Fifteen ears of 12 children with otitis media with effusion were studied by myringotomy. Their tubal functions were examined after the procedure. Without aspiration of mucus in the tympanic cavity, 3 of 6 ears showed no mucus 2 hours after myringotomy. Two days after the procedure all of the nine ears became dry. Ciliary clearance of their tubes were not good and equilibration of negative pressure were totaly disturbed. We concluded that the reduction of negative middle ear pressure by myringotomy restores no ciliary function but the muscular one to clear the middle ear effusion through the tube.
