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.
Study Design:
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.
Conclusion:
Indwelling maxillary nerve catheter methods decrease anesthetic consumption and provide good postoperative analgesia.
