Anterior Ethmoid Artery Bleeding

Indications:

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

Highlights:

• 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.
