Objective: Ethmoidal dural arteriovenous fistulas (eDAVF) are usually approached via a pterional or a (bi-)frontal craniotomy. A more direct route to the fistula is possible through a trans-frontal sinus approach.

Method: The trans-frontal sinus approach is described and illustrated by video, in a case of an ethmoidal arterio-venous fistula.

Results: The fistula could be reached without any need for brain and olfactory tract retraction. The patient had no postoperative neurological deficits. Postoperative angiography confirmed the cure of the fistula.

Conclusions: The trans-frontal sinus approach is the most direct approach when treating an eDAVF surgically, allowing the preservation of neural structures with minimal to no brain manipulation. It is highly worth considering, especially in cases of large frontal sinuses.
