Nasal/sinus endoscopy, surgical, with frontal sinus exploration

AI EXPLANATION: Endoscopic sinus surgery with frontal sinus exploration is an outpatient procedure that evaluates and clears blockages in the frontal sinuses located behind the forehead and above the eyebrows. A specialist inserts an endoscope—a thin, lighted instrument equipped with a tiny camera—into the nose to carefully examine the passages, remove obstructing tissue, bone, or polyps, and restore natural sinus ventilation and fluid drainage without needing facial incisions.
