Abstract

The mylohyoid nerve is also called nerve to mylohyoid (muscle). This nerve is a branch from the inferior alveolar nerve, which is very familiar to our dentists due to the frequently used block anesthesia for mandibular tooth treatment. The motor fiber is known to be the main component of the nerve that is distributed in the my-lohyoid muscle and anterior belly of digastric muscle. In this review article, the following contents will be discussed: the naming story based on the etymology, the general route and main function of the nerve, the research related to the failure of inferior alveolar nerve block anesthesia, and finally other miscellaneous anatomical research results and their clinical significance.

Key Words: Mylohyoid nerve; Mylohyoid muscle; Anesthesia; Inferior alveolar nerve
