Shoulder arthroscopy is a common treatment for numerous different pathologies. An iatrogenic nerve injury that occurs during shoulder arthroscopy is more common than previously recognized. However, though many nerve pathologies are increasingly being recognized, reported cases of greater auricular nerve injury are limited. For instance, a case of greater auricular nerve palsy was reported in only 2 series that used a horseshoe headrest. One set of authors discontinued and recommended against use of this headrest, and the other recommended a headrest redesign. Here we report on a case of greater auricular nerve palsy that occurred after the patient's anterior-inferior and posterior-inferior labral tear was arthroscopically repaired using beach-chair positioning and a standard universal headrest. The palsy resulted in numbness and dysesthesia, which lessened gradually over 3 months after surgery and was completely resolved by 6 months.
肩关节镜检查是治疗多种不同病症的常用方法。肩关节镜检查过程中发生的医源性神经损伤比之前认为的更为常见。然而，尽管越来越多的神经病变被发现，但关于耳大神经损伤的报道病例却很有限。例如，仅有2个使用马蹄形头枕的系列报道了耳大神经麻痹的病例。一组作者停止使用并建议不要使用这种头枕，另一组则建议对头枕进行重新设计。在此，我们报告一例耳大神经麻痹病例，该病例发生在患者采用沙滩椅位和标准通用头枕进行关节镜下修复前下和后下盂唇撕裂之后。该麻痹导致了麻木和感觉异常，术后3个月逐渐减轻，6个月时完全恢复。
