Abstract

Total surgical decompression of the facial nerve can be offered to patients severely affected by Bell's palsy whether via the transattical or middle fossa approach. We prefer, when feasible, the transattical approach because it does not violate the cranial vault. The purpose of this study was to find the anatomical parameter of the temporal bone, measured by means of computed tomography (CT scan) and to decide which of these approaches should be offered. Sixty temporal bones were studied by CT scan, and then dissected in order to perform total facial nerve decompression via the transattical approach. Correlation between the two studies was established. Results suggest that measurement by CT scan of the attical area in the axial plane (AAA) may determine those patients for whom the transattical approach to facial nerve decompression should be undertaken.
