Bioresorbable Ear Packing and Patching for Middle Ear Surgery

After middle ear surgery, our bioresorbable ear packing and patching products aid wound healing and help prevent adhesions.1 Ear packing and patching typically is performed with canalplasty, tympanoplasty, myringoplasty, and stapes and mastoid procedures.

Most Common Middle Ear Surgery Complications
The most common postoperative complications from middle ear surgery include middle ear adhesions/fibrosis, dense fibrous capsule formation in the middle ear, and chronic granular inflammation of the tympanic membrane graft and canal wall.

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

Biomaterials and Biocompatibility

Medtronic utilizes various biomaterials in ENT products, such as our ear packing and patching devices, nasal packing, ossicular prostheses, and ventilation tubes. Biomaterials are rigorously tested for biocompatibility -- cytotoxicity and the body's reaction to the biomaterial, as well as how the biomaterial reacts to the body.

For ear packing and patching, our MeroGel®, MeroGel Injectable, EpiDisc® and EpiFilm®, and EpiDisc TM Perf Patch Kit utilize esterified hyaluronic acid, or HYAFF®.

What Is Hyaluronic Acid?

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 used in a plethora of products for many medical specialties.

  • It's a linear polysaccharide and naturally occurring constituent of the extracellular matrix
  • It plays a significant role during the repair process: mediating cell adhesion, differentiation, motility, and blood vessel growth
  • It has a well-established biocompatibility profile1-7
