Abstract

Objective

The aim of this study was to investigate the treatment of zygomatic bone and zygomatic arch fractures without other facial fractures.

Patients and Methods

A 10 year (2000–2010) retrospective study involving 310 patients admitted and treated for zygomatic bone and zygomatic arch fractures at the department of oral and maxillofacial surgery was done. The data collection protocol included: age, gender, site, type of fracture. Other data presented included clinical diagnosis, radiographic examination findings as well as preoperative and postoperative imaging for evaluation of the fracture. Descriptive statistics was performed with SPSS version 16.

Results

The ages of the patients ranged from 10 to 76 years old, mean age was 32.33 years. 237(80.6%) of the patients were males and 73 (19.4%) were females (Table 1). According to the site of fracture, the patients were divided into three groups: group A, with zygomatic bone fracture, group B with zygomatic arch fracture and group C with co-existing zygomatic bone and zygomatic arch fracture. Regarding the site of fracture 57.7% of the patients had fractures of the zygomatic bone, 13.8% had fractures of the zygomatic arch and 28.4% had fractures of both zygomatic bone and zygomatic arch.

The treatment of both fractures was: closed reduction for isolated zygomatic arch fractures; open reduction and internal rigid fixation through a coronal incision was performed in comminuted arch fractures and displaced fractures.
