Summary
Multiple facial injuries caused significant trismus in a patient due to retained foreign-body fragments. This case highlights an unusual cause of limited mouth opening, distinct from typical coronoid process or fibrous adhesions.
Area of Science:
- Oral and Maxillofacial Surgery
- Trauma Surgery
Background:
- Trismus, or limited mouth opening, is often caused by factors affecting the temporomandibular joint or masticatory muscles.
- Common extracapsular causes include coronoid process impingement and fibrous adhesions.
- Foreign-body retention following facial trauma is an infrequently reported etiology of trismus.
