Otological Ventilation Tubes are available in the following designs:
Otological Ventilation tubes are designed for easy placement through the tympanic membrane to ventilate the middle ear space, and, if present, drain accumulations of fluid from the middle ear.
These tubes act as ventilation devices allowing a free exchange of air between the outer ear and middle ear space, equalizing the air pressure on both sides. When fluid is present, the ventilation tubes can also act as drain devices allowing fluid to drain from the middle ear space to the external auditory canal.
These tubes are available in a variety of designs, sizes and materials to best suit the doctor's preference and need.
The materials used to manufacture Tecfen Ventilation Tubes are Silicone, Fluoroplastic, and Polyethylene. These materials have long histories of use as implanted medical devices. They are known for their smoothness of texture, inertness, biocompatibility, and effectiveness for both short- and long-term middle ear drainage and ventilation.
The color of Tecfen Silicone and Polyethylene Tubes are blue, and Tecfen Fluoroplastic Tubes are white.
Sterilization of these tubes is by ethylene oxide gas under a tested, controlled cycle. Each lot is tested for sterility in accordance with United States Pharmacopeia guidelines.
All Fluoroplastic and Silicone Tubes may be sterilized or resterilized by any commonly accepted method. Polyethylene tubes should be sterilized or resterilized by gas or cold sterilization solutions only.
