[Evaluation of the effect of repairing unilateral cleft lip nose deformity with autogenous concha cartilage].

Purpose: To explore the effect of nasal deformity correction after unilateral cleft lip repair with autogenous concha cartilage transplantation.

Methods: Thirteen patients with nasal deformity after unilateral cleft lip surgery were collected, who were treated with autogenous concha cartilage and nasal septum deviation correction at the same time. Their chin-lifting photos were taken before operation, five days, one month and six months after operation. The nasal morphology was evaluated by subjective evaluation and objective measurement, and statistical analysis was performed using SPSS 21.0 software package.

Results: Subjective evaluation showed that there was significant difference in nasal morphology between prior to operation and 5 days postoperatively (P=0.000), but there was no significant difference between 5 days postoperatively and 1 month and 6 months postoperatively(P=0.110, 0.053). In objective measurement, there was no significant difference in the symmetry rate of nasal tip between prior to operation and 5 days, 1 month and 6 months after operation(P=0.051, 0.136, 0.204), but there was significant difference in the symmetry rate of nasal base, nasal columella, extranasal convex angle and nasal alar base inclination angle between prior to operation and 5 days postoperatively(P=0.000, 0.000, 0.000, 0.000). However, there was no significant difference in symmetry rate of the above four indexes between 5 days after operation and 1 month and 6 months after operation(P＞0.05).

Conclusions: Autogenous concha cartilage transplantation can effectively improve the symmetry of nasal floor, columella and alar after operation, and the effect is stable half a year after operation.
