Facial nerve dysfunction (FND) is a well-recognized, but poorly documented complication of mandibular distraction osteogenesis (MDO) for Robin sequence (RS). The authors sought to meticulously document onset, laterality, time to resolution and incidence of FND after MDO among a cohort of 23 RS patients. Our results demonstrate that among the 9 cases (39.1%) of often subtle FND, a majority were transient in nature (66.7%, n=6), occurred during the active distraction phase of MDO (88.9%, n=8), and affected the marginal mandibular nerve (100%, n=9).
