Abstract: Amniotic membrane has been used as wound dressing for more than 100 years. With the development of the preservation and preparation techniques, amniotic membrane is widely used in ophthalmology, burns, plastic surgery, dentistry, and neurosurgery. In recent years, as more and more amniotic membrane is used in chronic wounds, it will be a new treatment method for wounds. This paper is a brief review about advances in preparation and clinical application of amniotic membrane graft.
