Clinical characteristics and surgical outcomes of bad scar revision after congenital unilateral cleft lip surgery according to modified Millard’s technique

Abstract

ABSTRACT Objectives: To study the clinical characteristics and surgical results of bad scar revision after congenital unilateral cleft lip plastic surgery according to the modified Millard’s technique. Methods: A prospective descriptive study with clinical intervention was carried out on 36 patients who had congenital unilateral cleft lip surgery according to Millard’s technique with bad scars, deformed lips and nose. They had second - phase surgery to revise these defects at Odonto - Stomatology Center, Hue Central Hospital from April 2021 to April 2023. Results: Bad scar characteristics: Red lips: Keloid accounted for 27.8%; V-shaped notch accounted for 36.1%, one - sided thick lip accounted for 11.1%, one - sided thin lips accounted for 8.3%, lip contour deviation accounted for 69.4%; Lip skin deformity: Too short accounted for 25.0%, Deficiency of orbicularis obis accounted for 36.1%; Incision scars: Good scars accounted for 11.1%, Traction rate 86.1%, Keloid rate 2.8%; Nasal deformity: Too short nose pillar at a rate of 30.6%, Deviated nasal septum 41.7%, wide nostrils 97.2%, Little degree of alar rolling accounted for 47.2%, low alar at 63 .9%, hypoplastic and flat alars accounted for 11.1%. Results of surgery to revise bad scars: Healing results after 7 days: Good 94.4% Hematoma, bruise accounted for 5.6%; Results after 3 - 6 months: Excellent: 72.2% Very Good: 22.2%, Good 2.8%, Acceptable 2.8%. Conclusion: Surgery to revise bad scars and lip - nose deformities by the modified Millard’s technique brings good results for patients.
