An objective assessment of treatment for orbital hypertelorism.
A retrospective statistical analysis of orbital hypertelorism correction was performed by comparing the preoperative and postoperative intercanthal distances of these patients with published age-matched normal values. Forty-five patients who had undergone surgery over a 15-year period with an average follow-up of 5 years (6 months to 14 years) were evaluated. Comparison of age-normalized preoperative and postoperative intercanthal distances revealed a significant difference for orbital hypertelorism patients as a group (p < 0.0001), patients with clefts (p < 0.0001), patients with nasoencephalocele (p < 0.01), and patients with frontonasal dysplasia (p < 0.05), but not for those patients with craniofacial dysostosis (p < 0.20). Multiple analyses of variance revealed a significant interaction existing between the extent of preoperative deformity and the cause of hypertelorism for both the postoperative deformity and the total amount of correction achieved, but not for the type of surgery or for the age at which the surgery was performed.
