Design: The parietal morphology of the PSC has 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 PSC, taking some previously notified, standardised measurements of normality as reference. Results: 318 patients have been analysed (604 petrous bone) by CT and we have distinguished five different radiological patterns: type or normal, thick, thin, pneumatised and dehiscent. The first three patterns, normal, thick and thin, have in common the existence of a compact bone interposed between PSC and posterior fossa, being in the normal pattern has a thickness of between 0.9 and 2.5 mm (327 cases, 54.13 %), in the thick pattern is ≥2.6 mm (99 cases, 16.39 %) and in the thin pattern is ≤1.2 mm (158 cases, 26.15 %). The fourth pattern, pneumatised, is characterised by having retro labyrinthine cells between PSC and media fossa (19 cases, 3.14 %). Finally, a dehiscent pattern was observed in 2 cases (0.3 %). Conclusion: We describe five different radiological patterns: type or normal, thick, thin, pneumatised and dehiscent. The thin type (<0.5 mm or 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. 000149989 540__ $$9info:eu-repo/semantics/closedAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000149989 590__ $$a1.047$$b2014 000149989 591__ $$aSURGERY$$b135 / 196 = 0.689$$c2014$$dQ3$$eT3 000149989 591__ $$aANATOMY & MORPHOLOGY$$b16 / 21 = 0.762$$c2014$$dQ4$$eT3 000149989 591__ $$aRADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING$$b102 / 124 = 0.823$$c2014$$dQ4$$eT3 000149989 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000149989 700__ $$0(orcid)0000-0001-9372-4267$$aWhyte, J.$$uUniversidad de Zaragoza 000149989 700__ $$aMartínez, C. 000149989 700__ $$aGracia-Tello, B. 000149989 700__ $$0(orcid)0000-0002-4263-4023$$aWhyte, A.$$uUniversidad de Zaragoza 000149989 700__ $$0(orcid)0000-0002-2068-3617$$aObón, J.$$uUniversidad de Zaragoza 000149989 700__ $$aCrovetto, R. 000149989 700__ $$aCrovetto, M.A. 000149989 7102_ $$11003$$2027$$aUniversidad de Zaragoza$$bDpto.
