Tympanic membrane retraction the nose with laser or balloon dilatation is being evaluated as a potential treatment for tympanic membrane retraction. Excision of the retracted segment of an eardrum, with or without placement of a tympanostomy tube has been advocated. Healing of the area can result in a more normal eardrum. Laser therapy has been used to shrink and stiffen retraction pockets. Tympanoplasty is the surgical technique of removal of the retracted area from the middle ear and reconstruction of the tympanic membrane. Some surgeons use cartilage (taken from the outer ear) to stiffen the eardrum with the aim of preventing further retraction.
Serous membrane Serous membrane In anatomy, serous membrane (or serosa) is a smooth tissue membrane consisting of two layers of mesothelium, which secrete serous fluid. The inner layer that covers organs (viscera) in body cavities is called the visceral membrane. A second layer of epithelial cells of the serous membrane, called the parietal layer, lines the body wall. Between the two layers is a potential space, mostly empty except for a few milliliters of lubricating serous fluid that is secreted by the two serous membranes. The Latin anatomical name is "tunica serosa". Serous membranes line and enclose several body cavities, known as
