PURPOSE: To evaluate possible associations between the degree of reduction, remaining dislocation (mm), fracture type, and the sequelae from which the patient may suffer postoperatively in patients with zygomaticomaxillary fracture managed by closed reduction.
MATERIAL AND METHODS: A 3-year retrospective audit was undertaken to identify all patients who had sustained a fractured zygoma and were operated on by closed reduction at the Ear, Nose, and Throat Department, Karolinska University Hospital, Huddinge, Sweden. Patients were followed up by mail questionnaire and postoperative computed tomography (CT).
RESULTS: The odds of having symptoms (odds ratio [OR] 4.26, confidence interval [CI] 1.09-18.44) was significantly higher in the group with a reduction less than 100% (n = 34) compared with the group with 100% reduction (n = 17) (P = .035). The odds of having symptoms (OR 9.91, CI 0.89->500) was higher in the group with remaining dislocation 6 to 10 mm compared with the group with no remaining dislocation (P = .069). The type of fracture (A, B, or C) also influenced the patients' postoperative symptoms. The odds of having symptoms was 48.40 (CI 4.60->500) times higher having fracture C compared with fracture A (P < .001).
CONCLUSIONS: The degree of reduction and remaining dislocation of zygomaticomaxillary fractures is important to achieve a good postoperative result, that is, reducing the patient's postoperative symptoms. Furthermore, the type of fracture also influences the patient's long-term sequelae.
