Abstract

Background: Divided zygoma (DZ) is an important structure in the midfacial
region. The anatomy of DZ is poorly researched, but knowledge about this entity
could be useful during posttraumatic facial reconstructions. The aim of this study
was to estimate the prevalence and anatomy of DZ in different regions around
the world. Therefore, the authors performed a meta-analysis, including all studies
that report extractable data on the DZ.
Materials and methods: The main online medical databases such as PubMed,
EBSCO, ScienceDirect, Web of Science, SciELO, BIOSIS, Current Content Connect,
Korean Journal Database and Russian Citation Index, were utilised to gather all
studies on anatomical characteristics, prevalence, symmetry, and a number of
divisions of zygomatic bone.
Results: A total of 20 studies were included in this meta-analysis. Data were
grouped and analysed in five categories: (1) prevalence of DZ bone, (2) prevalence
of DZ skulls, (3) gender prevalence of DZ with sides, (4) divisions of zygomatic
bone, (5) symmetry of DZ.
Conclusions: In conclusion, the authors of the present study believe that this
study can be considered an up-to-date meta-analysis regarding the prevalence,
divisions, and symmetricity of the DZ. The data provided by the present study
may be useful information for physicians in recognizing the DZ of the fracture
and may be important information during zygomatic bone osteotomy. Detailed
anatomical knowledge of the midfacial region can prevent surgical complications
when operating in this area.
