Abstract
AGREDA MORENO, Beatriz; URPEGUI GARCIA, Ángel and VALLES VARELA, Héctor. Closure of an oroantral fistula using bone cement and a jugal mucosa flap. Rev Cubana Cir [online]. 2012, vol.51, n.1, pp. 71-78. ISSN 0034-7493.
The oroantral fistula is a solution of pathological continuity between the maxillary sinus and the oral cavity, frequently produced after a teeth extraction in most of cases of the first or second molars. The commonest symptom provoked is an acute sinusitis evolving to chronicity if the fistula remains. The diagnosis is made by transalveolar, orthopantography or dental computerized tomography. Its surgical closure is necessary when the fistula has more than 3 mm or not seal by itself in three weeks. For it, there are some techniques using different materials and flaps where its objective is to occlude the bone defect as well as the mucous one thus solving the fistula and the sinus problem.
