Abstract:
Post-traumatic facial palsies are generally observed after a transverse, longitudinal or comminuted fracture of the pars petrosa. Occasionally, the fracture does not involve the Fallopian aqueduct and another mechanism must be sought. The authors present a case of facial palsy that occurred after a Le Fort's fracture of the base of the skull, not involving the Fallopian aqueduct on the CT scan. This was confirmed by surgical exploration. The authors recall the possibility of a facial palsy through the stretching of the nerve by the petrosal nerve.

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
