Results of Lip Adhesion in Wide Unilateral Complete Cleft Lip Patients.

Long-term follow-up results of many surgical techniques for lip adhesion are unavailable. Thus, we report the surgical results of patients who underwent lip adhesions performed by a single surgeon. We retrospectively analyzed two-dimensional photographs of 29 patients aged 1 year who underwent lip adhesion and definite lip repair. Among these patients, we analyzed the photographs of 20 patients aged 6 years who underwent secondary rhinoplasty. The ratio of the cleft side length to the noncleft side length was calculated. Only the upper lip length in the photographs of 1-year-olds was measured; both the upper lip and nose lengths were measured in the photographs of 6-year-olds. Lip width, vermilion height, and medial lip height on the cleft and non-cleft sides of 1-year-olds were not significantly different; the alar base width ratio was 1.17 ± 0.15, and the lateral lip height ratio was 0.91 ± 0.09 (P < 0.001). No significant differences were observed in lip width and vermilion height between the cleft and non-cleft sides of the upper lip of 6-year-olds; the alar base width ratio was 1.22 ± 0.16, medial lip height ratio was 1.11 ± 0.11, and lateral lip height ratio was 0.89 ± 0.09 (P < 0.05). There were no significant differences in the alar projection and nasal dome height on the cleft side of the nose; the nostril height and width ratios were 0.82 ± 0.11 and 1.31 ± 0.21 (P < 0.001), respectively. These consecutively performed lip adhesions for patients with wide unilateral complete cleft lip resulted in excellent long-term results. Therefore, lip adhesion for wide unilateral complete cleft lip is a reasonable alternative to presurgical molding.
