Several types of burs have been invented to ablate strong bone in the frontal sinus access but nevertheless surgical results seem to differ significantly. The benefits and shortcomings of different burs are subjected to a comparative evaluation.<\/jats:p><\/jats:sec><jats:sec><jats:title>STUDY DESIGN<\/jats:title><jats:p>Five cadaver specimens were duplicated by means of dental molding and casting techniques to provide identical microanatomy for comparative studies on frontal sinusotomy. Different burs (conventional straight bur, right\u2010angled bur according to Blokmanis, and curved frontal sinusbur) were applied to create a type IIb frontal sinusotomy according to Draf in microanatomical replicas. The geometry of the frontonasal neoostium was measured and its dimensions were contrasted to the collateral damage. Bone ablation was calculated by repeated weighting and the area of damaged mucosa was quantified using a 3D analyzing system.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>A frontal sinus neoostium measuring 9 \u00d7 10\u00a0mm on average was created by type IIb frontal sinusotomy according to Draf. The complementary use of an angled bur showed some specific improvements that applied best to spacious anatomic specimens. Those specimens subjected to an extensive use of the straight drill revealed significant collateral damage forming a contrast to minor enlargement of the neoostium. The curved frontal sinus bur showed considerable technical insufficiencies.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>Judicious use of the straight drill is recommended for those rare cases of therapy\u2010resistant frontal sinusitis treated by an extended type of frontal sinusotomy. New technical refinements of the curved frontal sinus burs should be subjected to repeated evaluation.<\/jats:p><\/jats:sec>","DOI":"10.1016\/j.otohns.2004.02.016","type":"journal-article","created":{"date-parts":[[2004,9,14]],"date-time":"2004-09-14T17:03:33Z","timestamp":1095181413000},"page":"187-191","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Experimental Evaluation of Drills for Extended Frontal Sinusotomy"],"prefix":"10.1002","volume":"131","author":[{"given":"Werner","family":"Hosemann","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology, Head and Neck Surgery University of Greifswald Greifswald Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniela","family":"Herzog","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology University of Regensburg Regensburg Germany"},{"name":"The Department for Lasertechnology in Medicine University of Ulm Ulm Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Achim G.","family":"Beule","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Head and Neck Surgery University of Greifswald Greifswald Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Holger","family":"Kaftan","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Head and Neck Surgery University of Greifswald Greifswald Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2016,5,17]]},"reference":[{"volume-title":"Minimally invasive endonasal sinus surgery.","year":"2000","author":"Hosemann W","key":"e_1_2_6_2_1"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-199511000-00004"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1177\/000348949410301205"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1043-1810(10)80087-9"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1043-1810(06)80011-4"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1067\/mhn.2001.116186"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200001000-00030"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-199002000-00010"},{"key":"e_1_2_6_10_1","first-page":"885","article-title":"Modified Lynch procedure for chronic frontal sinus disease: Rationale, technique, and long\u2010term results","volume":"99","author":"Neel HB","year":"1989","journal-title":"Laryngoscope"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1043-1810(06)80012-6"},{"key":"e_1_2_6_12_1","first-page":"1369","article-title":"Externe oder interne Operation der Nebenho\u00f6hleneiterungen [External vs. internal surgical access for paranasal sinusitis]","volume":"43","author":"Halle M","year":"1906","journal-title":"Berl Klin Wochenschr"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.2500\/105065897781446784"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1007\/s001060050045"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-002-0534-2"}],"container-title":["Otolaryngology\u2013Head and Neck Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1016\/j.otohns.2004.02.016","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1016\/j.otohns.2004.02.016","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/aao-hnsfjournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1016\/j.otohns.2004.02.016","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,20]],"date-time":"2025-10-20T12:07:39Z","timestamp":1760962059000},"score":1,"resource":{"primary":{"URL":"https:\/\/aao-hnsfjournals.onlinelibrary.wiley.com\/doi\/10.1016\/j.otohns.2004.02.016"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2004,9]]},"references-count":14,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2004,9]]}},"alternative-id":["10.1016\/j.otohns.2004.02.016"],"URL":"https:\/\/doi.org\/10.1016\/j.otohns.2004.02.016","archive":["Portico"],"relation":{},"ISSN":["0194-5998","1097-6817"],"issn-type":[{"type":"print","value":"0194-5998"},{"type":"electronic","value":"1097-6817"}],"subject":[],"published":{"date-parts":[[2004,9]]},"assertion":[{"value":"2016-05-17","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
