Abstract：Objective To review treatment outcomes of revision surgery in chronic suppurative otitis media by compar-ing postoperative assessment findings between revision and first surgery. Methods Data from 16 patients (16 ears) who under-went revision surgery operated by the corresponding author were reviewed. Sixteen separate cases with matched age, history of disease, gender and surgical method were chosen for a paired analysis. The 32 patients were followed up to assess postopera-tive complications for at least 3 months and their pre- and postoperative pure tone threshold results were documented. Postop-erative mean air-bone gap (ABG)≤20dB and air conduction gain (ACG)≥10dB were set as evaluation standards. Results 7 pairs underwent simple tympanoplasty, 9 pairs underwent tympanoplasty and canal-wall-down mastoidectomy. The percent-age of postoperative mean ABG≤20dB was 43.8%after revision surgery compared with 68.8%after first time surgery (P=0289). The percentage of ACG≥10dB after revision surgery was 62.5% compared with 50.0% after,first time surgery (P=0.754). The percentage of ABG≤20dB and ACG≥10dB was 31.3%after revision surgery compared with 43.8%after first time surgery (P=0.687). No postoperative complication was found in either group. Conclusion Postoperative recrudescence or failed hearing improvement can be operative indications for tympanoplasty. Revision surgery is an effective treatment to clear lesions and improve hearing outcomes.
