Trigonocephaly: refinements in reconstruction. Experience with 33 patients.

Thirty-three consecutive patients with metopic synostosis treated between January of 1980 and June of 1984 are presented. All patients underwent craniofacial reconstruction by an interdisciplinary team utilizing a detailed remodeling of the supraorbital rims and forehead. Advantages of the current modifications are discussed, as well as an analysis of the results. We believe this represents a significant advance over previous methods not only because of the superior cosmetic results achieved, but also because of its safety and reproducibility. Reoperation rate was less than 10 percent overall and was necessary only in patients with complex cranial vault abnormalities. Mean follow-up was 22.8 months, with no deaths, infections, or damage to visual or cerebral function. Postoperative head circumference demonstrated an immediate increase followed by a normal growth curve.
