Septal Integration Graft, a Modified Direct Type of Septal Extension Graft for the Treatment of Unilateral Cleft Lip Nose Deformity: An Anthropometric Analysis.

Abstract

The purpose of this study was to evaluate the cosmetic outcomes and stability of septal integration grafts (SIGs), a modified direct type of septal extension graft, in patients with cleft lip nose deformity. Seventy-three patients underwent SIGs between January 2002 and July 2017. The exclusion criteria were patients who lacked clinical photographs preoperatively or postoperatively. We reviewed data regarding the patient demographics, combined procedures, and complications as well as preoperative and postoperative clinical photography. Eleven measurement items were evaluated from basal and right lateral views with photogrammetry and 3-dimensional anthropometry using standardized clinical photographic techniques. Sixty-one patients were analyzed in this study. Twelve patients were excluded owing to a lack of postoperative photographs. The mean ± SD follow-up period was 26.70 ± 29.43 months (range, 6-134 months). Compared with the preoperative value, the nasal tip projection index, height of nose index, and nostril axis inclination significantly improved. The columellar length (Rt-Lt) index significantly decreased, which implied improved columellar deviation. Complications included hematoma (n = 1), wound dehiscence (n = 1), tearing of septal mucosa (n = 3), and silicone implant deviation (n = 2). We used SIGs to correct nasal deformity in patients with cleft lip nose deformity. The SIG can minimize the amount of the graft used for septal extension and can effectively correct nasal tip and columella deformities.
