Abstract:
The nasal cavity and sinuses may be exposed primarily via a dorsal or ventral surgical approach. Surgical planning involves the use of advanced imaging, such as computed tomography or MRI. Surgical treatment of lesions of the nasal cavity usually is limited to benign lesions or can also be used in combination with adjunctive therapy, such as radiation therapy. Extreme caution must be exercised with a dorsal approach to the nasal cavity to avoid complications of inadvertent penetration into the brain case. Gentle tissue handling and careful closure of the mucoperiosteum must be exercised following a ventral approach to minimize the risk of oronasal fistula formation.

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...
