[Partial vertical surgery in the treatment of glottic carcinoma. Our experience in the course of 30 years].

Conversation surgery for glottic carcinoma has two goals: preserving normal laryngeal function and achieving a rate of local control similar to total laryngectomy. A retrospective study was made of the medical charts of 424 patients diagnosed as glottic carcinoma and treated with conservative surgical procedures at the Gregorio Marañón en University of Hospital of Madrid, Spain, between 1962 and 1991. Our treatment protocol for patients with early or intermediate-stage glottic carcinoma is presented.
