Post-surgical changes in wideband absorbance in paediatric cochlear implant users after mastoidectomy and posterior tympanotomy.

Background: Although Cochlear implantation (CI) is effective in restoring hearing for children with severe-to-profound sensorineural hearing loss, it may influence the middle ear mechanics, potentially causing an air-bone gap and altering middle ear stiffness, which is not detected by traditional 226 Hz tympanometry.

Aims/objectives: To investigate the effect of mastoidectomy posterior tympanotomy (MPTA) on wideband absorbance (WBA) in children with CI.

Materials And Methods: The study included 20 normal-hearing children (normal group) and 10 children with CIs who underwent MPTA (CI-MPTA group), aged 3-10 years.

Wideband Absorbance Pattern and its Diagnostic Value in Adults with Middle Ear Effusions and Tympanic Membrane Perforation.

Background:: Middle ear effusion (MEE) and tympanic membrane perforation (TMP) are difficult to distinguish using existing immittance techniques, necessitating the use of a separate test battery. Wideband absorbance (WBA) tympanometry is a new enhanced technique, and studies have shown a reliable WBA pattern to identify middle ear disorders. Thus, the study was performed to determine the WBA across the frequencies in ears with MEE, TMP, and compared with normal hearing individuals.

Prevalence of Hearing Impairment in High-Risk Neonates at Kalaburagi Region of Northern Karnataka: A Hospital-Based Cross-Sectional Study.

The study estimated the prevalence of hearing impairment in high-risk neonates and effect of high-risk factors on the hearing. A hospital-based cross sectional study was conducted on 327 neonates with high-risk factors. All the high-risk babies were screened using TEOAE and AABR followed by diagnostic ABR testing.

Wideband absorbance tympanometry: a novel method in identifying otosclerosis.

Purpose: The purpose of the study was to know whether the wideband absorbance measurements can be a useful tool to identify ears with otosclerosis. The present study analyzed WBA measurements and highlighted its effectiveness in identifying ears with otosclerosis and differentiating from healthy normal ears.

Methods: The study included 42 ears with otosclerosis which were compared with an equal sample size of healthy normal ears.

Wideband absorbance pattern in adults with otosclerosis and ossicular chain discontinuity.

Objectives: Evidence from previous literature had shown that the use of a single frequency probe tone is not sensitive enough to detect middle ear pathologies, especially related to the ossicles, which hinders accurate diagnosis. The goal of the present study was to compare the outcome of wideband absorbance (WBA) tympanometry and to determine the difference in WBA pattern in adults with otosclerosis and ossicular chain discontinuity.

Materials And Methods: Estimated adult cases of otosclerosis (10 ears) and ossicular chain discontinuity (06 ears) along with healthy individuals (10 ears) in the age range of 24 to 48 years (mean age: 38.
