Abstract: Background: Recently, the existence of sensory branches of the suprascapular nerve (SSN) has been reported, and sensory disturbance at the lateral and posterior aspect of the shoulder has been focused on as a symptom of SSN palsy. We have performed arthroscopic release of SSN at the suprascapular notch in patients with the sensory disturbance since 2006. The purposes of this study were to introduce the arthroscopic surgical technique and to investigate postoperative recovery of sensory disturbance. Methods: Twenty-five shoulders (11 men and 14 women, average age: 63.9 years (range, 41-77)) followed for more than 1 year were included in this study. Arthroscopic decompression of SSN was performed using a suprascapular nerve portal (SN portal) as a landmark for approaching the suprascapular notch. Sensory disturbance of the shoulder was evaluated pre- and postoperatively. The follow-up period was 12-30 months (avg. 18.5). Results: The arthroscopic procedures was able to be performed safely. The preoperative sensory disturbance fully recovered postoperatively in all shoulders. Conclusion: Arthroscopic release of SSN is considered to be a useful procedure for the entrapment of SSN at the suprascapular notch. The sensory disturbance at the lateral and posterior aspect of the shoulder can be used as one of the criteria of diagnosing SSN palsy especially in shoulders with massive rotator cuff tear, which usually have difficulty in diagnosing and assessing the treatment results of associated SSN palsy.
