Changing the indwelling Provox tracheoesophageal voice prosthesis as an out-patient procedure.
The use of the indwelling tracheo-oesophageal prosthesis is gaining popularity for vocal rehabilitation after laryngectomy. These devices can often provide trouble-free phonation for many months before they become incompetent or require increased effort to open them. When this occurs changing the defective valve for a new one is required. We describe simplification of the technique described by the manufactures which is eminently suitable for use as an out-patient procedure under local anaesthesia.
