“Diagnostic implementation of impedance audiometry as an OPD procedure in patients with conductive deafness : An overview”
Journal Title: PARIPEX-Indian Journal of Research - Year 2017, Vol 6, Issue 3
Abstract
Impedance audiometry is an objective technique which evaluates middle ear function by three procedures: Static immittance, Tympanometry and the measurement of acoustic reflex threshold sensitivity. The study aims to demonstrate the clinical implementation and usefulness of impedance audiometry in diagnosis of pathology involving the middle ear causing conductive hearing loss. The study was conducted in the department of ENT Muzaffarnagar medical college for a period of 18 months (i.e from Jan-2015 to June-2016), comprising 232 ears of 125 patients. The patients were divided in 2 groups: 1. 75 patients (Male = 39, Female = 36 with conductive deafness aged between 10-60 years) - 139 ears 2. 50 normal control cases (Male = 42, Female = 8, Aged between 10-60 years) - 93 ears. Impedance audiometry was done to evaluate the type of middle ear pathology in patients with conductive deafness and for establishment of type of deafness additional methods - Tuning fork test’s and Pure tone audiometry were done. The results were interpreted according to the parameters of impedance audiometry i.e static compliance, tympanometry (tympanogram type) and acoustic reflex. Based on the clinical study results we could estimate the tympanometry as an objective and informative method for diagnosis of type of conductive hearing loss.
