Background:
A surgical and anatomic approach to the skull base using the transmaxillary route is presented. This route is well-known and used for a long time for sinus conditions.
Method:
This study was performed on injected cadavers. This study describes step by step this approach in microsurgical conditions following a vital lead: the infraorbital nerve.
Results:
Anatomical landmarks are located in order to avoid complications. These complications are on one hand, hemorrhages by vascular lesions and on the other, definitive nerve palsy.
Conclusion:
Several skull base approaches exist, transfacial routes produce cosmetic damages. This route preserves the functional anatomy of the nose because it preserves the integrity of the lateral wall of the nasal cavity.

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...
Overview of the Skull
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...
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,...
