“…Trigonocephaly varies in severity and may be difficult to characterize [Oi and Matsumoto, 1987]. Uncomplicated trigonocephaly comprises orbital hypotelorism, ethmoidal hypoplasia and a symmetric, keel‐shaped frontal bone malformation [Zanini et al, 1992]. The skull tends to have a triangular shape due to the temporal depression, increased parietal diameter and forehead prominence [Zanini et al, 1992].…”

“…The skull tends to have a triangular shape due to the temporal depression, increased parietal diameter and forehead prominence [Zanini et al, 1992]. Trigonocephaly can be isolated, associated with other congenital anomalies such as holoprosencephaly, or occur as part of a multiple malformation syndrome [Zanini et al, 1992]. The latter category includes teratogenically‐induced disorders such as valproic acid embryopathy [Lajeunie et al, 1998], chromosome abnormalities, such as deletion of 9p [Alfi et al, 1976], deletion of 11q [Cassidy et al, 1977], deletion of 13q [Orbeli et al, 1971] and duplication of 13q [Schinzel et al, 1976], and three previously described malformation syndromes: Frydman, Opitz C and Say‐Meyer syndromes.…”

Fronto-Ocular syndrome: Newly recognized trigonocephaly syndrome

We describe an apparently unique disorder, Fronto-Ocular syndrome, present in a mother and her two daughters, and comprising trigonocephaly due to coronal and metopic craniosynostosis, ocular hypotelorism, ocular proptosis and ptosis, epicanthal folds, hypoplastic supraorbital ridges, elevated nasal bridge, thin philtrum, high-arched palate and a narrow bifrontal region. Both daughters have glabellar capillary hemangiomas, a congenital heart defect and mild developmental disabilities. Review of the literature failed to disclose any syndrome with similar findings. It is likely that this disorder represents an autosomal dominant condition, that arose as a new mutation in the mother. Mutational analysis of fibroblast growth factor receptor (FGFR) 1 and FGFR2 failed to identify the molecular basis of the disorder.

“…Several surgical techniques have been suggested for the treatment of simple trigonocephaly (1,5,6,13,16) including nasofrontal osteotomies, and interpositional grafts or step osteotomies for correction of the associated orbital hypotelorism (12).…”

“…Surgical correction of trigonocephaly is advocated in patients with moderate or severe deformities, and several techniques have been suggested (1,5,6,13,14,16). McCarthy et al (12) proposed a nasofrontal osteotomy with an interpositional bone graft or a step osteotomy for the correction of hypotelorism.…”

Clinically diagnosed trigonocephaly have been treated by a standard surgical technique developed at Göteborg University Craniofacial Unit. To evaluate the technique we designed a study to include both subjective and objective assessments. Of 30 patients operated on between 1988-1997, 15 patients with at least three years postoperative follow-up have been included. An evaluation of the surgical outcome of the bitemporal width, the forehead contour, and the intercanthal distance was made both subjectively using a visual analogue scale (VAS) and objectively with analyses of cephalograms taken preoperatively and postoperatively at 3 and 5 years of age. For the subjective evaluation a control group of 10 randomly selected children from a Child Welfare Centre were selected. For the objective evaluation the control group consisted of cephalograms from children born with cleft lip and palate who were matched regarding sex and age. Both cephalometric analysis and subjective studies of the outcome indicated improvement. When the forehead contour was investigated the number of patients who had been improved or corrected completely was higher when evaluated subjectively. When interorbital distance on cephalograms and intercanthal distance scores on VAS were evaluated, again the subjective study indicated improvement in more subjects.
