ETHMOIDAL ANATOMIC VARIATIONS. CLINICORADIOLOGICAL STUDY
Although the ethmoid is the most addressed bone in nasal endoscopic procedures, few studies have been conducted documenting its anatomic variations. Most of the time, surgeons perform a large anterior ethmoidectomy, a procedure so extensive that does nor allow a detail view of it’s anatomy. Using minimally invasive surgical techniques and image guided surgery we have found anatomic variations of the ethmoid sinus that if proven to have a functional implicationnon in the nasal phisiology, it may change the actual rationale for functional endoscopic sinus surgery of the ethmoid .
