This clinical report describes the clinical requirements, treatment sequence, and use of a relatively new intraoral electrolarynx for a completely edentulous patient. This device consists of a sound source attached to the maxilla and a hand-held controller unit that controls the pitch and volume of the intraoral sound source via transmitted radio waves.

Objective: Patients lose their voice after laryngectomy for laryngeal cancer or aspiration prevention surgery for severe dysphagia. To assist such patients, we developed and verified the utility of a novel vocalization method using a device termed the voice retriever (VR), in which the sound source is placed in the mouth.
Methods: We investigated the effectiveness of the VR in patients.

Electrolarynx devices have restored the voice of many who would otherwise be unable to speak. Current intraoral electrolarynx devices either have unappealing transoral tubes or are too large to easily fit in the mouth. We introduce a novel, remotely powered and wirelessly controlled intraoral electrolarynx that addresses these issues.

We developed and evaluated an intra-oral electrolaryngeal speech aid system for those who could not acquire common alaryngeal speech or for early post-surgery speech rehabilitation. Our system consisted of a denture-base intra-oral vibrator, a wireless miniature fingertip switch and a controller. To produce natural speech, the fingertip switch produced binary commands of voicing and accent and the controller implemented the pitch generation model using the commands.

Objectives: Tracheoesophageal fistula (TEF) construction, performed during or after total laryngectomy, is used for voice and speech restoration but has been associated with mild to severe complications. Our goal was to study the successes and complications in the application of this technique to restore voice function after laryngectomy in 95 consecutive patients.
Research Design: Retrospective cohort study with a mean follow-up time of 3.
