Abstract

Background:

Although referrals for nonsyndromic frontal plagiocephaly have been increased during the past several years, successful surgical repair of unicoronal synostosis (UCS) remains a challenge for craniofacial surgeons. Most surgical techniques followed to correct supraorbital rim elevation and temporal constrictions are being noticed less and often require a secondary revision. But this new technique consists of correcting the affected ipsilateral frontal, temporal, and superior orbital rim areas in the first operation.

Methods:

From 1995 to 2016, a total of 154 cases of UCS were operated by first author. A total of 91 patients were operated with standard technique, whereas the new technique was applied on 63. Whitaker scoring system was used for evaluation of patients after surgery.

Results:

Data analysis shows a significant difference between 2 operation techniques results (P  = 0.007). None of the patients from the new technique group required revision surgery.

Conlusions:

We believe that our new technique have less invasive osteotomy on the frontal bone and no manipulation of the orbital bone, so provide sufficient bone graft and is applicable even for younger patients (<6 months).
