Medially, it abutted and displaced the adjacent anterior belly of the digastric and mylohyoid muscles.
To avoid significant postinjection dysphagia, anterior digastric muscle injections were performed superficially to avoid diffusion into the floor of the mouth and tongue base musculature.
As such, the trochanteric osteotomy is not digastric, as first described by Mercati and colleagues (22) but is trigastric.
Braking is done with muscle movement: posterior digastric, digastric and sternohyoid previously.
This more limited genial advancement procedure does not reposition the digastric muscle or the hyoid bone, and delayed muscle detachment associated with these procedures has been reported.
We recorded EMG activity (or submental EMG [SMEMG]) on the second channel of the EMG apparatus using bipolar silver chloride EEG (electroencephalographic) electrodes taped under the chin over the mylohyoid-geniohyoid-anterior digastric muscle complex (Figure 1(a)-(b)).
The level of digastric muscle activity was important and reflected the severity of the condition.
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).

The tumor was bound anteriorly by the anterior digastric muscle and posteriorly by the sternocleidomastoid muscle and retromandibular fossa.
Based on the results of a biologic study of circulation patterns at the proximal femur, Nork and coworkers recommended that SRA be performed through a posterior or lateral approach, combined with digastric osteotomy of the greater trochanter to minimize the chance of disrupting the MCFA (located distal to piriformis insertion) and its terminal contribution to femoral head circulation.
