Objective: To compare the surgical outcome of tympanoplasty in smokers and nonsmokers. Design: Prospective cohort study. Setting: Tertiary Care Center in Central India. Patients: The study included 245 male patients who underwent type 1 tympanoplasty and were subsequently divided into 2 groups. Group A: Nonsmokers (115 patients). Group B: Smokers (130 patients). All the cases were operated by postaural route and underlay technique. Revision cases and patients with systemic disease were excluded from the study. Main Outcome Measures: The success rate and hearing gain at the last follow-up i.e., 6 months from the day of surgery. Results: The overall success rate of tympanoplasty in our study is 91.3% in nonsmokers and 73% in smokers. Most of the patients were in the age group 15–30 years. Smokers had significantly longer duration of complaints associated with chronic suppurative otitis media. Preoperatively, eustachian tube dysfunction was assessed by tympanometry and it showed a significant difference in both the operated and the nonoperated ears of smokers. Sclerosis in X-ray mastoid Schuller's view was seen more in smokers than in nonsmokers (P = 0.001). There was a significant difference in otomicroscopic findings of smokers and nonsmokers i.e. more patients with grade 3 and 4 pars tensa retractions in the contralateral ear (P = 0.0001). Mean gain in the postoperative air-bone gap was significantly more in nonsmokers as compared to smokers (P = 0.013). Conclusion: Smoking is a definitive risk factor in the success of tympanoplasty in terms of graft take up and hearing gain.
