Modified back-to-back autogenous conchal cartilage graft for caudal septal reconstruction: the medial crural extension graft.

OBJECTIVE To report our experience with the use of a modification of the back-to-back autogenous conchal cartilage graft, used as a medial crural extension graft, for reconstruction of the caudal septum. METHODS Retrospective review of all patients undergoing caudal septal reconstruction using a modification of the back-to-back conchal cartilage graft from January 1, 2007, through June 1, 2009, at a tertiary referral center. Photodocumentation of all patients was obtained preoperatively and postoperatively. Patients were asked to subjectively rate their functional and cosmetic outcomes at each follow-up visit. RESULTS Eight patients underwent caudal septal reconstruction with the modified back-to-back conchal cartilage graft during the time period studied. Six patients underwent caudal septal reconstruction via external septorhinoplasty while 2 patients underwent an endonasal approach. The median duration of follow-up was 12 months. At the last follow-up, patients rated their breathing as normal in 7 of 8 cases and improved, but not to normal, in 1 of 8 cases. Cosmesis was rated as excellent in 7 of 8 cases and good in 1 of 8 cases. There were no postoperative complications. CONCLUSIONS Modification of the back-to-back autogenous conchal cartilage graft used as a medical crural extension graft should be considered for reconstruction of the caudal septum in the cartilage deficient nose. The technique produces reliable outcomes with minimal donor site morbidity.
