Myringoplasty with and without Cortical Mastoidectomy in Treatment of Non-cholesteatomatous Chronic Otitis Media: A Comparative Study

OBJECTIVE To compare the outcome and success of repair of uncomplicated tympanic membrane perforations with myringoplasty alone and when combined with mastoidectomy. METHODS A prospective study where 40 patients with non-cholesteatomatous chronic suppurative otitis media (CSOM) were recruited during the period of June 2013 to December 2013 from the outpatient clinic of Otorhinolaryngology department, Faculty of medicine, Cairo University. Patients were managed medically and after dryness of their perforations they were operated upon. Twenty patients underwent simple myringoplasty alone and 20 patients underwent myringoplasty with cortical mastoidectomy. Underlay technique with temporalis fascia was done for all patients. Follow-up period was at least 3 months. RESULTS Hearing improvement was comparable in both groups. There was no significant difference in graft uptake between the myringoplasty alone group (70%) and cortical mastoidectomy group (80%) (P = 0.7). There was no significant difference in ear dryness between the myringoplasty alone group (75%) and cortical mastoidectomy group (90%) (P = 0.4). CONCLUSION Mastoidectomy performed in non-cholesteatomatous CSOM in this study gives no statistically significant benefit over simple myringoplasty as regards graft success rate and dryness of the middle ear with comparable hearing outcome.
