Double skull base defects with primary spontaneous cerebrospinal fluid leaks in a single patient: temporal and
Abstract:
Primary spontaneous cerebrospinal fluid leaks occurring in the absence of any apparent cause are rare. Patients may present such leaks simultaneously, or successively, in multiple locations. We report here the sixth case of anterior and lateral skull base defects presented in a single patient. Although rhinoliquorrhea and otoliquorrhea were reported separately in the literature, we postulated that the pathophysiology is the same for the whole skull base; obesity seems to contribute to the development of such primary spontaneous cerebrospinal fluid leak. Consequently, management is similar and regular follow-up is very important.

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...
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,...
Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
