Abstract:

Separation of the complete unilateral cleft lip and maxilla maxillary lateral fissure, contralateral mandibular rotation to the contralateral, and ipsilateral maxillary hypoplasia and relocation result in increased ipsilateral nostril flats, too-wide nasal floors, a collapsed nose, and nose base and sinking external rotation deformities. Most unilateral complete cleft lips are associated with the alveolar cleft and palate, and the nasal floor completely disappears. Nasal floor repair of unilateral complete cleft lips includes orthodontic treatment before surgery and surgery of the nasal floor. Simple preoperative orthodontics can reduce the nasal floor fracture gap and shorten the operation time. The rotating propulsion method presents simple operation procedures, less postoperative bleeding, a smooth early postoperative ride, and mucosal flap at the cleft lip edge. During the repair and restoration of the nasal bottom, all exposed wounds are eliminated and all useful organizations are retained. Using the mucosal flap of the inferior turbinate to repair the nasal floor of unilateral complete cleft lips can effectively increase the amount of tissue and reduce surgical tension; furthermore, wound healing and reduced complications are ensured. The benefits of orthodontic treatment before surgery require further study in China, and the therapeutic effects obtained from such a procedure are not stable. Therefore, new approaches should be continually explored to compensate for the deficiencies of traditional methods.

Key words: unilateral complete cleft lip, preoperative orthodontic, nasal floor repair
