A Comparative Study of the Outcomes of 2 Surgical Procedures for Safe Type of Chronic Otitis Media
A Randomized Control Study of the Outcomes of Mastoidotympanoplasty Versus Tympanoplasty in Quiescent Tubotympanic Otitis Media
Mastoidotympanoplasty is a recognised surgery that is performed for chronic otitis media. But whether mastoidectomy in addition to tympanoplasty is really necessary in each and every case of quiescent chronic otitis media still remains controversial. Hence this study has been undertaken to study the differences in the outcomes of the 2 surgical procedures performed for chronic otitis media in a randomized control design.

Design: single blinded randomized control study. Setting: Tertiary referral medical college hospital. Sample size: 60. No of groups: 2 [30 cases in each group]. Group 1: Patients undergoing mastoidotympanoplasty. Group 2: Patients undergoing tympanoplasty only. No of strata: 3.


  1. Improvement of hearing
  2. Closure of tympanic perforation
  3. Recurrence of disease
  4. external ear canal stenosis

Tools for measurement of outcomes [before and after surgery]:

  1. Pure tone audiometry
  2. Impedance audiometry
  3. Otoendoscopy
  4. External ear canal dimensions
Phase 3
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single
Primary Purpose: Treatment
  • Chronic Otitis Media
  • Tubotympanic Disease
Procedure: mastoidotympanoplasty and tympanoplasty
