Reduction of Zygomatic Bone Fracture by Two Different Treatment Protocols.
Pak J Med Dentistry Jan ;10(3):42-6.

Background: Zygomatic bone, a malar bone or cheekbone usually works as eye socket. All over the world, around 15 to 20 million people are traumatized with road accidents. Over 50% of these statistics are diagnosed with zygomatic fractured bone. There are different approaches of therapy to treat zygomatic fractured bone. In this research, two approaches have been studied. The Percutaneous Hook approach is extraoral while Keen’s approach is intraoral. The objective of this study was to evaluate outcomes of two different treatment protocols (percutaneous bone hook method and Keen’s method) for reduction of zygomatic bone fracture. Methods: This comparative analytical study conducted at the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Liaquat University Hospital, Hyderabad, Pakistan. Subjects with displaced isolated zygomatic bone fracture were divided in two groups, Group A (Percutaneous Hook Method) and Group B (Keen’s Method). The data was analyzed through SPSS and p<0.05 was considered as statistically significant. Results: Males were predominantly affected in both groups as compared to females i.e., Group A male patients were 22(73.52%) while in Group B male patients were 23(79.41%). Road traffic accidents were the most common etiological factor in both groups. There was a significant difference between the groups in diplopia, cheek flattening and mean mouth opening at postoperative 2nd, 4th and 6th week. The obtained p-value=0.01 was less than 0.05; therefore, the results were statistically significant. Conclusion: It was observed that percutaneous hook method had better outcomes compared to Keen’s method in reducing isolated zygomatic bone fracture.
