Artificial ventilation of an under-ventilated middle car by means of a tympanostomy tube still is a subject to controversy. We present a series of 149 cars of which tympanostomy tubes were inserted, the audiometric gain and the complications we have observed. 88.3 % of the ears had air-bone gaps minimized at the postoperative first month. The overall rate of complications was found to be 10.7 %, with 4.2% as temporary complications. We believe that insertion of a ventilation tube still is the treatment of choice for otitis media with effusion, at least for selected cases.
