for Middle Ear Surgery and Other Otologic Procedures
EpiFilm and EpiDisc Otologic Laminae
EpiFilm and EpiDisc Otologic Laminae are bioresorbable film scaffolds with thousands of microperforations that help the body repair and regrow tissue after middle ear surgery.
EpiFilm® and EpiDisc® Otologic Laminae are bioresorbable, implantable ear packing and patching devices composed of esterified hyaluronic acid (HYAFF®).
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

EpiFilm® and EpiDisc® Otologic Laminae are unique bioresorbable, implantable ear packing and patching devices composed of esterified hyaluronic acid, or HYAFF®. The thin film scaffold acts as a temporary matrix for cell proliferation, working with the body’s natural healing process to repair and regrow damaged tissue.
Thousands of microperforations enable cells to migrate across and through the scaffold, populating both sides simultaneously and facilitating drainage.
By providing a multilayer, thick cell structure in a shorter period of time, EpiFilm and EpiDisc Otologic Laminae physically enhance the epithelialization process. In approximately 6-8 weeks, the temporary scaffold is resorbed.
In middle ear surgery, hyaluronic acid has been shown to improve the natural healing of the mastoid cavity following tympanoplasty and help reduce fibrous scarring.1-4
Hyaluronic acid is a linear polysaccharide and naturally occurring constituent of the extracellular matrix.
It plays a significant role in the body during the repair process, mediating cell adhesion, differentiation, motility, and blood vessel growth. Hyaluronic acid has a well-established biocompatibility profile.1-7
