FESS stands for Functional Endoscopic Sinus Surgery. It's a surgical procedure performed to treat chronic sinusitis and other sinus-related problems. Unlike traditional sinus surgery, which involves making external incisions, FESS is minimally invasive and is performed entirely through the nostrils using an endoscope—a thin, flexible tube with a camera and light at its tip.
During FESS, the surgeon uses specialized instruments to remove blockages, polyps, or diseased tissue from the sinuses, allowing for better drainage and airflow. The procedure aims to improve the function of the sinuses while preserving the natural anatomy of the nasal passages.
FESS is often considered when conservative treatments like medications and nasal sprays fail to provide relief from chronic sinus symptoms. It can help alleviate symptoms such as facial pain, pressure, congestion, and recurrent sinus infections. Recovery from FESS is typically quicker than traditional sinus surgery, with many patients able to return to normal activities within a few days to a week, although full recovery may take several weeks. As with any surgical procedure, there are potential risks and complications, so it's essential to discuss the procedure thoroughly with a qualified healthcare provider.
