Oesophageal valves are made of medical grade silicon rubber and primarily consists of four parts: One-way valve, two flanges on each side of the tube, rigid valve ring in the middle of the tube, and a safety strap that is either removed after the insertion, or left on the device depending on whether it is in-dwelling or patient-changeable.

Speech prostheses, or voice prostheses, is a overall term for small, silicon one-way valves that are inserted into the tracheo-oesophageal puncture of laryngectomy patients. The prosthesis not only safely divides the oesophagus and trachea, but also allow speech when the outside of the tracheostoma, the opening on the neck to allow air in, is covered with a finger or otherwise occluded. This is greatly beneficial to patients because it allows to communicate without the need to use either an Electrolarynx or Speech synthesizers.

Main characteristics
Oesophageal valves are made of medical grade silicon rubber and primarily consists of four parts: One-way valve, two flanges on each side of the tube, rigid valve ring in the middle of the tube, and a safety strap that is either removed after the insertion, or left on the device depending on whether it is in-dwelling or patient-changeable. The two flanges are tracheal flange and esophageal flange respectively. They vary in rigidity and size. Both depend on the valve being patient-changeable or not, with the latter being bigger in size and rigid so as to facilitate bigger longevity. The overall size, especially the diameter of the tube depends on patient's preference and the size of the tracheo-oesophageal puncture.
Usage of a valve for voice restoration was first described by a Polish laryngologist Erwin s. Mozolewski in the 1970s.[1] First commercially available oesophageal valve was introduced in the late 1970s, which was introduced by Eric Blom and Mark Singer and was considered a major step in voice restoration. Up to the introduction of this procedure, laryngectomy patients were required to learn oesophageal speech or use an electrolarynx to be able to communicate again.[2] In 1985, inserting oesophageal valves has been accepted as a primary procedure in the US.[3]
Purpose
The purpose of speech prostheses is to return the ability to speak to patients after total laryngectomy.
