The full form of FESS is Functional Endoscopic Sinus Surgery.
FESS, or Functional Endoscopic Sinus Surgery, is a minimally invasive surgical procedure used to treat sinus problems. It aims to improve sinus drainage and ventilation by removing any blockages or abnormalities within the nasal passages and sinuses.
Here's a breakdown:
- Functional: This indicates that the surgery focuses on restoring the natural function of the sinuses.
- Endoscopic: This refers to the use of an endoscope, a thin, flexible tube with a camera and light source, to visualize the inside of the nasal passages and sinuses during the procedure.
- Sinus: This refers to the paranasal sinuses, which are air-filled cavities located around the nasal cavity.
- Surgery: This signifies that a surgical procedure is performed to correct the underlying sinus problem.
