Endoscopic Approach to Isolated Mucocele of the Posterior Ethmoid, Challenge, and Technique Description

Abstract

Isolated mucocele of the posterior ethmoid cells is a relatively rare pathological condition, so the technical features of its surgical treatment have not been clearly de!ned. Traditional approaches to this region include opening all ethmoid cells and using general anesthesia as patient support. However, in patients with limitations regarding anesthesia, it may pose problems. The present paper discusses a clinical case of a posterior ethmoid cell mucocele that was drained by direct access medially from the middle turbinate, similar to access to the sphenoethmoidal recess. In addition, given the small amount of damage, it was decided to perform the operation under combined anesthesia, and image guidance was used for the speed and accuracy of the surgical approach. A direct endoscopic approach for isolated posterior ethmoid cell pathology can serve as an alternative to standard access. If it is necessary to open only the posterior ethmoid cell in patients with high risks of general anesthesia, an endoscopic approach through the middle turbinate can be used.
