AbstractSafe and effective cranial analgesia can be achieved by blocking the sensitive nerves of that region. These include the supraorbital nerve, the supratrochlear nerve, the zygomaticotemporal nerve, the auriculotemporal nerve and the greater and lesser occipital nerves which are accessible at typical and most proximal points. Preferably long acting local anesthetics such as ropivacaine 0.75% or levobupivacaine 0.5% are used supplemented with 5 microg/ml epinephrine to reduce systemic resorption and to elongate the duration. Scalp blocks are useful for intraoperative neurologic testing of the patient during awake craniotomy or for supplementation of general anesthesia for other forms of craniotomy. Other applications are minimally invasive and stereotactic neurosurgery including deep brain stimulation, photodynamic therapy of actinic ceratosis, cranial plastic surgery and pain therapy.
