Most of the cases, as a result of fracture the arcus zygomaticus force the coronoid process and result in limited mouth opening and trismus. If these kinds of symptom will be seen the treatment is necessary. Conventionally, Keen, Gilles, Hook traction and open reduction treatment method and also new treatment modality can be use. For satisfied functional and aesthetically clinical results, meticulous approach is necessary. Our study’s aim is to present 9 isolated arcus zygoma fracture cases a point of clinical findings, treatment methods, and result. In addition, classification and treatment methods will be discussed in the light of literature reviews. In our study group we have 1 female and 8 male patient. Etiological factors are violence, falling, and sport accidents respectively 6 cases, 1 and 2 cases. Main compliment was limiting of the mouth opening in all patients. Keen’s method (Intraoral approach) and hook tractions method were preferred as a choice of treatment modalities. Only for one case, which is delayed arcus zygomaticus fracture, temporal approach was performed. After the operation along to 5-7 day, we performed intermaxiller fixation all the patients.
