	<ol>
		<li>Drill the inferior edge of the cranial lamina,&#160;proceeding&#160;laterally-to-medially and&#160;extending&#160;cranially while undercutting the base of the spinous process.</li>
		<li>Protect the dura safely by staying external to the ligamentum flavum until bone removal is complete. Avoid drilling centrally without orientation.&#160;</li>
	</ol>
	</li>

	<li>Perform contralateral drilling.&#160;
	<ol>
		<li>On the contralateral side,&#160;drill and thin the superior medial edge of the caudal lamina until the ligamentum flavum is exposed along the laminar margins.</li>
		<li>Perform continuous irrigation to clear out bone dust, improve visualization, and minimize thermal injury.&#160;</li>
	</ol>
	</li>
	<li>Detach the contralateral flavum.&#160;
	<ol>
		<li>Using a Kerrison rongeur,&#160;identify&#160;the insertion points of the ligamentum&#160;flavum&#160;and detach it from the caudal bony edges.</li>
		<li>Work carefully to separate the ligament from&#160;the bone&#160;without traction on the dura.&#160;</li>
	</ol>
	</li>
	<li>Perform ipsilateral drilling.&#160;
	<ol>
		<li>Perform&#160;additional&#160;drilling on the ipsilateral lamina as needed to enlarge the working space and ensure complete ligamentum flavum&#160;detachments.&#160;</li>
	</ol>
	</li>

		<li>Rotate the cannula to visualize all angles of the disc space. Identify and remove any residual herniated material with forceps to ensure complete decompression.&#160;</li>
	</ol>
	</li>
	<li>Confirm adequate decompression.
	<ol>
		<li>Confirm adequate decompression by ensuring relaxation and free movement of the nerve root, together with pulsation of the dural sac. This signals the endpoint of the procedure.</li>

Lumbar disc herniation accounts for 5% of lower back disorders and remains one of the most common indications for spine surgery7. In patients with radicular pain and no severe neurological deficits, conservative management is advised for 4&#8211;6 weeks. For patients with progressive or persistent symptoms despite conservative non-operative therapy, microdiscectomy is indicated. Microdiscectomy is traditionally performed via an open approach, but can now be done via a tubular or endoscopic approac...

Endoscopic disc surgery was founded in the 1970s and represents a trend toward minimally invasive surgical approaches1. Neurosurgery has been at the forefront of technological advancement, with each generation introducing new tools that improve surgical accuracy, efficiency, and clinical outcomes2. The combination of endoscopic visualization with external monitors has expanded the adoption of this surgical approach from lumbar to thoracic and cervical pathologies3.
Endoscopic spine surgery continues to gain popularity due to its precision and minimally invasive approach to common spinal conditions like disc herniation. These approaches have expanded to tumor resection, infections, and segmental instability4. The technique offers several advantages, which include minimal tissue damage, decreased length of stay, and improved patient outcomes. The endoscopic approach is done through careful dissection, serial dilation, and placement of a working cannula5. Once in position, the endoscope is advanced while soft tissue is dissected until the proper trajectory and anatomical landmarks are visualized.
Research demonstrates positive outcomes for patients, with recent studies showing comparable or even superior clinical results when compared to traditional open microdiscectomy5. One limitation of endoscopic approaches cited by surgeons is the difficulty in visualizing anatomy and confirming proper location, trajectory, and depth perception6. These challenges are especially true early in training and during independent practice when there are limited anatomical landmarks or guides for decision making.
The primary objective and educational purpose of this manuscript are twofold. First, our goal is to provide a reproducible, step-by-step visual guide for endoscopic techniques used for lumbar decompression. Second, to improve procedural standardization while validating the efficacy of endoscopic spine surgery. We present three key techniques with step-by-step guidance and corresponding visual documentation. These techniques include: interlaminar microdiscectomy, interlaminar laminectomy, and transforaminal microdiscectomy. This manuscript fills important gaps in the literature by providing a clear visualization of each technique, procedural standardization with defined anatomical landmarks, and training utility for surgeons looking to refine their endoscopic approaches. Our research combines technical description with visual evidence, which we believe serves both as validation of the techniques and as a practical guide for their implementation.

