Oroantral communication

Oroantral communication is a pathological state during which there is a communication between the maxillary sinus and the oral cavity. It occurs usually after extractions of rear teeth of the upper jaw. The upper jaw’s rear teeth’s roots, are many times directly related with the sinus’ mucous membrane. In these cases, due to anatomical variation, even a non-traumatic extraction of a tooth may have an occurrence of communication between the oral cavity and the sinus as a result, via the tooth’s socket.

If not dealt with, a chronic oroantral fistula will occur and cause a chronic odontogenic sinusitis. This is a major complication that requires direct convergence from an Oral and Maxillofacial Surgeon expert.

The most common convergence of communication technique is the production of a propulsive tissue from the mucous membrane. Palatinate tissue can also be used.
