  • MeroGel Bioresorbable Ear Packing from Medtronic

MeroGel Ear Packing

MeroGel bioresorbable ear packing is a convenient aid to wound healing after middle ear surgery and other otologic procedures. MeroGel ear packing helps to separate mucosal surfaces and control minimal bleeding.

Ear Packing that Aids Healing

MeroGel® bioresorbable ear packing gradually dissolves and may be used during canalplasty, tympanoplasty, myringoplasty, and stapedectomy and mastoid procedures.

It’s made from esterified hyaluronic acid or HYAFF®, which helps keep the surgical site moist and aids wound healing.1-4

How Is It Used?

Small pieces of MeroGel ear packing are pulled away, rolled into spheres, hydrated with a sterile solution, and placed in the middle ear cavity. The biomaterial doesn’t swell and excess fluid may be suctioned out of the packing (Fig. 1).

After hydration, MeroGel ear packing typically dissolves in about six weeks. In the external ear canal, MeroGel ear packing will dissolve in approximately two weeks, if kept hydrated (Fig. 2).

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 and help reduce fibrous scarring.1-4

Additional Ear Packing and Patching Products
