Do-it-yourself ear vacuum kits (ear vacs) have recently been introduced as an effective method of earwax removal. This study assesses the efficacy of ear vacs in comparison with a conventional mechanical method of earwax removal, the Jobson-Horne probe.
Forty healthy relatives who had accompanied family members to orthopaedic and haematology clinics were screened with otoscopy. Sixteen participants with earwax were selected.
(i) Weight of earwax removed, (ii) proportion of tympanic membrane visible before and after each intervention, (iii) participants' subjective assessment of any improvement in hearing. Suction pressure generated by the ear vac was also compared with that of microsuctioning.
No earwax was removed with the ear vac but the Jobson-Horne probe was significantly more effective at removing a greater weight of earwax (P < 0.001, mean weight 92.4 mg). There was no improvement in visibility of the tympanic membrane after the ear vac but the Jobson-Horne probe restored visibility to 100% (P < 0.001). No participant felt that there was an improvement in their hearing after the ear vac, but the majority (88%) reported an improvement in their hearing after the Jobson-Horne probe.
A Jobson-Horne probe is significantly more effective than an ear vac for the removal of earwax.
自行使用的耳部真空套件（耳用真空装置）最近被作为一种有效的耵聍清除方法引入。本研究评估耳用真空装置与传统的机械耵聍清除方法（乔布森 - 霍恩探针）相比的疗效。
对40名陪同家庭成员前往骨科和血液科诊所就诊的健康亲属进行耳镜检查筛选。选取了16名有耵聍的参与者。
（i）清除的耵聍重量，（ii）每次干预前后鼓膜可见比例，（iii）参与者对听力改善的主观评估。还比较了耳用真空装置产生的吸力与微型吸引器产生的吸力。
耳用真空装置未清除任何耵聍，但乔布森 - 霍恩探针在清除更多重量的耵聍方面明显更有效（P < 0.001，平均重量92.4毫克）。耳用真空装置使用后鼓膜可见度没有改善，但乔布森 - 霍恩探针使鼓膜可见度恢复到100%（P < 0.001）。耳用真空装置使用后没有参与者感觉听力有所改善，但大多数（88%）参与者报告在使用乔布森 - 霍恩探针后听力有所改善。
乔布森 - 霍恩探针在清除耵聍方面比耳用真空装置明显更有效。
