The role of allergic and nonallergic rhinitis on success of type 1 cartilage tympanoplasty.

To investigate the role of allergic rhinitis (AR) and non-allergic rhinitis (NAR) on success of type 1 cartilage tympanoplasty. This prospective study was conducted on 60 patients who had type 1 cartilage tympanoplasty. The patients were divided into three groups as no-rhinitis (n = 28), NAR (n = 18) and AR (n = 14) groups, based on their symptoms, skin prick tests and/or serum specific IgE levels. AR and NAR groups were treated for their rhinitis symptoms both pre- and postoperatively. The patients were followed up for a minimum of 6 months and compared for graft success rates and audiological outcomes. Three study groups were similar for age, gender distributions and preoperative air-bone gaps (p = 0.780, p = 0.167 and p = 0.676, respectively). Postoperative graft perforation rate was 0% in no-rhinitis and AR groups while it was 16.7% in NAR group, with a significant difference among three groups (p = 0.034). The comparison of three study groups for change in the postoperative air bone gaps in comparison with preoperative air bone gaps did not yield any statistically significant result (p = 0.729). Although AR does not result in failure of type 1 cartilage tympanoplasty in patients treated for rhinitis compared to the control group, NAR does. Pre- and postoperative treatment of patients for rhinitis and employment of cartilage graft may be the key factors for success of surgery in patients with AR. Further studies with a larger sample size are needed.
