ISOLATED ZYGOMATIC BONE FRACTURE

Facial bones injuries results in functional disturbances. Patientsmay presents with flattening of normal malar prominence, lid drop, eye movement limited orwith double vision, numbness of cheek area and unilateral epitasis. Emphasizing upon incisiontype, fixation method and occasionally reconstruction, surgeons suggest different methods forrepairing complex fractures of Zygoma. Study Design: Descriptive study. Setting: Departmentof Oral & Maxillofacial Surgery, Liaquat University of Medical & Health Sciences, Jamshoro.Period: Mar 2013 to Feb 2014. Materials and methods: Total 20 patients were included.Patients with fracture more than 28 days old were excluded. Zygomatic bone can be approachedby lateral brow or subcilicary incisions and by subgingival buccal sulcus approach. When 3fracture sites were reduced and aligned satisfactorily, application of miniplates was performedat 3 points frontozygomatic suture, Zygomatico maxillary buttress and infraorbital rim, woundwere closed in 2 layers. At 2nd week follow-up patients were assessed for outcome. Results:There were 14 male and 6 female patients. Most were of age <25 years. 45% fractures weredue to RTA. Duration of fracture of 2 patients was 2 days, 7 days of 11 patients, 4 patients had14 days and 3 patients had 28 days. 5 fractures were reduced using Gilies temporal approach,6 with Keen approach, 4 with Hook approach and 5 with Dingman approach. Preoperatively,17 patients had facial asymmetry, 19 had limited mouth opening and postoperatively this wasreduced to 6 cases each for facial asymmetry and limited mouth opening. Conclusion: Itis concluded from this study that three point fixation is most effective and safe method forreduction of fracture of Zygomatic bone.
