Tympanic Membrane Perforation Clinical Trial
Official title:
Comparison of Tympanoplasty Surgery Outcome Using Amniotic Membrane and Autologous Temporalis Fascia: A Randomized Clinical Trial Study
The tympanic membrane separates the middle and the outer ear from each other and consists of
three layers. The outer layer is covered with squamous epithelium, a thick basement membrane
in the middle and an inner Mucosal layer. Rupture of the tympanic membrane is common cause of
hearing loss.
In spite of the ability to spontaneously healing of the tympanic membrane, chronic tear of
the eardrum in the absence of its spontaneously healing indicates surgical management. These
surgeries are performing using various materials including fascia, cartilage, fats,
pericardium and paper patch. It has proven that using different materials results in outcome
and postoperative complications. The criteria of the best graft material includes
availability, preservability, manageability, and acceptance rate to the hosts. Human amniotic
membrane is preservable. Also, there isn't significant immunologic reactions against such
graft material. So, choosing the best graft for Tympanoplasty surgery decreases
complications, hospitalizations after surgery, and costs, consequently.
Up to now, limited studies have been conducted on the patients who were used amniotic
membrane in the surgical reconstruction. There are different outcomes and complications which
depend on the size of the rupture and the problems associated with the surgical conditions.
Considering that it can reduce the surgical time and cost of surgery, and with its high
success rate, it can even be used as a substitute for conventional methods. The aim of this
study was to compare the result of surgical repair of the tympanic membrane using membrane
amniotic and surgical Tympanoplasty with Autologous fascia. Here the investigators reported
on 30 patients who underwent Typmanoplasty with amniotic membrane and Temporalis fascia
grafting.
