The Gyrus ACMI 70140280 Paparella-type vent tube is an implantable transtympanic ventilation tube used to maintain aeration of the middle ear, typically inserted via the tympanic membrane (myringotomy). The 1.14 mm internal lumen allows sufficient airflow while remaining small enough to minimize disruption to the tympanic membrane. The tube is constructed from biocompatible silicone, chosen for its inert properties, flexibility, and low tissue reactivity. Its blue coloration aids in visualization during placement or inspection.

This particular version includes an insertion tab and a notched inner flange designed for a “twist-in” insertion technique, which helps stabilize the tube once placed in the tympanic membrane. The flange design enhances retention, reducing the likelihood of spontaneous extrusion or displacement over time. The manufacturer and vendors describe it as “very stable for long-term implantation,” implying that the tube is intended to remain in place until it is extruded or removed clinically.

Clinically, Paparella-style tubes like this are used to treat chronic otitis media with effusion, recurrent middle ear infections, or eustachian tube dysfunction by permitting ventilation and drainage of the middle ear space. The 1.14 mm lumen balances airflow efficacy against risk of clogging or debris accumulation. The silicone body helps resist biofilm formation and tissue inflammation, while its design (flanges, tab) seeks to strike a balance between retention and safe removal when necessary. Because detailed mechanical or material data (e.g. wall thickness, flexural stiffness, stress tolerances) is not publicly disclosed, surgeons rely on the IFU (Instructions for Use) and manufacturer guidelines during selection, placement, and long-term monitoring.
