Hearing outcomes after Mastoidectomy
Introduction: Mastoidectomy remains an important procedure for the management of some cases of chronic otitis media (COM). Our objective is to assess hearing results after canal wall up (CWU) and canal wall down (CWD) mastoidectomy.
Material and Methods: Retrospective review of mastoidectomies undertaken between 2012 and 2016 at a Portuguese hospital.
Results: 89 surgeries were analyzed. Both CWU and CWD mastoidectomies showed mean hearing gain of 7 dB. Cholesteatomatous COM was more common among surgeries which improved and which worsened hearing. However, proportion of noncholesteatomatous disease was significantly higher (p=0.025) in surgeries that deteriorated hearing.
Discussion/Conclusion: This study does not indicate any trend in order to solve the debate concerning the performance of mastoidectomy in cases of noncholesteatomatous COM. Nonetheless, option between CWU or CWD techniques should be not influenced by previous grade of hearing loss and presence or not of a contralateral functional ear.Author(s): Pedro Carneiro de Sousa* , Joana Borges da Costa, Delfim Duarte, Nuno Trigueiros
