The orbits should be a routine check area on all CT Brain studies. In this case there was obvious orbit injury clinically.
Complications of zygomaticomaxillary complex fractures include trismus due to impingement of the temporalis muscle and damage to the infraorbital nerve resulting in paraesthesia in its sensory distribution.
