Analysis of treatment for isolated zygomaticomaxillary complex fractures
1Oral and Maxillofacial Surgery, University of Texas Southwestern Medical Center, Dallas, 75235-9109, USA.
Purpose:
The purpose of this study was to evaluate the adequacy of reduction and stability of fixation of isolated zygomaticomaxillary complex (ZMC) fractures treated by various methods over a 5-year period.
Patients And Methods:
Forty-eight patients with isolated, unilateral ZMC fractures that had at least 6 weeks' clinical follow-up were studied. Demographic information and methods of treatment were obtained from the medical records. Quality of reduction was assessed by examination of postoperative images. Stability of the repositioned ZMC was assessed by comparing immediate postoperative images with those obtained at least 5 weeks later. Cosmetic outcomes were assessed by clinical assessment and examination of photographs.
Results:
A variety of surgical approaches and fixation sites were used in the sample. All patients but five had satisfactory reductions performed during surgery. In two of the latter, no noticeable facial deformity was apparent. No patient showed postsurgical change in position of the reduced ZMC. Three patients showed postsurgical enophthalmos at longest follow-up. Approximately 20% of those having lower eyelid incisions had some amount of scleral show at longest follow-up.
Conclusions:
A variety of techniques can be used to produce a satisfactory outcome. Based on the results and a review of the literature, recommendations for treatment are proposed.
