Correction of Cleft Lip Nose Deformity With Circular Shape Alar Graft and Block Costal Cartilage.

[BACKGROUND] Secondary deformities of the cleft lip and nose are mainly caused by the long period of craniofacial development and the secondary scarring. Correction of the secondary cleft lip-nose deformity is a complex process that requires both the correction of the soft tissue and skeletal support. The purpose of this study was to present our experience in correcting the secondary unilateral cleft lip-nose deformities with autologous costal cartilage.

[METHODS] A retrospective analysis of patients who underwent correction of unilateral cleft nasal deformity with simultaneous rhinoplasty by a senior surgeon from January 2015 to January 2022 was conducted. Preoperative and postoperative measurements of the columellar-labial angle and the inclination of nasal base were conducted to evaluate the surgical outcomes.

[RESULTS] A total of 54 patients were included in this study according to the inclusion criteria. The mean follow-up period was 4 years (range, 1-7 years). The mean values of the columellar-labial angle were 91.1 ± 9.2 degrees preoperatively and 101.0 ± 5.9 degrees postoperatively. The mean values of the inclination of nasal base were 4.5 ± 1.2 degrees preoperatively and 0.9 ± 0.4 degrees postoperatively. There was a considerable increase in the columellar-labial angle after the surgery (9.9 ± 6.0 degrees; P < 0.01). The inclination of nasal base decreased significantly (3.6 ± 1.1 degrees; P < 0.01).

[CONCLUSIONS] Our approach on correction the secondary clef lip nose through repositioning the muscles by Z-plasty and application of the block cartilage graft and circular shape alar graft has achieved long-term satisfactory results.
