However potential complications connected to this method, such as oronasal fistula (ONF), have not been described in the literature to date.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation:<\/jats:title>\n                    <jats:p>We report the case of a female patient with severe atrophy of the edentulous maxillary alveolar ridge with type 2 diabetes (T2D). Initially, a sinus floor augmentation was performed, followed by a failed placement of dental implants. Afterwards, HLFO with simultaneous interposition of iliac bone grafts was conducted. Subsequently, an oronasal communication occurred in the antral maxilla. As several local flaps had not achieved sufficient results, a melolabial interpolated island flap was carried out, yielding satisfactory results.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion:<\/jats:title>\n                    <jats:p>Failed implant treatment or bone augmentation procedures in combination with T2D may have resulted in significant tissue irritation and subsequent wound healing complications in the antral maxilla, leading to an ONF.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>In this case, an ONF occurring after HLFO was described for the first time. The melolabial interpolated island flap proved to be an outstanding long-term solution for the management of an anterior ONF occurring after HLFO over a period of 10 years. Less invasive treatment options including zygomatic implants should be taken into consideration for the treatment of such patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Highlights<\/jats:title>\n                  <\/jats:sec>","DOI":"10.1016\/j.ijscr.2022.106939","type":"journal-article","created":{"date-parts":[[2022,3,14]],"date-time":"2022-03-14T17:30:29Z","timestamp":1647279029000},"page":"106939","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["Melolabial interpolated island flap for reconstruction of an anterior oronasal fistula after horseshoe Le Fort I osteotomy with iliac bone grafts interposition - A case report"],"prefix":"10.1097","volume":"93","author":[{"given":"Benedikt","family":"Schneider","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Florian","family":"Pfaffeneder-Mantai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pascal","family":"Gr\u00fcn","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Oliver","family":"Meller","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katharina","family":"Dobbertin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dritan","family":"Turhani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","reference":[{"key":"R1-51-20260304","doi-asserted-by":"crossref","first-page":"142","DOI":"10.3390\/dj2040142","article-title":"Oronasal fistula and complete edentulism: what to do?","volume":"2","author":"Kaur","year":"2014","journal-title":"Dentistry J"},{"key":"R2-51-20260304","doi-asserted-by":"crossref","first-page":"1041","DOI":"10.1097\/00006534-199106000-00005","article-title":"Cleft palate fistulas: a multivariate statistical analysis of prevalence, etiology, and surgical management","volume":"87","author":"Cohen","year":"1991","journal-title":"Plast.
