Análise videolaringoestroboscópica de pacientes submetidos à radioterapia para tratamento de câncer glótico

Abstract

Summary Radiation therapy is an adequate treatment for early laryngeal cancer, and it is important to study the vocal fold vibratory pattern, which is essential for a favorable voice outcome. Aim To analyze laryngostroboscopic findings in a group of patients who underwent radiation therapy for the treatment of early glottic cancer. Methods A retrospective study was conducted in order to evaluate 20 patients staged as T1a glottic tumors in the period from 1995 to 2005. A laryngostroboscopic protocol was applied. Results Glottic closure was complete in 17 patients. The amplitude was normal in 14 treated vocal folds and in 18 contralateral vocal folds. The mucosa wave vibratory pattern was totally present in all vocal folds. The periodicity was always regular in all cases. The vestibular fold and arytenoid symmetry and movements were normal. There was occasional supraglottic lateral constriction in 4 cases. The mucosal appearance was normal in 14 and edematous in 6 patients. Mucus build up was observed in 12 patients. Conclusions The vibratory pattern was normal or slightly diminished in both vocal folds after radiation therapy for early glottic cancer.
