Sinuses are cavities near the nasal passage. Disorders like inflammation or infections in these cavities can lead to blockages resulting into a sinusitis condition. Chronic cases stand in need for sinus surgery.
There are four types of sinuses namely:
Each of the above mentioned four sets of sinuses is an enclosed space that drains through an ostium, or opening into the nose. The sinuses are lined by mucosa which is similar to the lining of the nose. These ostia can be blocked because of inflammation or swelling of the mucosa. Cancerous, non cancerous tumors or bony structures may also create blockages in the ostium.
The lateral nasal wall consists of three turbinate bones. These bony structures are covered with a mucus membrane containing vascular channels. Any kind of inflammation or allergy can cause swelling around that area. A tear duct is responsible to drain tears from the eyes into the nose. Blockage of this duct due to any injury or sinus infection causes excess tearing of the eye. The middle meatus is the common passageway for the drainage of the maxillary, frontal and ethmoid sinuses. Inflammation or swelling in these key regions may cause blockage of the sinuses.
All the above reasons that cause blockages in the sinuses can be efficiently fixed using a Sinus Surgery. Functional Endoscopic Sinus Surgery (FESS) is a type of sinus surgery that is performed with the help of an endoscope. There are other types of sinus surgeries as well. Treatment methods for Sinus infection depends on the severity of the problem. If you are facing sinus issues, consult your physician and go for the necessary treatment option.
