Computed tomography scan evaluation of adequacy for reduction of zygomatic arch fracture using Gillie's temporal approach

Abstract

Aim: The zygomatic bone is the key component of the structural facial aesthetics as it constitutes the prominence of the cheek bone. Also, the most frequent clinical findings in zygomatic arch fracture includes limitation of jaw movement and flattening of cheek. So it is necessary to elevate the arch precisely. Therefore, a prospective study was conducted toevaluate adequacy for reduction of zygomatic arch fracture using Gillie’s temporal approach with the help of pre-operative and post-operative CT scan. Materials & methods: 4 patients, who received surgical treatment of zygomatico-maxillary complex (ZMC) fractures at the Department of Oral and Maxillofacial Surgery were examined for displacement of zygomatic arch pre-operatively with CT scan then re-evaluated the same site post-operatively. Results: The pre-operative mean displacement at the zygomatic arch, in millimetres (mm), was M = 2.8, SD = 3.011. After reduction, the post-operative displacement was M = 0.4, SD = 0.699. The percentage of reduction was M = 85, SD = 24.15. Conclusion: Gillie’s temporal approach for zygomatic arch fracture reduction is precisely considerable due to its simple and effective method and cosmetically more acceptable.
