With the advent of shoulder magnetic resonance imaging (MRI), ganglion cysts adjacent to the superior labrum have been increasinglyrecognized.1-3The spinoglenoid notch cyst (SGNC) which causes suprascapular nerve compression has been well documented,3-16 and the association of superior labral anterior-posterior (SLAP) lesions with spinoglenoid cysts has gained more attention.2.5-16 Mostly, the SGNC is approached through7 the labral tear within the glenohumeral joint. Because this approach can not provide enough space to operate, normally the SGNC can only be decompressed. So we try to find approaches to expose and excise the SGNC exactly.
