Evaluation of the outcome of myringoplasty in active versus inactive chronic otitis media without cholesteatoma

الملخص EN

Background : Myringoplasty is a procedure used to seal(reconstruct) a perforated tympanic membrane using a graft material by underlay or overlay techniques.

Temporalis fascia is the commonly used graft material.

Aim of study : to evaluate the difference in outcome of myringoplasty in cases of active and inactive chronic otitis media without cholesteatoma.

Patients and Methods : a prospective study of 54 cases of myringoplasty in adult age group whom age ranges from (20-40 years) and the duration of the disease ranges from (6-24 months).

All patients were complaining of chronic otitis media without cholesteatoma assessed clinically, audiologically and radiologically, all cases operated under general anesthesia and temporalis fascia grafting (underlay technique) via post-auricular incision.

Results: twenty six (48.2 %) patients had an active chronic otitis media without cholesteatoma while the remaining twenty eight (51.8 %) patients had an inactive chronic otitis media without cholesteatoma those with an active disease 21 (80.8 %) cases have successful closure of the perforation while in those 28 cases with an inactive disease 24 (85.7 %) cases have successful closure of the perforation.

Factors of gender, age, side of the perforation, duration of the perforation, and the pre-operative management for the active ears had no significant effect on the outcome of myringoplasty, P values = 0.5, 0.1, 0.9, 0.5, 0.6, 0.6 and 0.7 respectively which are > 0.05.

The overall percentage of success of grafting was 83.3 % and the failure of grafting was 16.7 %.

Conclusion :- The activity of the middle ear (infection) has little impact on the success rate of closure of tympanic membrane perforation
