Background:
Because primary nasal correction by the time of lip repair has been incorporated into the treatment approach, many patients have benefitted from this combined procedure. However, primary nasal correction cannot guarantee an excellent result. Although overcorrection has been mentioned as a treatment rationale of the unilateral cleft lip nasal deformity, a detailed approach and quantitative evidence of the rationale are rare. This study evaluates whether overcorrection in the primary repair results in a quantitative improvement in nasal appearance.
Patients And Methods:
In this retrospective study, the inclusion criteria were patients with complete unilateral cleft lip and palate who underwent primary lip and nose repair by the age of 3 to 4 months. Primary nasal overcorrection was achieved by application of muscle to septal base suture, alar cinching suture and Tajima reversed U incision method. Patients were further divided into an overcorrected (n = 19) and nonovercorrected group (n = 19). The following parameters were identified on basilar photos of all patients taken at least 12 months after repair, ratios of cleft to noncleft side in each patient were taken and the mean for each parameter calculated: Ac angle (ACA/ACA'), alar height (AH/AH'), alar width (AW/AW'), nostril height (NH/NH`), nostril width (NW/NW'), and columellar deviation from the midline (CD/NW). The means of the overcorrected and nonovercorrected groups were then compared using the t test.
Results:
From all investigated measuremens, Alar height (AH/AH': overcorrected, 0.983 to nonovercorrected, 0.941; P = 0.03) and nostril height ratio (NH/NH') (NH/NH': covercorrected, 0.897 to nonovercorrected, 0.680; P = 0.003) showed statistically significant differences favoring the overcorrected group at least 12 months after surgery.
Conclusions:
Primary nasal overcorrection including muscle to columella base suture, alar cinch suture, and Tajima method resulted in quantitatively more long-term symmetric alae and nostril height compared to nonovercorrected patients.
