Introduction. Zygomatic bone fractures are prevalent in the maxillofacial
region. This study aims at analyzing the epidemiology and clinical
presentation of isolated zygomatic bone fractures. Material and Methods. The
retrospective study, conducted at the Clinic of Maxillofacial Surgery of the
University Clinical Center of Vojvodina, included 128 patients diagnosed
with isolated zygomatic bone fractures. The following parameters were taken
into consideration: gender, age, trauma etiology, clinical presentation,
computed tomography analysis of the fracture localization and pattern. The
fractures were classified into five groups according to Zingg classification
system. Results. The study included patients aged 10-82 divided into four
groups, with the most affected group being 30-49 years old. Men were more
often treated for zygomatic bone fractures (male: female ratio 3:1).
Left-sided fractures of the zygomatic bone occurred more often (55.2%) than
the right-sided ones. Type B was the most common type of fracture, while the
zygomaticomaxillary buttress fracture was the most common injury. Early
treatment was administered in 78 patients (60.94%), while 50 patients
(39.06%) underwent delayed reconstruction. The analysis of complications
concerning the time of surgical intervention revealed a higher incidence of
ectropion in cases treated early, while infraorbital paresthesia and facial
asymmetry were more prevalent in cases treated late. Conclusion. Zygomatic
bone fractures have high morbidity risk, and may cause temporary incapacity
to work, and potentially permanent and functional damage.
