The middle ear of guinea pigs has long been used for experimental studies, but no detailed information about its temporal bone anatomy is available. In 18 adult guinea pigs, the temporal bone, eustachian tube, and inner ear anatomy, in addition to the anatomy of the middle ear, were investigated under the dissection microscope. In addition to properties of(More)
OBJECTIVE This study aimed to evaluate retrospectively the results of experience with end-to-end anastomosis of cranial nerves VII and XII, performed due to transection of the facial nerve during acoustic neuroma removal. METHODS We assessed the facial reanimation results of 33 patients whose facial nerves had been transected during acoustic neuroma(More)
OBJECTIVE MESNA is a synthetic sulfur compound that produces mucolysis by disrupting disulfide bonds. This study aimed to address indications and technique of MESNA application in otologic surgery, especially in retraction pockets and adhesive otitis media. METHODS MESNA application was performed in 42 ears of 39 patients. The diagnoses were retraction(More)
Of 97 extracranial complication cases, 41 (42.3%) were female and 56 (57.7%) were male with ages ranging from 5 to 83 years (mean age, 43.9 years). Two (2.1%) patients were in the first decade, 9 (9.3%) in second, 16 (16.5%) in third, 22 (22.7%) in fourth, 8 (8.2%) in fifth, 17 (17.5%) in sixth, 13(13.4%) in seventh, 7 (7.2%) in eighth and 3 (3.1%) in ninth(More)
OBJECTIVE In this study, our aim was to determine presence of dysfunction in the efferent auditory system of children with type-I diabetes mellitus (DM) presenting no evidence of symptomatic neuropathy. METHODS Thirty children with type-I DM (DM group) and 31 age matched healthy children (control group) with normal hearing and middle ear function were(More)
OBJECTIVE The objective was to provide information about methods used and preliminary outcomes for pediatric ABI (auditory brainstem implant). STUDY DESIGN An analysis of outcome was performed in children who received an ABI. METHODS Twelve children received a MED-EL ABI system. Progress in audition and language was monitored through parental reports,(More)
BACKGROUND The aim of this study was to present our technique of posterior fossa surgery and to evaluate whether cerebellar retractors are needed. METHODS Since March 1989, more than 500 surgeries were performed through retrosigmoid approach, and our surgical technique was described. The data were evaluated whether or not cerebellar retractors were used(More)
The objective of this study was to evaluate the importance of endoscopes in eliminating the disadvantage of posterior fossa approach-that is, the lack of adequate visualization obtained of the lateral aspect of the internal acoustic canal (IAC). Over a 10-year period 32 patients underwent removal of acoustic neuroma (AN) via a combined retrosigmoid(More)
The adenoidal-nasopharyngeal ratio (ANR) was proposed as a convenient and practical method to evaluate adenoidal enlargement. We analyzed cephalometric radiographs of 150 children divided into 6 subgroups according to clinical assessment (possible adenoidectomy candidates [PACs] and controls) and age. Our purpose was to investigate the predictive(More)
