Clinical analysis of 12 patients with zygoma fracture observed during recent 16 months was presented. Of them, 10 cases were in the age of 20-23 years and other 2 were 26 and 47 years respectively. Five cases were hit by a stone. Other causes were traffic accident, fall down and sports. Main symptoms and signs were paresthesia of cheek, upper teeth numbness, cheek and periorbital swelling, ecchymosis, pain and tenderness, facial deformity. The associated injuries were tooth fracture, loss of consciousness, nasal bone fracture, optic nerve injury and fractures of other parts of body, and they were frequently found in case of traffic accident and fall-down. All the cases were checked with plain films and computed tomogram. Rotation or displacement of fractured body was common. Lateral vertical rotation and lateral horizontal rotation were in 3 cases respectively, and medial vertical rotation was in 1 case. Inferior displacement was in 2 cases, postero-inferior displacement was in 2 cases, postero-lateral displacement was in 1 case and medial displacement was 1 case. Orbit lateral rim and infraorbital rim fracture were in 11 cases respectively. Maxillary sinus lateral wall fracture was in 9 cases. In 7 of 12 cases, direct or indirect reduction was done, without fixation in 2 cases and with interosseous wiring of fronto-zygomatic suture in other 5 cases, through the lateral eyebrow incision and/or infraorbital incision. In one case, malar augmentation was performed with silastic material 3 months later. In 4 cases neither reduction nor reconstruction was done because of minimal deformity, delayed state, or optic nerve injury. It is considered that early diagnosis and adequate treatment should be performed in any cases of traumatic zygoma fractures for not remaining any complications.
