Fourteen fresh frozen cadaver heads were obtained. All cadaver specimens underwent bilateral endoscopic wide maxillary antrostomy, frontal sinusotomy, and complete sphenoethmoidectomy. The right nasal cavity of each cadaver was sprayed with radiolabeled saline using the short nozzle (short nozzle group), while the left nasal cavity was sprayed using the long nozzle (long nozzle group). The distribution of radioactive saline within the sinus cavities was determined using single-photon emission computed tomography\/computed tomography. The distribution of the radiolabeled saline in reference with the maxillary line, vestibule, maxillary, ethmoid, sphenoid, and frontal sinus was compared between the 2 groups using Fisher exact test. The number of specimens that demonstrated radioactivity above the maxillary line is higher in the long nozzle group (14 cadavers, 100%) compared to short nozzle group (9 cadavers, 64.3%; p = .02). There are fewer specimens that demonstrated deposition of radioactive saline in the vestibule in the long nozzle group (6 cadavers, 42.86%) compared to short nozzle group (13 cadavers, 92.86%; P = .006). Compared to short nozzle group, there are more specimens demonstrating radioactivity in the maxillary, ethmoid, sphenoid, and frontal sinus in the long nozzle group, but the differences were not statistically significant ( p = 0.241, 0.347, 0.126, 0.5). Compared to short nozzle, long nozzle more frequently delivers intranasal drugs beyond the maxillary line and less frequently in the vestibule. These findings support the hypothesis that the use of long and narrow nozzle, instead of the conventional short nozzle, can improve sinonasal drug delivery in post-endoscopic sinus surgery nose.<\/jats:p>","DOI":"10.1177\/0145561319846830","type":"journal-article","created":{"date-parts":[[2019,5,8]],"date-time":"2019-05-08T01:05:06Z","timestamp":1557277506000},"page":"E97-E103","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["Comparison of short nozzle and long nozzle spray in sinonasal drug delivery: a cadaveric study"],"prefix":"10.1177","volume":"98","author":[{"given":"Mustafa","family":"Kapadia","sequence":"first","affiliation":[{"name":"Tarabichi-Stammberger Ear and Sinus Institute Dubai, United Arab Emirates"},{"name":"Department of Otolaryngology, American Hospital Dubai, United Arab Emirates"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Precious Eunice R.","family":"Grullo","sequence":"additional","affiliation":[{"name":"Tarabichi-Stammberger Ear and Sinus Institute Dubai, United Arab Emirates"},{"name":"Department of Otorhinolaryngology, College of Medicine, University of the Philippines - Philippine General Hospital Manila, Philippines"},{"name":"Department of Otorhinolaryngology, Rizal Medical Center, Pasig, Philippines"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Muaaz","family":"Tarabichi","sequence":"additional","affiliation":[{"name":"Tarabichi-Stammberger Ear and Sinus Institute Dubai, United Arab Emirates"},{"name":"Department of Otolaryngology, American Hospital Dubai, United Arab Emirates"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2019,5,7]]},"reference":[{"key":"bibr1-0145561319846830","doi-asserted-by":"publisher","DOI":"10.4193\/Rhino12.000"},{"key":"bibr2-0145561319846830","doi-asserted-by":"publisher","DOI":"10.1016\/j.anai.2014.07.025"},{"key":"bibr3-0145561319846830","doi-asserted-by":"publisher","DOI":"10.1007\/s13346-012-0108-9"},{"key":"bibr4-0145561319846830","doi-asserted-by":"publisher","DOI":"10.1007\/s40136-012-0003-4"},{"key":"bibr5-0145561319846830","doi-asserted-by":"publisher","DOI":"10.1016\/j.otohns.2008.04.020"},{"key":"bibr6-0145561319846830","doi-asserted-by":"publisher","DOI":"10.2500\/ajra.2013.27.3880"},{"key":"bibr7-0145561319846830","doi-asserted-by":"publisher","DOI":"10.1002\/alr.21096"},{"key":"bibr8-0145561319846830","doi-asserted-by":"publisher","DOI":"10.1002\/alr.21172"},{"key":"bibr9-0145561319846830","doi-asserted-by":"publisher","DOI":"10.1067\/mai.2001.115563"},{"key":"bibr10-0145561319846830","doi-asserted-by":"publisher","DOI":"10.2500\/ajra.2013.27.3950"},{"key":"bibr11-0145561319846830","doi-asserted-by":"publisher","DOI":"10.1002\/alr.20072"},{"key":"bibr12-0145561319846830","doi-asserted-by":"publisher","DOI":"10.1002\/lary.24239"},{"key":"bibr13-0145561319846830","doi-asserted-by":"crossref","unstructured":"Pires A, Fortuna A, Alves G, Falc\u00e3o A.
