The centre point of the foramen lies 59\u00a0mm from the anterior nasal spine at 22\u00b0 elevation above the plane of the hard palate and 48\u00a0mm from the piriform aperture. We discuss how these data could be used to facilitate intra-operative location of the sphenopalatine foramen in difficult cases.<\/jats:p><\/jats:sec>","DOI":"10.1017\/s0022215109004344","type":"journal-article","created":{"date-parts":[[2009,1,8]],"date-time":"2009-01-08T09:27:18Z","timestamp":1231406838000},"page":"742-745","source":"Crossref","is-referenced-by-count":13,"title":["Mapping surgical coordinates of the sphenopalatine foramen: surgical navigation study"],"prefix":"10.1017","volume":"123","author":[{"given":"L","family":"Hadoura","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C","family":"Douglas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G W","family":"McGarry","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D","family":"Young","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2009,1,8]]},"reference":[{"key":"S0022215109004344_ref3","first-page":"300","article-title":"Posterior epistaxis:systematic review on the effectiveness of surgical therapies","volume":"43","author":"Feusi","year":"2005","journal-title":"Rhinology"},{"key":"S0022215109004344_ref10","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-199801000-00024"},{"key":"S0022215109004344_ref7","doi-asserted-by":"crossref","first-page":"728","DOI":"10.1177\/014107689108401212","article-title":"Cadaver studies of the anatomy of arterial supply to the inferior turbinates","volume":"84","author":"Padgham","year":"1991","journal-title":"J R Soc Med"},{"key":"S0022215109004344_ref4","first-page":"290","article-title":"Abord endonasal de la fosse Pterygo-Maxillaire LXXIII Cong.
