Through the use of conventional microscopy or exoscopy for large lobulated nerve sheath tumors, the posterior root attachment is often visualized only after mobilizing the tumor. Here, the authors describe the utility of angled endoscopy with its panoramic view for a T10 nerve sheath tumor. Gross-total extracapsular excision was achieved utilizing a minimally invasive right paraspinous approach, fenestration, lateral durotomy, sliding delivery of the tumor, sharp dissection of radicular attachments under neuromonitoring, and dural closure with oblique clips. Angled endoscopes help visualize the attachments behind large multilobulated tumors and confirm the totality of excision.

When conservative treatment fails, surgical repair is indicated. Especially ventral leaks necessitate invasive approaches with substantial blood loss and tissue trauma. Full endoscopic spine surgery (FESS) enables circumferential access via the transforaminal approach. Here, the authors show the successful repair of a ventral CSF leak in the thoracic spine after removal of bony osteophytes utilizing FESS with placement of a dural substitute and sealant. Lasting symptom relief was reported. These results suggest that FESS is safe and efficient for the repair of spontaneous and incidental CSF leaks.

Significantly expanding the scope of Destandau’s system within MISS, it serves as a pivotal link to unilateral biportal endoscopy (UBE) for endofusion. The method involves minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) using a 4-mm rigid endoscope through Destandau’s system. With the widespread familiarity with Destandau’s system and the absence of specialized instrument requirements, this approach is easily adoptable, particularly in resource-limited centers. The favorable clinical and radiological outcomes underscore the effectiveness of this technique, propelling the role of endoscopy in MISS, particularly in endofusion.

The authors report the technique during surgery for L5–S1 herniated disc. Ultrasound provided real-time visualization of the pathology and neural elements.

The patient tolerated the procedure well, with resolution of preoperative pain and strength improvement. Postoperative MRI revealed a residual asymptomatic disc fragment that was retrospectively identified on ultrasonography. Minimally invasive ultrasound could become a useful supplement to direct visual and tactile assessment during tubular microdiscectomy, but further experience with surgical anatomy on ultrasound is required.
