Multidimensional Assessment of Voice Characteristics After Radiotherapy for Early Glottic Cancer

Abstract

Voices of patients diagnosed with early glottic cancer improved but did not normalize fully after radiotherapy. Stripping the vocal cord for initial diagnosis and continued smoking after treatment decreased voice characteristics. A multidimensional analysis protocol including perceptual and acoustical analysis of voice quality and stroboscopic analysis of vocal function is recommended to investigate voice characteristics following treatment for early glottic cancer.
