Objective In epistaxis and skull base surgery, the anterior ethmoidal artery sometimes needs to be ligated. We describe a novel, quick and scar‐free surgical technique to ligate this artery with salient landmarks allowing rapid identification. Patients and methods Twenty medial orbital walls from 10 randomly selected fresh‐frozen, non‐formalinised cadaver heads were examined. Dissection was performed by a pre‐caruncular external approach to expose the AEA in all cases. Results The Horner's muscle and nasion, two salient landmarks, have been identified for use during the pre‐caruncular approach. Discussion/Conclusion The pre‐caruncular approach is a novel combined open and endoscopic surgical approach to the anterior ethmoidal artery. It is a simple, quick and scar‐free technique. The identification of the artery is easy when using the two anatomic landmarks we describe in our study, that is Horner's muscle and the nasion.
