Backgroud: esthetics could be as important as function in many patients suffering from zygomatic complex fractures. We
aimed to evaluate a modified intraoral approach for treating isolated monobloc zygomatic complex fractures with two-point
fixation at the zygomaticomaxillary buttress and infraorbital rim.
Method: This is a single armed (non-controlled) clinical trial carried on twelve patients who were assigned to our study
(n=12) with unilateral isolated zygomatic complex fracture. Treatment was evaluated clinically and radiographically using
three-dimensional computed tomography, infraorbital nerve function assessment was done through mechanical, thermal and
pain thresholds detection. Evaluation was done preoperatively, two-days, one week, one-month, two-months and three-months
Results: Study showed male predominance over females (12:0). The aged ranged from 1852- with a mean of 33. 11 out of the
twelve patients had the left side affected. Road traffic accidents was the major cause. Infraorbital nerve function was completely
restored within two-months postoperatively. Infraorbital nerve paresthesia completely disappeared within two-months in 11 of
our patients, one case reported persistent transient infraorbital nerve paresthesia.
Conclusion: the modified intraoral approach although technique sensitive, provides excellent esthetic and functional results.
Allowing the use of two-point fixation through a single incision avoiding any scars or postoperative complications to the eye
from using the extraoral approaches.
