[The problems of simultaneous tympanoplasty and adeno- tonsillectomy (author's transl)]

The effect of adento-tonsillectomy on tube function and middle-ear ventilation was measured by tympanometry and manometry. It was found, that after adenotomy considerable negative pressure values may develop in the middle ear. In about one third of all cases five to six days after operation the tube function was not yet normal again. After tonsillectomy alone only a few of the operated children has slight negative pressure values. Adenotomy and tympanoplasty should not be achieved simultaneously.
