# A Novel Long-Term Tympanostomy Tube: The U-Tube

## TL;DR

A new tympanostomy tube called the U-Tube was tested and showed a much lower risk of permanent ear perforation compared to traditional long-term tubes.

## Contribution

The U-Tube is a novel silicone-based tympanostomy tube designed to reduce permanent perforation risks.

## Key findings

- The U-Tube had a permanent perforation rate of 2.08%, significantly lower than conventional tubes (12–22%).
- Most tubes were removed electively, with minimal complications like otorrhea.
- Office-based removal was successful in all cases.

## Abstract

Purpose: Tympanostomy tubes are essential for middle ear ventilation, but conventional long-term tubes carry high perforation rates (12–22%). This study evaluated the Tympanostomy U-Tube (TUT), a novel silicone-based tube designed to minimize perforation risk by redistributing pressure away from the tympanic membrane rim. Methods: This was a retrospective cohort study of 192 ears in children aged 1–4 years who underwent TUT insertion for chronic otitis media with effusion or recurrent acute otitis media. The primary outcomes were tube insertion time and the permanent perforation rate. Mean follow-up was 38.4 months. Results: Mean tube insertion time was 21.6 months. Spontaneous extrusion occurred in 18.2% of ears (mean 24.5 months), while 81.8% underwent elective removal (mean 21.0 months). Permanent perforation developed in only 4 ears (2.08%; 95% CI: 0.6–5.2%), substantially lower than rates reported in the literature for conventional long-term tubes (12–22%), although the retrospective design and reliance on historical controls limit direct comparison. Complications were minimal, with otorrhea (36%) responding to topical therapy. Office-based removal was successful in all cases. Conclusions: The TUT provides intermediate-duration ventilation with a perforation rate comparable to that of short-term tubes, while avoiding the high perforation rates of conventional long-term tubes. Prospective randomized trials are needed to validate these findings.
