Use of Human Dehydrated Amnion Chorion Allograft in Laryngectomy/Pharyngectomy

This trial aims to determine if intra-operative use of human dehydrated amnion chorion allograft improves post-operative patient healing outcomes.

Use of Human Dehydrated Amnion/Chorion (DHACM) Allograft in Partial Nephrectomy

After partial nephrectomy, kidney function decreases by about 10% overall and by about 20% in the operated kidney. This is primarily due to the loss of healthy parenchymal volume during re...

Addition of Dehydrated Human Amnion-Chorion Membrane During Scaling and Root Planing

Hypothesis: There will be an additional reduction of pocket depth and gain of clinical attachment when dehydrated human amnion-chorion membrane (dHACM) is placed into the periodontal disea...

The Use of Human Amnion/Chorion Membrane and Umbilical Cord Grafts for Treatment of a Scalp Wound With Exposed Bone.

Medical and Biotech [MESH] Definitions

INFLAMMATION of the placental membranes (CHORION; AMNION) and connected tissues such as fetal BLOOD VESSELS and UMBILICAL CORD. It is often associated with intrauterine ascending infections during PREGNANCY.

The thin layers of tissue that surround the developing embryo. There are four extra-embryonic membranes commonly found in VERTEBRATES, such as REPTILES; BIRDS; and MAMMALS. They are the YOLK SAC, the ALLANTOIS, the AMNION, and the CHORION. These membranes provide protection and means to transport nutrients and wastes.

An extra-embryonic membranous sac derived from the YOLK SAC of REPTILES; BIRDS; and MAMMALS. It lies between two other extra-embryonic membranes, the AMNION and the CHORION. The allantois serves to store urinary wastes and mediate exchange of gas and nutrients for the developing embryo.

The outermost extra-embryonic membrane surrounding the developing embryo. In REPTILES and BIRDS, it adheres to the shell and allows exchange of gases between the egg and its environment. In MAMMALS, the chorion evolves into the fetal contribution of the PLACENTA.

The innermost membranous sac that surrounds and protects the developing embryo which is bathed in the AMNIOTIC FLUID. Amnion cells are secretory EPITHELIAL CELLS and contribute to the amniotic fluid.
