This study sought to monitor changes in middle ear pressure with tympanometry after a simplified home politzerization maneuver in children who had excessive negative intratympanic pressure and/or serous otitis media. The mean middle ear pressure for 23 children was -201 mm H2O, whereas seven subjects displayed a flat tympanogram that was consistent with the medical diagnosis of serous otitis media. Middle ear pressure measurements with tympanometry at five and ten minutes after politzerization indicated successful tympanic ventilation in 91% and 85% of the ears, respectively. For children with negative intratympanic pressures of -250 mm H2O, data suggested that ventilation was sustained for at least 30 minutes. In general, results lend support for using home politzerization as an alternative or associative treatment in children with high negative pressure and/or serous otitis media.
本研究旨在监测进行简化家庭波利策法操作后，中耳负压过高和/或患有浆液性中耳炎的儿童通过鼓室图测量的中耳压力变化。23名儿童的平均中耳压力为-201毫米水柱，而7名受试者的鼓室图呈平坦型，这与浆液性中耳炎的医学诊断一致。波利策法操作后5分钟和10分钟通过鼓室图测量中耳压力，结果显示分别有91%和85%的耳朵实现了成功的鼓膜通气。对于中耳负压为-250毫米水柱的儿童，数据表明通气至少持续了30分钟。总体而言，研究结果支持将家庭波利策法作为中耳负压过高和/或浆液性中耳炎儿童的替代治疗或联合治疗方法。
