Aim:In this study, we aimed to evaluate the cosmetic and visual aspects of trigonocephaly in patients who did not undergo surgery during long-term follow-up.
Material and Methods:Six patients with trigonocephaly who did not undergo surgery were evaluated. In 3D CT images, frontal (the angle of the two lines between the bilateral pterion and nasion) and interfrontal angles were measured, and frontal projections at the first and last examinations were compared. The final appearances of the patients were photographed, and detailed eye examinations and OCT measurements were performed.
Results:Three boys and three girls were included in the study. The age at diagnosis of our patients was between 3 months and 2 years. The average age at diagnosis was 10.33 months. The average follow-up period of our patients was 34 months. The interfrontal angle was not below 118 degrees in any of our patients. As the follow-up period increased, the interfrontal angles also increased. The ophthalmologic examination differed according to the age of the patients. Extraocular motility testing revealed no abnormalities. The anterior segment and fundus examination results were within normal limits. Bilateral optical coherence tomography (OCT) images of the optic discs revealed a normal retinal nerve fiber layer (RNFL) thickness. No problems were detected in the neurocognitive development of the patients. No severe cosmetic pathology was observed.
Conclusion:Neurocognitive retardation and ophthalmological problems were not detected in unoperated trigonocephaly patients. More detailed studies with larger sample sizes are needed before changing our approach to the treatment of trigonocephaly.
