Notes
**Note 1:** The intrinsic muscles of tongue are four paired muscles within the tongue which control its shape. The extrinsic muscles originate from structures outside the tongue and control its positioning. **Note 2:** Parapharyngeal involvement (pharyngeal space invasion) (code 700) denotes postero-lateral infiltration of tumor beyond the pharyngobasilar fascia. The pharyngobasilar fascia is the fibrous layer of the pharyngeal wall between the mucosa and the muscular layer, attached superiorly to the basilar part of the occipital bone and diminishing in thickness as it descends. **Note 3:** The masticator space (code 700) primarily consists of the muscles of mastication, the medial and lateral pterygoid, masseter, and temporalis muscles. The space also includes the ramus of the mandible and the third division of cranial nerve V as it passes through the foramen ovale into the suprahyoid neck.Default
