Endoscopic sinus surgery, also known as functional endoscopic sinus surgery (FESS) can provide relief for patients suffering from chronic sinus and nasal conditions. Houston-area Sinus Surgeon Dr. Shawn Allen is a Board-Certified Otolaryngologist (ENT) and fellowship-trained rhinologist with extensive experience in endoscopic sinus surgery.
There are a variety of sinus and nasal conditions that can be successfully treated with endoscopic sinus surgery, including:
In most cases, Dr. Allen will suggest non-surgical medical treatment options before recommending endoscopic sinus surgery unless these have already been attempted without success.
Endoscopic sinus surgery is designed to remove blockages from the nasal passages and clear sinus pathways and airways in order to restore optimal sinus drainage and nasal breathing functions. Surgery is visualized using an endoscope, which is a narrow rod with lenses that allow excellent visualization within the nose using an attached camera and video tower setup. Special endoscopic surgical tools are used to remove thin walls that separate the sinuses from the nasal cavities while preserving the functional lining within the sinuses and ensuring adequate room for drainage and the delivery of topical medications via nasal irrigations. Polyps and severely inflamed tissues are also removed to the extent necessary to improve sinus function. This endoscopic approach leaves no visible incisions, scars, or changes in appearance.
The first step is a consultation with Dr. Allen. He will perform an examination, review your medical history and CT findings, and discuss your concerns before reviewing treatment options with you. If endoscopic sinus surgery is recommended, he will provide detailed instructions to follow leading up to and after surgery.
Endoscopic sinus surgery is an outpatient procedure performed under general anesthesia. Dr. Allen will meet with you prior to your surgery and answer any last minute questions you may have. Surgery generally takes about 2 to 3 hours but that can vary based on the complexity of your condition. Once Dr. Allen has completed surgery he will place dissolvable packing that will aid in healing while reducing initial crusting in the nose, as well as steroid-eluting stents when appropriate. These do not significantly impact nasal breathing, which generally improves within a few days as swelling resolves.
Your recovery time can vary, but patients typically take one week off of work and other activities. Patients may notice they feel most fatigued or uncomfortable 2 to 3 days after surgery—this is normal as initial healing involves the onset of swelling and inflammation within the nose. This improves in most cases by 4 to 5 days after surgery, particularly when adhering to the post-op instructions and using nasal saline rinses appropriately. Nosebleeds are generally mild and may be more frequent for 2 or 3 days after surgery, and activity restrictions are in place for 2 weeks following sinus surgery to prevent excessive bleeding.
The best way to determine if endoscopic sinus surgery is right for you is to have a consultation with an experienced Rhinologist. If medications and other treatments have failed to resolve your sinus symptoms, surgery may be the best treatment option for you. Surgery has proven superior to ongoing medical treatment and provides lasting improvement in quality of life when impacted significantly by sinusitis.
