Oral surgery II: Part 2. The maxillary sinus (antrum) and oral surgery

The maxillary sinus is the largest of the four paranasal sinuses and, being anatomically adjacent to the dentate region of the maxilla, is commonly a source of problems - not simply in terms of conditions affecting the sinus but also in establishing an accurate diagnosis. As anyone who has suffered both sinusitis and a dental abscess in the posterior maxilla will tell you, the symptoms are almost indistinguishable. For this reason, a sound understanding of the maxillary sinus is an essential requisite for all dentists.
