Summary
Background: Proper selection of anesthetic technique is important in middle ear microsurgery.
Controlled hypotension in ear surgery decreases blood loss with improved quality of the
surgical field, however, it is associated with resistance to vasodilators and delayed
recovery from anesthesia. The use of local anesthetic technique alone in middle ear surgery
decreases bleeding and reduces postoperative pain, however, pain on injection, noise, and
head-neck position had been reported with the increased risk of patient injuries.
This study aimed to compare the effects of local ear block combined with general anesthesia
versus general anesthesia alone, regarding intraoperative hemodynamics, anesthetic
consumption, recovery characteristics, postoperative pain, adverse effects and postoperative
complications.
