Abstract
Oroantral communication (OAC) or fistula (OAF) is an open pathological communication between the oral cavity and maxillary sinus which mostly occurs as a result of extraction of upper molars and premolars, iatrogenic complications or from dental infections, osteomyelitis, radiation therapy or trauma. Several alternative techniques modalities have been described throughout the years for the management of OAC and OAF which show both advantages and limitations. The most employed surgical flaps are of three types: advanced buccal flap, palatal flap and buccal fat pad flap. The authors present two clinical cases: oroantral communication and oroantral fistula, both were treated by using buccal advancement flap.
Highlights
Oroantral communication (OAC) is the space created between the maxillary sinus and the oral cavity, which, if not treated, will progress to oroantral fistula (OAF) or chronic sinus disease [1]
Many techniques to close OAC/OAF have been described in the literature, such as buccal flap, palatal flap, buccal fat pad and relate modifications
The goal of this paper is to reports two cases of OAC/OAF which have been successfully treated by surgical buccal advancement flap technique
Summary
Oroantral communication (OAC) is the space created between the maxillary sinus and the oral cavity, which, if not treated, will progress to oroantral fistula (OAF) or chronic sinus disease [1]. These complications occur most commonly during extraction of upper molar and premolar teeth (48%). Many techniques to close OAC/OAF have been described in the literature, such as buccal flap, palatal flap, buccal fat pad and relate modifications They are their own advantages and disadvantages depending on the cases and the size of the defects occurred. The goal of this paper is to reports two cases of OAC/OAF which have been successfully treated by surgical buccal advancement flap technique
