Swallowing disturbances are common after neurological disease and oropharyngeal tumor resection. In this case the oral stage is often affected. So far the clinical evaluation of the oral phase is limited. Recently the role of pressure changes during oropharyngeal swallowing has been pointed out, but until now there are not enough data. Thereby 52 healthy adults aged between 20 and 45 years were examined using an oral shield (Silencos(®), Bredent, Senden, Germany) connected to a digital manometer (GDUSB 1000(®), Greisinger electronics, Regenstauf, Germany) able to record pressures in a range of 2,000 to -1,000 mbar at a frequency of 1 kHz. Three swallowing conditions were measured: an active bolus intake (ABI) of water, a passive bolus application of a water-bolus (PWA) and a passive application of a gel-bolus (PGA). We found negative pressures with a median value of -278.9 mbar during ABI, of -24.2 mbar during PWA and of -29.4 mbar during PGA. Significant differences in pressure amplitudes and the pressure pattern were observed depending on the kind of bolus application and its consistency. The used test presents a simple and easy to handle method to assess the oral phase of swallowing.
吞咽障碍在神经疾病和口咽肿瘤切除术后很常见。在这种情况下，口腔期通常会受到影响。到目前为止，口腔期的临床评估还很有限。最近，人们已经指出口咽吞咽过程中压力变化的作用，但到目前为止，相关数据还不够充分。因此，我们使用与数字压力计（GDUSB 1000(®)，Greisinger electronics，Regenstauf，德国）相连的口腔保护器（Silencos(®)，Bredent，Senden，德国）对 52 名年龄在 20 岁至 45 岁之间的健康成年人进行了检查，该压力计能够以 1 kHz 的频率记录 2,000 毫巴至-1,000 毫巴范围内的压力。测量了三种吞咽条件：主动吞咽水（ABI）、被动吞咽水球（PWA）和被动吞咽凝胶球（PGA）。我们发现 ABI 时的中位负压为-278.9 毫巴，PWA 时为-24.2 毫巴，PGA 时为-29.4 毫巴。根据球囊应用的类型和一致性，观察到压力幅度和压力模式存在显著差异。所使用的测试提供了一种简单易用的方法来评估吞咽的口腔期。
