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.
Eardrops may be prescribed if there is fluid in the ear. The ear should be kept dry for two weeks after the procedure, with no fluid entering the ear until the myringotomy site in the eardrum is healed. Myringotomy and insertion of a tympanoplasty tube as treatment for otitis media.From Frazier et al., 2000.ometimes, as in the case of serous otitis media, a ventilating tube called a grommet is inserted to permit continuous ventilation and avoid a chronic middle ear problem with fluid accumulation, pain, and loss of hearing.
