Generally, laryngoscopic biopsy is recommended to be performed after discontinuing aspirin for one week to avoid increasing the risk of bleeding during the procedure. Laryngoscopic biopsy is an invasive procedure, during which blood vessels are likely to be damaged. Aspirin is a commonly used antiplatelet aggregation drug in clinical practice, which inhibits platelet aggregation to avoid thrombus formation. If you do not stop using aspirin, it will greatly increase the difficulty of hemostasis during the operation, but also due to the blood is not easy to coagulate and hemorrhage and other dangerous situations. Therefore, it is generally recommended to stop taking aspirin for more than a week before performing a laryngoscopic biopsy to ensure a smooth operation and to avoid complications such as postoperative bleeding. The use of aspirin before and after a laryngoscopic biopsy should be finalized in consultation with the surgeon.
