Objectives: To estimate binaural asymmetric sensorineural hearing loss in own material of patients treated in Dept. of Phoniatrics and Audiology.
Material & Methods: The retrospective analysis was performed on the group of 1816 patients hospitalized in 2008 due to hearing disorders. Asymmetry of hearing loss was classified on Margolis and Saly criteria in PTA, and in ABR results in children.
Conclusions: Binaural asymmetric sensorineural hearing loss was found in 70 patients (3.9%). In a group of 46 differences of inter-aural threshold level in PTA were estimated on 21 to 30 dB. After audiological examination 14% of this patients were qualified for MRI investigation, in 2 (3%) of them acoustic neurinoma was found. The hearing aids fitting were performed in 44% of a group of 70 patients.

The organ of Corti, located in the inner ear, is the primary organ responsible for animal hearing. Each hair cell has a V-shaped or U-shaped hair bundle composed of actin-filled stereocilia and a kinocilium supported by true transport microtubules. Damage to these structures due to noise exposure, drug toxicity, aging, or environmental factors can lead to hearing loss and other disorders.

Background: It has been claimed that tacrolimus may have harmful effects on the auditory system, where it has been linked to ototoxicity and sensorineural hearing loss (SNHL). We evaluated silent SNHL in kidney transplant recipients (KTRs) receiving tacrolimus and the different factors affecting it compared to healthy controls.
Materials And Methods: In this case control study, hearing functions were studied in 42 KTRs receiving tacrolimus as maintenance immunosuppressive therapy for more than 3 months in comparison to 27 age- and gender-matched healthy subjects using tympanometry, pure-tone audiometry (PTA), extended high frequency audiometry (EHFA), and transient evoked oto-acoustic emissions (TEOAEs).

Platelet-rich plasma (PRP) contains high platelet concentration and growth factors that help in rapid wound healing, hemostasis, and decreased scarring. It has been used in various conditions to aid in healing, but its use in ear, nose, and throat (ENT) is not yet common. To compare the outcome of using PRP with myringoplasty with that of myringoplasty alone in the repair of tympanic membrane perforations.

Microtia and aural atresia present congenital ear anomalies that affect external ear and are associated with conductive hearing loss. Both anomalies result from exposure to various prenatal risk factors, most common during the first trimester of pregnancy. This study was aimed at epidemiological analysis of microtia/atresia and associated risk factors in the Kazakhstani population.
