Post-laryngectomy voice rehabilitation with a voice prosthesis in a young girl with advanced thyroid cancer.

The aim of this report is to evaluate the effects of voice rehabilitation with a voice prosthesis in a young patient with thyroid cancer. A 17-year-old girl underwent voice restoration with a voice prosthesis after laryngectomy to treat thyroid cancer. She completed voice-related questionnaires (the Voice Handicap Index-10 and Voice-Related Quality Of Life Survey) at ages 17 and 21 and underwent phonetic functional evaluation. The sound spectrograms of her phonation using the voice prosthesis showed low frequency sounds without an obvious basic frequency. She was ashamed of her hoarse voice and did not use her voice prosthesis during high school. However, after beginning to work at age 20, she used her voice to communicate in the workplace. At age 21, her questionnaire scores, especially those related to the physical and functional domains, improved compared with those at age 17. Voice restoration with a voice prosthesis is recommended for young patients who undergo laryngectomy for advanced thyroid cancer. The advantages of voice restoration with a voice prosthesis may increase when the patient reaches working age, and it may improve post-laryngectomy quality of life considerably.
