Myringoplasty with and without cortical mastoidectomy in treatment of non-cholesteatomatous chronic otitis media - "a comparative study", contineous study

Objective: 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 forty patients with non cholesteatomatous CSOM were recruited during the period of June, 2013 to December, 2014 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. 25 patients underwent simple myringoplasty alone and 25 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 and cortical mastoidectomy group . There was no significant difference in ear dryness between the myringoplasty alone group and cortical mastoidectomy group . Conclusion: Mastoidectomy performed in non cholesteatomatous CSOM gives a better chance for graft success rate and dryness of the middle ear. Mastoidectomy gives no statistically significant benefit over simple myringoplasty in the treatment of non cholesteatomatous CSOM. Keywords: TM perforation, myringoplasty, cortical mastoidectomy.Der Erstautor gibt keinen Interessenkonflikt an
