What is an antrostomy?

Antrostomy is a surgical procedure that creates an opening (stoma) into the maxillary sinus, which is a hollow cavity located in the cheekbone. It is typically performed to treat chronic sinusitis, a condition characterized by inflammation and infection of the sinuses. The procedure involves removing a small portion of the bone and tissue to allow for drainage and ventilation of the sinus.

Antrostomy can be performed using different techniques. One common method is endoscopic antrostomy, which uses a thin, flexible tube with a camera (endoscope) to visualize and access the sinus. The surgeon inserts the endoscope through the nose and into the sinus, where they can remove any blockages, clear out infection, and create the stoma. Another technique is Caldwell-Luc antrostomy, which involves making an incision in the upper gum or cheek to directly access the sinus.

After the antrostomy procedure, a small stent or tube may be placed in the stoma to help keep it open and facilitate drainage. The patient may experience some discomfort, swelling, and bleeding for a few days, and they may need to take antibiotics to prevent infection. The recovery period typically lasts several weeks, and regular follow-up visits with the doctor are necessary to monitor the healing process and ensure the success of the procedure.
