Why is endoscopic sinus surgery called functional?
The reasoning and concepts supporting the use of FESS have recently become widely accepted. (The term “functional” was introduced to distinguish this type of endoscopic surgery from nonendoscopic, “conventional” procedures. 3,4) The goal of FESS is to return the mucociliary drainage of the sinuses to normal function.
Why is FESS functional?
The purpose of FESS in treatment of CRS is to remove any anatomical obstructions that prevent proper mucosal drainage. A standard FESS includes removal of the uncinate process, and opening of the ethmoid air cells and Haller cells as well as the maxillary ostium, if necessary.
What is septoplasty and FESS?
FESS is often combined with a septoplasty to straighten the nasal septum and allow better access to the sinuses deeper in the nose. What is the operation like? You will be admitted on the day of your surgery and will stay overnight in hospital.
What is the function of maxillary sinus?
The maxillary sinuses might simply serve to improve the respiratory function of the nose. A flow of inspiratory air does not occur. The maxillary sinuses are decisively involved in the production of nitrogen monoxide (NO) and thus in supporting the immune defense of the nasal cavity.
What are the 6 nasal sinuses?
The maxillary sinuses are located under the eyes; the frontal sinuses are above the eyes; the ethmoidal sinuses are between the eyes and the sphenoidal sinuses are behind the eyes. The sinuses are named for the facial bones in which they are located.
What is sigmoid sinus?
The sigmoid sinus is a dural venous sinus situated within the dura mater. Each sigmoid sinus begins beneath the temporal bone and follows a tortuous course to the jugular foramen, at which point the sinus becomes continuous with the internal jugular vein.
When should you consider endoscopic sinus surgery?
when should you consider endoscopic sinus surgery? Sinus surgery should be considered if medication fails to adequately relieve symptoms and the individual’s quality of life continues to suffer. The need for surgery may be due to recurrent attacks of acute Sinusitis or longer term symptoms associated with Chronic Sinusitis.
What to expect following endroscopic sinus surgery?
Bleeding: It is normal to have some bloody discharge for the first 3-5 days after sinus surgery,especially after you irrigate your sinuses.
What procedure is involved in endoscopic sinus surgery?
Endoscopic Sinus Surgery is a surgical procedure that involves the opening of the passages of the paranasal sinuses to allow for proper drainage of the nose using nasal endoscope. The paranasal sinuses are a group of four air-filled spaces that the nasal cavity. The sinuses may become infected resulting in a disease state known as sinusitis.
How is endoscopic sinus surgery performed?
The endoscope allows the surgeon to see inside the nose and sinuses, usually with a special video camera attached to the endoscope. It is performed through the nose, without face or mouth incisions. Endoscopic sinus surgery is typically done with minimal nasal packing, mild pain, and short recovery times.
