Abstract: Objective: To discuss an effective method of cheiloplasty for postoperative nasal deformity after unilateral severe cleft lip. Methods: Seventy-six patients with secondary cleft lip nasal deformity were repaired with alar cartilage-muscle rings by remov al of the points of theattachment of the nasal columella basement through a “V-Y” incision andimplant ation of an autologous rib cartilage tissue around the piriform aperture The short-and long-term responses were observed. Results: All got primary healings. Followed up for 12-38 months, the apex of nose, nasal ala, nostrils and nasal columella produced satisfied outlines. Conclusions: Alar cartilage-muscle ring is hypoplastic, which results in nasal myosthenic disequilibrium. Reconstruction of the alar cartilage-muscle ring plays a key role in the correction of nasal deformities for cleft lip patients.
