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 2: The masticator space 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. Note 3: Use code 300 for localized tumor ONLY if no information is available to assign codes 105 or 205. Note 4: Use code 510, 585, 645, or 810 if the physician's assignment of T category is the ONLY information available about the extent of the tumor.

The complete definitions are provided in the General Rules, Section 2. Note 2: For nasopharynx, unilateral and bilateral retropharyngeal nodes are mapped to N1, and nodes in the supraclavicular fossa are mapped to N3b. The supraclavicular fossa is defined by 3 points: the superior margin of the sterna end of the clavicle, the superior margin of the lateral end of the clavical, and the point where the neck meets the shoulder. Note 3: For head and neck schemas, additional information about lymph nodes (size of involved nodes, extracapsular extension, levels involved, and location of involved nodes above or below the lower border of the cricoid cartilage) is coded in CS Site-Specific Factors 1,3-9. Note 4: If laterality of lymph nodes is not specified, assume nodes are unilateral. Midline nodes are considered unilateral. Note 5: For head and neck cancers, if lymph nodes are described only as "supraclavicular", try to determine if they are in Level IV (deep to the sternocleidomastoid muscle, in the lower jugular chain) or Level V (in the posterior triangle, inferior to the transverse cervical artery) and code appropriately. If the specific level cannot be determined, consider them as Level V nodes. Note 6: The description of lymph nodes has been standardized across the head and neck schemas. All lymph node levels and groups listed here are considered regional nodes for AJCC staging. Summary Stage 1977 and Summary Stage 2000 divide these nodes into regional and distant groups. Note 7: Most codes from CS Version 1 have been made obsolete and new codes added, to support AJCC assignment of N values for nasopharynx, which differs from the pattern for other head and neck sites. Retropharyngeal nodes have been moved from code 120 in CS Version 1 to code 050. Spinal accessory nodes have been moved from code 750 to code 110. Lower deep cervical and transverse cervical nodes have been moved from code 750 to code 120. Mandibular nodes are included with Facial nodes.
