For a mobile tumour on vocal cord, treatment is

GLOTTIC CARCINOMA T2N0:- It implies tumour of the glottic region, i.e. vocal cord(s), anterior commissure and/or vocal process of the arytenoid with extension to supraglottic or subglottic regions but with no lymph node involvement. Treatment depends on two factors:- 1. Is mobility of vocal cord normal or impaired? 2. Is there involvement of anterior commissure and/or arytenoid? If cord is mobile and anterior commissure and arytenoid are not involved, radiotherapy gives good results. Such patients are kept under regular follow-up. If disease recurs, total laryngectomy is performed. If anterior commissure and/or arytenoid are involved or cord mobility is impaired, radiotherapy is not preferred because of the possibility of developing perichondritis which would entail total laryngectomy. In such cases, some form of conservation surgery such as veical hemilaryngectomy or frontolateral laryngectomy is done to preserve the voice. Such patients are also kept under regular followup and conveed to total laryngectomy if disease recurs. Ref:- Dhingra; pg num:-311
