EVALUATION OF THE Y-SHAPED MODIFICATION OF THE TRANSCONJUCTIVAL APPROACH IN OPEN REDUCTION OF ZYGOMATIC MAXILLARY COMPLEX FRACTURE (CLINICAL TRIAL)

Abstract

Introduction: Conventional incisions that are commonly used for the exposure of lower eyelid and treatment of Zygomaticomaxillary Complex (ZMC) fractures, includes both transcutaneous and transconjunctival approaches. The decision between the incisions is based on the need for adequate exposure of the fracture site and a desired aesthetically acceptable incision. A “Y” shaped technique was claimed to fulfill both adequate exposure and esthetic outcomes. Aim: This study was conducted to evaluate the Y-shaped modification of the transconjunctival in the management of zygomatic maxillary complex fracture. Materials and Methods: This study was based on seventeen patients with zygomaticomaxillary complex fractures. Post-operative patient evaluation was performed with consideration to intraoperative accessibility, exposure duration, postoperative pain and edema, post-operative wound healing and infection, scarring, and postoperative orbital movement and ocular complications. Results: The average exposure duration was (20:00±03:41) minutes, and the fractures were accessible in all of the operated cases. No scars were detected in all cases 6 weeks post-operatively. There was a significant difference between post-operative pain status in different intervals (p < 0.001). A significantly high percentage of cases didn’t have post-ocular complications 15(88.2%) (p < 0.001). Conclusion: The modification of the transconjunctival approach with a cutaneous Y-shaped incision provides commodious surgical exposure for ZMC fractures.
