Reaction from a long-term ventilating tube. (Otoscopic Clinic).The otoscopic view shows a right ear in which a ventilating ventilating Natural or mechanically induced movement of fresh air into or through an enclosed space. The hazards of poor ventilation were not clearly understood until the early 20th century. Expired air may be laden with odors, heat, gases, or dust. tube had been in place for more than 2 years. There is evidence of chronic inflammation and pus pus, thick white or yellowish fluid that forms in areas of infection such as wounds and abscesses. It is constituted of decomposed body tissue, bacteria (or other micro-organisms that cause the infection), and certain white blood cells. . The pars tensa is injected from inflammation. A 30% central perforation of the pars tensa represents the enlargement of the original myringotomy myringotomy /my·rin·got·o·my/ (mi-ring-got´ah-me) tympanotomy; creation of a hole in the tympanic membrane, as for tympanocentesis. myr·in·got·o·my n. opening.

In the adult, tubes of this type can last indefinitely without difficulty. In children, however, it is not uncommon to see the development of granulation tissue and enlargement of the myringotomy any time a tube has been in place for more than 1 year. In the case pictured here, there is no longer a reason to leave the tube in the ear, and it should be removed. The resulting perforation can be left untreated until the surgeon feels comfortable that serous fluid will not return. Myringoplasty is necessary to repair the ear.
