maxillary sinus, skin of face). T4b: Tumor invades masticator space, pterygoid plates,
or skull base and/or encases internal carotid artery. N2: Metastasis in a single ipsilateral
lymph node, more than 3 cm but not more than 6 cm in greatest dimension; or in multiple
ipsilateral lymph nodes, none more than 6 cm in greatest dimension; or in bilateral
or contralateral lymph nodes, none more than 6 cm in greatest dimension. N2a: Metastasis
