]> C10.1 Anterior surface of epiglottis Note: AJCC includes lingual (anterior) surface of epiglottis (C10.1) with larynx. SEER Extent of Disease included it with oropharynx. &generalsize; CS Extension Note 1: Impaired vocal cord mobility, also described as vocal cord paresis, may suggest invasion of intrinsic laryngeal muscle. Fixation of the vocal cord may be described as immobility of the arytenoids noted on endoscopy, vocal cord cord paralysis, or deviation of larynx to fixed side. Note 2: Use code 300 for localized tumor only if no information is available to assign codes 100, 200, or 310. Note 3: Use code 355, 435, 725, 810, or 815 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 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 3: If laterality of lymph nodes is not specified, assume nodes are ipsilateral. Midline nodes are considered ipsilateral. Note 4: 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 5: Level IV nodes have been moved from code 100 in CS Version 1 to code 120. Mandibular nodes are included with Facial nodes.
