Abstract

PURPOSE
Cleft lip and palate is one of the most frequent hereditary deformities of the maxillofacial region which can arise in facial and jaw abnormalities as well as malocclusion and speech problems. In particular, unilateral cleft lip and palate is characterized by midface deformity resulting in maxillary anterior nasal septal deviation and nasal deformity. The aim of this study is to analyze the facial deformity of untreated unilateral cleft lip patients for contribution to primary cheiloplasty.
METHODS
Thirty-three patients with unilateral cleft lip and palate were impressioned before operation and facial casts were made. The casts were classified into complete cleft lip and incomplete cleft lip groups and each group were classified into affected side and normal side. Anthropometric reference points and lines were setted up and analysis between points and lines were made.
RESULTS
AND CONCLUSION: The obtained results were as follows: 1.The intercanthal width had no significant difference between the incomplete and complete cleft lip groups. 2.Cleft width and alar base width were greater in the complete group, and nasal tip protrusion was greater in the incomplete group. 3.Involved alar width and nostril width were greater in the complete group and in both complete and incomplete groups, involved alar width and nostril width were greater than the non-involved side. 4.The lateral deviation of the subnasale was greater in the complete group in both involved and non-involved sides. 5.The nasal laterale was placed inferiorly in both cleft groups. 6.The subnasale was deviated to the non-involved side in both cleft groups. 7.The nose tip was deviated to the non-involved side in both cleft groups and had greater lateral deviation in the complete cleft group. 8.The midpoint of cupid's bow had no vertical difference between complete and incomplete groups, but had a greater lateral deviation in the complete group. 9.In the complete cleft group, correlation between differences in cleft width and nostril width and columella height difference were obtained.
