Closure of OAC with Buccal Fat Pad
I show here, the closure of an OAC that developed after
the removal of the UR7 (upper right 2nd molar).

The 55 year old patient was referred to the Oral Surgery
Department, complaining of a stuffy right maxillary sinus,
with discharge from the sinus & fluid from nose after
drinking.  This started almost immediately after his UR7
was removed.
Radiographs of the Mouth & Close-up of the Area Effected
Both the buccal & palatal mucosae have been mobilised.
