Surgical Hypercorrection of Trigonocephaly: Evaluation of Surgical Outcomes

A lasting correction of trigonocephaly is difficult to achieve, as a durable correction requires significant expansion to overcome galeal restriction and soft tissue recoil of the scalp. High rates of relapse have been reported throughout the literature. The specific aim of this study was to determine if the senior author's method of “hypercorrection” decreases relapse and the need for subsequent revisional surgery.


Patients who underwent operative correction of metopic craniosynostosis between 1988 and 2011 were reviewed. All patients underwent the “hypercorrection” technique performed by the senior author. Hypercorrection consisted of a fronto-orbital advancement of 2.5 to 3.5 cm and a concomitant hyperexpansion of bitemporal projection. Split cranial bone grafting ensured adequate coverage of the significantly expanded cranial vault. Only patients who had at least 5 years of follow-up were included for review of outcomes. Relapse was defined as recurrence of bitemporal constriction or lateral orbital retrusion, requiring surgical correction.


Fifty-eight patients met criteria. Mean age at the time of surgery was 11 months. Mean follow-up was 9.0 years. During this time, 2 patients exhibited relapse requiring camouflage procedures. Cranial bone defects were found in 4 patients (7%), 3 of whom underwent cranial bone grafting, while 1 underwent methylmethacrylate placement at an outside institution. One patient underwent fat grafting for areas of soft tissue irregularity. No patients exhibited persistent sequelae of hypercorrection significant enough to require repeat fronto-orbital advancement.


Surgical hypercorrection of trigonocephaly seems to minimize relapse and the need for revision in long-term follow-up and is therefore an important technique to consider.
