title: [Experiences with polyethylene ventilation tubes in children with recurrent middle ear inflammation (author's transl)].
abstract: Middle-ear ventilation tubes (of the Sheehy modification) were placed in 401 ears of 209 children under 16 years of age as treatment for recurrent middle-ear infection. The same procedure was later required in 26% of the cases studied because of further recurrence of middle-ear infection. In four per cent of all patients studied, the ventilating tube failed to cure middle ear disease in spite of controlled concomitant antibacterial therapy. In these cases, an early extrusion of the tube was commonly found. Among all patients, the tube was spontaneously extruded in 76 per cent of the ears, whereas the intubation time was longer than half a year in 53 per cent of the cases. No complications from insertion of the ventilation tubes was seen in the present series of patients. The tympanic membrane was found to be normal in 71 per cent of all cases when follow-up examination was obtained three months after completion in intubation. However, a permanent tympanic membrane perforation was found in five ears (1% of patients). The present study has confirmed the usefulness of middle-ear ventilation tubes, particularly in patients with recurrent middle-ear infections.
