title: A new method of continuous maxillary nerve block with an indwelling catheter.
abstract: OBJECTIVE
  We describe continuous maxillary nerve block at the pterygopalatine fossa and investigate the efficacy of this technique for perioperative pain control in oral surgery.
  
  
  METHODS
  Sixteen patients undergoing radical maxillary sinusotomy were enrolled; group I (n = 8) received general anesthesia without maxillary nerve block, and group II (n = 8) received maxillary nerve block before general anesthesia. The intraoperative concentration of sevoflurane, the extent of blockade, and total analgesics (diclofenac sodium) needed after surgery were recorded.
  
  
  RESULTS
  The mean sevoflurane concentration was significantly lower in group II. Diclofenac sodium consumption was significantly reduced in group II.
  
  
  CONCLUSIONS
  Indwelling maxillary nerve catheter methods decrease anesthetic consumption and provide good postoperative analgesia.
