Objective: The asymmetry of a retrusive cleft-side ala positioned posterior, lateral, and inferior relative to the noncleft ala is exacerbated by ipsilateral deficiency of the pyriform aperture. We describe use of pyriform costal cartilage grafts for enhanced structural foundation and alar symmetry in secondary cleft rhinoplasty. Design: Retrospective case series. Patients: All pyriform aperture paranasal augmentation secondary cleft rhinoplasty cases performed between May 2013 and February 2018 were included. Clinical photos were analyzed, and these results are provided in addition to a detailed description of the augmentation technique. Results: Twelve total cleft patients, 10 (83.3%) unilateral cleft lip and palate, 1 (8.3%) unilateral cleft lip, and 1 cleft palate (8.3%) were included. Age averaged 18.6 ± 6.0 years with 3 (25.0%) males and 9 (75.0%) females. Costal cartilage grafting to the pyriform aperture through the gingivobuccal sulcus was used to reposition the alar base and nasal sill to a more anatomic anterior position, thereby enhancing symmetry in secondary cleft rhinoplasty. Average rib graft donor site incision was 2.5 cm. Follow-up ranged from 3.2 to 48.2 months, average 15.3 ± 14.4 months. No complications related to the pyriform cartilage graft were observed, other than one minor intraoperative breach of parietal pleura. Conclusions: We observed improvement in the anatomic contour of the cleft-side ala with costal cartilage grafting to the pyriform rim. This resulted in improved cleft-side alar form and thus overall alar symmetry. These results were obtained consistently, without significant complications. This technique is safe and provides a powerful tool to reposition the ala in secondary cleft rhinoplasty. Further studies will quantify the enhancement in nasal base symmetry. [ABSTRACT FROM AUTHOR]
