摘要
这篇社论探讨了鼓室测压法中 "在正常范围内"(WNL)的概念,重点关注其在识别交变性眩晕(AV)和地面交变性眩晕(GLAV)等疾病方面的局限性。鼓室测压法是一种简单的诊断仪器,可测量中耳(ME)压力、顺应性、耳道容积和鼓室图宽度。虽然 WNL 的范围是基于人群的平均值,但往往没有考虑到个体差异,从而可能导致误诊。由不对称的 ME 压力引起的 AV 等疾病,即使鼓室测压结果在正常范围内,也会出现症状。社论建议采用更全面的诊断方法,包括详细的患者病史、动态测试方法以及额外的听力和平衡测试,以提高诊断的准确性和患者的治疗效果。鼓室测量数据的对称性至关重要,由于存在潜在危害,应避免使用瓦尔萨尔瓦手法。未来的研究应致力于改进诊断标准和开发个性化方法,以更好地理解和管理 ME 问题。
Reevaluating the notion of “within normal limits” in tympanometry: implications for alternobaric vertigo and more
This editorial explores the notion of "within normal limits" (WNL) in tympanometry, focusing on its limitations in identifying conditions such as alternobaric vertigo (AV) and ground-level alternobaric vertigo (GLAV). Tympanometry is a simple diagnostic instrument that measures middle ear (ME) pressure, compliance, ear canal volume, and the width of tympanogram. While WNL ranges are based on average values from the population, they often do not account for individual differences, leading to possible misdiagnoses. Conditions such as AV, caused by asymmetric ME pressure, can show symptoms even when tympanometry results are within normal ranges. The editorial suggests a more thorough diagnostic approach that includes detailed patient histories, dynamic testing methodologies, and additional hearing and balance tests to improve diagnostic accuracy and patient outcomes. Symmetry in tympanometry data is crucial, and the Valsalva maneuver should be avoided due to potential harm. Future research should aim to improve diagnostic criteria and develop personalized approaches to better understand and manage ME issues.
