Mylohyoid Muscle Revisited: Anatomic Features with Clinical Implications in Dentistry

Abstract

The mylohyoid muscle, one of the suprahyoid group, forms the floor of the mouth. Its main function is swallowing. It is a margin between the sublingual and the submandibular spaces and is important in the pathway of oral and maxillofacial infection. In prosthodontics, it is one of anatomic landmarks that limits the lingual margin of the mandibular denture. Currently, the muscle receives much interest in the fields of maxillofacial reconstruction and rejuvenation. The hemorrhagic issue around the mandibular lingual region is usually involved with the mylohyoid especially in the dental implant installation. This review covers anatomic features of the mylohyoid muscle with diverse clinical implications.

The Digastric Muscle: Its Anatomy and Functions Revisited

“…The two bellies of the digastric muscle have different embryologic origins despite their common nomenclature; therefore, their innervation is different. The digastric muscle is one of four suprahyoid muscles and exists as a pair (Truong et al, 2022: Kim et al, 2023. The primary actions of this muscle are involved in chewing and deglutition.…”
