RESUMEN
OBJECTIVE: Evaluate treatment of patients with bilateral cleft lip operated during the last 10 years, using the methodology of Mortier and Anastassov. METHODS: A total of 84 patients were evaluated using a preoperative score assessing fissure severity and a postsurgical score assessing of uncorrected or secondary deformities. A pre- and postcorrelation analysis was performed to evaluate the gain and identify the main postoperative alterations, using Spearman's statistical test (P < 0.001). RESULTS: About 89.3% underwent surgery between 4 and 7 months. Surgical techniques used Millard 65.5% and Mulliken 34.5%. Presurgical evaluation classified fissures as mild (0%), moderate (2.4%), severe (19.1%), or very severe (78.6%). Postoperative evaluation classified results as poor (24%), satisfactory (12%), good (15, 6%), very good (34.6%), or excellent (14.3%). The postoperative changes on the lip were the notch in the vermilion and the defect in the edge of the vermilion, and in the bow of the wide cupid; in the nose, the most frequent were deficiency in the upper nasal nostril, insufficient rotation of the alar base, broad tip, and short columella; in the scar and alveolar portion, the most frequent were alveolar cleft, premaxilla protrusion, and poor scar. Spearman correlation of preoperative and postoperative was positive of 0.43. CONCLUSION: The proposed measurement method is technically simple and can be performed without equipment allowing pre- and postoperative evaluation to identify the main alterations to be corrected.
