Functional Endoscopic Sinus Surgery is the abbreviation for FESS. It is a surgical treatment for curing blocked sinuses. A sinus is the hollow cavity present in the bones of head and the face. Swelling and inflammation in the sinus openings are common symptoms of sinusitis. Bad breath, headache, greenish or yellowish discharge from your nose and toothache are few other symptoms.

FESS surgery is an option only when all the other medications and lifestyle changes fail. Acute and chronic sinusitis are the two types of sinusitis surgery. Acute sinusitis is a short term process lasting for less than four weeks, the condition goes away without any medication. Whereas, chronic sinusitis lasts for 12 weeks and more. An acute sinusitis after few weeks gives way to chronic sinusitis.
Prior to the surgery, the patient needs to inform the doctor about the medicines prescribed to him. Sometimes, patients are allergic to some drugs, in such cases, this needs to be informed to the doctor. In many cases the doctor advises the patient to go off some blood-thinning medicines he maybe taking. The patient is also expected to be on an empty stomach post midnight before the day of surgery.
In an FESS procedure, the doctor uses an endoscope to examine and extract the affected tissues. CT scans and physical examination give the doctor an idea as to which sinuses need to be operated on. Sinus openings are enlarged for drainage of sinusitis. The surgery also involves removing blockages to eliminate the mucus out of the openings. Chances of a recurrence are thereby minimised due to surgery.
Post surgery, the doctor prescribes nasal drops to be sprayed 5-6 times daily. The drops should be sprayed towards the wall of the nose and not in the centre. The patient should also as far as possible try to avoid blowing or rubbing or pressing his or her nose. Consuming ice creams and cold foods also should be refrained from. Staying away from dusty places and smokey environs also is helpful.
