Anterior Ethmoid Artery Bleeding


  • Inadvertent injury may occur during an endoscopic sinus surgery.
  • Control of epistaxis


  • AEA runs along ethmoid roof in anteromedial direction
  • Direction of arterial flow is from lateral to medial

Keep in Mind/Things to Remember:

  • Bleeding may be controlled with suction monopolar cautery, which needs to be used judiciously on a low setting. Alternatively a bipolar cautery can be used to minimize current dispersion.
