ANTERIOR MAXILLARY DISTRACTION: A VIABLE SURGICAL ALTERNATIVE TO CONVENTIONAL ORTHOGNATHIC SURGERY OR TOTAL MAXILLARY DISTRACTION OSTEOGENESIS FOR MILD TO MODERATE CLEFT MAXILLARY HYPOPLASIA
Abstract
Although cleft maxillary hypoplasia can be effectively managed using either Lefort 1 maxillary advancement with conventional orthognathic surgery or with total maxillary distraction osteogenesis, yet many studies have demonstrated velopharyngeal closure problems and distortion of speech post-surgery with either of the two modalities. Further more conventional orthognathic surgery is riddled with high relapse rates and requires completion of growth to perform the surgery. Therefore, the need for a surgical procedure that is not only stable but also has minimal or no effect on velopharyngeal function and speech becomes prudent. Anterior maxillary distraction is one such modality of treating cleft maxillary hypoplasia. This article presents a short comprehensive review about anterior maxillary distraction including the merits and demerits of the technique.
