“…20 The anterior part of the middle turbinate is oriented vertically and is attached superiorly to the anterior skull base at the lateral border of the cribriform plate. Posteriorly, the attachment becomes oblique attaching to the lamina papyracea and further posteriorly lies in a coronal plane attaching to the medial wall of the maxillary sinuses (Video 1).…”

“…22,[27][28][29][30] The coronal plane, in particular, is considered as a map for assessing the anatomy that varies significantly even between both sides in the same individual; this may alert about areas of potential complication risk in nasal endoscopic surgery. 18,28,[30][31][32][33][34][35][36][37] …”

The anterior ethmoidal artery (AEA) is an important point for frontal and ethmoid sinuses surgery. CT scans can identify landmarks to help the surgeon find the AEA. Aim: To identify the landmarks of the AEA on the orbital medial wall and on the lateral wall of the olfactory fossa. and to correlate the presence of supraorbital ethmoidal cells with spotting the anterior ethmoidal artery canal. Materials and Methods: Retrospective review of 198 direct coronal paranasal sinuses computed tomography (CT) scans from August to December, 2006. Results: Supraorbital pneumatization was seen in 35% (70 scans). The AEA canal was seen in 41% (81 scans). The anterior ethmoidal sulcus was seen in 98% (194 scans) and the anterior ethmoidal foramen was seen in all the scans (100%). Conclusion: The anterior ethmoidal foramen and the anterior ethmoidal sulcus were anatomical landmarks present in almost 100% of the scans studied. There was a correlation between the presence of supraorbital pneumatization and AEA canal visualization.

“…Computed tomography (CT) has contributed not only to the evaluation of sinonasal diseases, but also to the charac-terization of the paranasal sinuses anatomy (21)(22)(23)(24)(25) . Coronal images can particularly be considered as maps in the evaluation of the anatomy that is highly variable even between the two sides of a same individual, demonstrating areas potentially at risk for complications in the planning of endoscopic nasal surgeries (12,14,17,19,(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32) .…”

OBJETIVO: Avaliar a profundidade das fossas olfatórias e a freqüência de assimetria na altura e na inclinação lateral do contorno do teto etmoidal. MATERIAIS E MÉTODOS: Estudo retrospectivo de 200 tomografias computadorizadas dos seios da face no plano coronal realizadas no período de agosto a dezembro de 2006. As profundidades das fossas olfatórias foram classificadas segundo Keros. O teto etmoidal foi avaliado quanto à simetria entre os lados. RESULTADOS: O tipo de Keros mais encontrado foi o tipo II (73,3%), seguido do tipo I (26,3%) e do tipo III (0,5%). Em 12% (24 exames) havia assimetria entre os lados quanto à altura do teto etmoidal, e em 48,5% (97 exames) observou-se assimetria do contorno do teto, com inclinação lateral da lâmina crivosa de um dos lados. CONCLUSÃO: Em relação à profundidade das fossas olfatórias, o tipo II de Keros foi o mais freqüente. Verificou-se que a assimetria do teto do seio etmoidal, na maioria dos casos, estava relacionada com a inclinação lateral da lamela lateral da lâmina crivosa.
