Procedures and Techniques for Tympanoplasty and Ossicular Reconstruction
View surgical techniques for tympanoplasty, ossicular reconstruction, and other procedures using MeroGel Ear Packing, EpiDisc Otologic Lamina, and the Roberson Stapes Prosthesis.
Technique: Krueger "HAT" Tympanoplasty
EpiDisc placed on promontory, while small pieces of hydrated MeroGel help support tympanic membrane graft
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
Fig. 1: Small pieces of MeroGel are rolled into spheres, hydrated, and placed in middle ear cavity
Figure 1
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
Figure 2
After hydration, MeroGel ear packing typically dissolves in approximately six weeks.
In the external ear canal, MeroGel ear packing will dissolve in approximately two weeks, if kept hydrated.
