invades anterior orbital contents, skin of cheek, pterygoid plates, infratemporal
fossa, cribriform plate, sphenoid or frontal sinuses. Nasal cavity and ethmoid sinus:
Moderately advanced local disease. Tumor invades any of the following: anterior orbital
contents, skin of nose or cheek, minimal extension to anterior cranial fossa, pterygoid
plates, sphenoid or frontal sinuses. T1: Maxillary sinus: Tumor limited to the maxillary
sinus mucosa with no erosion or destruction of bone. Nasal cavity and ethmoid sinus:
Tumor restricted to any one subsite, with or without bony invasion. T2: Maxillary
sinus: Tumor causing bone erosion or destruction including extension into the hard
palate and/or middle nasal meatus, except extension to posterior wall of maxillary
sinus and pterygoid plates. Nasal cavity and ethmoid sinus: Tumor invading two subsites
in a single region or extending to involve an adjacent region within the nasoethmoidal
complex, with or without bony invasion. T3: Maxillary sinus: Tumor invading any of
the following: bone of the posterior wall of maxillary sinus, subcutaneous tissues,
floor or medial wall of orbit, pterygoid fossa, or ethmoid sinuses. Nasal cavity and
ethmoid sinus: Tumor invading the medial wall or floor of the orbit, maxillary sinus,
palate, or cribriform plate. N0: No regional lymph node metastasis. N1: Metastasis
in a single ipsilateral lymph node, 3 cm or less in greatest dimension. 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. M0: No distant metastasis. (AJCC 7th ed.);
