Comparative Study of Osseous Alignment in Isolated Tripod Zygomatic Bone Fracture Osteosynthesis At Frontozygomatic Suture Versus Zygomaticomaxillary Suture
Background: Zygomatic fractures constitute the second leading facial skeleton fractures, after fractures in the nasal bone. The treatment for zygomatic fractures has been more advanced with various treatment methods. Fixation has been used sporadically by few surgeons ZMC region at frontozygomatic suture and zygomatic buttress. Objective: To compare the osseous alignment in isolated tripod zygomatic bone fracture with one-point osteosynthesis at frontozygomatic suture versus zygomaticomaxillary suture. Study Design: Comparative study. Settings: Department of Oral and Dental Surgery, Shaikh Zayed Medical College Hospital Rahim Yar Khan-Pakistan. Duration: From July 2016 to June 2017. Methodology: Patients with isolated tripod zygoma fracture were included in this study. The patients were allocated two different group’s i.e; group (A), with osteosynthesis at the site of zygomaticofrontal suture and group (B), at zygomaticomaxillary suture site. Each group carried 25 patients equally. Pre-operatively, the diagnosis of displaced zygoma fractures was established following clinical and radiographical examination via 3-D C.T scan imaging technique. The osseous alignments were noted in the first follow up visit and more visits upto 3 weeks. Results: The predominant age group in the study was mainly found to be in third decade of life (52%). Male gender represented the majority (72%) in the study. The post-operative osseous alignment in group (B) patients, (92%) were observed more stable and better than group (A), (76%) in all follow up visits. Conclusion: Single Point fixation of isolated tripod zygoma fracture at either site; zygomaticofrontal suture or zygomaticomaxillary suture may give satisfactory results with a mild difference in post-operative osseous alignment if reduced properly, but slightly better in zygomaticomaxillary site. Good results can be achieved of zygoma fracture both cosmetically and functionally if it is treated within a week.
