Nasal/sinus endoscopy, surgical with ethmoidectomy; partial (anterior)

AI EXPLANATION: Endoscopic partial ethmoid sinus surgery is an outpatient procedure that removes inflamed tissue and noncancerous growths, known as nasal polyps, from the sinuses. A physician guides a narrow, lighted instrument with a tiny camera through the nostrils to access the sinuses between the eyes and the bridge of the nose. Working through the nasal passages without external incisions, the doctor opens the blocked sinus passages and removes polyps to restore normal airflow and drainage.
