Abstract
We reported a case of arthroscopic debridement of a ganglion cyst causing suprascapular nerve paralysis. A 65-year-old man complained about continuous weakness of his right arm for ten months. Following magnetic resonance imaging (MRI) that showed ganglion at right suprascapular notch, an arthroscopy revealed a juxtacapsular ganglion cyst and degenerative tear of the glenoid labrum. Arthroscopic debridement was performed. After a postoperative period of three months strength of the right arm improved without recurrence of any experienced symptoms.
