UNILATERAL ZYGOMATIC COMPLEX FRACTURE – A COMPARISON BETWEEN NON-
SURGICAL TREATMENT AND SURGICAL TREATMENT

Ling XF, Yew CC, Mohd Nazri S, Tew MM
Introduction: Medical advances have enabled zygomatic complex (ZMC) fractures to be
treated by various approaches. Objective: To analyse the demographics and treatment
outcomes of unilateral ZMC fractures, treated non-surgically or surgically. Materials and
methods: This 5 year non-randomized prospective study included 65 cases of unilateral
ZMC fractures from October 2014 until December 2019. Patients were treated and
divided into non-surgical and surgically treated group. Treatment outcomes in terms of
step deformities, malar depression, diplopia, infraorbital hypoaesthesia and mouth
opening were evaluated up to 6 months post trauma/intervention. Results: Road traffic
accident (96.9%) was the main cause, with predominant male involvement (80%) and
median age of 28 years. Significant improvements (p<0.05) were observed for step
deformities and malar depression among the surgically treated group at post-operative
day 1 and week 1. Throughout the 6 months review, infraorbital hypoesthesia and
diplopia showed no significant differences between both groups, (p>0.05). Besides, all
patients showed significant mouth opening improvement (p < 0.05) over 6 months period.
Conclusion: We found that infraorbital hypoaesthesia and limited of mouth opening
should not be the absolute indications for surgical treatment of ZMC fractures. Non-
surgical treatment that included early jaw exercise and symptomatic treatment had
potential value for satisfactory functional gain.
