Abstract
Objectives
This study was conducted to measure the soft tissue of the alar base and the piriform aperture area of the maxillary bone of unilateral cleft lips with secondary nasal deformities when secondary operation are necessary to classify the alar base depression and to provide a clinical reference for the second surgery.
Methods
Twenty-six patients with unilateral cleft lip with secondary nasal deformity were treated at the Department of Oral and Maxillofacial Surgery, School of Stomatology, China Medial University. Nose data were attained preoperatively and postoperatively. Correlations were made between the soft tissue and the bony depression and patient satisfaction with the nasi basis. Classifications were then made based on these data.
Results
When the distance discrepancy of the bilateral piriform aperture depression was less than 4.5 mm, we obtained a fine appearance for the nose by repairing only the soft tissues. When it was more than 5 mm, we had to combine repair of the soft tissue with a bone graft or the restitution of the alveolar cleft. When the distance was between 4.5 mm and 5 mm, the surgeon considered both the wishes of the patient and the clinic's standard procedure.
Conclusions
For patients with cleft lips and palates, the bony depression was not the only factor that resulted in postoperative alar depression. Anthropometry of the nose prior to surgery was important for choosing the methods that would yield satisfactory results.
