A prospective randomized study of four commonly used tympanostomy tubes.

Tympanostomy tube placement has clearly been shown to be an efficacious treatment for recurrent bouts of acute otitis media or chronic otitis media with effusion. However, there are few objective, prospective, randomized studies present in the literature to aid the clinical otolaryngologist with the proper tube choice for middle ear aeration. A prospective, randomized study was undertaken of four commonly used tympanostomy tubes. Shepard Teflon grommet, Armstrong beveled tube, Reuter-Bobbin tube, and Goode T-tube. This study was undertaken to determine which of these tubes had the fewest number of postplacement complications, including otorrhea, plugging, residual perforation, or chronic persistence in the tympanic membrane. Average follow-up was 17 months. The Shepard and Armstrong tubes showed a comparatively low rate of plugging and otorrhea. Both tubes had extrusion times that averaged less than 1 year. The Reuter-Bobbin tube had a much greater rate of plugging, compared to the other tubes. The T-tube had an increased incidence of otorrhea and persistence in the tympanic membrane well beyond 1 year. The T-tube was also the only tube in this study associated with residual perforations.
