Selfmembranes

Selfmembranes, also known as autologous membranes, are biological materials derived from a patient's own body that are used in medical applications. These membranes are typically harvested from tissues such as the skin, fascia, or pericardium. The primary advantage of using autologous membranes is the absence of immune rejection, as the material is genetically identical to the recipient. This minimizes the risk of allergic reactions and the need for immunosuppressive drugs.

In surgical procedures, selfmembranes serve as grafts or barriers. They can be employed in reconstructive surgery to repair defects, such as those resulting from trauma or cancer resection. For instance, skin grafts from a patient's own body are a common method for treating burns. Fascial grafts can be used to reinforce weakened tissues, particularly in hernia repair or abdominal wall reconstruction. Pericardial grafts, taken from the sac surrounding the heart, are utilized in cardiac surgery, often for valve repair or replacement.

The harvesting of selfmembranes is a surgical procedure itself, and careful handling is required to ensure the viability and integrity of the tissue. While the benefits of autologous materials are significant, the process can add complexity and time to a surgery. Furthermore, the availability of suitable donor sites on the patient's body can sometimes be a limiting factor. Despite these considerations, selfmembranes remain a valuable tool in regenerative medicine and various surgical specialties due to their inherent biocompatibility.
