Background: pneumatization of the middle turbinate is common anatomic variations of lateral nasal wall, whereas rare in the superior and the inferior turbinate. Objective: to compare the efficacy of conchoplasty to lateral partial turbinectomy in the treatment of concha bullosa. Patients and Methods: this study included randomly selected 40 patients, who attended the ENT clinic at Al-Hussein University Hospital, Faculty of Medicine, Al-Azhar University during the period from June 2016 to November 2017.All patients have a symptomatic unilateral or bilateral concha bullosa. Patients were classified randomly into 2 groups; Group (1): 20 patients (50%) underwent lateral partial turbinectomy. Group (2): 20 patients (50%) underwent conchoplasty. Results: there was complete cure or significant reduction in severity of complaints in 15 patients (75%) who underwent LPT. In the conchoplasty group 17 patients (85%) were significantly symptoms free at the end of the follow up period. 1 case which underwent LPT developed post-operative epistaxis requiring intervention. There were no cases of epistaxis requiring intervention in the conchoplasty group. Other complications noted in the LPT group included synechiae formation in three cases (15%). Conclusion: as compared to lateral partial turbinectomy, conchoplasty is an equally effective surgery in the treatment of concha bullosa with lesser incidence of complications.
