Early glottic cancers (Tis, T1a, T1b, T2) involve one or both cords. They may have some supraglottic or sub glottic extension, and the cords maybe either freely mobile or at the most have impaired mobility. For in situ cancer, microlaryngoscopic excision either with cold steel or CO2 laser is the treatment of choice. In T1 glottic cancers, the treatment trends have swung towards laser excision away from both radiation therapy and open partial laryngectomy. In T2 glottic cancers, radiation therapy is the mainstay of treatment in majority of the cases.
