The Kernig incision is a surgical approach used in neurosurgery to access the posterior fossa of the brain, particularly for procedures involving the cerebellum, brainstem, and fourth ventricle. This incision is made in the midline of the posterior neck, extending from the external occipital protuberance down to the upper cervical spine. It provides excellent exposure to structures in the posterior cranial fossa while minimizing muscle damage. The Kernig incision is commonly used for procedures such as removal of posterior fossa tumors, treatment of Chiari malformations, decompression of the brainstem, and management of certain types of hydrocephalus. After making the skin incision, the surgeon dissects through the nuchal ligament and muscles to expose the occipital bone and upper cervical vertebrae. A craniotomy or craniectomy is then performed to access the intracranial structures. This approach is preferred when extensive exposure of the posterior fossa is required, though it may result in postoperative neck pain and stiffness due to muscle dissection. The procedure typically requires general anesthesia and patients are positioned prone or in a modified sitting position to optimize surgical access and reduce bleeding, as seen in various neurosurgical procedures 1. Some key points to consider when using the Kernig incision include:
- The incision should be made carefully to avoid damaging surrounding tissues and structures
- The surgeon should be experienced in using this approach to minimize complications
- The patient should be closely monitored during and after the procedure to ensure optimal outcomes
- The Kernig incision is just one of many surgical approaches used in neurosurgery, and the choice of approach will depend on the specific needs of the patient and the procedure being performed, as discussed in recent studies 1. It's worth noting that while the provided evidence does not directly discuss the Kernig incision, it does provide information on various neurosurgical procedures and approaches, highlighting the importance of careful planning and execution in these procedures 2, 3, 4, 5.
