Small filters worn over the breathing hole in the neck after the voice box is removed. They warm, moisten and clean the air the nose used to, and covers and guards keep water and dust out when showering or outdoors.
After total laryngectomy air goes straight into the windpipe without passing through the nose. Heat and moisture exchangers (HMEs) clip into a baseplate stuck around the stoma or into a laryngectomy tube or button. Atos Medical's Provox Micron HME was cleared on 30 May 2008 (K072582, product code JOH). In England these are prescribed from Part IXA of the NHS Drug Tariff: in November 2026 it lists 482 rows of tracheostomy breathing aids, most from Severn Healthcare Technologies (207) and Atos Medical (137), including Provox Life HMEs and Provox LaryTube tubes, and 58 rows of tracheostomy and laryngectomy protectors such as Provox protectors and shower aids.
A foam or paper cassette in the stoma traps the heat and moisture of each exhaled breath and returns it on the next inhalation, adds a little breathing resistance like the nose did, and filters particles.