uniportal endoscopic techniques for lumbar decompression: interlaminar microdiscectomy, interlaminar laminectomy, and transforaminal microdiscectomy

Uniportal Endoscopic Techniques for Lumbar Decompression: Interlaminar Microdiscectomy, Interlaminar Laminectomy, and Transforaminal Microdiscectomy

Endoscopic spine surgery enables targeted neural decompression with&#160;the least amount of tissue&#160;disruption to paraspinal structures&#160;compared to other spine surgery techniques.&#160;Though with&#160;minimal visualization, endoscopic spine surgery can be&#160;challenging.&#160;This&#160;article presents a&#160;stepwise&#160;overview of three&#160;key&#160;uniportal&#160;lumbar&#160;endoscopic techniques: interlaminar microdiscectomy, interlaminar laminectomy, and transforaminal microdiscectomy. Through integrated operative footage, the videos&#160;demonstrate&#160;indications, portal trajectory, and critical anatomic landmarks unique to each approach.&#160;
The interlaminar microdiscectomy technique is illustrated for median and paramedian disc herniations, emphasizing safe ligamentum flavum separation, dural protection, and direct fragment removal under endoscopic visualization. The interlaminar laminectomy segment details the management of central and lateral recess stenosis, highlighting stepwise bone removal, decompression of traversing and exiting roots, and controlled hemostasis within a limited corridor. The transforaminal microdiscectomy sequence&#160;demonstrates&#160;access through Kambin&#39;s triangle,&#160;foraminoplasty, and targeted fragment excision without violating the spinal canal.&#160;Operative tips focus on portal alignment, irrigation control, and avoidance of nerve injury, supplemented by discussion of ergonomic hand positioning and intraoperative troubleshooting.&#160;&#160;
Together, these video demonstrations provide a comprehensive visual reference for surgeons transitioning to endoscopic lumbar surgery. By standardizing procedural steps and emphasizing anatomical orientation, this&#160;method article aims to enhance reproducibility, expand technical&#160;proficiency, and promote the safe adoption of endoscopic decompression for lumbar disc and canal pathology.&#160;

The study includes three patients who underwent a minimally invasive, endoscopic approach to achieve lumbar decompression secondary to disc herniation. All three patients experienced relief of symptoms as documented in progress notes. Intraoperative visualization via the endoscope confirmed decompression of the thecal sac and/or nerve root.
For the interlaminar laminotomy, the interlaminar space was identified, followed by laminotomy. The ligamentum flavum was detached and subsequently removed...

Here, we present three uniportal endoscopic protocols for lumbar decompression. These techniques include interlaminar microdiscectomy, interlaminar laminectomy, and transforaminal microdiscectomy.

Endoscopic disc surgery originated in the 1970s as a minimally invasive alternative to open approaches. Advantages include minimal tissue damage, shorter hospital stays, and improved patient outcomes. Key limitations include difficulty visualizing anatomy, confirming trajectory, and gauging depth, especially in early training.This highlights the need for clear procedural guides and visual references. We present three endoscopic techniques with step-by-step visual guidance. These techniques include:interlaminar microdiscectomy, interlaminar laminectomy, and lastly, transforaminal microdiscectomy.Our manuscript provides procedural standardization, defined anatomical landmarks, and a practical training reference. Interlaminar laminectomy. Find the interlaminar space.Identify the inferior edge of the cranial lamina. This is a starting point for the procedure. Perform ipsilateral laminotomy of L4.Drill the inferior edge of the cranial lamina, proceeding laterally to medially and extending cranially while undercutting the base of the spinous process.Protect the dura safely by staying external to the ligamentum flavum until bone removal is complete. Avoid drilling centrally without orient
