Infant Mandibular Distraction for Upper Airway Obstruction: A Clinical Audit

Area of Science:

• Craniofacial surgery
• Pediatric otolaryngology
• Pediatric plastic surgery

Background:

• Mandibular distraction osteogenesis (MDO) is a key treatment for micrognathic infants with upper airway obstruction (UAO).
• While effective for short-term relief, MDO involves significant surgical risks.
• This study evaluates a 12-year cohort of infants treated with MDO.

Purpose of the Study:

• To assess the long-term outcomes of MDO in infants with micrognathia and UAO.
• To evaluate dental anomalies, nerve injuries, and scar cosmesis post-MDO.
• To contribute to the evidence base for MDO in pediatric UAO management.

Main Methods:

• Retrospective chart review of children under 5 undergoing MDO (2000-2012).
• Clinical review focusing on dental anomalies, nerve deficits, and scar appearance.
• Analysis of airway, feeding, and tracheostomy status.

Main Results:

• 73 children underwent MDO, with earlier intervention for non-syndromic cases.
• 56% of previously tracheostomy-dependent infants were decannulated within 1 year.
• 97% of non-syndromic infants achieved oral feeding by 12 months post-op; dental defects noted, but low neurosensory deficits and good scar cosmesis.

Conclusions:

• MDO offers significant benefits for micrognathic infants with UAO, improving airway and feeding.
• Long-term outcomes include a low rate of complications like nerve injury and good cosmetic results.
• Further evidence supports MDO as a valuable treatment option for this population.
