Delta large-channel endoscopy versus unilateral biportal endoscopy for cervicothoracic junction disc herniation: a prospective randomized controlled trial

Both surgical techniques demonstrated favorable safety profiles and clinical efficacy in the treatment of CTJDH. Compared with UBE, the Delta large-channel endoscopic approach resulted in less intraoperative blood loss and faster postoperative recovery, although it required a longer operative time. For patients with CTJDH accompanied by osteophytes or bony overgrowth, UBE provided equally satisfactory outcomes, whereas the Delta technique showed relatively poorer results in such cases. Therefore, the choice of surgical approach should be individualized based on each patient's anatomical characteristics and clinical presentation.
