Intervertebral disc degeneration is a significant contributor to back pain and a leading cause of disability worldwide. Numerous animal models of intervertebral disc degeneration exist. We demonstrate an ovine model of intervertebral disc degeneration, utilizing a drill bit, which achieves a consistent disc injury and reproducible level of disc degeneration.

Here, we present a protocol to resect benign infratemporal fossa tumors via an endoscopic-assisted transoral lateral molar approach with low-temperature plasma ablation and intraoperative mandibular nerve monitoring. This minimally invasive technique prioritizes anatomical preservation, functional recovery, and avoidance of external scarring, demonstrating feasibility for well-demarcated lesions ≤4 cm in diameter.

FAQs
Patient positioning places the patient laterally and helps align the flank with the operative corridor. The surgeon then develops a route through the abdominal wall and retroperitoneal tissues while recognizing the peritoneum, psoas muscle, nerves, vessels, and other nearby structures. This sequence is important because safe progress depends on distinguishing the intended pathway from anatomy that requires protection.
Protecting the peritoneum helps preserve the separation between the retroperitoneal working corridor and the abdominal cavity. This supports the approach’s goal of limiting entry into the peritoneal space and may reduce disruption of abdominal organs compared with transperitoneal access. The distinction matters when selecting a route for procedures involving structures located behind the peritoneal cavity.
The peritoneum, psoas muscle, nerves, vessels, and other nearby anatomy are central technical concerns. Their location along or near the developing corridor means that surgeons need detailed anatomical knowledge while advancing through the retroperitoneal tissues. Careful identification and protection of these structures are essential for managing risks that are specific to this surgical route.
The procedure begins with lateral positioning, followed by development of a corridor through the abdominal wall and retroperitoneal tissues. During this dissection, the surgeon identifies the peritoneum, psoas muscle, nerves, vessels, and other relevant anatomy. The intended target is then approached through the established route while nearby structures remain protected throughout the operation.
This route may be selected for procedures involving the lumbar spine, kidneys, adrenal glands, or major vessels. Its usefulness comes from providing access to these posterior or retroperitoneal structures while limiting disruption of the abdominal cavity. The choice still depends on the target anatomy, the required corridor, and the surgeon’s ability to manage approach-specific anatomical risks.
Compared with transperitoneal access, the lateral retroperitoneal approach may reduce disruption of abdominal organs because it limits entry into the abdominal cavity. That potential benefit does not remove the need for careful planning. Surgeons must weigh the desired access against the anatomy encountered along the flank and the risks associated with the peritoneum, psoas, nerves, and vessels.
