When
zygoma fractures occur, the most typical symptoms are
paresthesias in the upper lip, nose, cheek, and lower eyelid,
diplopia, and pain. Particular physical characteristics that support zygomatic fracture include
globe injury, impaired ocular motility, globe malposition, orbital
emphysema,
trismus, palpable stepoffs at the inferior or upper lateral edge of the orbit, reduced feeling throughout the
infraorbital nerve's distribution,
subconjunctival hemorrhage, periorbital
ecchymoses, flattened
malar eminence, and widened facial appearance.[4]
Causes
High-impact trauma is almost always the cause of zygoma fractures. Assaults, car crashes, falls, and
sports injuries are the most frequent mechanisms.[5]
