In 61 cerebral palsied children tympanometry was used for indirect registration of middle ear pressure. One quarter of the patients showed pressure values below -50 mm H2O. Tympanometry was done also after the Valsalva and Politzer manoeuvres, which were performed consecutively. In 22 ears there was no pressure change after both, the Valsalva and Politzer manoeuvre. In 6 ears there was no change of the original negative middle ear pressure after Politzerisation. No correlation could be found between a) type of cerebral palsy and b) severity of oral sensorimotor disturbance and negative middle ear pressure. Nevertheless there was a significant smaller pressure-change induced by the Valsalva manoeuvre in the orally severely handicapped group compared to the group with only minor or no oral pathology. Oral sensorimotor handicaps seem to predispose to disturbances of the middle ear system. The Politzer manoeuvre can be used successfully in the majority of cerebral palsied children.
对61名脑瘫儿童进行了鼓室导抗图检查，以间接记录中耳压力。四分之一的患者压力值低于-50 mm H₂O。在连续进行瓦尔萨尔瓦动作和波利策尔手法后也进行了鼓室导抗图检查。在22只耳朵中，瓦尔萨尔瓦动作和波利策尔手法后压力均无变化。在6只耳朵中，波利策尔手法后原有的中耳负压没有变化。在a）脑瘫类型和b）口腔感觉运动障碍严重程度与中耳负压之间未发现相关性。然而，与仅有轻微口腔病变或无口腔病变的组相比，重度口腔功能障碍组中瓦尔萨尔瓦动作引起的压力变化明显较小。口腔感觉运动障碍似乎易导致中耳系统紊乱。波利策尔手法在大多数脑瘫儿童中可成功应用。
