Repair of Oromaxillary Fistula - Surgery Overview
An oromaxillary fistula is an abnormal passageway between one of
the sinuses on either side of your nose (maxillary sinuses ) and the roof of your
mouth. It may develop as a birth defect (linked with a
as a complication of removing a
tooth, or from infection or trauma. Sometimes the roots of a tooth are so close
to the bone under a maxillary sinus that the bone is damaged when the tooth is
removed. This can open a passage between the mouth and sinus.
Before surgery, you may have an imaging test, such as a
computed tomography (CT) scan, to help the doctor plan
A surgeon may choose one of several techniques to close the
fistula. One of the most common methods is called flap advancement. It involves
cutting a U-shaped flap of skin in the side or roof of the mouth (sometimes
both) and stretching the flap over the fistula. Sometimes a surgeon will place
a piece of medical-grade foil over the opening and then stitch the skin flap
over the foil.
You probably will have
general anesthesia, which means you will be
unconscious during the operation.
