AIM: The aim of the study is to review the articles in literature comparing distraction osteogenesis and conventional orthognathic surgery in cleft maxillary hypoplasia.

MATERIALS & METHODS - A  total of 2 articles were selected for this literature review after searching  in PUBMED, COCHRANE and  Google scholar. The inclusion criteria , exclusion criteria and outcome measures were studies for both the study and the results were discussed.

RESULTS - According to Adi Rachmiel et al., one stage orthognathic surgery is preferred in mild maxillary deficiency whereas distraction techniques is preferred in patients requiring moderate to large advancements with significant structural deficiencies of maxilla. According to Chua et al., it was concluded that distraction osteogenesis has no advantage over conventional orthognathic surgery for the purpose of preventing velopharyngeal incompetence and speech disturbances. Future studies should be done to compare distraction osteogenesis and orthognathic with more outcome measures and with longer follow up rates.
