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.
Tympanic part of the temporal bone squama and mastoid part, and forms the anterior boundary of the tympanomastoid fissure. Its upper border fuses laterally with the back of the postglenoid process, while medially it bounds the petrotympanic fissure. The medial part of the lower border is thin and sharp; its lateral part splits to enclose the root of the styloid process, and is therefore named the "vaginal process". The central portion of the tympanic part is thin, as it gives rise to the bony inner two-thirds of the ear canal, and in 5 - 20% of skulls the lower surface is perforated by a hole, the
