ABSTRACT
ABSTRACT In unilateral cleft lip and palate patients, the alar base is displaced inferoposterolaterally due to the depression of the pyriform aperture in the cleft side, and the drooping of the nostril rim is provoked by displacement of the alar base. This study was conducted between May 1998 and December 2012. In total, 82 patients with secondary unilateral cleft lip nasal deformities were treated using alar base augmentation. The patients were divided into two groups according to the degree of their preoperative alar base asymmetry. Patients with alar base asymmetry <3âmm were treated with a soft tissue augmentation procedure. Those with alar base asymmetry >3 and <6âmm were treated with a bony augmentation procedure. Soft tissue augmentation was conducted in 42 patients, and bony augmentation was conducted in 40 patients. In the soft tissue augmentation group, the degree of alar base asymmetry was improved from 2.42â±â0.38âmm preoperatively to 0.45â±â0.21âmm postoperatively (Pâ <â0.05). In the bony augmentation group, the degree of alar base asymmetry was improved from 4.33â±â0.50âmm preoperatively to 0.81â±â0.20âmm postoperatively (Pâ <â0.05). In the amount of alar base augmentation, there were statistically significant differences between the soft tissue augmentation group and the bony augmentation group (Pâ <â0.05). This clinical study shows that secondary cleft lip nasal deformities can be corrected with alar base augmentation using soft tissue and bony augmentation and that these procedures can provide reliable, satisfactory, and safe clinical outcomes.
