• In a study of 79 patients who underwent either percutaneous anhydrous glycerol rhizolysis (PRGR) or radiofrequency (RF) thermocoagulation, 23 (58.9%) of the 40 PRGR patients and 33 (84.6%) of the 39 RF patients experienced excellent pain relief. (medscape.com)
  • Various treatment modalities have been used to treat TN, including pharmacotherapy, stereotactic radiosurgery, suboccipital craniotomy with microvascular decompression (MVD) or partial sensory rhizotomy (PSR), and percutaneous procedures such as glycerol rhizotomy, balloon microcompression or radiofrequency rhizotomy [ 1 , 2 ].

  • Trigeminal nerve block provides hemifacial anesthesia and is used predominantly in the diagnosis and treatment of neuralgia. (medscape.com)
  • trigeminal nerve block is reserved for patients who do not respond to medical treatment or patients in whom neurologic decompression of the canal is not feasible or has failed. (medscape.com)
  • The success of a trigeminal nerve block depends on proper identification of the anatomic landmarks and the nerve itself. (medscape.com)
  • For trigeminal nerve block, the patient undergoes mild sedation. (medscape.com)
  • Before neurolysis is carried out, the patient's response to a diagnostic block with local anesthetic must be assessed. (medscape.com)
  • Percutaneous balloon compression was performed by Mullan and Lichtor in 1978 for the first time. (samobathi.com)
  • Basic monitoring must be instituted as in any major nerve block. (asra.com)
  • Local anesthetics block the initiation and conduction of nerve impulses.They are used to increase patient comfort during the procedure. (medscape.com)
  • This decreases permeability to sodium ions in neuronal membranes, resulting in the inhibition of depolarization, thereby blocking the transmission of nerve impulses. (medscape.com)
  • Meckel's cave can be percutaneously accessed to perform ablative interventions, which are regularly preceded by a positive diagnostic block. (asra.com)
