Maxillary Middle Meatal Antrostomy Surgery

. Posted in SURGERY

In maxillary middle meatal antrostomy surgery, the natural ostium of the maxillary sinus is opened. This technique usually obviates the need for the surgeon to remove polyps in the maxillary sinus: it has been shown that they can resolve themselves if normal drainage patterns are returned. However, it is up to the discretion of the surgeon whether to remove any polyps. In any event, if there is an antrochoanal polyp (a polyp that starts to grow from the wall of the sinus and then passes through the opening to the maxillary sinus into the nose), the surgeon should remove not only the polyp as it protrudes into the airway but also the base in the maxillary sinus. Removing this polyp and its base offers the greatest chance of cure. Furthermore, if there is a cyst in the maxillary sinus, the surgeon may want to unroof the cyst, or remove it completely. No matter what the surgeon does during the procedure, polyps and cysts can return or get larger.
