BackgroundPrecise preoperative radiological evaluation of aural atresia is of utmost importance for surgical planning. Until now, multislice computed tomography (MSCT) has been used but it cannot adequately visualize small structures such as the stapes. Flat-panel volume CT (fpVCT) with its secondary reconstructions (fpVCTSECO) offers a high-resolution visualization of the middle ear. New otosurgical planning software also enables detailed 3D reconstruction of the middle ear anatomy.Aim of the workEvaluation of the use of fpVCTSECO in combination with an otosurgical planning software for a more accurate diagnosis and treatment of congenital aural atresia.Material and methodsSeven patients with congenital aural atresia underwent preoperative MSCT (600 mu m slice thickness) and corresponding fpVCT (466 mu m slice thickness). In addition, fpVCTSECO (99 mu m slice thickness) were reconstructed. The Jahrsdoerfer and Siegert grading scores were determined and their applicability in the abovementioned imaging modalities was evaluated. In addition, the malleus incus complex was analyzed in 3D rendering.ResultsImaging with fpVCTSECO enabled reliable visualization of the abnormalities, in particular the ossicular chain. A significant difference in the Siegert grading score was found. In addition, the malleus-incus complex could be visualized better in 3D.DiscussionThe introduction of new imaging techniques and surgical planning techniques into the diagnostic concept of aural atresia facilitates the identification of malformed anatomy and enables systematic analysis. This combination can also help to more accurately classify the pathology and thus increase the safety and success of the surgical procedure. HintergrundEine pr & auml;zise pr & auml;operative radiologische Evaluation von Auralatresien ist f & uuml;r die Operationsplanung von gr & ouml;ss ter Bedeutung. Bisher wurde hierf & uuml;r die Multislice-Computertomographie (MSCT) verwendet, die jedoch kleine Strukturen wie den Stapes nur unzureichend dargestellen kann. Die ,,flat-panel volume CT" (fpVCT) mit ihren sekund & auml;ren Rekonstruktionen (fpVCTSECO) bietet eine hochaufl & ouml;sende Darstellung des Mittelohrs. Eine neue otochirurgische Planungssoftware erm & ouml;glicht & uuml;berdies die detaillierte 3-D-Rekonstruktion der Mittelohranatomie.Ziel der ArbeitEvaluierung des Einsatzes von fpVCTSECO in Kombination mit einer otochirurgischen Planungssoftware zur genaueren Diagnose und Behandlung kongenitaler Auralatresien.Material und MethodenSieben Patienten mit kongenitaler Auralatresie erhielten pr & auml;operativ ein MSCT (600 mu m Schichtdicke) und ein korrespondierendes fpVCT (466 mu m Schichtdicke). Zus & auml;tzlich wurden fpVCTSECO (99 mu m Schichtdicke) rekonstruiert. Die Jahrsdoerfer- und Siegert-Grading-Scores wurden bestimmt und ihre Anwendbarkeit in den oben genannten bildgebenden Modalit & auml;ten bewertet. Zus & auml;tzlich wurde der Malleus-incus-Komplex im 3-D-Rendering analysiert.ErgebnisseDie Bildgebung mit fpVCTSECO erm & ouml;glichte eine zuverl & auml;ssige Darstellung der Anomalien, insbesondere der Geh & ouml;rkn & ouml;chelchenkette. Es wurde ein signifikanter Unterschied im Siegert-Grading-Score festgestellt. Zus & auml;tzlich konnte der Malleus-Incus-Komplex in 3-D besser dargestellt werden.DiskussionDie Einf & uuml;hrung neuer bildgebender Verfahren und chirurgischer Planungstechniken in das diagnostische Konzept der Auralatresie erleichtert die Identifizierung der fehlgebildeten Anatomie und erm & ouml;glicht eine systematische Analyse. Diese Kombination kann auch dazu beitragen, die Pathologie genauer zu klassifizieren und damit die Sicherheit und den Erfolg des chirurgischen Eingriffs zu erh & ouml;hen.
