Three-Dimensional Analysis of Nasal Symmetry following Primary Correction of Unilateral Cleft Lip Nasal Deformity:

2017 
Objective:  To evaluate nasal symmetry using three-dimensional photogrammetry following primary tip rhinoplasty with or without an internal splint in patients with unilateral complete cleft lip/palate. Design:  We captured three-dimensional images of patients with unilateral complete cleft lip/palate who underwent nasolabial repair by rotation-advancement of the lip and primary tip rhinoplasty, either with or without an internal resorbable splint, and normal control subjects. We assessed nasal symmetry by identifying the plane of maximum symmetry and the root-mean-square deviation between native and reflected surfaces. Patients/Participants:  We imaged 38 controls and 38 subjects with repaired unilateral complete cleft lip/palate (20 with, 18 without an internal splint). Results:  Nasal asymmetry root-mean-square deviation clustered between 0.19 and 0.50 mm (median = 0.24 ± 0.08 mm) for controls; whereas, those with repaired unilateral complete cleft lip/palate ranged from 0.4 to 1.5 mm (median = 0.75 ± 0...
