Summary: | 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. |
