They could identify several key structures such as incudomalleolar articulation, tympanic segment of the facial nerve, lateral semicircular canal and aditus ad antrum, all without provoking lesions in the middle ear structures.
We present a case of facial nerve palsy concurrent with a benign cystic lesion of the temporal bone, adjacent to the tympanic segment of the facial nerve.
A 5 x 5-mm cystic lesion was noted in the anterior epitympanic space abutting on the tympanic segment of the facial nerve.
However, the tympanic segment of the facial nerve was focally pressed at the anterior epitympanum by the air cells, which were filled with yellowish fluid.
High-resolution computed tomography (CT) of the temporal bones showed significant ossicular displacement; no evidence of a fracture or penetrating bony spicule involving the tympanic segment of the facial nerve was found (figure).
1-3) Direct trauma from the earring itself or displacement of the incus into the tympanic segment of the facial nerve likely led to the development of edema and subsequent delayed-onset paralysis.
Additionally, the geniculate ganglion and tympanic segment of the facial nerve also had greater contrast uptake than the opposite side, indicating tumor in these sections.
A 2 x 2-mm mucosa-like mass was encountered in the region of the tympanic segment of the facial nerve superior to the stapes (figure).
They include the absence of the foramen spinosum on the affected side and the enlargement of the proximal tympanic segment of the facial nerve canal adjacent to the cochleariform process.
The next step was to reach the geniculate ganglion by following the tympanic segment of the facial nerve.
To avoid the difficulties encountered with other techniques, we use the cochleariform process in the middle ear as the primary landmark for identifying the tympanic segment of the facial nerve.
The tympanic segment of the facial nerve could be seen just above the oval window.
