Abstract :

Cleft lip and palate are commonly noticed congenital deformities in the orofacial area causing several functional and esthetic problems. The management of maxillary retrusion in cleft lip and palate patients is performed using Le Fort I advancement or distraction osteogenesis using an external or an internal device. Distraction mostly involves movement of the entire maxilla at the Le Fort I level and is characterized by a higher relapse. Distraction of the anterior maxilla using a tooth–borne palatal distractor similar to the one proposed by Gunaseelan et al (J Oral Maxillofac Surg 65:1044, 2007) has previously yielded stable results. A modification of this technique by placing the distractor postoperatively after performing the osteotomy cut was followed. The main advantage of this modification is that more control over the vector can be achieved and chances of cement failure caused by contamination and an inability to achieve isolation is drastically decreased.
