[Evaluation of late results of laryngeal cancer treatment with the use of polymer endoprostheses].

Application of biocompatible polymer-based endoprostheses (EG 1-4, TS 42-2-476-85) for the treatment of laryngeal cancer made it possible to achieve good oncological outcome in the late postoperative period and ensured high-quality functional rehabilitation of the patients. The estimated 3-year survival rate following endoprosthetic treatment amounted to 73.9%, 5-year survival rate was 67.6%, and 10-year survival rate 58.7%. Objective assessment of voice rehabilitation with the use of the <> software package (Windows 98, 2000, XP) demonstrated restoration of the vocal function in 70% of the patients while the remaining 30% were able to communicate by whisper speech. Resection of the larynx in patients with its stage II-III cancer in combination with the use of polymer endoprostheses yielded good oncological results and ensured the high rate of vocal function rehabilitation.
