Cephalometric evaluation of ocular protrusion at stages of growth.
The sagittal relationships between the orbital globe and the ocular orbit have great importance in aesthetic and functional evaluations. These relationships are useful in diagnosis and treatment of some malformations in which the orbital volume is reduced such as craniostenosis. The aim of the present study was the cephalometric evaluation of the ocular protrusion at different growth stages. Ninety-two patients with negative history of craniosynostosis, severe myopia, and skeletal class I were selected for the present study. Lateral teleradiography x-ray was performed for all the patients, and 5 groups were carried out based on the dentition phase. Cephalometric analyses were performed on the lateral teleradiography x-ray. Mean values of ocular protrusion (B-Or post) for females and males were found and digitized for the 5 groups tested. All other sagittal and vertical measurements were successfully computed by the trained operator. B-Or post showed values between -14.93 mm and -16.90 mm among the groups. The cephalometric analysis proposed in the present study allowed to successfully evaluate sagittal and vertical relationship of the orbital globe and the orbital cavity in growing patients. Moreover, the B-Or post maintained its value during growth in the present study.
