About this study
Pilot study done to evaluate the breakdown and and potential utility of a bioabsorbable ventilation ear tube made with gelatin.
Read the detailed description
Institutional Review Board- Park Nicollet Institute approval was granted 3/2011 for 15 patients to be enrolled in pilot study of use of a bioabsorbable ventilation ear (PE) tube. IRB stated compliance with FDA as defined in 21 CFR, Part 56 and with regulations of DHHS. Federal assurance number FWA00000914. Prior to commencing this study, IRB approval was obtained and each participating clinician completed the NIH training for "Protecting Human Research Participants".
14 patients (15 ears) were enrolled in this study and were examined by 2 independent examiners at approximately 3, 6 and 12 week follow-ups. Lumen patency and time to complete resorption were documented by each examiner. There were no adverse reactions. This pilot study suggests that there is utility for a bioabsorbable ear tube made from gelatin material, as the device was found to break down over the expected time frame and remained functional long enough to have clinical utility.
- Being tested
- PE tube
- Medical subject headings
- Hearing Loss, Sudden, Meniere Disease
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
PE tubeDevice
Gelatin mixed with antibiotic and steroid ear drop to create a rigid device that maintains a lumen, acting as an intermediate-duration bioabsorbable ear tube.
| Study group | Role | What they receive |
|---|---|---|
| Meeting indication for short term ventilation tube placement | Experimental | Adult patients meeting standard criteria for short-term ventilation tube placement were offered placement of a bioabsorbable ear tube in place of a durable ear tube that would later be removed. Receives: Device: PE tube |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of weeks that ventilation tube lumen is patent.
Primary outcome was presence of a lumen, reflecting a functional device.
Measured: 0-3 months
Secondary outcomes (1)
Number of weeks until ventilation tube is fully resorbed.
Gelatin has been used in this site as packing material and has been shown to resorb over a period of several weeks. Full resorption of this device is expected.
Measured: 0-3 months

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 May 2021; AzTrials last refreshed its copy on 6 Nov 2026.
