Introduction/Objective: Anterior canalithiasis is an uncommon and challenging diagnosis. This is due in part to the difficulty of defining the affected side, the extreme positioning required to carry out described therapeutic maneuvers, and the infrequent use of specific maneuvers. Our objective is to present a new treatment alternative for anterior canalithiasis which is based on the well-known canalith repositioning procedure (CRP) described by Epley and which is used routinely in the treatment of both posterior and anterior canalithiasis. Analysis of the standard CRP for anterior canalithiasis with a biomechanical model validates that this new maneuver is an enhanced treatment option for anterior canalithiasis. We call the new maneuver the "short CRP." Methods: A previously published 3D biomechanical model of the human labyrinths for the study of BPPV was used to analyze the conventional CRP in the treatment of anterior canalithiasis. The expected position of free otoliths near the anterior ampulla of the anterior semicircular duct was followed while recreating the sequential positions of the CRP. Although the standard CRP was possibly effective, certain enhancements were evident that could increase successful repositioning. These enhancements were incorporated into the modification of the CRP presented here as the "short CRP" for anterior canalithiasis. Results: The traditional CRP used for posterior canalithiasis can also be used for anterior canalithiasis. Although in the traditional CRP the head hangs 30° below horizontal, our simulation shows that a 40° head-hang below horizontal is an enhancement and may ensure progression of anterior otolith debris. Elimination of Position 4 of the classic CRP, in which the face is turned 45° toward the floor, was also seen as an enhancement as this position is predicted to cause retrograde movement of otoliths back into the anterior canal if the patient tucks the chin in position 4 or when sitting up. Conclusion: A modification of the CRP called the "short CRP" can be used to treat anterior canalithiasis. Model analysis predicts possible increased efficacy over the standard CRP. Model analysis of existing BPPV treatments is a valuable exercise for examination and can lead to realistic enhancements in patient care.

早期Canalithiasis的短CRP:一种基于生物力学模型仿真的新方法。

引言/目的:前部小腿不安症是一种罕见且具有挑战性的诊断。这部分是由于难以确定患侧,进行所述治疗操作所需的极端定位以及特定操作的不频繁使用。我们的目标是根据Epley所描述的众所周知的Canalith重新定位程序(CRP),提出一种新的前小弯管治疗方法,该方法通常用于治疗后小弯管和前小弯管治疗。用生物力学模型对前部小白痴病的标准CRP进行分析,验证了这一新方法是对前部小白痴病的增强治疗选择。我们称这种新策略为“短CRP”。方法:使用先前发布的用于迷宫迷走神经研究的3D生物迷宫生物力学模型来分析常规CRP在治疗前小便致残症中的作用。在重建CRP的顺序位置时,遵循游离的耳石的预期位置,靠近前半圆形导管的前壶腹。尽管标准的CRP可能有效,但是某些增强功能显然可以增加成功的重新定位。这些增强功能被合并到CRP的修改中,此处被称为“前CRT”的“短CRP”。结果:传统的CRP用于后方白内障,也可以用于前部白内障。尽管在传统的CRP中,头悬挂在水平面以下30°,我们的模拟显示,水平以下40°的头顶悬挂会增强效果,并且可以确保前耳石碎片的进展。消除了经典CRP的位置4,在这种情况下,面部朝着地板旋转了45°,这也被认为是一种增强,因为如果患者将下巴tu到下巴,预计该位置会导致耳石逆行运动回到前管。位置4或坐起来时。结论:一种称为“短CRP”的CRP修饰可用于治疗前小便致残症。模型分析预测,与标准CRP相比,疗效可能会提高。现有BPPV疗法的模型分析是进行检查的有价值的练习,可以切实提高患者护理水平。消除了经典CRP的位置4,在这种情况下,面部朝着地板旋转了45°,这也被认为是一种增强,因为如果患者将下巴tu到下巴,预计该位置会导致耳石逆行运动回到前管。位置4或坐起来时。结论:一种称为“短CRP”的CRP修饰可用于治疗前小便致残症。模型分析预测,与标准CRP相比,疗效可能会提高。现有BPPV疗法的模型分析是进行检查的有价值的练习,可以切实提高患者护理水平。消除了经典CRP的位置4,在这种情况下,面部朝着地板旋转了45°,这也被认为是一种增强,因为如果患者将下巴tu到下巴,预计该位置会导致耳石逆行运动回到前管。位置4或坐起来时。结论:一种称为“短CRP”的CRP修饰可用于治疗前小便致残症。模型分析预测,与标准CRP相比,疗效可能会提高。现有BPPV疗法的模型分析是进行检查的有价值的练习,可以切实提高患者护理水平。如果患者将下巴tu缩在位置4或坐下时,预计该位置还会引起耳石逆行运动回到前管内,这也被认为是一种增强。结论:一种称为“短CRP”的CRP修饰可用于治疗前小便致残症。模型分析预测,与标准CRP相比,疗效可能会提高。现有BPPV疗法的模型分析是进行检查的有价值的练习,可以切实提高患者护理水平。如果患者将下巴tu缩在位置4或坐下时,预计该位置还会引起耳石逆行运动回到前管内,这也被认为是一种增强。结论:一种称为“短CRP”的CRP修饰可用于治疗前小便致残症。模型分析预测,与标准CRP相比,疗效可能会提高。现有BPPV疗法的模型分析是进行检查的有价值的练习,可以切实提高患者护理水平。
