dc.descriptionA series of skeletal and dentoalveolar/occlusal criteria were proposed for choosing the treatment modality for the management of midface hypoplasia in cleft lip/palate patients, focusing on functional improvement, aesthetics, and minimizing the risk of recurrence and secondary alterations. For which, 42 patients with nonsyndromic cleft lip/palate, all with previous primary lip/palate surgeries and without previous osteotomies, were analyzed. Orthognathic surgery (OS) (n = 24) and maxillary distraction osteogenesis (n = 18) with anterior segmental osteotomies (segmental distraction osteogenesis [SD]), alveolar transport disc (TD), and midface total distraction osteogenesis (TDO) by modified Le Fort III osteotomy was done. The average of maxillary advancement for OS was 5.58 ± 0.83 mm, for SD 9.4 ± 0.89 mm, for TD 8.00 ± 1.00 mm, and for TDO was 8.13 ± 1.55 mm. In the presence of infraorbital and/or zygomatic hypoplasia, TDO was performed using skeletal anchorage, with the requirement of occlusal stability in dental cast in occlusion. In short maxillary arch without dental cast feasibility in occlusion, hypodontia/agenesis or absence of premaxilla, TD and SD was performed. There was only 1 mm of recurrence in 1 patient of each group. Changes in speech were detected in 2 patients in the OS group (8.3%). Orthognathic surgery can be indicated for advancements ≤7 mm not requiring orbito-zygomatic advancement, whereas distraction osteogenesis can be indicated for advances >8 mm with or without the need for orbito-zygomatic advancement, in addition with other dentoalveolar factors and velopharyngeal function.eng
