Universidad de Zaragoza (orcid)0000-0002-5494-343X Radiological patterns of the bony roof of the superior semicircular canal 2013 Objectives: To study the radiological patterns of the bony roof of the superior semicircular canal with a view for obtaining readily applicable conclusions. Design: 84 patients (163 petrous bones) have been studied by Multi-slice Helical Computed tomography (Philips Brilliance 6). We have determined the distribution of the different types of bone cover of the superior semicircular canal, taking some previously notified, standardised measurements of normality as reference. Results: During the analysis of the roof of the superior semicircular canal, we have distinguished five different types, depending on their thickness and tomodensitometric aspect. Normal pattern in 121 cases (74.2 %), with a thickness of between 0.6 and 1.7 mm, papyraceous pattern or fine thickness ≤0.5 mm that appears in 23 of our cases (14.1 %), thick pattern ≥1.8 mm that we have observed in 11 cases (6.7 %), and pneumatised pattern in 5 cases (3.1 %), which is characterised by having supralabyerinthine cells. Finally, a dehiscent pattern was observed in three cases (1.8 %). Conclusion: We describe five patterns of superior semicircular canal roofs: normal, thick, papyraceous, pneumatised and dehiscent. The papyraceous type and the dehiscent type would be subject to producing pathology, and in some cases the latter could be a consequence of the former. info:eu-repo/semantics/closedAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 1.333 2013 ANATOMY & MORPHOLOGY 11 / 20 = 0.55 2013 Q3 T2 SURGERY 108 / 199 = 0.543 2013 Q3 T2 RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING 81 / 122 = 0.664 2013 Q3 T3 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Whyte, J.
