“…A transient or permanent sensory deficit around the skin of the chin, without affecting the sensation of the lower lip [235], has been reported following removal of the submandibular gland, during which the gland is physically separated from the NM [2233536], a bilateral sagittal split osteotomy (BSSO) [4], and post-genioplasty [35].…”

The NM contained sensory fibers per one histological study [6] and might provide sensory branches to the mandibular teeth [34789101112]. One study suggested that the NM supplies sensation to the premolar, canine, and incisor teeth with a frequency of approximately 60% [13].…”

The nerve to the mylohyoid (NM) originates from the mandibular division of the trigeminal nerve. The NM provides motor control to the mylohyoid and the anterior belly of the digastric. Its sensory component, as a variation of this nerve, has scantly been described in the literature. We discuss the current clinical implications of the NM based on its anatomical variations of the with the hopes of benefiting patients who are undergoing invasive maxillofacial procedures.

“…2 The MM and ADM, involved in mastication, deglutition, respiration and speech, are innervated by the MHN. 3,4 The nerve also carries the sensory information from other teeth. 5 Histological study 6 revealed that MHN contains fibres that might provide sensory innervation to the mesial root of the mandibular first molar, premolars, incisor teeth and the skin below the chin.…”

Background: The mylohyoid nerve is a branch of the inferior alveolar nerve (IAN), which is a branch of the posterior division of the mandibular nerve (MN). It is the source of motor nerve supply to the mylohyoid and anterior belly of the digastric muscle. At times, it provides sensory innervation to the mandibular teeth and skin below the chin. Since the location, anatomical variation and communications of the mylohyoid nerve are varied, it becomes clinically important to have an in-depth knowledge when treating patients for dental and maxillofacial procedures. Such anatomical variations of the mylohyoid nerve innervations may account for failure of the nerve blocks and hence, knowledge is very important for the practitioner. Materials and Methods: A thorough literature search was done using the key words mandibular nerve, communications of the mylohyoid nerve, inferior alveolar nerve, lingual nerve, failure of dental anaesthesia, mylohyoid nerve and dental implants "from the Databases-PubMed, Scopus Embase and Web of Science (years 1952-2020)". Results: The mylohyoid nerve may contain motor and sensory fibres, it may pass through the mylohyoid groove or canal and communicate with other nerves, which is clinically significant. Such anatomical variations may be one of the reasons for the failure of the inferior alveolar nerve block. Conclusion: Awareness of these variations is very significant in planning treatment and avoiding any unnecessary steps. The most frequently encountered anatomic variation of the mylohyoid nerve was innervation of the submental skin and the anterior teeth.
