When it does not close spontaneously or if it is not treated, it remains permeable and epithelializes to develop into an oro-antral fistula (OAF) and can cause maxillary sinusitis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Cases presentation:<\/jats:title>\n                    <jats:p>The authors present through 5 clinical cases the different steps of the surgical protocols opting for the buccal fat pad flap and the advanced buccal flap to treat OAF\/OAC.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical discussion:<\/jats:title>\n                    <jats:p>Surgical closure of the OAC within 48 h is recommended to avoid complications. Several alternative techniques have been described over the years for the management of the OAC and OAF, with their advantages and limitations. The most commonly used surgical flaps are of two types: the advanced buccal flap and the buccal fat pad (BFP) flap.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>The adequate availability of the advanced buccal flap and the buccal fat pad (BFP) flap in the majority of patients, the easy handling, the minimal donor site morbidity as well as the excellent blood supply make them perfect flaps for the closure of OAF\/OAC. However, follow-up remains a key point and very important to avoid complications. The present case series was limited by the small number of patients and the authors recommend a study with larger groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Highlights<\/jats:title>\n                  <\/jats:sec>","DOI":"10.1016\/j.ijscr.2022.107436","type":"journal-article","created":{"date-parts":[[2022,7,20]],"date-time":"2022-07-20T23:08:37Z","timestamp":1658358517000},"page":"107436","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":25,"title":["Diagnosis and Management of oro-antral fistula"],"prefix":"10.1097","volume":"97","author":[{"given":"Asma","family":"Azzouzi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lamiae","family":"Hallab","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saliha","family":"Chbicheb","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-64-20260309","doi-asserted-by":"crossref","first-page":"58","DOI":"10.5125\/jkaoms.2020.46.1.58","article-title":"Closure of oroantral fistula: a review of local flap techniques","volume":"46","author":"Kwon","year":"2020","journal-title":"J.
