    Abstract:
    BACKGROUND: The lower lateral cartilages (LLCs) are key elements for alar and tip support. Repositioning of both LLCs is an effective procedure for correcting a laterally spreading dome of LLCs and drooping nasal tip in cleft lip nasal deformity (CLND). The alar contour graft has become an essential component of rhinoplasty for correcting the concave or collapsed and retracted alar. Herein, onlay cartilage graft was combined with nasal tip plasty to correct hypoplastic cleft lateral crus or alar rim retraction, and with columella strut to obtain better aesthetic outcomes in patients with severe CLND. METHODS: Seven patients with severe secondary unilateral CLND, including hypoplastic cleft lateral crus or alar rim retraction, underwent rhinoplasty from October 2013 to April 2020. Both LLCs were isolated and repositioned approximated medially using tip suture technique combined with columella strut. A septal cartilage onlay graft was applied on the hypoplastic cleft lateral crus. Cartilage graft on the nasal tip was performed to further project and enhance the nasal tip. Photogrammetric evaluation of the operated patients and statistical analysis of the obtained data were performed. RESULTS: The average age at operation was 23.5 (range: 17-36) years. The follow-up period was 6-36 (mean, 14.3) months. All patients were enrolled by photogrammetric evaluation. Height of the medial nostril and short axis of the nostril on the cleft side were increased with a statistical significance of P < 0.05, indicating that depressed ala on the cleft side, which is a feature of CLND, was corrected similar to that of the noncleft side. CONCLUSIONS: The alar contour cartilage graft, as an effective adjunctive technique, improves the alar margin, prevents the alar rim from collapsing, and provides supports to the cleft-side alar rim. It can be a prophylactic measure to prevent postoperative retraction in patients with weakened LLCs. Lower lateral cartilage repositioning, columellar strut, and nasal tip plasty are useful for correcting severe secondary unilateral CLND.
