EpiDisc and MeroGel QuickGel

EpiDisc Otologic Lamina and MeroGel QuickGel are made from esterified hyaluronic acid.  

  • EpiDisc is a thin, implantable scaffold with thousands of microperforations that help facilitate cell proliferation, tissue regrowth, and drainage while the tympanic membrane perforation is healing
  • MeroGel QuickGel dressing changes into a viscous transparent hyaluronan gel that conforms to the surface of the tympanic membrane when hydrated

Hyaluronic Acid and Middle Ear Surgery

In middle ear surgery, biocompatible1-7 hyaluronic acid has been shown to improve the natural healing of the mastoid cavity following tympanoplasty and help reduce fibrous scarring.1-4

Tympanic membrane (TM) perforations are common and usually follow episodes of acute otitis media, ventilation tube insertion, or trauma.

Symptoms can include conductive hearing loss, aural fullness, pain, tinnitus, and exudate. Some patients with TM perforations may by asymptomatic.

In many cases, the TM perforation heals on its own. Tympanic membrane perforations that do not heal spontaneously, even small ones, may require surgical repair, particularly when they are associated with hearing loss or recurrent infection. Furthermore, patients must be careful to avoid exposing the ear to water and possible infection.
