About this study

Official title: Comparison of Myringoplasty Using Porcine Small Intestinal Submucosa (Biodesign) Versus Autologous Grafts (Perichondrium, Temporalis Fascia, Cartilage, or Fat) for Tympanic Membrane Perforation Closure: A Retrospective Cohort Study

The goal of this observational, retrospective study is to learn whether a ready-made graft patch (Biodesign, made from porcine small intestinal submucosa) works as well as a participant's own tissue graft (such as tragal perichondrium or temporalis fascia) to close a hole in the eardrum (tympanic membrane perforation). The main questions this study aims to answer are:

Does the eardrum hole close after surgery, and is the closure rate similar between Biodesign and autologous tissue grafts?

Read more

Do participants have similar hearing improvement after surgery (measured by the air-bone gap, a common hearing test measure)?

Is the operating time different between the graft types?

Are there differences in complications or adverse reactions?

Study hypothesis: Biodesign will have a similar eardrum closure rate compared with autologous tissue grafts, with similar hearing improvement and low complication rates, and may be associated with a shorter operating time.

How the study will work: Investigators will review medical records of participants who had myringoplasty/tympanoplasty for eardrum perforation in the department between 2020 and 2024. Data already recorded as part of usual care will be collected, including: pre-surgery eardrum findings (size and location of the perforation) and hearing tests; operative details (technique and operating time); and follow-up at about 3 months, including an ear exam to confirm closure and check for adverse reactions, plus a hearing test. Participants will be excluded if they have other ear conditions (such as cholesteatoma, otosclerosis, or tympanosclerosis), if the eardrum was described as flaccid, or if follow-up or post-operative hearing data are missing.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • tympanoplasty using BiodesignProcedure or surgery

    Also called Porcine small intestinal submucosa graft

    Porcine small intestinal submucosa graft (Biodesign) A commercially available extracellular matrix sheet made from porcine small intestinal submucosa (SIS), supplied as a sterile, freeze-dried soft-tissue graft. The surgeon uses the SIS sheet as the tympanic membrane graft to seal the perforation during myringoplasty.

  • tympanoplasty using autologous tissue graftProcedure or surgery

    Also called Tragal perichondrium, Temporalis fascia

    A graft made from the participant's own tissue harvested at surgery and used to repair the tympanic membrane perforation. In this dataset, autologous grafts are primarily tragal perichondrium and temporalis fascia. This approach requires a donor-site harvest and the graft is shaped and placed to cover the perforation

BiodesignParticipants with tympanic membrane perforation who underwent myringoplasty/tympanoplasty using a porcine small intestinal submucosa (Biodesign) graft for perforation repair.

Autologous graftsParticipants with tympanic membrane perforation who underwent myringoplasty/tympanoplasty using the participant's own tissue for perforation repair (tragal perichondrium, temporalis fascia, cartilage, or fat), as documented in the operative report.
Receives: Procedure: tympanoplasty using autologous tissue graft

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Tympanic membrane perforation status (closed vs not closed)

    Tympanic membrane status will be determined from postoperative ear examination (otoscopy or microscopy) documented in the medical record. The measure is the proportion of participants with an intact tympanic membrane (no residual perforation) at the follow-up visit closest to 3 months after surgery.

    Measured: Three months after surgery

Secondary outcomes (1)
  1. Change in air-bone gap (operated ear)

    Air-bone gap will be calculated from standard pure-tone audiometry for the operated ear before surgery and at the follow-up visit closest to 3 months after surgery. The outcome is the change in air-bone gap from baseline to follow-up (in decibels).

    Measured: Three months after surgery

The record lists 1 site in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Tympanic membrane perforation status (closed vs not closed) (time frame: Three months after surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07698171, which also lists 5 linked publications.

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 13 Jul 2026.
