Cartilage tympanoplasty: a reliable technique for smokers

Abstract

The aim of this study was to report our experience with cartilage tympanoplasty (CT) in smokers and compare it with that of non-smokers using a retrospective chart review at a tertiary referral center. Between September 2008 and September 2010, cartilage tympanoplasty was performed in 52 patients. Among them, 27 were active smokers and 25 former or non-smokers. The entire tympanic membrane was replaced with conchal cartilage, shaped either as a shield for cases with intact canal wall mastoidectomies, or crashed for cases with canal wall down procedures. The mean post-operative follow-up was 12 months (range 6-18 months). A complete pre- and post-operative audiologic evaluation was obtained in all patients. Graft take was successful in all patients. The overall average pre-operative and post-operative pure tone average air-bone gaps (PTA-ABG) was 52.2 dB ± 17.7 dB and 35.4 dB ± 17.9 dB, respectively, with an overall improvement of 16.8 dB (p < 0.001). A post-operative PTA-ABG of 25 dB or less was achieved in 39 (75 %) patients (p < 0.001). In smokers, the hearing improvement was 17.6 dB (p < 0.001) with a PTA-ABG of 25 dB or less in 19 (70 %). In non-smokers, the average hearing improvement was 16.8 dB (p < 0.0005) with a post-operative PTA-ABG of 25 dB or less in 19 (76 %), (p < 0.001). The results showed that the CT technique is a very effective procedure for smokers. Excellent graft take and satisfactory hearing results can be accomplished regardless of smoking habits.
