title: Surgical treatment of oroantral fistulas: a clinical study of 23 cases.
abstract: Oroantral communication can be defined as a pathologic space created between the maxillary sinus and the oral cavity. This communication and subsequent formation of a chronic oroantral fistula is a common complication often encountered by oral and maxillofacial surgeons. Although various techniques have been proposed in published studies, long-term successful closure of oroantral fistulas is still one of the most difficult problems confronting the surgeon working in the oral and maxillofacial region. The decision of which treatment modality to use is influenced by many factors, such as the amount and condition of tissue available for repair, the size and location of the defect, the presence of infection, the time to the diagnosis of the fistula, and, even, the surgeon's past experience. In the present study, 23 patients with a chronic oroantral fistula who underwent surgical correction at Istanbul University Faculty of Dentistry, Department of Oral and Maxillofacial Surgery from 2002 to 2009 were included. The fistulas were treated with a buccal advancement flap in 10 patients and a palatal island flap in 13 patients. The advantages, limitations, and complications of each technique are discussed.
