Nasal polyp surgery is the removal of a growth inside the nose or the sinuses through incision. It is usually employed by a medical professional when other treatment methods fail to relieve a person of nasal congestion, loss of sense of smell, or sinus infection caused by nasal polyps. It is normally done as an outpatient procedure that allows a patient to be home within the day. There are two ways to perform nasal polyp surgery — nasal polypectomy and functional endoscopic sinus surgery (FESS). A person who has a bleeding disorder, coronary disease, or asthma that is poorly managed is generally considered ineligible to undergo nasal polyp surgery.

One type of nasal polyp surgery, nasal polypectomy, is typically performed under local anesthesia. It is commonly chosen as a surgical option to remove a small nasal polyp that can be easily seen and reached through the nostrils. During the procedure, the nose is held open by a nasal speculum to facilitate removal of the polyp with forceps or a wire loop. A suction device or microdebrider may also be used to extricate the polyp. Packing and pressure or electro-cauterization is usually employed to control bleeding during the procedure.

FESS is a minimally invasive surgical technique employed to remove a nasal polyp that is not easily visible or is located on the roof of the nose or on the sinuses. The procedure may be done under local or general anesthesia. It is done with the aid of an endoscope — an instrument with a tiny camera attached to a thin tube and used to give the surgeon a better view of the polyp and the area surrounding it. The surgeon, usually an otolaryngologist, removes the nasal polyp using tiny instruments and guided by the endoscope.

Prior to surgery, a patient is usually required to undergo certain tests. These tests may include, among others, nasal and sinus endoscopies and computerized tomography (CT) scan of the sinuses. Additional tests may also be advised for a patient suffering from a medical condition or disease that precludes nasal polyp surgery as a treatment option.

To avoid false expectation, it is advisable that a patient who will undergo nasal polyp surgery be made aware that his or her sense of smell may not be restored. The growth of nasal polyp may also recur. As such, it may be necessary to continue with treatment after surgery to prevent the recurrence of nasal polyps and their symptoms.
