Longitudinal Anatomic Analysis of Primary Cleft Lip Rhinoplasty Outcomes.

The unilateral cleft lip deformity is associated with nasal deformities with secondary functional and aesthetic challenges. Compare the change in nasal symmetry before and incrementally after primary endonasal cleft rhinoplasty concurrent with lip repair. This is a retrospective chart review of infants undergoing unilateral cleft lip repair. Data collection included demographics, surgical history, and pre- and postoperative alar and nostril photographs analyzed with Image J. Statistical analysis was done using linear and multivariable mixed effect models. Twenty-two patients with a near even gender distribution (46% female) and primarily left-sided cleft lips underwent unilateral lip repair at a mean age of 3.9 months (median 3.0, range 2-12). Mean pre- and postoperative alar symmetry ratios were 0.099 (standard error [SE] 0.0019) and -0.0012 (SE 0.0179), with zero representing perfect symmetry and negative values indicating overcorrection. These values at 1, 2-4, 5-7, 8-12, 13-24, and 25+ months were 0.026, 0.050, 0.046, 0.052, 0.049, and 0.052 (SE range: 0.0015-0.0096), respectively, demonstrating stability of the alar symmetry 4 months postrepair. In this study, patients who underwent an overcorrective primary cleft rhinoplasty concurrent with lip repair had an initial regression of symmetry within the first 4 months postoperatively, followed by observed stabilization.
