Endoscopic sinus surgery is a procedure used to treat chronic sinusitis and other conditions affecting the sinuses. The surgery involves the use of an endoscope, which is a thin, flexible tube with a light and a camera at its end. The endoscope is inserted through the nostrils to provide a clear view of the sinuses.

During the surgery, the surgeon may remove obstructions, such as polyps or nasal blockages, and enlarge the natural openings of the sinuses. This helps improve the drainage of mucus and reduces the frequency and severity of sinus infections. The use of endoscopic techniques allows for a minimally invasive approach, resulting in less pain, faster recovery, and often no external facial incisions.

Endoscopic sinus surgery is generally considered when conservative treatments, such as medications, fail to alleviate chronic sinus issues. The specific procedures performed can vary depending on the patient’s condition and the surgeon’s assessment.
