Neuropraxia of the greater auricular nerve is an uncommon complication of shoulder surgery, with the patient in the beach chair position. The greater auricular nerve, a superficial branch of the cervical plexus, is vulnerable to neuropraxia due to its superficial anatomical location. In this case series, we present three cases of neuropraxia associated with direct compression by a horseshoe headrest, used in routine positioning for uncomplicated shoulder surgery. We outline the risk of using devices of this nature and discourage the use of similar headrest devices due to the potential complications in headrest devices that exert pressure on the posterior auricular area to maintain head position during surgery.
耳大神经失用是肩部手术一种不常见的并发症，患者处于沙滩椅位时易发生。耳大神经是颈丛的一个浅表分支，因其浅表的解剖位置而容易发生失用。在本病例系列中，我们呈现了3例与马蹄形头枕直接压迫相关的耳大神经失用病例，该头枕用于简单肩部手术的常规体位摆放。我们概述了使用此类装置的风险，并不鼓励使用类似的头枕装置，因为这类头枕装置在手术过程中向后耳区域施加压力以维持头部位置时可能会引发并发症。
