Ganglion cysts causing suprascapular nerve compression are an uncommon cause of suprascapular nerve compression. The advent of magnetic resonance imaging (MRI) and its application in patients with shoulder pain has improved the ability to diagnose cystic lesions causing extrinsic compression of the suprascapular nerve. Traditionally, treatment of suprascapular nerve compression by a ganglion cyst has required open cyst excision through either a deltoid and infraspinatus muscle takedown or a muscle splitting approach. We present three cases of suprascapular nerve compression by a ganglion cyst in which the cyst was decompressed arthroscopically. In each case the patient's symptoms resolved after arthroscopic cyst decompression, and a postoperative MRI does not demonstrate reaccumulation of the cyst fluid. Arthroscopic ganglion cyst decompression is a well-tolerated approach to this problem that avoids the morbidity of an open surgical procedure. The absence of recurrent cyst formation combined with resolution of the symptoms attests to the success of this method.
腱鞘囊肿导致肩胛上神经受压是肩胛上神经受压的一种罕见原因。磁共振成像（MRI）的出现及其在肩痛患者中的应用提高了诊断导致肩胛上神经外部受压的囊性病变的能力。传统上，腱鞘囊肿导致的肩胛上神经受压的治疗需要通过三角肌和冈下肌切开或肌肉劈开入路进行开放性囊肿切除。我们报告3例腱鞘囊肿导致肩胛上神经受压的病例，这些囊肿通过关节镜进行了减压。在每例病例中，关节镜下囊肿减压后患者症状均得到缓解，术后MRI未显示囊肿液再次积聚。关节镜下腱鞘囊肿减压是一种对该问题耐受性良好的方法，避免了开放性手术的并发症。囊肿未复发且症状得到缓解证明了该方法的成功。
