Rigid External Distraction Osteogenesis for a Patient With Maxillary Hypoplasia and Oligodontia

Distraction osteogenesis is one of the latest treatment modalities in correcting skeletal discrepancies in the craniofacial region. Maxillary retrusion is a common problem when deformity of the face is concerned, especially in cleft lip and palate patients. Distraction osteogenesis utilizing internal or external has an enormous role in future as an alternative method of skeletal correction in patients with severe maxillary hypoplasia. In addition, periodontal rehabilitation in these patients is of utmost importance especially at the end of treatment. This case report presents one such case of severe maxillary retrusion treated successfully by distraction osteogenesis. JMS 2012;15(1):78-81.

Objective: Distraction osteogenesis is a well-accepted technique in the treatment of patients with hypoplastic craniofacial components. Complications of distraction osteogenesis are well described in the literature. We describe a complication of using an external distraction device in a 9-year-old girl with Pfeiffer. Intervention and Results: A modified Lefort III osteotomy was performed for maxillary hypoplasia with application of an external distraction halo device by a pediatric neurosurgeon. A postoperative computed tomography (CT) scan showed 0.5-cm skull penetration of the cranial pins. The pins were repositioned and the patient was followed up on a regular basis until discharge from the hospital. At 3-week follow-up, a CT scan of the head showed migration of the pins 1.5 cm intracranially. The halo was removed and repositioned at a different site. No detectable neurological sequelae from the pin penetration were noted. The patient developed cellulitis at the site of the penetration and was admitted to the hospital for a course of intravenous antibiotics. There were no other complications, and the rest of her treatment course proceeded as planned. A review of the literature on complications of halo usage as well as suggestions for their management in association with distraction osteogenesis is described.
