Influence of the Number of Revision Surgeries and Nasal Symmetry After Final Rhinoplasty for Patients With Cleft Lip

Abstract

The effects of operative intervention on vertical nasal growth in patients with unilateral cleft lips (CLs) are well described. However, the factors influencing nasal symmetry have not been sufficiently evaluated. Therefore, this study aimed to study the factors that cause difficulties in obtaining nasal symmetry postoperatively in patients with CLs. We conducted a retrospective analysis using data from patients with CLs who underwent a series of treatments at Keio University Hospital from 1990 to 2000. We collected data on the patients’ sex, cleft type, number and time of revision surgery, palatal fistula incidence, and history of the pharyngeal flap and orthognathic surgery. Nasal symmetry was analyzed as the symmetrical ratio after the final touch-up surgery, and multivariate analysis was conducted using binary logistic regression to determine the factors affecting nasal symmetry. This study included 89 patients with unilateral CL. Multivariate analysis revealed that complete cleft lip and palate (P < 0.05, odds ratio = 4.37) and repeated revision surgery (P < 0.05, odds ratio = 9.28) were significant predictors of the final nasal symmetry. Our study showed that cleft type and the number of revision surgeries were identified as important factors for obtaining nasal symmetry after final touch-up rhinoplasty. Revision surgery may be necessary to relieve patients’ psychological stress due to nasal deformity, suggesting that this dilemma needs to be overcome.
