Repair method of cleft lip and palate: There are many symptoms of cleft lip. According to these different symptoms, we need appropriate methods to repair it, so as to get the best repair effect. Common symptoms include unilateral secondary cleft lip, bilateral secondary cleft lip, unilateral cleft lip deformity and secondary deformity. Unilateral secondary cleft lip can be repaired by rotating propulsion, and orbicularis oris muscle can be repaired in layers, without affecting the main natural structure of the lip, which can ensure that the lower tissue of the upper lip is relaxed enough, remove the scar of the first-stage operation and repair the deformed lip red at the same time. Bilateral secondary cleft lip can be repaired by comprehensive cosmetic surgery. The comprehensive cosmetic repair of bilateral cleft lip will not be too long or too tight, and there will be no problems such as upper lip protrusion and lower lip contraction. In the comprehensive cosmetic repair of bilateral cleft lip, the labial red inlay and suture are very fine, and the upper lip is very natural after operation. For unilateral cleft lip deformity, the columella, alar base, nasal septum and tip can be designed and shaped comprehensively with autologous cartilage and prosthetic materials, and the nose shape can be basically close to normal after operation.
