Zygomaticomaxillary complex fracture and chewable intraoral foreign body
Presentation
Incidental finding. Recent motor vehicle accident with left facial impact. The patient presents for a follow-up CT of the brain and facial bones following maxillofacial surgery.
Patient Data
Post operative assessment.
There is evidence of extensive left hemifacial and orbital smash injury with zygomaticomaxillary complex fractures, some partially treated with a plate and microscrews in a planned multistage orbital and facial bone repair. There is radio-opaque left maxillary antral hemostatic/ surgical filler material causing metallic artefact. There is a mesh in the floor of the left orbit. There is residual blood within the left nasal cavity. There is a resolving left frontal post-traumatic contusion. There are surgical staples within the scalp soft tissues with a superficial drain in situ.
There is an ovoid density within the right gingivo-buccal sulcus with intra-lesional and peri-lesional gas locules.
Case Discussion
An example of a radio-opaque comestible (chewable intraoral foreign body)1 within the right gingivo-buccal space. On questioning the patient, he confirmed the presence of a hard candy in his mouth at the time of the CT scan. Intraoral foreign bodies may mimic calculi/ bone/ soft tissue or a vascular mass and may lead to unnecessary further imaging investigations if not timeously realized.
The patient was involved in a high-velocity accident and suffered significant facial, orbital and frontal bone injuries.
