Maxillary antrostomy sinus surgery

Maxillary antrostomy sinus surgery is a surgical procedure performed to provide access to the maxillary sinus, a cavity located in the facial bones above the upper teeth. This procedure is performed when it is necessary to remove cysts, tumors or polyps from the sinuses, or when it is necessary to restore or widen the opening between the sinuses and the nose.

During maxillary antrostomy sinus surgery the surgeon makes an opening in the cheek bone or upper jaw to access the maxillary sinus. After that, the surgeon carefully removes any abnormalities in the sinus and ensures that the opening between the sinus and the nose is widened to facilitate the flow of air.

This procedure usually requires general anesthesia and hospitalization, but patients generally recover within a few days after surgery. It is important to follow all of your surgeon's post-operative care instructions to ensure optimal healing and recovery.

How the surgery is performed?

Maxillary antrostomy sinus surgery is usually performed with the use of a microscope, and sometimes an endoscope is also used, which allows the surgeon to precisely examine the area being operated on. The surgery can be performed on one or both sides of the face, depending on the need.

Before surgery, the patient usually undergoes a series of preoperative tests to determine whether all medical conditions are in order. The surgery is performed in a hospital under general anesthesia.

The surgeon accesses the maxillary sinus through an opening in the bone he creates in the area of the cheek or upper jaw. Once the opening is made, the surgeon carefully lifts the lining of the sinus to gain access to the sinus cavity. The surgeon then removes any abnormalities and other problems found in the sinuses, including cysts, tumors, polyps, or other lesions. It can also remove bony material that blocks the flow of air through the opening between the sinuses and the nose. The sinus cavity and nose are tamponed with antibiotic gauze. The tampon will be removed on the fifth postoperative day with premedication with analgesics or intravenous anesthesia.

After the surgery is complete, the surgeon will place several stitches to close the opening in the bone. The patient will be monitored in the hospital until he recovers from anesthesia, after which he will be discharged home.

Postoperative care

Postoperative care includes the use of antibiotics to prevent infections and the patient may also be prescribed pain relievers. It is important to follow your surgeon's instructions for post-operative care, which may include avoiding strenuous activities and monitoring your diet to prevent complications. The patient will need to have regular follow-ups after surgery to ensure that the maxillary sinus is healing well.
