EOD Primary Tumor
This input is used for staging
Notes
**Note 1:** Impaired vocal cord mobility may be described as vocal cord paresis, and may suggest invasion of intrinsic laryngeal muscle. Fixation of the vocal cord maybe described as immobility of the arytenoids noted on endoscopy, paralysis of the vocal cords, or deviation of larynx to the fixed side. **Note 2:** Code 100 for localized tumor only if no information is available to identify further extension.Default
