Which muscles are typically targeted for sEMG monitoring of the Trigeminal nerve?

The masseter and temporalis muscles are typically targeted for surface electromyography (sEMG) monitoring of the Trigeminal nerve due to their direct innervation by the mandibular branch of this cranial nerve. The Trigeminal nerve, also known as the fifth cranial nerve, plays a crucial role in facial sensation and motor functions, particularly those involved in chewing.

Monitoring these specific muscles can provide valuable information about the function and integrity of the Trigeminal nerve during surgical procedures that may pose a risk of nerve injury. This is particularly important in surgeries involving the jaw or dental structures, where the functional status of the masseter and temporalis can indicate the health of the underlying nerve.

In contrast, although the other muscles listed may have neurological associations, they are not directly innervated by the Trigeminal nerve and thus do not provide the same level of relevance for monitoring in relation to thy nerve's function.
