Cystostomy of the tooth

What is a cystostomy of the tooth?

A cystostomy is a treatment procedure for large cysts (chambers in the jawbone filled with fluid), which makes it possible to spare adjacent tooth roots and nerves. The mucous membrane and the jawbone are opened above the cyst. Access to the cyst is created through a small incision window.

The so-called cyst bellows remains in the bone. Thus, a secondary bay to the oral cavity is formed, which is constantly decreasing in size, since the cyst cannot grow any more due to the opening. The cavity decreases in size and the cyst bellows is converted into oral mucosa after a few weeks.

What are the indications for a cystostomy?

There are various indications for performing a cystostomy. Firstly, a cystostomy is performed for very large cysts with thin bone walls, where there is a risk that the bone walls will break during another operation or in the near future. Furthermore, the method is used for cysts in the lower jaw where the alveolar nerve or the neighboring teeth would be at risk if they were removed. If the cysts are infected, a cystostomy is also indicated. Furthermore, cysts in the anterior region of the upper jaw are an indication, as there is a risk that they border on the bony floor of the nose and damage it.

Preparation for a cystostomy

A cystostomy must be prepared specifically. Depending on the course of the surrounding nerves and the extent of the cyst, the operation must be well planned. As a patient, it is important to be aware that the follow-up treatment may take several months.

It is characterized by constant own flushing and changing of tamponades. If necessary, further follow-up treatments are necessary. In preparation for a cystostomy, all possible complications that may result from the operation and treatment must always be clarified. These include vascular or nerve injuries, inflammatory reactions or secondary bleeding.
