OBJECTIVES: Comparison of nasal asymmetry between unilateral cleft lip and palate (UCLP) patients with and without nasal correction at primary repair. Assessment of the value of Symnose as a routine research tool.
PARTICIPANTS: 75 ten-year-old UCLP patients who underwent primary lip repair by one of two techniques: classical Millard with primary nasal correction (n = 30) or modified Millard without nasal correction (n = 45). Control group of ten-year-old school children (n = 45).
METHODS: Nasal asymmetry of participants was measured from facial photographs taken in two views: frontal and basal. The Symnose computer program was used to calculate asymmetry for three parameters: front perimeter (FP), base perimeter (BP) and nostrils (N). Total asymmetry was also calculated. Each image was traced on three separate occasions and a mean of the three measurements was calculated.
RESULTS: BP, N and total asymmetry were significantly greater in UCLP patients without nasal correction compared to both controls and patients with correction (BP = 12.73% v 4.90% v 6.75%, N = 47.73% v 15.83% v 30.75%, total = 81.87% v 46.43% v 54.68%, p ≤ 0.001). FP asymmetry was significantly greater in controls than all UCLP patients (22.87% v. 18.18% and 15.07%, p = 0.001 and p = 0.008). BP measurements have a higher degree of repeatability than FP and N (Coefficient of repeatability = 5.99, 17.02 and 16.47, respectively).
CONCLUSIONS: Primary nasal correction produces greater nasal symmetry during childhood from the basal view. Symnose is a simple method of objectively measuring asymmetry in UCLP, however improvements are required before it can be considered a useful research tool.
