Trigonocephaly accounts for approximately 10% of all craniosynostosis. Severe trigonocephaly results in a triangular-shaped forehead, superior-lateral orbital depression, hypotelorism, and compensatory occipital-parietal calvarial changes. Radiographic findings include ovoid orbits with parallel medial borders, thickened keel-shaped frontal bone, small ethmoid sinuses, and a short anterior cranial fossa with pitched sphenoid wings. Our experience with 50 infantile cases of severe nonsyndromic trigonocephaly patients treated from 1987 to 2005 is clinically reviewed to assess long-term growth based on a standardized operative technique. The average age of the patients at surgery was 6 months and the mean follow-up was 12 years. Our complication rate was 2%; the reoperative rate was 12%. The use of resorbable rigid plate fixation combined with alloplastic augmentation has improved the cosmetic outcome in patients treated since 1996 and reduced the reoperative rate.
