A cupulolithiasis of the lateral semicircular canal is an accumulation of otolithic debris at the level of the cupula of the same canal. Its pathophysiology generally generates a specific clinical presentation. This situation can be very disabling for the patient and tricky to treat for the clinician.
The patient was a 70-year-old man with cupulolithiasis of the right lateral semicircular canal. We present here the conversion of cupulolithiasis to canalolithiasis using the Thomas Richard Vitton (TRV) repositioning chair, as well as the treatment of this canalolithiasis through a mechanical liberation maneuver.
The results of manual therapeutic maneuvers for Benign Paroxysmal Positional Vertigo (BPPV) are generally good regardless of the type of BPPV. It can sometimes be more challenging to resolve an ageotropic-type BPPV of the lateral semicircular canal and mechanically-assisted maneuvers using a repositioning chair may be required. Faced with symptom resistance despite attempts at multiple liberatory maneuvers, clinicians must be able to reconsider their initial diagnosis and investigate other potentially more serious origins of these symptoms. The TRV chair can be a treatment option in the management of cupulolithiasis, especially in cases where classic reduction maneuvers do not always yield good results.
外侧半规管耳石脱落症是指同一侧半规管壶腹嵴处的耳石碎屑堆积。其病理生理学通常会产生特定的临床表现。这种情况可能会使患者非常不适,也会给临床医生的治疗带来困难。
患者为 70 岁男性,患有右侧外半规管耳石脱落症。我们在此介绍使用托马斯·理查德·维顿(Thomas Richard Vitton,TRV)变位椅将耳石脱落症转换为管结石症,以及通过机械解脱手法治疗这种管结石症。
手动治疗手法治疗良性阵发性位置性眩晕(Benign Paroxysmal Positional Vertigo,BPPV)的效果通常很好,无论 BPPV 的类型如何。有时解决外向型外侧半规管 BPPV 会更具挑战性,可能需要使用变位椅进行机械辅助手法。面对尽管尝试了多次解脱手法但仍有症状抵抗的情况,临床医生必须能够重新考虑其初始诊断,并调查这些症状的其他潜在更严重的原因。TRV 椅可作为管理耳石脱落症的治疗选择,尤其是在经典复位手法效果不佳的情况下。
