The Grace Medical 510‑121 Triune Vent Tube is a specialized tympanostomy (vent) tube designed to provide middle ear ventilation while minimizing postoperative complications such as tympanic membrane (TM) perforation. With an internal diameter of 1.35 mm and a short shaft length of 5 mm, this tube balances sufficient airflow with minimal intrusion. Its silicone construction (often referred to as PC silicone) ensures biocompatibility and flexibility, allowing the tube to adapt to the curvature of the TM and reduce risk of mechanical injury or abrasion.

A key innovation of the Triune design is its incorporation of three flanges arranged around the tube shaft. These flanges help stabilize the tube perpendicular to the tympanic membrane, preventing tilting or migration that could lead to edge erosion or perforation. Each flange is angled to closely contour to the natural shape of the TM, which further distributes contact pressure and lessens focal stress on adjacent tissue. According to manufacturer literature, these design considerations contribute to a lower long-term perforation rate (approximately 3 %) compared to conventional long-term T‑tubes (which may show perforation rates near 16.6 %).

Clinically, the Triune tube is intended for use in procedures requiring prolonged middle ear ventilation — for example, in chronic otitis media or recurrent effusion cases where standard short-term tubes may not suffice. Surgeons insert the tube through the myringotomy site using standard forceps; once in place, the three-flange geometry aids in maintaining correct alignment without continuous manipulation. Because the device is sterile and single-use, it helps streamline the surgical workflow and reduce cross-contamination concerns. Its MR-safe rating also allows safe use in patients subject to MRI studies in the future. In sum, the 510‑121 Triune vent tube offers a thoughtfully engineered balance of mechanical stability, ventilation efficacy, and tissue safety in otologic procedures.
