Background: The authors performed a critical literature review to find evidence of the long-term stability after early distraction osteogenesis of the mandible in patients with hemifacial microsomia.

Methods: The PubMed, Cochrane, MEDLINE, EMBASE, CENTRAL, and CINAHL databases were searched systematically for studies performed between 2002 and 2008. Abstracts from the 89 relevant articles were reviewed for evidence.

Results: Thirteen articles met the inclusion criteria. Data were tabulated with respect to the length of follow-up, number of patients, age group, Pruzansky-Kaban classification of the patients, methods of analysis and validation, and level of evidence. Methods for long-term follow-up studies were not standardized, and no objective studies have been published on stability after growth cessation.

Conclusions: Thus far, no randomized controlled trials on early distraction osteogenesis in hemifacial microsomia patients have been published. The authors conclude that there is a lack of statistical evidence to support the use of early distraction osteogenesis for correcting hemifacial microsomia as a single treatment modality. The results call into question its rationale.
