An interesting clinical finding was also the deviation of the mandible towards the healthy side, a fact that could be attributed to the implication of the mylohyoid
muscle which takes part in the opening motion.
Bilateral submandibular gland aplasia with clinico-radiological mass due to prolapsing sublingual salivary tissue through mylohyoid
boutonniere: a case report and review.
They can arise above or below the mylohyoid
muscle, and they may become symptomatic as a response to infection or trauma.
Ranulas are classified as either "simple" and confined to the sublingual space, or as "plunging" with extension through the floor of mouth and below the mylohyoid
The muscles of mouth closure--the masticatory muscles: temporalis, masseter, and medial pterygoid--exert a power 10 times greater than the power of the mouth-opening muscles (lateral pterygoid, digastric, mylohyoid
, and geniohyoid muscles).
Although skeletal muscle commonly harbors the cysticerci, we report a case in which they had infested the mylohyoid
muscle in the floor of mouth, a site that has not been mentioned previously in the literature.
The swelling did not extend beyond the submandibular triangle, and the clinical opinion was that it was localized on the floor of the mouth, above the mylohyoid
The lesion was below the intrinsic tongue musculature but within the mucosa overlying the extrinsic tongue musculature, abutting and possibly involving the anterior portions of the genioglossus and mylohyoid
muscles (figure 1).
In the head and neck, several different muscles may be affected: the sternocleidomastoid, mylohyoid
, digastric, temporalis, tongue, and perioral group muscles.
Computed tomography (CT) showed a well-circumscribed heterogenous lesion cephalad to the mylohyoid
muscle (figure 1).
Oral ranulas are localized superior to the mylohyoid
muscle, whereas cervical (plunging) ranulas extend into the neck along fascial planes.
The large superficial aspect and small deep portion of the submandibular gland are continuous around the free posterior border of the mylohyoid
