Voice rehabilitation with Provox2™ voice prosthesis following total laryngectomy for laryngeal and hypopharyngeal carcinoma

Provox2 voice prosthesis speech was very useful due to the higher rate of speech restoration, longer phonatory time, and better intelligibility. It was also thought that voice prosthesis speech was useful in conjunction with esophageal speech and an artificial larynx depending on the patient's condition or wishes.
