Use of human amniotic membrane in otolaryngologic practice

Human amnion is a readily available allograft with low antigenicity, high antimicrobial potential, and the ability to foster epithelialization. We have used human amniotic membrane in our department for replacing nasal mucosa in Rendu-Osler-Weber disease, as tympanic membrane grafts, and for covering head and neck sites after flap necrosis. Our experience shows moderate success for management of severe epistaxis and excellent results in covering surfaces after flap necrosis. Use of amnion in eardrum perforations was unsuccessful and was discontinued. Properties of human amniotic membrane are listed and its application in the otolaryngologic practice is reviewed.
