Is this trial a fit for you?
✓Likely a good fit
Adults over 18 with ASA physical status I–II scheduled for elective canal-wall-down mastoidectomy or similar middle ear surgery who can attend the participating Istanbul site are ideal candidates.
✕Probably not a fit
Patients on anticoagulants, with infection at the block site, allergies to the planned drugs, ASA IV–V, or those who refuse or cannot cooperate are excluded and unlikely to benefit from this intervention.

What this trial studies
Middle ear surgery is common in ENT and can provoke sympathetic responses that raise blood pressure and heart rate, increasing the risk of hemorrhage and impairing the surgical field. This interventional trial applies an ultrasound-guided auricularis magnus nerve block perioperatively and compares outcomes to a control group. The protocol uses a small, targeted local anesthetic injection under ultrasound visualization to improve analgesia and limit side effects. Primary outcomes include postoperative pain scores and intraoperative hemodynamic/bleeding measures in adults undergoing elective canal-wall-down mastoidectomy or related procedures.
Why it matters
Potential benefit: If successful, the nerve block could lower postoperative pain, reduce intraoperative bleeding, improve surgical field quality, and decrease opioid needs after middle ear surgery.
How similar studies have gone: Ultrasound-guided peripheral nerve blocks have shown benefit for perioperative analgesia in other procedures, but use of the auricularis magnus block specifically for middle ear surgery is relatively novel and not yet well-established.
