FESS usually does not cause severe postoperative sinus pain. After the procedure, it is important to keep the nose as free from crust build-up as possible. To achieve this, the surgeon may perform a lengthy cleaning two to three times per week or the...
patient may perform a simple nasal douching several times a day. Normal function usually reappears after one or two months. In patients with severe sinusitis or polyps, a short course of systemic steroids combined with antibiotics may quicken recovery.

Dental implants are artificial teeth that are anchored to bone; however if the bone is too thin, the dental implant cannot be implanted. The animation describes the bone grafting procedure that is sometimes necessary to build up the bone show that it can support a dental implant.
During endoscopic sinus surgery, a doctor uses an endoscope to view the inner cavities of the nose (A and B). Using special instruments, the doctor opens the sinuses to alleviate problems with sinusitis (C and D). (Illustration by GGS Inc.)

Other Information
Functional endoscopic sinus surgery (FESS) is a minimally invasive surgical procedure that opens up sinus air cells and sinus ostia (openings) with an endoscope.
The use of FESS as a sinus surgical method has now become widely accepted; and the term "functional" is meant to distinguish this type of endoscopic surgery from nonendoscopic, more conventional sinus surgery procedures.
Purpose
The purpose of FESS is to restore normal drainage of the sinuses. Normal function of the sinuses requires ventilation through the ostia (mouth-like opening) and is facilitated by a mucociliary transport process that maintains a constant flow of mucus out of the sinuses. All sinuses need ventilation to prevent infection and inflammation, a condition known as sinusitis. In healthy individuals, sinus ventilation occurs through the ostia into the nose. The sinuses open into the middle meatus (curved passage in each nasal cavity) under the middle turbinate (thin, bony process that is the lower portion of the ethmoid bone in each nasal cavity), which together are known as the osteomeatal complex, the key area of the nose. The hair-like cilia direct the flow of mucus toward the ostia.
