Maxillary antrostomy may be performed to treat chronic sinusitis.
Maxillary antrostomy is a type of surgery for chronic sinusitis. It involves unblocking and/or widening the place where the sinuses drain into the nose, as well as clearing the sinus opening and relieving congestion. This type of surgery is quite safe and carries only a small risk of complications or adverse effects.
The maxillary sinuses are located behind the cheekbones and normally drain into the nose. When this drainage passage is blocked, patients may experience headaches, facial pain, or sinus congestion, which can significantly affect quality of life. Acute maxillary sinus infection lasts for a short time and chronic sinus infections last for more than 12 weeks. Maxillary antrostomy is done for chronic conditions and surgery is usually only performed if everything else has been ineffective. Medical treatments, such as antibiotics, are the first course of action for sinus infections.
After maxillary antrostomy, it is important to keep sealing material, such as gauze, in the nose until instructed to remove it.
Most sinus surgeries are done using the functional endoscopic sinus surgery (FESS) technique, which is done through the nostrils rather than cutting through the face. This is safer for the patient and allows for a faster recovery time without facial scarring. Maxillary antrostomy is usually done under general anesthesia. A small viewing instrument called an endoscope is inserted through the nostril to view the drainage opening. Small surgical instruments are inserted next to the endoscope and used to remove the blockage.
If a maxillary antrostomy is unsuccessful, more complicated surgery may be attempted.
Maxillary antrostomy is generally a safe procedure and carries a small risk of complications. Infection, bleeding, and allergic reactions to anesthesia or other medications are standard risks of any surgery. It is also possible that surrounding structures, such as the tear ducts or eyes, may be damaged during surgery. Even after sinus surgery, the patient may have an occasional sinus infection that requires antibiotics. If maxillary antrostomy is unsuccessful in restoring normal sinus function and relieving symptoms, a more complicated surgery known as the Caldwell-Luc procedure may be necessary, which involves creating a new drainage opening in the sinus cavity.
A maxillary antrostomy may be performed to clear sinus openings and relieve congestion.
Most patients experience pain and swelling for a few days to a few weeks after maxillary antrostomy surgery and may experience some bleeding. It is important to leave any packing material, such as gauze, inside your nose until instructed to remove it, even if this can be uncomfortable and make breathing through your nose difficult. Patients should avoid blowing their nose or performing strenuous activities for about a week after surgery. Your doctor may recommend saline nasal spray or other nasal care to help your nose and sinuses heal with minimal internal scarring.
