Myringoplasty is a surgery done to repair perforation (a hole in the eardrum), usually caused by infection or trauma. Myringoplasty also restores hearing loss in certain cases of tinnitus. Myringoplasty should not be performed on children below 3 years of age. Also if the patient has one of the ears dead or found active discharge from the middle ear of the patient and uncontrolled nasal allergy. The surgery is done under general or local anesthesia. The surgeon makes an incision above or behind the ear to access the eardrum. The technique involves freshening the edges of the perforation to promote healing and placing a carefully trimmed graft lateral o patch-up the perforated area.
Myringoplasty is effective in approximately 60% of cases in closing the tympanic membrane perforation.
Two techniques to patch up the area are the underlay and the overlay technique.
- Underlay technique: The temporal fascia is grafted. An incision is created on the edge of the perforation and a hoop of epithelium is removed. A strip of membrane layer is removed from the inner aspect of the perforation. The middle ear is packed with gel-foam soaked with an antibiotic.The edges of the graft should extend beneath the margins of the perforation and a small part should also extend over the posterior canal wall. The tympanomeatal flap is then replaced.
- Overlay Technique: The temporal fascia is harvested. An incision is made to raise medial meatal skin with tympanic membrane epithelium. The graft is positioned on the outer surface of the tympanic membrane and a slit is made to tuck it underneath the handle of malleus. The ear is packed with gel-foam and antibiotics, and the incision is closed.
