Imaging of the sublingual and submandibular spaces

Abstract

Abstract Divided by the mylohyoid muscle, the sublingual and submandibular spaces represent a relatively small part of the oral cavity, but account for a disproportionate amount of pathological processes. These entities are traditionally separated into congenital, infectious/inflammatory, vascular and neoplastic aetiologies. This article reviews the relevant anatomy, clinical highlights and distinguishing imaging features necessary for accurate characterisation. Teaching Points • The mylohyoid sling is a key anatomical landmark useful in surgical planning. • Congenital lesions and infectious/inflammatory processes constitute the majority of pathology. • Depth of invasion is key when staging tumours in the oral cavity.
