mucosa, porous,(More)
The aim of the present study is to evaluate the effect of swallowing type (dry versus wet) on the outcome of a nine-step inflation/deflation tympanometric Eustachian tube function (ETF) test in healthy adults. Fourteen normal healthy volunteers, between 19 and 28 years of age, were included in the study. The nine-step test was performed in two different(More)

OBJECTIVE Eustachian tube dysfunction plays an important role in the pathogenesis of middle ear barotrauma. This investigation evaluates the predictive value of several parameters related to tubal dysfunction, in relation to symptomatic middle ear barotrauma in divers. STUDY DESIGN Prospective and blinded. PATIENTS Thirty-one sport scuba divers with(More)
The possible cochlear toxicity of topically applied povidone-iodine solution was investigated in guinea pigs by measuring transiently evoked otoacoustic emissions (TEOAEs). Seven adult pigmented guinea pigs (14 ears) with a normal acoustic pinna reflex were used. After the baseline TEOAE measurements, 0.1 mL of povidone-iodine solution was applied(More)
