MeroGel Technique

Technique: MeroGel Bioresorbable Ear Packing

MeroGel® bioresorbable ear packing is used to separate mucosal surfaces and help minimize adhesion formation following a variety of otologic procedures.

This ear packing is made from esterified hyaluronic acid or HYAFF®, which helps keep the surgical site moist and aids wound healing.1-4

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. 2: MeroGel ear packing typically dissolves in about 6 weeks after hydration, or 2 weeks if kept hydrated

After hydration, MeroGel ear packing typically dissolves in approximately six weeks.
