Evaluation of Role of Mastoid Surgery in the Management of Safe Chronic Suppurative Otitis Media.

This study evaluates the outcome of type 1 tympanoplasty with and with out mastoidectomy. The comparative study comprises of 40 patients with CSOM safe type in dry ear. All cases were operated during a period of one and a half years. 20 of these cases were selected for tympanoplasty alone (Group A) and 20 cases were selected for Tympanoplasty with cortical mastoidectomy (Group B). Patients were reviewed after 3 weeks for inspection of the operated ear. The second and third postoperative reviews were done 6 and 12 weeks respectively for clinical assessment of the operated ear with respect to graft status, ear discharge and hearing improvement. The postoperative audiograms were recorded after 3 months. Type I tympanoplasty with cortical mastoidectomy has better graft uptake (100 %) as compared to without mastoidectomy (95 %). Post-operative A-B gap closure is better in tympano-mastoidectomy (20.48 dB) than tympanoplasty (15.75 dB) with p value <0.05. Post-operative hearing gain and graft uptake were both better with tympano-mastoidectomy and tympanoplasty.
