Abstract
Background: Internal orbital reconstruction is a commonly performed procedure in management of zygomaticomaxillary complex (ZMC) fractures; however, it is not indicated in all cases. In management of orbital trauma, surgeons should not only correct the apparent defects, but also must reinstate the function of the orbit.
Purpose: This study aimed to assess the changes in the orbital volume following reconstruction with alloplastic materials in patients with orbital trauma.
Materials and Method: This retrospective study evaluated all patients with unilateral orbital fracture presenting to the Oral and Maxillofacial Surgery Department of Rajaie Hospital (from 2013 to 2016, Shiraz, Iran) who underwent corrective surgery. The computed tomography (CT) scans of patients were analyzed by Volumetry software to quantify the change in the orbital volume after surgical reconstruction of the orbital floor with alloplastic materials compared with the sound contralateral orbit. Data were analyzed using the Chi-square test and Student t-test (alpha=0.05).
Results: Significant differences were found in the volume of the traumatized orbit with sound contralateral orbit and the orbital volume after corrective surgery (p Value< 0.05). Corrective surgery was successful in all patients, and the orbital volume after treatment had no significant difference with the volume of the sound contralateral orbit (p> 0.05).
Conclusion: Corrective surgery with alloplastic materials can successfully regain the orbital volume in patients with orbital floor fracture, with no significant difference with the volume of the sound contralateral orbit.
