| Abstract: | Summary We examined 143 ears in 89 patients before and after septum operation. We found that in 56.6% of the patients with negative pressure in the middle ear, this negative pressure was reduced by the operation. This result was supported by rhinomanometric examinations. The tubal resistance and the ability of opening the tubes actively were not influenced. This result indicates an improved pressure compensation between nose and middle ear after the operation, when a tympanic underpressure is present. |
