[Indications for the insertion of ventilating tubes in the mucotympanum of the child].

The influence of adenoidectomy, myringotomy and lavage of the middle ear was studied in children suffering from secretory otitis. The children were controlled by audiograms and tympanograms over a one-year period of time. 89 percent of all children showed normal values one year following surgery, 11 percent had still high negative middle ear pressures and conductive hearing loss. We think that these children only are candidates for ventilating tubes (grommets).
