Percutaneous laminotomy/laminectomy (interlaminar approach) for decompression of neural elements, (with or without ligamentous resection, discectomy, facetectomy and/or foraminotomy), any method, under indirect image guidance (eg, fluoroscopic, CT), single or multiple levels, unilateral or bilateral; cervical or thoracic

A percutaneous laminotomy or laminectomy is a minimally invasive surgical procedure aimed at decompressing neural elements within the spine. This procedure is performed through an interlaminar approach, which involves accessing the spinal canal between the laminae of adjacent vertebrae. The primary goal is to relieve pressure on the spinal nerves or the spinal cord, which may be caused by conditions such as herniated discs, bone spurs, or other spinal abnormalities. The procedure can be performed with or without additional interventions such as ligamentous resection, discectomy, facetectomy, or foraminotomy, depending on the specific needs of the patient. Preoperative imaging studies, such as MRI, CT, or myelography, are essential for identifying the precise entry point over the spine and for planning the surgical approach. During the procedure, indirect image guidance techniques, such as fluoroscopy or CT, are utilized to ensure accurate placement of instruments and to visualize the surgical field. The use of percutaneous devices allows for a less invasive approach, reducing recovery time and minimizing tissue damage compared to traditional open surgery. Contrast material may be injected into the epidural space to enhance visualization of the surrounding structures and to assess the effectiveness of the decompression achieved. This procedure can be performed at single or multiple levels of the cervical or thoracic spine and can be unilateral or bilateral, depending on the extent of the neural compression that needs to be addressed.
