Video of Maxillary Sinus Cyst Excision

Generally, maxillary sinus cysts are a common benign lesion of the paranasal sinuses, usually formed when the duct openings of mucosal glands in the maxillary sinus become blocked, leading to mucus retention within the sinus mucosa. This condition can be treated surgically. The specific procedure is as follows:

1. Administer general anesthesia to ensure patient comfort during the surgery.

2. On the smooth surface of the nasal cavity and maxillary sinus floor, use a scalpel or bone rongeur to lift the cyst wall, ensuring adequate opening of the maxillary sinus ostium.

3. Aspirate the cystic fluid from the maxillary sinus, then inject an appropriate amount of mucosal shrinking agent into the cyst cavity to prevent recurrence of the cyst.

4. Pack the natural ostium of the maxillary sinus with Vaseline gauze to prevent leakage of cystic fluid.

5. Irrigate the maxillary sinus cavity with normal saline to ensure removal of residual cyst material and to help prevent infection.

This surgical procedure requires specialized expertise. It is recommended to undergo the operation at a正规 medical facility under the guidance of qualified physicians to minimize surgical risks. After surgery, maintain a light diet and avoid spicy or irritating foods to promote proper recovery.
