Abstract
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 3weeks for inspection of the operated ear. The second and third postoperative reviews were done 6 and 12weeks respectively for clinical assessment of the operated ear with respect to graft status, ear discharge and hearing improvement. The postoperative audiograms were recorded after 3months. 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 (20.48dB) than tympanoplasty (15.75dB) with p value <0.05. Post-operative hearing gain and graft uptake were both better with tympano-mastoidectomy and tympanoplasty.
