Tracheostomy was prevented in 25 (96%) of 26 patients, and decannulation after distraction was possible in 38 (92%) of 41 patients. Success, defined as decannulation within 1 year of the start of distraction or prevention of tracheostomy in a patient otherwise deemed as a candidate, was found in 63 (94%) of 67 patients. Oral feedings have been resumed in 61 (91%) of 67 patients.Complications observed were mostly related to pin site infections requiring antibiotics. Device failure was experienced in 2 (3%) of 66 internal devices and in 7 (10.2%) of 68 external devices.Distraction osteogenesis of the mandible provides an excellent treatment for mandibular airway obstruction in patients younger than 6 years who do not respond to conservative measures and allows for early decannulation in patients who previously underwent tracheotomy.

Classically, soft tissue repair when indicated is done before or after the skeletal mobilization especially in those cases that present midface deficiency with severe midline soft tissue restriction by scars or congenital affectation. The distraction osteogenesis method has contributed to improve substantially this problem elongating bones, muscles, and ligaments, but some situations need specific and more precise reconstruction of the subunits to gain in aesthetics. The labial-columella junction, the tip of the nose, and the more projecting point of the cheeks are one of these exigent anatomic areas, where only sophisticated reconstruction by flaps can improve facial proportions and projections.
