Outcome of double-cut correction on secondary deformity after unilateral cleft lip repair with nasolabial muscle reconstruction

Abstract

Objective To investigate the surgical methods and effect of double-cut nasolabial muscle directional three-dimensional reconstruction on the secondary deformity of unilateral cleft lip repair. Methods We first increased a contralateral vermilion secondary incision based on the nasolabial muscle directional three-dimensional reconstruction, without damaging the contralateral white lip skin, via suturing both sides of nose wings bundle of nose outside corner under the columella muscle, and overlapping suturing both sides of the orbicularis muscle flap, and then rebuilt and took shape of the nest and the crest. Results All incisions healed well in 18 patients, all nasal deformities were corrected better than the traditional methods, with the nasal base plump, the nasal sill formed close to the contralateral side, and rebuild the philtrumdimple and philtrum crest, with clear appearance and symmetrical form. A good appearance was obtained on the both sides of nostril, nasal base and the nasal sill, and the effect of preoperative design achieved. Conclusions Both sides of the nostrils size, nasal sill and shape are almost perfectly symmetrical, and the double-cut nasolabial muscle directional three-dimensional reconstruction is suitable for repairing the secondary deformity after unilateral cleft lip repair.
