Revista Cubana de Cirugía , 2012,
Abstract: Una fístula oroantral es una solución de continuidad patológica entre el seno maxilar y la cavidad oral, producida frecuentemente tras una extracción dentaria, en la mayoría de los casos, del primer o segundo molar. El síntoma más común que provoca es una sinusitis aguda, que evolucionará a la cronicidad si la fístula permanece. El diagnóstico se realiza mediante endoscopia transalveolar, ortopantografía o tomografía computarizada dental. Su cierre quirúrgico es necesario cuando la fístula tiene más de 3 mm, o no sella por sí misma en 3 semanas. Existen, para ello, varias técnicas, usando distintos materiales y colgajos, cuyo fin es ocluir, tanto el defecto óseo, como el mucoso, para solucionar así a la vez la fístula y el problema sinusal. 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.

Abstract: Oroantral fistula is pathologic communication between oral cavity and maxillary sinus, usually localized between antrum and buccal vestibulum. Persisting OAF always causes chronic maxillary sinusitis. A technique for closure of a large oroantral fistula with resorbable collagen membrane is described.
Oroantral fistula from bisphosphonate induced osteonecrosis of the jaw

Journal of Surgical Case Reports , 2010,
Abstract: Bisphosphonates like alendronic acid, disodium etidronate, and risedronate are effective for preventing postmenopausal and corticosteroid induced osteoporosis. They are also useful in the treatment of Paget’s disease, hypercalcaemia of malignancy and in bony metastases. However osteonecrosis of the jaw has been reported following intravenous bisphosphonate use and rarely in those taking them orally.Increasingly, oroantral fistulae have been shown to occur as sequelae of bisphosphonate-induced osteonecrosis of the jaw and this case report highlights a patient that presented to our ENT department and required sinus surgery in collaboration with maxillofacial surgeons.This case report aims to raise awareness among ENT surgeons to these patients on bisphosphonates that could present to them with sinus disease from oroantral fistulae. There is an on-going audit in the maxillofacial community on this emerging trend.

Abstract: Introduction: Various methods for closure of oroantral communication (OAC) and oronasal communication (ONC) have been reported. These are different based on the skill of surgeon, type of communication, size and location of defect and other factors. The purpose of this study was to evaluate the etiologic factors, location, type of treatment and surgical results in patients with oronasal and oroantral communications. Materials and Methods: In this descriptive study, between 2005-2007, 79 patients with OAC or ONC were evaluated for aforementioned factors. The data were statistically analyzed by Chi-square and Odd’s ratio tests. Results: Seventy nine patients including 9 patients with ONC and 70 patients with OAC were studied. The main etiologic factor for both OAC and ONC was tooth extraction. The surgical technique most frequently used for treatment of both OAC and ONC was suturing. Surgical failure occurred in 4 cases with OAC and 3 cases with ONC after first surgery. Conclusion: According to the results of this study, tooth extraction was the most etiologic factor for OAC and ONC. Suturing for small communications and use of a buccal fat pad flap for larger defects, seem to be the best choices for treatment.

Abstract: purpose: this paper reports the procedure used to close a late oroantral fistula using rotating flaps of the pedicled buccal fat pad. case description: a 66-year-old, male patient with leukoderma, in good general health, was referred for closure of an extensive late oroantral communication. upon clinical examination, an approximately 10-mm fistula was observed connecting the oral cavity to the maxillary sinus. an outpatient surgical procedure was performed with the use of local anesthetics to close the oroantral fistula with a rotating pedicled buccal fat pad flap. the healing of the wound and closure of the defect could be seen after a 30-day postoperative period, with complete epithelialization. conclusion: grafting of the pedicled buccal fat pad is thought to be an efficient, safe and easy alternative to a larger oroantral fistula closure. pedicled buccal fat pad grafting corrected the defect without generating any sequelae and/or great postoperative discomfort to the patient.

Abstract: Introduction: There are many causes of fistulas that involve the nasal and antral cavities or both. They may result from pathological entities or secondary to removal of tumors or maxillary cysts. However, the extraction of a maxillary molar or premolar is the most common cause of oroantral fistula. This is explained by the close relationship between the apex of these teeth and the thinness of the antral floor. When the primary fistula repair fails to heal spontaneously during the first three weeks after surgery, a secondary repair may be indicated. During treatment process of the fistulas, there are procedures to make a direct close or the use of a sliding mucosal flap, all techniques own an equal and high degree of failure. Objective: To show a case report of oroantral fistula and its closure. Case Report: A 6-month-Surgical treatment of oroantral fistula, after a tooth removal, using the buccal fat pad method as a pedicled graft associated with a sliding mucosal flap. Conclusion: The mentioned treatment is simple, complete and allows an extensive applicability in most of cases.

Abstract: Oroantral comunications are known as pathological connections occuring between the oral cavity and maxillary sinus. Early treatment of this condition prevents the development of sinusitis and fistula, as well as the need for more complex methods of treating patients and the possibility of recurrence. In this study; age, sex, etiologic factors, location of the opening, methods of treatment and early complications of 33 patients that surgically treated in Ondokuz May s University, Faculty of Dentistry, Oral and Maxillofacial Surgery Clinic between 2005-2011 were examined. 18 (54.54%) of oroantral openings were treated with buccal advancement flap, 4 (12.12%) of them were treated with palatal rotational flap, 8 (24.24%) of them were treated with iodoform gauze pack strip and the remaining 3 (9.09%) cases were treated with buccal fat pad, double-tunnel method and primary closure. In all cases, tooth extraction was the only etiologic factor. 100% (20/20) success was achieved in all patients with acute openings, while the rate was 77% (13/10) in patients with oroantral fistula.

Abstract: oroantral fistula occurs between other causes as a result of the extraction of a molar in relation to the maxillary bone. as a result the patient experiences episodes of sinusitis refractory to medical treatment. surgical repair remains the best solution, there are different techniques. the aim is to show our experience of one case operated using a rotation and advancement palatal flap and autologous bone graft. the clinical case is a 32 year old woman that two weeks after removal of upper left molar suffers repeated episodes of unilateral sinusitis. physical examination and computed tomography shown left maxillary chronic sinusitis secondary to an oroantral fistula, due to tooth extraction from maxillary bone. surgical repair is performed using a rotation and advancement palatal flap and autologous bone graft. six months following there was no complication neither recurrent sinusitis, with optimal results. oroantral fistula is a problem that has multiple options for surgery. the use of autologous bone graft and rotation and advancement palatal flap intended to be a good surgical option, allowing closure of the defect.
