- Abstract
During recent years there was many approaches to have better hearing preservation rate during Cochlear implant surgery with residua hearing (Partial Deafness Treatment). The aim of the study was to assess how different models of steroid therapy influence hearing preservation after cochlear implantation. Eligibility criteria were: age ≥ 18 years, cochlear duct length ≥ 27.1 mm based on the computed tomography (CT) scan and hearing levels within following limits: 10-120 dB in frequencies 125-250 Hz, 35-120 dB in 500-1000 Hz, 75- 120 in 2000-8000 Hz. Exclusion criteria were occurrence of symptoms or diseases with cautious use or contraindication for steroid therapy and taking medicines that increase the steroids effects. Patients included in the study were divided into 3 groups: intravenous steroid administration, intravenous + oral steroid administration and a control group. Hearing preservation was established based on pure tone audiometry (frequencies 125-8000 Hz, both octaves and semi-octaves) according to ISO 8253-1:2010. Hearing preservation was calculated based on the pre- and postoperative average hearing levels (PTA) according to special formula developed by the Hearring Group. 36 patients were included in the study. In all cases the cochlear implant electrode was inserted via the RW approach with a straight electrode length 28 mm. Patients with prolonged application of steroids had better results than standard steroid application and control group. The steroid therapy stabilizes hearing thresholds and enables to preserve hearing abilities in adult patients. Combination of intravenous and oral steroid therapy seems to be the most optimal administration model.
