A New Algorithm for Secondary Repair of Unilateral Cleft Lip Nasal Deformity.

[OBJECTIVES] Following primary surgery for unilateral cleft lip palate (UCLP), cleft lip nasal deformities (CLNDs) (nasal asymmetry, collapsed nasal alae, and a widened alar base) are generally inevitable and often require secondary rhinoplasty. However, reconstructing a cleft nose with an alar tissue deficiency remains challenging for rhinoplasty surgeons.

[METHODS] The manifestations of common deformities are described herein, and a secondary rhinoplasty technique for unilateral CLNDs using a nasolabial flap (NLF) has been proposed for patients with alar tissue deficiency. Secondary rhinoplasties were performed in 12 patients with unilateral CLNDs between 2020 and 2021 using a NLF. Photogrammetric measurements were performed preoperatively and postoperatively. A total of 12 flaps were successfully transferred. Ten patients were followed up for >1 year.

[RESULTS] Significant postoperative decreases in nasal alar width were measured in both the base view (p < 0.050) and the frontal view (p < 0.050). Despite the additional facial scars that occurred in some cases, all patients were satisfied with the aesthetic effects.

[CONCLUSIONS] The NLF achieved satisfactory results in secondary rhinoplasty of unilateral CLND for patients with nasal tissue deficiencies in whom the surgeon weighed the potential benefits over postoperative scarring.
