Transcanal endoscopic type 3 tympanoplasty with mastoid preservation for advanced active chronic mucosal otitis media.

BACKGROUND

Chronic mucosal otitis media is a very common ear disease for which patients attend otolaryngology clinics. Most of these patients present with actively discharging ears.

AIMS/

OBJECTIVES

This study aims to observe the middle ear space pathology and obtain surgical outcomes as a treatment for patients with advanced chronic mucosal otitis media with a transcanal endoscopic ear surgery approach.

MATERIALS AND

METHODS

A prospective study was designed, and patients suffering from chronic mucosal otitis media in the active suppurative phase with an air-bone gap larger than 20 dB were included.

RESULTS

70 operated ears were included. Underlying macroscopic pathology within the middle ear space was observed: Middle ear granulomas at 58.6%; Tympanosclerosis 41.4%. Blockage of the tympanic isthmus was evaluated, obtaining a blockage rate of 81.4%. At 12 months of evaluation after surgery, a postoperative ABG < 20 dB was achieved in 85.7% of the operated ears. An overall closed tympanic membrane was obtained in 88.6% of the patients.

CONCLUSION

This prospective cohort study shows the short-term efficacy of transcanal endoscopic type 3 tympanoplasty with mastoid preservation for managing advanced chronic mucosal otitis media. Clinical trials are required to give more evidence to the present matter.
