antrostomies

Antrostomy is a surgical procedure that involves creating an opening into the maxillary sinus, also known as the antros. This procedure is most commonly performed to treat chronic sinusitis, a condition characterized by inflammation of the sinus lining that persists for 12 weeks or longer. By creating an opening, the surgeon aims to improve drainage and ventilation of the sinus, thereby reducing inflammation and alleviating symptoms.

There are several approaches to performing an antrostomy. The traditional method involves an external incision, often through the canine fossa, which is the area below the cheekbone. However, minimally invasive endoscopic techniques have become increasingly popular. In endoscopic antrostomy, a small, flexible tube with a camera (an endoscope) is inserted through the nostril, allowing the surgeon to visualize and operate within the sinus without external incisions. Another technique is the Caldwell-Luc procedure, which involves an incision in the mouth above the upper teeth.

Indications for an antrostomy typically include recurrent or chronic sinusitis that has not responded to medical management, such as antibiotics and nasal steroids. Other reasons may involve the presence of nasal polyps within the maxillary sinus, fungal sinusitis, or tumors of the sinus.

The procedure is generally safe, but as with any surgery, there are potential risks and complications. These can include bleeding, infection, damage to surrounding structures like the teeth or eye, or numbness in the cheek area. Post-operative care usually involves nasal rinsing and avoiding forceful nose blowing to promote healing and prevent complications. Recovery time varies, but many patients experience significant relief from their sinus symptoms after the procedure.
