목적: We present our 9-year experience of nasal septal perforation repair focusing on surgical techniques and outcome. 방법:From September 2006 to June 2014, 30 patients (MF=237, mean age = 42 years old) who underwent septal perforation repair in Boramae medical center were investigated. Etiology, perforation size, presenting symptoms, surgical techniques, results and complications were analyzed through chart review. The mean postoperative follow- up duration was 36 months. 결과:Causes of perforations were mostly previous surgery (57%) and trauma (27%). The size of the perforation ranged from 2 to 30 mm with an average of 12.8 mm. For surgical repair, external rhinoplasty approach was used in 23 patients (77%) and endonasal approach in 7 patients (23%). Rhinoplasty was combined in 17 patients (57%) and most of them were performed via external approach. The approach was mainly decided by the need for simultaneous rhinoplasty, not by the perforation size. Perforation was closed bilaterally in 29 patients (93%) with interposition graft insertion in 24 patients (80%). Intranasal advancement flap, rotation flap, or combination of both was used to repair the perforation. When the perforation size was larger than 15 mm, rotation flap was mainly used. Complete closure with symptom relief was achieved in 25 cases (83%) without any serious complication. The closure rate was not affected either by the approach method (p=0.334) or the perforation size (p=0.271). In failed 5 patients, the symptoms and the perforation size decreased. Proposed reasons for failure were diverse. 결론:We could successfully close the diverse septal perforation of which size not exceeding 30 mm in 83%. Intranasal advancement/rotation flap, bilateral flap closure, and interpositional graft were main factors for surgical success.
