OPS-Code 5-225.4:
Operations on the paranasal sinuses: Plastic reconstruction of the paranasal sinuses: Closure of an alveolar antral fistula
An connection between your maxillary sinus and your oral cavity was surgically closed.
The paranasal sinuses are air-filled cavities in the skull. They are each connected to the nasal cavity via an opening that forms the inside of the nose. The paranasal sinuses are lined internally with mucous membrane. There are four different paranasal sinuses.The maxillary sinus is in the upper jawbone.
The oral cavity forms the interior of the mouth. It contains the teeth and the tongue.The maxillary sinus and oral cavity are not normally connected. A connection between the maxillary sinus and oral cavity may occur as a result of an operation, for example.
You had a connection between your maxillary sinus and upper jawbone. This affected the area of the upper jawbone in which your teeth are anchored. Your operation closed this connection. For this purpose, mucous membrane or bone was taken from another part of your mouth, for example. The mucous membrane or bone was then inserted to close the connection.
