Anthropometric Analysis of the Maxillary Bone and the Alar Base in Unilateral Cleft Lip With Secondary Nasal Deformity: Classification of a Piriform Margin Bony Depression

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 ...
