A myringoplasty is a surgical procedure aimed at repairing a perforation, or hole, in the eardrum, also known as the tympanic membrane. This operation is specifically confined to the drumhead and the donor area, which is the site from where tissue may be harvested for the repair. The procedure can be performed using two primary approaches: through the ear canal, which is a less invasive method, or through a post-auricular incision, which involves making an incision behind the ear. During the surgery, the surgeon carefully exposes and inspects the hole in the eardrum. The tissue surrounding the perforation is meticulously rimmed until bleeding occurs, which can promote healing by encouraging the edges of the hole to come together. In cases where the edges do not naturally heal, a patch may be necessary. Typically, a fat graft is harvested from the patient, which is then prepared for placement. To support the graft, absorbable sponge material may be inserted into the middle ear behind the hole. The graft is subsequently placed over the perforation, and an absorbable sponge is positioned in the ear canal over the graft to secure it in place. Finally, the ear is packed with gauze to protect the surgical site and facilitate healing.
