Surgical access to the maxillary sinus is usually possible via a minimally invasive endoscopic approach through the nose or the oral vestibule.

Maxillary sinus surgery

The maxillary sinus is a cavity, lined with mucous membrane, which is one of the paranasal sinuses. The tooth roots in the upper jaw are in close proximity to the maxillary sinus; in many cases the roots protrude into the cavity.

The teeth of the upper jaw are therefore frequently the cause of maxillary sinus problems, especially where these symptoms occur on only one side.

This close proximity means that, when teeth are removed in the upper jaw, the oral cavity and maxillary sinus may be linked (oroantral communication). If this connection is not sealed, wound-healing disorders may occur, as may subsequently a chronic inflammation of the maxillary sinus. In more severe cases it is even possible that fluids or food may enter the maxillary sinus and hence the nose. An oroantral communication should therefore always be closed by means of a minor surgical procedure.

The maxillary sinus may, however, become inflamed even without a connection to the oral cavity, as where inflammatory processes spread from tooth roots through the immediate vicinity of the site. These processes can have different manifestations, as for example in the form of a cyst or the accumulation of pus.

In rare cases, a tooth may be displaced into the maxillary sinus, or foreign material introduced during dental treatment may enter the maxillary sinus via the root ends, which also leads to inflammation or reactions of the mucous membrane in the sinus.

The cause of maxillary sinus inflammations may, however, also be insufficient ventilation. This condition can arise if the mucous membranes of the paranasal sinuses are swollen due to chronic inflammation.

Typical symptoms of an inflamed maxillary sinus are dull, pressing pain that increases when the sufferer leans the head forward. The maxillary sinuses are often sensitive to pressure and to being tapped.

Initial therapy for a maxillary sinus inflammation is antibiotic treatment with, if necessary, irrigation to treat the acute inflammation in the sinus and thus alleviate the acute symptoms. The cause should then be remedied in between episodes of inflammation. An accurate diagnosis is required here, as lasting freedom from symptoms will come only when the cause of the inflammation is permanently removed.

Close cooperation with ENT specialists is very important to us in the diagnosis and therapy of maxillary sinus problems.

If surgery of the maxillary sinus is necessary, this can be carried out – depending on how large an area is affected – under local anaesthetic, twilight sedation or general anaesthetic. Maxillary sinus surgery is, in most cases, possible via a minimally invasive endoscopic approach through the nose or the oral vestibule.
