EpiFilm Otologic Lamina

After a tympanoplasty, EpiFilm Otologic Lamina has been shown to aid the healing of the mastoid cavity. The 2.5 cm x 2.5 cm matrix is useful for myringoplastic and tympanoplastic procedures, such as:

  • Covering exposed ear canal walls
  • Reconstruction of the tympanic membrane when used with fascia or other tissue graft techniques
  • Lining the mastoid cavity

EpiDisc Otologic Lamina

EpiDisc Otologic Lamina is a pre-cut 8.0 mm disc of EpiFilm lamina, packaged 2 per box. This makes it ideal for use during tympanoplasties or repairing tympanic membrane perforations.

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
