Closure of a Mouth-Sinus Communication with a Buccal Advancement Flap
This mouth-sinus hole (Oro-Antral Communication) was created when the patient had his Upper Left 6 (UL6) / Upper Left 1st Molar removed (the patient also had all his other teeth removed at the same time).
After the swelling and soreness of the Full Dental Clearance had started to settle, the patient was referred back to the hospital department as he had noticed that when he drank, fluid came out of his nose.
