The procedure described by CPT® Code 61440 refers to a craniotomy specifically performed for the sectioning of the tentorium cerebelli, which is classified as a separate procedure. The tentorium cerebelli is a significant dural fold that acts as a protective barrier over the cerebellum and separates it from the occipital lobes of the brain. This procedure is typically indicated in cases where there is a need to address conditions such as arteriovenous malformations located in the dura mater at the apex of the tentorium or to relieve life-threatening intracranial pressure that may result in brain herniation. The craniotomy involves making a substantial incision at the base of the head, followed by careful dissection and retraction of the muscles to access the skull. A craniotome or Gigli saw is utilized to create a wide opening in the occipital region, ensuring that surrounding structures, particularly the sinuses, are not damaged. The dura mater is then meticulously opened to expose the tentorium cerebelli, allowing for the necessary surgical interventions to be performed. This procedure is critical in managing severe neurological conditions and requires a high level of precision to minimize risks and ensure patient safety.

The craniotomy for section of the tentorium cerebelli is indicated for specific medical conditions that necessitate surgical intervention. These include:
The procedure for a craniotomy for section of the tentorium cerebelli involves several critical steps:
Post-procedure care following a craniotomy for section of the tentorium cerebelli involves monitoring the patient for any signs of complications, such as infection or excessive bleeding. Patients may require intensive care to manage intracranial pressure and neurological status. Recovery may involve pain management and rehabilitation to address any deficits resulting from the procedure. Follow-up imaging may be necessary to assess the success of the intervention and ensure that there are no further complications.
