In 1978, Drs. Singer and Blom pioneered the methods of tracheoesophageal puncture and valved silicone voice prostheses that for over the past 35 years have become the international standard for voice restoration, allowing thousands of patients worldwide to regain their ability to speak. As a leading supplier of advanced voice restoration systems, our goal at InHealth is to help laryngectomees regain and preserve a vital part of their lives – their voice.

Blom-Singer® Voice Restoration System


By creating a small surgical puncture just inside the stoma, from the back wall of the trachea into the esophageal wall, a voice prosthesis can be placed into this passage to enable tracheoesophageal speech. Voice is produced by temporarily blocking the stoma so that exhaled air from the lungs can be directed from the trachea through the prosthesis into the esophagus and then out through the mouth. Fluent, conversational speech may be acquired within just a few days.
