Abstract
|
|
|
|
An oroantral fistula refers to an abnormal connection between the oral cavity and the maxillary sinus, which can result in chronic maxillary sinusitis. Combining a buccal fat pad and buccal advancement flap has certain limitations when correcting bone defects and providing prosthetic rehabilitation supported by implants. Autografts have been recommended, particularly for larger defects or when conservative methods are ineffective. This case report describes particulate autogenous bone grafts with a pouch graft technique to address a long-standing oroantral fistula and chronic sinusitis that did not improve after endoscopic sinus surgery. The proposed approach using particulate autogenous bone grafts with a pouch graft technique offers a solution for successfully closing the fistula and resolving the symptoms related to sinus issues. Oroantral fistulas need to be managed to prevent complications. Further research will be needed to evaluate the long-term ability of this method to regenerate bone.
