We report the first prospective evaluation of middle ear barotrauma in experienced recreational scuba divers. In this pilot study, tympanometric and otoscopic evaluations were performed daily on two experienced scuba divers engaged in multi-day repetitive diving. Middle ear pressures decreased in proportion to diving frequency, demonstrating eustachian tube dysfunction which promptly reversed upon cessation of diving Otoscopic evidence of traumatic injury to the middle ear occurred in proportion to diving frequency, and also readily reversed upon cessation of diving. Tympanic membrane compliance remained normal, often despite pronounced otoscopic abnormalities. Otologic symptoms and impairment of acuity were not observed. Tympanometry appears to be a valuable modality for the verification of middle ear hemorrhage or tympanic membrane rupture. This preliminary data should assist investigators in planning more comprehensive studies of middle ear barotrauma, including clinical trials of treatment and prophylactic interventions for this common condition.
我们报告了对有经验的休闲水肺潜水员中耳气压伤的首次前瞻性评估。在这项试点研究中，每天对两名参与多日重复潜水的有经验的水肺潜水员进行鼓室图和耳镜检查评估。中耳压力随潜水频率成比例下降，表明咽鼓管功能障碍，潜水停止后迅速恢复正常。中耳创伤性损伤的耳镜检查证据随潜水频率出现，潜水停止后也很容易恢复。鼓膜顺应性保持正常，尽管耳镜检查有明显异常。未观察到耳部症状和听力损害。鼓室图似乎是验证中耳出血或鼓膜破裂的一种有价值的方法。这些初步数据应有助于研究人员规划对中耳气压伤更全面的研究，包括针对这种常见病症的治疗和预防性干预的临床试验。
