Abstract
BackgroundChronic otitis media is one of the major health issues worldwide resulting in partial or complete loss of conductive hearing mechanism including the tympanic membrane and ossicular assembly. The aim of the study is to assess hearing improvement after reconstructing the incudo-stapedial joint with glass ionomer cement. Here, a prospective observational study was done in a tertiary care hospital. Patients of chronic mucosal otitis media were operated, and intraoperatively incudo-stapedial joint discontinuity was restored using glass ionomer cement. Post-operative follow-up was done at 1-month, 3-month, 6-month, and 1-year intervals, and hearing was evaluated by doing pure tone audiometry with air conduction at 0.5, 1, 2, 3, 4, 6, and 8 kHz and bone conduction at 0.5, 1, 2, 3, and 4 kHz. Tabulation was done by calculating the air-bone gap in each patient.ResultsIn our study, the patients showed statistically significant improvement in air conduction thresholds and near closure of air-bone gap post-operatively. The mean AC threshold is 15 dB with 91.67% patients having closure of ABG < 20 dB at the end of the 3rd month. Hearing was also evaluated at 6-month and 1-year intervals, which showed good improvement in hearing levels.ConclusionsGlass ionomer is a simple, physiological, and cost-effective method of tympano-ossicular reconstruction with certain significant post-operative hearing improvement.
Highlights
Chronic otitis media is one of the major health issues worldwide resulting in partial or complete loss of conductive hearing mechanism including the tympanic membrane and ossicular assembly
Pure tone audiometry correlated with ossicular discontinuity with average air conduction (AC) threshold > 40 to 50 dB hearing loss
Post-operative follow-up was done at 1-month, 3-month, 6-month, and 1-year intervals, and hearing was evaluated by doing pure tone audiometry with air conduction (AC) at 0.5, 1, 2, 3, 4, 6, and 8 kHz and bone conduction at 0.5, 1, 2, 3, and 4 kHz
Summary
Patients of chronic mucosal otitis media were operated, and intraoperatively incudo-stapedial joint discontinuity was restored using glass ionomer cement. Chronic otitis media is one of the major health issues worldwide resulting in partial or complete loss of conductive hearing mechanism including the tympanic membrane and ossicular assembly. The aim of this study is to assess hearing improvement after reconstructing the incudo-stapedial joint with glass ionomer cement. Glass ionomer cement comprises inorganic glass particles surrounded by an insoluble hydrogel matrix It is biocompatible, biostable, moldable, cost-effective, and universally available [5,6,7,8,9]. This study is necessary to access the post-operative hearing improvement and how much reliable the procedure is
