Abstract
Unicoronal craniosynostosis is notoriously difficult to treat, with long-term studies demonstrating high rates of relapse and the need for reoperation using open fronto-orbital advancement. Applying the principles of distraction osteogenesis to cranial vault remodeling has demonstrated promising short-term results that compare favorably with traditional methods, with simultaneous correction of both frontofacial and endocranial morphology, along with significant increases in intracranial volume. Here, the authors demonstrate their technique for rotation flap distraction osteogenesis in the treatment of unicoronal synostosis and provide case examples.The video can be found here: https://vimeo.com/519505008.

Unicoronal craniosynostosis is one of the most difficult types of craniosynostosis to treat due to its relatively high incidence of relapse, requiring reoperation in over 20% of patients in some case series

Summary
This video describes our technique for creation of a bony rotational flap for treatment of unicoronal synostosis via distraction osteogenesis.0:58 Patient Example.Here we see an example of a 10-month-old boy presenting with left unicoronal synostosis. Traditional techniques involving removal of the frontal bone and orbital bandeau, ex situ remodeling, and overcorrection have not successfully avoided relapse of the deformity over time. This video describes our technique for creation of a bony rotational flap for treatment of unicoronal synostosis via distraction osteogenesis. This mark is biased posteriorly on the affected side to compensate for anticipated anterior migration of the incision with distraction.
