ABSTRACT
The prolabium located centrally is devoid of muscle and consists of skin, vermillion and oral mucosa. Lip adhesion is a surgical procedure which allows mobilization of the nasal layer and closure of the lateral segment margins with the prolabium without mobilization and anastomosis of the orbicularis oris muscle. Closure of bilateral cleft lip is performed in three layers. The ideal age of repair of the bilateral cleft lip is 3 months, but patients may present at any age in less informed societies. The nasal layer is closed in continuity with the closure of the premaxillary nasal mucosa which was performed earlier. Once the nasal layer closure is complete, the mucosa on the inner aspect of the upper lip on either side is sutured to the prolabial mucosa to form the sulcus of the oral cavity. Closure is obtained using 4/0 Vicryl sutures.
