Trismus in the paediatric population


Trismus is a rare presentation affecting neonates, children, and adults. In newborns there are serious implications, with potential to affect feeding, cause airway problems, and make intubation difficult.

Causes of trismus seen in the paediatric patient are discussed in this review article; they are divided into intra- and extra-articular types.

The acquired group includes infective causes such as tetanus, iatrogenic causes related to drugs, cancer or dental treatment, and trauma causing articulation difficulty or triggering a rare type of bone growth in myositis ossificans.
