What are Sinuses?

Sinuses are hollow air spaces in the face. These are cavities located within the skull or bones of the head surrounding the nose-

1. Frontal sinuses over the eyes in the brow area

2. Maxillary sinuses inside each cheekbone

3. Ethmoid sinuses just behind the bridge of the nose and between the eyes

4. Sphenoid sinuses behind the ethmoids in the upper region of the nose and behind the eyes

Each sinus has an opening into the nose for the free exchange of air and mucus, and each is joined with the nasal passages by a continuous mucous membrane lining. Therefore, anything that causes a swelling in the nose an infection, an allergic reaction, or another type of immune reaction also can affect the sinuses. Air trapped within a blocked sinus, along with pus or other secretions may cause pressure on the sinus wall. The result is the sometimes intense pain of a sinus attack. Similarly, when air is prevented from entering a paranasal sinus by a swollen membrane at the opening, a vacuum can be created that also causes pain. This kind of pain is often experienced in an air journey during the descent.


Sinusitis simply means your sinuses are infected or inflamed.

Acute sinusitis- lasts for 3 weeks or less.

Chronic sinusitis- lasts for 3 to 8 weeks but can continue for months or even years.

Endoscopic sinus surgery (FESS)

Functional endoscopic sinus surgery (FESS) is a minimally invasive surgical treatment which uses nasal endoscopes to enlarge the nasal drainage pathways of the paranasal sinuses to improve sinus ventilation. In most situations, the surgeon will employ endoscopic techniques that allow better and more precise visualization without the need for external incisions.

Advantages of Sinus Surgery-

Less swelling,

Minimal bleeding

Minimal discomfort and Reduced Post operative pain

Shorter hospital stay

Less scarring with minimal incisions

Quicker Recovery

Sinus surgery, involves the re-routing of existing sinus pathways in addition to removal of diseased tissue. Post-operative care is as equally important as the surgery itself.

After endoscopic sinus surgery

1. Dressing: Light red to clear drainage from the nose is normal for 5-10 days following surgery. The outside gauze dressing needs to be changed when soiled or saturated.. Dressing is usually kept in place for 2 days. You are required to come to the clinic for its removal.

2. Packing: Nasal packing is usually used after surgery. Do not attempt to blow the nose with packing in place. It is normal to have bad breath or small a foul odor while the packing is in place.

3. Medications: Headache, sinus, or nasal discomfort is common after surgery and you should have medication for this. Antibiotics and/or a moisturizing saline spray may be prescribed.

4. Activity: No swimming or strenuous activities should be performed for 10-14 days after surgery as this might because bleeding. You may resume your routine work from the 5th day onwards.

5. Diet: Eat and drink normally. Avoid alcoholic beverages while taking medications.

6. Saline Irrigations: Ten days after your nasal surgery, saline irrigations are recommended to reduce crusting and to keep the sinus opening clear. Mix 1 teaspoon table salt and 1 tablespoon baking soda in ½ liter boiled, warm water. Lean over a sink and irrigate both nasal passages. Irrigate twice a day, morning and evening.


You will need to be seen by your doctor for follow-up every 10 days following surgery for post operative cleaning. Specific instructions will be given to you at the time of discharge. An appointment is necessary and should be made before leaving the hospital When to obtain immediate care?
