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.
