This in turn will help oral surgeons to modify treatment options in patients with these risk factors and to rationalize decision making in managing this accidental occurrence to avoid future oroantral fistula
and its complications.
It has been shown that the presence of an oroantral fistula
can predispose one to actinomycosis of the paranasal sinuses [5, 8].
Berger, "Oral-maxillary sinus fistula (oroantral fistula
): clinical features and findings on multiplanar CT," American Journal of Roentgenology, vol.
Clinical evaluation revealed the presence of oroantral fistula
of 10 X 6 [mm.sup.2].
Endoscopic endonasal approach should be the surgical choice unless oroantral fistula
It is possible that a temporary oroantral fistula
formed during the extraction of one or more of our patient's teeth, allowing for the deposit of a small amount of vegetable matter into the sinus.
In the event of an oroantral fistula
or when the foreign body has a considerable size, a direct approach may be needed.
Partial maxillectomy defects 25 were the most common defects reconstructed with BFP flap followed by cheek mucosal defects i.e., 8 patients, 7 patients were treated for maxillary tuberosity defects, 3 for retromolar area defects, 2 for oral submucous fibrosis and 5 for oroantral fistula
. (Fig 3).

The Caldwell-Luc incision was closed, and attention was then directed to the residual oroantral fistula
, which was excised and closed primarily.
Key Words: Minor oral surgery, dental extractions complications, buccal fat pad flap, oroantral fistula
Often they result from the escape of material through an oroantral fistula
or from trauma.
The objective of the study was to determine the most vulnerable sites and side involved in oroantral fistula
The aim of this study was to evaluate and analyze the occurrence, characteristics and treatment outcome of oroantral fistula
in 29 patients from Sept 2004 to Nov 2009.
Osteomas are bone-forming tumors, and their occurrence in the maxillary sinus following dental extraction and surgery for oroantral fistulas
has been documented in the literature.
