The Grace Medical Triune Vent Tube (510-121) is a patented, long-term silicone tympanostomy tube designed for middle ear ventilation. It features a unique three-flange design that maintains perpendicular alignment with the tympanic membrane (TM), reducing trauma and minimizing the risk of tube migration and TM erosion. The Triune tube is 1.35 mm in lumen diameter and 5 mm in length, and is supplied sterile, packaged 5 tubes per box.
Key Features
- Three angled flanges hold the tube securely and perpendicular to the TM, minimizing unnecessary erosion and trauma.
- Soft, contoured silicone construction for patient comfort and reduced tissue reactivity.
- Low perforation rate: Clinical studies show a 3.0% TM perforation rate versus 16.6% for standard long-term T-tubes.
- Longer ventilation duration than grommet tubes, with fewer complications than traditional T-tubes.
- Easy insertion with standard forceps.
- Sterile, single-use; packaged 5 per box.
- Dimensions: 1.35 mm lumen diameter x 5 mm length.
