The Role of Nasal Sill Correction in Secondary Cleft Rhinoplasty

Abstract

BackgroundEvaluating outcomes after cleft rhinoplasty can be challenging because of the lack of objective measures that would lead to a more desirable outcome.MethodsThis study is a 10-year retrospective review of 30 consecutive patients who underwent secondary unilateral cleft rhinoplasty performed by a single surgeon. Subjective ratings were made using the Unilateral Cleft Lip Surgical Outcomes Evaluation (UCL SOE), which rates 4 components (nose, cupid's bow, lateral lip, and free vermillion) with a score of 0 to 2. Multiple anthropometric measurements (nostril height ratio, width ratio, medial ¼ height ratio, sill ratio, nostril area ratio, columellar angle, tip projection ratio, and nasolabial angle) were taken using a free National Institutes of Health program, ImageJ. Standardized photographs were compared at T0 (preoperatively), T1 (<6 weeks postoperatively), and T2 (>6 weeks postoperatively).ResultsThere were 30 patients who met our inclusion criteria: 10 males (66.7%) and 20 females (66.7%). Of these patients, 26 (86.7%) had a complete cleft lip and 4 (13.3%) had an incomplete cleft lip. The patients' average age at time of surgery was 16.2 years with a mean follow-up of 17.9 months. Subjective scores in both nasal and overall UCL SOE ratings improved from T0 to T1, 0.7 to 1.2 (P ≤ 0.001) and 3.6 to 4.7 (P ≤ 0.001), respectively. Visual analog scores in nasal and overall UCL SOE ratings improved between T0 and T2, 0.7 to 0.9 (P = 0.023) and 3.6 to 4.8 (P = 0.002), respectively. Of all the objective measures, nasal sill ratio and cleft height to width ratio correlated with improved subjective ratings across multiple time points.ConclusionsOur study shows that objective measures such as nasal sill and nostril shape (cleft height to width ratio) correlate with improved subjective visual analog scale using the UCL SOE. The nasal sill is an often overlooked, yet essential, part of creating an aesthetically pleasing nose during cleft rhinoplasty.
