Injection of the greater palatine canal is a useful technique in the control of posterior epistaxis. The arterial blood supply to the inferior turbinate is via a single descending branch of the sphenopalatine artery. We conjectured that injection of the pterygopalatine fossa, via the greater palatine canal, would result in a reduction of blood flow to the inferior turbinate. In this study injection of the pterygopalatine fossa caused only a 4.7 per cent decrease in blood flow to the inferior turbinate mucosa (<jats:italic>p<\/jats:italic>0.571). Elevation of the head by an angle of 20 degrees reduced nasal mucosal blood flow by 38.3 per cent (<jats:italic>p<\/jats:italic>&lt;0.0001). Depression of the head by an angle of 20 degrees increased nasal mucosal blood flow by 74.7 per cent (<jats:italic>p<\/jats:italic>&lt;0.0001). We conclude that there is an adequate collateral blood circulation to the anterior portion of the inferior turbinate.<\/jats:p>","DOI":"10.1017\/s0022215100132943","type":"journal-article","created":{"date-parts":[[2007,11,30]],"date-time":"2007-11-30T10:14:52Z","timestamp":1196417692000},"page":"124-128","source":"Crossref","is-referenced-by-count":14,"title":["Laser-Doppler blood flowmetry measurement of nasal mucosa blood flow after injection of the greater palatine canal"],"prefix":"10.1017","volume":"110","author":[{"given":"Paul","family":"Gurr","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vincent","family":"Callanan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Baldwin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2007,6,29]]},"reference":[{"key":"S0022215100132943_ref016","doi-asserted-by":"crossref","first-page":"1245","DOI":"10.1288\/00005537-199011000-00022","article-title":"Incisive canal and pterygopalatine fossa injection for hemostasis in septorhinoplasty","volume":"100","author":"Williams","year":"1990","journal-title":"Laryngoscope"},{"key":"S0022215100132943_ref015","first-page":"932","article-title":"Injection of the pterygopalatine fossa with glycerin for posterior epistaxis","volume":"76","author":"Weingarten","year":"1972","journal-title":"Transactions of the American Academy of Ophthalmology and Otology"},{"key":"S0022215100132943_ref014","doi-asserted-by":"crossref","first-page":"580","DOI":"10.1288\/00005537-198805000-00022","article-title":"Greater palatine foramen injection made easy","volume":"98","author":"Stankiewicz","year":"1988","journal-title":"Laryngoscope"},{"key":"S0022215100132943_ref002","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215100041578"},{"key":"S0022215100132943_ref001","first-page":"94","article-title":"Greater palatine canal injection: an alternative to the posterior nasal packing and arterial ligation in epistaxis","volume":"15","author":"Bharadwaj","year":"1986","journal-title":"Journal of Otolaryngology"},{"key":"S0022215100132943_ref004","doi-asserted-by":"publisher","DOI":"10.1016\/0091-6749(88)90186-8"},{"key":"S0022215100132943_ref008","doi-asserted-by":"publisher","DOI":"10.3109\/00016488509119155"},{"key":"S0022215100132943_ref012","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215100117815"},{"key":"S0022215100132943_ref003","doi-asserted-by":"crossref","first-page":"1276","DOI":"10.1152\/jappl.1984.57.4.1276","article-title":"Response of nasal blood flow to neurohormones as measured by laser-Doppler velocimetry","volume":"57","author":"Druce","year":"1984","journal-title":"Journal of Applied Physiology: Respiration, Environment and Exercise Physiology"},{"key":"S0022215100132943_ref005","first-page":"252","volume-title":"Laser- Doppler Flowmetry","author":"Druce","year":"1980"},{"key":"S0022215100132943_ref013","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4757-2083-9"},{"key":"S0022215100132943_ref007","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4757-2083-9_4"},{"key":"S0022215100132943_ref009","doi-asserted-by":"publisher","DOI":"10.3109\/00016488609108653"},{"key":"S0022215100132943_ref011","first-page":"85","article-title":"A method for control of posterior nasal hemorrhage","volume":"87","author":"Padrnos","year":"1968","journal-title":"Archives of Otolaryngology"},{"key":"S0022215100132943_ref010","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":"Journal of the Royal Society of Medicine"},{"key":"S0022215100132943_ref006","doi-asserted-by":"publisher","DOI":"10.3109\/00016488609132839"}],"container-title":["The Journal of Laryngology &amp; Otology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0022215100132943","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,2,19]],"date-time":"2024-02-19T21:18:51Z","timestamp":1708377531000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0022215100132943\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1996,2]]},"references-count":16,"journal-issue":{"issue":"2","published-print":{"date-parts":[[1996,2]]}},"alternative-id":["S0022215100132943"],"URL":"https:\/\/doi.org\/10.1017\/s0022215100132943","relation":{},"ISSN":["0022-2151","1748-5460"],"issn-type":[{"value":"0022-2151","type":"print"},{"value":"1748-5460","type":"electronic"}],"subject":[],"published":{"date-parts":[[1996,2]]}}}
