BACKGROUND: Achieving symmetry in secondary cleft rhinoplasty is challenging even for the most skilled surgeon. The authors present their technique and outcomes of using a circumferential alar rim graft to relocate the cleft-sided anterior ala superiorly and anteriorly. The graft, under tension, is anchored to the septum at one end and the intermediate crus at the other, exerting an upward and anteriorly projected force.
METHODS: Adult patients with unilateral cleft lip and palate who underwent secondary cleft rhinoplasty between 2013 and 2022, using the circumferential alar rim graft (CARG) technique, were included. Standardized photographs were used to obtain morphometric measurements. Ratios of cleft side to non-cleft side nostril height, width, and area, as well as tip projection, were compared preoperatively and postoperatively. Wilcoxon signed-rank test evaluated statistically significant differences between the measurements.
RESULTS: Twenty-seven patients were included, with a mean age of 26.9 years (range 19-42). Most were female (n=18), with left-sided clefts (n=20). Nostril height symmetry, expressed as a ratio of cleft side over the non-cleft side (with 1 being perfect symmetry), improved significantly by 10% ( P <0.001). Nostril width symmetry improved significantly by 22% ( P =0.012), and nostril area symmetry improved significantly by 21% ( P =0.008). When preoperative and postoperative subnasale-pronasale over inter-alar width ratios were compared, tip projection was found to increase significantly by 10% ( P =0.029). Five CARG-related complications occurred, including 2 graft detachments and 1 graft fracture.
CONCLUSIONS: Using a circumferential alar rim graft in secondary cleft rhinoplasty significantly improved nasal symmetry in terms of nostril height and area.
