Complications in bilateral mandibular distraction osteogenesis using internal devices.

摘要: Abstract Objective We sought to evaluate the possibility of distraction osteogenesis as an alternative conventional bilateral sagittal split osteotomy. Complications (intraoperative, intradistraction, and postdistraction) were evaluated retrospectively. Study design Seventy consecutive patients (40 males 30 females, 11.2-37.3 years old; mean, 14.2 years) underwent lengthen mandible. The surgical procedure was carried out with patient under general anesthesia. After osteotomy performed, 2 intraoral monodirectional devices placed on mandibular cortex in third molar region. rate 1 mm/day. different complications encountered during all phases recorded. Results A total 28 (40%) In 10 (14.3%), technique- or device-related, both, occurred early learning period. Five (7.1%) had infection occur, 3 (4.3%) prolonged sensory loss distribution alveolar nerve. Severe 6 (8.6%). Rehospitalization necessary 5 (7.1%), 4 whom (5.7% series) required further surgery Conclusion Distraction can be considered a safe predictable for lengthening mandible, low incidence major complications. damage inferior nerve (2.1%) are low. Compliance both parents whole treatment period is utmost importance.
