CT scans of the head performed at the Small Animal Teaching Hospital, University of Liverpool, between April 2007 and March 2009 for dogs diagnosed with aspergillosis (group 1) and unaffected dogs of similar breeds (group 2) were selected for study. Sinus depth was measured at four standardised locations from reconstructed images of these CT scans. Data were compared for differences in sinus depth between groups and between landmarks. No significant difference was found between measurements within individual dogs or for each of the various landmarks between groups. Difference in depth of the sinuses between landmarks was significant (P&lt;0.001). Sinus depth was significantly greater at the more caudal landmarks and was shallowest at the previously recommended landmark for sinus entry. In 54 per cent of dogs, the frontal sinus depth measured less than or equal to 2\u00a0cm at one or more of the landmarks. Sinus entry at the deepest point will reduce the risk of accidentally damaging underlying structures. This may be approximately 1\u00a0cm caudal, in breeds of dog that typically develop aspergillosis, to a previously suggested landmark.<\/jats:p>","DOI":"10.1136\/vr.100041","type":"journal-article","created":{"date-parts":[[2011,10,20]],"date-time":"2011-10-20T22:49:37Z","timestamp":1319150977000},"page":"20-20","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":11,"title":["Frontal sinus depth at four landmarks in breeds of dog typically affected by sinonasal aspergillosis"],"prefix":"10.1002","volume":"170","author":[{"given":"R.","family":"Burrow","sequence":"first","affiliation":[{"name":"Small Animal Teaching Hospital University of Liverpool, Leahurst Neston Cheshire CH64 7TE UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.","family":"McCarroll","sequence":"additional","affiliation":[{"name":"Institute for Cardiovascular and Medical Sciences Glasgow Cardiovascular Research Centre 126 University Place Glasgow G12 8TA UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Baker","sequence":"additional","affiliation":[{"name":"Small Animal Teaching Hospital University of Liverpool, Leahurst Neston Cheshire CH64 7TE UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P.","family":"Darby","sequence":"additional","affiliation":[{"name":"Department of Civil and Building Engineering Loughborough University Loughborough Leicestershire LE11 3TU UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F.","family":"McConnell","sequence":"additional","affiliation":[{"name":"Small Animal Teaching Hospital University of Liverpool, Leahurst Neston Cheshire CH64 7TE UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P.","family":"Cripps","sequence":"additional","affiliation":[{"name":"Department of Epidemiology and Population Health Institute of Infection and Global Health Faculty of Health and Life Sciences University of Liverpool Leahust Neston Cheshire CH64 7TE UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,1,7]]},"reference":[{"key":"e_1_2_5_2_1","first-page":"328","article-title":"Treatment and immunological evaluation of three cases of canine aspergillosis","volume":"13","author":"Barrett R.
