Closure of a Mouth-Sinus Communication with a Palatal Rotation Flap
This mouth-sinus hole (Oro-Antral Fistula) was created when the patient had his Upper Left 7 (UL7) / Upper Left 2nd Molar removed.  The
X-ray (a PA) shows the bony defect behind the upper left premolars.

With the creation of the
OAF, the floor of the maxillary sinus has herniated through into the mouth & has created an antral polyp.
Diagram showing the first stages of the closure of an OAF using a Palatal Rotation Flap.

In this case, the antral polyp & the OAF is excised.

Diagram showing the final stage of the closure of an OAC using a Palatal Rotation Flap.

The Palatal Rotation Flap has been brought buccally and sutured into place.
Last Updated 2nd May 2020
Incisions are made into the palatal mucosa to create a flap that will cover the OAF.
