DNA replication is the process of producing two identical replicas from one original DNA molecule. This biological process occurs in all living organisms and is the basis for biological inheritance.
Ear Tubes. Recurring ear infections or fluid build-up in the middle ear may require the temporary placement of tubes in the ear. Ear tube surgery involves a very small incision in the eardrum, which is a thin layer of tissue separating the outer and middle ear. The procedure is known as a myringotomy or tympanostomy. A small, plastic tube shaped like a hollow spool (a tympanostomy tube) is then inserted into the eardrum to keep the middle ear drained and ventilated. The tubes remain for 6 months to several years, and eventually fall out or are removed by a doctor.
Tympanoplasty. Tympanoplasty is a procedure performed for reconstruction of the eardrum and/or the small bones (ossicles) of the middle ear. Tympanoplasty can be performed entirely through the ear canal or may require an incision behind the ear.Surgery that includes the mastoid bone behind the ear is known as a tympanomastoidectomy.ympanoplasty surgery is either performed completely through the ear canal or through an incision behind the ear. An operating microscope and micro-instrumentation are used for all parts of the surgery.
