Many techniques have been proposed to improve the field of ear exploration surgery. Bipolar diathermy, packing, local vasoconstrictors, and induced hypotension are the most commonly used techniques . Diathermy can lead to local damage and delayed bleeding . Using topical vasoconstrictions can lead to hemodynamic instability especially in patients with a history of hypertension or ischemic heart disease. Induction hypotension exposes the patients to more anesthetic drugs and hence a higher risk of potential side effects. However, neither of these methods guarantees a desirable surgical field with no bleeding. Therefore, investigators are working on more effective and safer methods to reduce bleeding and hence to improve the field of surgery .
