“…[7] This report discussed observations of classical autoradiological planes using proper patient positioning techniques in direct CT. [6,7] Autoradiological planes used with direct CT include transverse (Hirtz), coronal, sagittal, semiaxial (Guillen), semilongitudinal (Zonneveld), axiopetrosal (Pöschl), and longitudinal (Stenvers). [6][7][8][9][10][11][12] To achieve these planes using CT, the device was surrounded by a plate that rotates the patient through the sectional plane centre around the vertical axis.…”

“…[6,7,9,10] This plane is ideal for basic assessment of temporal bones, since it provides the patient with comfort and enables comparison of the bilateral petrous bone in a single plane. [6,7,9,10] When a single-sectional plane is used, the structures parallel to the sectional plane are partially visible or absent. Therefore, temporal bone CT imaging requires at least two positions.…”

Anatomic basis of the infratemporal approach of the jugular foramen

A description of the lateral infratemporal approach of the jugular foramen (JF) was performed according to bone data, anatomico-radiologic relationships and microsurgical and endoscopic dissection: the jugular foramen is an anteromedial fissure of the petro-occipital fissure. The location of the exocranial facial nerve and the skeletonization of the third portion of the facial canal represents the main obstacle. A retro-facial dissection, then a medio-facial sub-labyrinthine dissection, while displacing the sigmoid sinus, should avoid a systematic diversion of the nerve, which is the cause of severe paralysis. The broad approach of the "pars nervosa" of the jugular foramen demands the control of the vertical part of the carotid canal. The lateral infratemporal approach of the jugular foramen is necessary for the treatment of specific lesions of the area (chemodectoma, neurinoma), which is invaded contiguously (carcinoma).

The aim of this study was to define the imaging of the retrotympanum precisely by means of high-resolution CT. Based on 66 scans of petrous bones performed in 49 patients observed in an otologic department, several retrotympanic structures were studied: the pyramidal eminence, ponticulus, subiculum, chordal ridge, tympanic sinus of Proctor, sinus tympani and recess of the facial n. The variations in morphology and depth were noted as well as the relationship between the pyramid and the facial canal. In a second phase the same anatomic structures were studied in 24 temporal bones removed from embalmed cadavers and investigated with the same radiologic technique. Anatomic correlations were made for six temporal bones to confirm the general applicability of our radiologic hypotheses. In CT the pyramidal eminence was visualised in 100% of cases, the chordal ridge in 52%, the ponticulus in 63% and the subiculum in 57%. As regards the different recesses, the sinus tympani was visualised in 95% of cases, the posterior tympanic sinus of Proctor in 38%, the fossula of Grivot in 47% and the facial recess in 80%. The mean depth of the sinus tympani was 2.7 mm and that of the tympanic sinus of Proctor was 1.65 mm; the fossula of Grivot was assessed as 2.1 mm and the facial recess as 2.2 mm. A better knowledge of these sinuses and their variations will aid the surgeon, particularly in a posterior tympanotomy or a retro-facial approach.
