Comparative Study of the Outcome of Tympanoplasty Alone with Tympanoplasty Combined with Cortical Mastoidectomy in Patients with Quiescent Mucosal Chronic Otitis Media

Abstract

ABSTRACT Aims: 1. To compare the outcome of tympanoplasty alone with tympanoplasty combined with cortical mastoidectomy in patients with quiescent Chronic otitis media (COM). 2. To assess gain in hearing in dB. Materials and Methods: Patients diagnosed with mucosal type of chronic otitis media in the quiescent stage were selected. Two groups were formed. Patients were selected randomly and alternately they were included in groups A and B. The patients underwent otomicroscopy. Pure tone audiometry would depict pure conductive hearing of hearing loss. Group A (50% patients) were subjected to tympanoplasty alone and group B (other 50% patients) were subjected to tympanoplasty combined with cortical mastoidectomy. Prior to surgery, all patients underwent routine blood and urine examination, pure tone audiometry, and B/L mastoid X-ray Schuller’s view. Results: In our study, hearing gain in decibels in the tympanoplasty group was 17.1% and in tympanoplasty combined with cortical mastoidectomy was 21.1%. Graft uptake was 94% in the tympanoplasty group and 96% in tympanoplasty combined with cortical mastoidectomy. Recurrence of discharge was seen in three cases of tympanoplasty. Though tympanoplasty combined with cortical mastoidectomy is better in hearing improvement, graft uptake but the difference in two groups is statistically insignificant. Conclusion: Hearing improvement and graft uptake were statistically insignificant in two groups. Combining cortical mastoidectomy with tympanoplasty will not give additional benefits in terms of hearing gain and graft uptake in patients with quiescent mucosal chronic otitis. Media: Clinical significance: Hearing improvement and graft uptake were statistically insignificant in two groups. Combining cortical mastoidectomy with tympanoplasty will not give additional benefits in terms of hearing gain and graft uptake in patients with quiescent mucosal chronic otitis media.
