Abstract
Regional techniques in parotid surgeries include superficial cervical plexus block (SCPB) and auriculotemporal nerve (ATN) block, which can be used as an anesthetic technique for awake parotidectomy. To evaluate the efficacy of cervical RLB as an alternative to SCPB both combined with ATN block in parotid surgery. A total of 40 patients undergoing parotid surgery were prospectively randomized into either SCPB group (n=20) or cervical RLB group (n=20) with 20 ml of 0.25% bupivacaine plus 5mcg\ml epinephrine both were combined with ATN block using 5mL of 0.25% bupivacaine plus 5mcg\ml epinephrine. The results were the time to first request of analgesia was longer in group RLB than group SCPB. Total intra operative fentanyl consumption and post-operative pethidine consumption in the first 24h were lower in group RLB. All patients (100%) in SCPB required rescue of pethidine, while only 40% of patients required pethidine in RLB. VAS was lower in group RLB from 2 to 24-hour post-operatively, but it was associated with more hypotension and longer technique time occurred in RLB than SCPB. No significant difference as regard side effects except for 20% Horner’s syndrome in group SCPB. Cervical RLB showed longer time to 1st analgesic request, lower intraoperative anesthetic consumption, lower total post-operative pethidine consumption and lower VAS but with longer time of technique performance in RLB group and more hypotension than SCPB group. Incidence of 20% Horner’s syndrome in SCPB group.
