Area of Science:

  • Oral and Maxillofacial Surgery
  • Orthodontics
  • Regenerative Medicine

Background:

  • Conventional bilateral sagittal split osteotomy is a standard procedure for mandibular lengthening.
  • Distraction osteogenesis presents a potential alternative with different complication profiles.

Purpose of the Study:

  • To evaluate distraction osteogenesis as an alternative to conventional bilateral sagittal split osteotomy.
  • To retrospectively assess intraoperative, intradistraction, and postdistraction complications.

Main Methods:

  • Seventy patients (mean age 14.2 years) underwent mandibular lengthening using distraction osteogenesis.
  • Intraoral distraction devices were placed, with a distraction rate of 1 mm/day.
  • Complications were recorded throughout all treatment phases.

Main Results:

  • A total of 28 complications (40%) were recorded, with 14.3% related to technique or device early in the learning period.
  • Severe complications occurred in 8.6% of patients, requiring rehospitalization in 7.1%.
  • Infection rate was 7.1%, and prolonged sensory loss occurred in 4.3%.

Conclusions:

  • Distraction osteogenesis is a safe and predictable method for mandibular lengthening with a low incidence of major complications.
  • The rates of infection and inferior alveolar nerve damage are low (2.1%).
  • Optimal patient and parental compliance is essential for successful treatment outcomes.
