Abstract
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-formalinized cadaver heads were examined. Dissection was performed by a precaruncular 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 precaruncular approach.
DISCUSSION/CONCLUSION: The precaruncular 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 i.e. Horner's muscle and the nasion. This article is protected by copyright.
