Technical refinements and outcomes of the modified anterior septal transplant

IMPORTANCE Severe anterior septal deviation and resultant nasal obstruction represent a difficult surgical task to correct. The goal of surgery is to straighten the anterior dorsal and caudal struts, while maintaining nasal tip and midvault support. This study presents a novel extracorporeal septoplasty technique to straighten the crooked anterior septum. OBJECTIVE To describe the novel anterior septal transplant technique, which consists of complete resection of the caudal septum and reconstruction with extended spreader grafts and a columellar strut, without a separate caudal septal replacement graft. DESIGN, SETTING, AND PARTICIPANTS This studywas a retrospective case series at a tertiary academic referral center. Participants were sequential adult patients undergoing anterior septal transplant from January 1, 2008, to December 31, 2015. MAIN OUTCOMES AND MEASURES Patient-reported nasal obstruction using Nasal Obstruction Symptom Evaluation (NOSE) scores and objective photographic analysis. Nasal tip deviation, projection, and rotation were measured. Preoperative and postoperative outcomes were compared. Complications are reported. RESULTS Seventy-one patients (mean age, 46 years [age range, 16-72 years]; 48 [67.6%] female and 23 [32.4%] male) were included in the case series. Postoperative NOSE scores (mean [SD], 24.00 [24.58]) were significantly better than preoperative NOSE scores (mean [SD], 72.25 [14.55]) (P < .001). A separate cohort of 32 patients (mean age, 42 years [age range, 13-72 years]; 23 [71.9%] female and 9 [28.1%] male) had photographs available for analysis. In the frontal view, nasal deviation improved from a mean (SD) of 2.9 (2.0) degrees before surgery to a mean (SD) of 1.4 (1.7) degrees after surgery (P = .004). In the base view, the deviation was corrected from a mean (SD) of 4.9 (2.8) degrees to a mean (SD) of 1.7 (1.2) degrees (P < .001). Tip rotation and projection were unchanged after surgery. Four patients had mild dorsal irregularities after surgery. CONCLUSIONS AND RELEVANCE Anterior septal transplant by the described technique is a safe and effective treatment option for severe anterior septal deviation. LEVEL OF EVIDENCE 4.
