The suture previously placed through the lateral pterygoid muscle was looped around the neck of the mandibular component to secure the muscle to the prosthesis.
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 muscle markings end at a bondy lip, which served as an anchor for the medial pterygoid, the Israeli researcher notes.
The dentary, palatine, and pterygoid teeth from 11 skulls vary from 21 to 24, 22.
Less common sites include the sphenoid sinus, around the sella or at the inferolateral or pterygoid recesses.
Infection may also spread to the medial pterygoid or masseter muscles.
Other gross lesions included verminous pterygoid sinusitis and pneumonia and mild dermal and retroperitoneal cestodiasis.
5 mm bony lesion of the mandibular angle, eroding the cortex and infiltrating the associated medial pterygoid muscle, was revealed (Fig 2b).

VAN WADLINGTON, MD: Computed tomography (CT) examination revealed thickened tissue around the right external auditory canal, opacification of the mastoid air cells, and swelling of the right pterygoid muscles and retropharynx (Figure 1) as well as occlusion of the right sigmoid sinus and jugular bulb.
