Use Of HAM In Surgical Treatment Of TMJ

Abstract

Surgery to correct disorders of the TMJ has been performed and documented since the mid-nineteenth century. Facts shows that reversible non-surgical treatment can improve the situation of patients with internal pathological conditions of the joint, but still some patients require surgical intervention. We have several techniques to treat TMJ derangements of which is TMJ arthroplasty with the interposition of autograft (e.g. dermis, temporal fascia, or cartilage). Recently, with the inception of the 21st century, HAM is observed to be a promising material used in treatment of different surgical fields. The HAM is the inner layer of the placenta which surrounds the baby during pregnancy. The HAM has been shown to have anti-fibrotic, anti -inflammatory, anti-angiogenic and anti-microbial properties. Also, it is considered encouraging because of its transplant structure and the ability to provide an excellent substrate for growth, migration, and adhesion of cells. This project was triggered by a study to demonstrate whether the HAM could prevent TMJ reankylosis in randomized rabbit models (2010). Case Report: A severe TMJ degeneration was diagnosed with a 48-years old woman and surgical treatment was necessary. Cryopreserved HAM patch was applicated within the joint space as a disc-replacing film. The patient reported an overall improvement in chewing as well as the absence of pain. The aim of this article is to be regarded as initial spadework and should motivate other institutions to intensify their clinical research in this field. As to prevent recurrence of TMDs.
