Aim To determine the loudness of suctioning in the ear canal with different-sized suctions and various mediums. Aural microsuctioning is commonly used in the otolaryngologist's office setting for cerumen removal and aural toilet. We hypothesize that the intensity of the sound would increase with increasing viscosity of the medium and increasing suction diameter. Methods The intensity of the sound generated was measured while suctioning air, water, and yogurt on cadaveric temporal bones with size 7 and 5 Frazier suctions. This was performed with one measurer and one operator. Under otomicroscopy, the operator would suction the ear canal and the measurer would record the intensity of the sound with a sound decibel meter placed at the lateral and posterior external auditory canal. Data was collected with two separate operators and measurers to aid with inter-rater reliability. Results There was a total of 240 repeated observations (10 cadavers, 3 mediums, 2 suction devices; 2 investigators). The range of the maximum peak intensity ranged from 63.0 dB to 100.0 dB. The lowest peak intensity of decibels was recorded in air with the size 5 Frazier suction; and the highest measured was with the size 5 Frazier suction in yogurt. Statistically significant differences were found only in the measurements in air. Conclusion Our investigation found that increasing peak sound intensities were generated by increasing the viscosity of the fluid medium that was being suctioned. However, the smaller sized diameter suction actually generated louder sound intensities than the larger diameter suction with higher viscosity fluid media, but this was not statistically significant.
确定使用不同尺寸的吸引器以及在各种介质下耳道吸引时的响度。耳显微吸引术常用于耳鼻喉科诊室清除耵聍和进行耳部清洁。我们假设声音强度会随着介质粘度的增加和吸引器直径的增大而增加。方法：使用7号和5号Frazier吸引器在尸体颞骨上对空气、水和酸奶进行吸引时，测量产生的声音强度。由一名测量员和一名操作员进行操作。在耳显微镜下，操作员对耳道进行吸引，测量员使用置于外耳道外侧和后方的声级计记录声音强度。数据由两名不同的操作员和测量员收集，以提高评分者间的可靠性。结果：总共进行了240次重复观察（10具尸体，3种介质，2种吸引装置；2名研究者）。最大峰值强度范围为63.0分贝至100.0分贝。分贝最低的峰值强度是在使用5号Frazier吸引器吸引空气时记录到的；测量到的最高值是在使用5号Frazier吸引器吸引酸奶时。仅在空气吸引测量中发现了统计学上的显著差异。结论：我们的研究发现，被吸引的流体介质粘度增加会产生更高的峰值声音强度。然而，较小直径的吸引器在吸引较高粘度流体介质时，实际上产生的声音强度比大直径吸引器更大，但这在统计学上并不显著。
