Marginal Mandibular Branch of Facial Nerve - A Literature review

Abstract

The Marginal Mandibular Nerve, a branch of the seventh cranial nerve (facial nerve), exhibits notable variability in its branching and course. Incorrect identification of the nerve and its branches poses a risk of injury during head and neck surgeries. The muscles supplied by the Marginal Mandibular Nerve are essential for maintaining facial symmetry. Preserving the functional integrity of the MMN is challenging during head and neck surgeries, and inadvertent injury to it can have significant consequences. Such an injury has the potential to distort facial expressions, underscoring the importance of careful consideration and preservation of the nerve during surgery. Therefore, meticulous attention to the anatomy of the Marginal Mandibular Nerve is crucial to minimize the potential for harm during surgical procedures in the head and neck region
