Isolated Zygomatic bone fracture: assessment of outcome by two point fixation.

Abstract

Objectives: The purpose of the present study was to assess the outcome of two-point fixation in isolated zygomatic bone fracture. Study Design: Descriptive study. Setting: Department of Oral & Maxillofacial Surgery, Faculty of Dentistry, LUMHS, Jamshoro/Hyderabad. Period: From 1/3/2018 to 31/8/2018. Material & Methods: Consisted of 46 patients with displaced isolated zygomatic bone fractures. All fractures were treated by reduction with transoral (Keen’s) approach & fixation was done by two point fixation with titanium miniplates. Patient was discharged from the hospital next day & advised follow-up after two weeks. Mean ± St & ard deviation was computed for qualitative variables. Diplopia was described in frequencies. Mouth opening was measured on 7^th day or 1 month & measured in 1mm by metallic ruler. T-test was applied to find the P Value. Results: There were 34 male & 12 female patients. 56.5% injuries were caused by road traffic accident. Mean mouth opening at 1^st week was 25.23±5.15mm & at 2^nd week was 38.75±2.00 mm. At 1^st week diplopia was found in 26.1% subjects while at 2^nd week, diplopia was found in 10.9% subjects. There was significant difference in mean mouth opening at 1^st week with 2^nd week. The results also showed significant association of diplopia at 1^st week with 2^nd week. Conclusion: isolated zygomatic fractures can be reduced & immobilized by two-point fixation with screws & titanium mini bone plates at frontozygomatic & the zygomatic buttress area. Post-operative complications i.e. opening of mouth & diplopia were suggestively decreased afterward 15 days of treatment.
