Abstract:
Aneurysmal bone cyst (ABC) is an uncommon benign lesion that rarely presents in the craniofacial region. Aneurysmal bone cysts represent nearly 1.4% of all bone tumors, and among those, only 3% are located in the cranium. In this study, we report on an ABC located in the sphenoid bone with superior nasal cavity and ethmoid extension. The presenting symptom of our patient was headache, followed by diplopia, loss of visual accuracy, and abduction restriction. We successfully resected the lesion by a combined subcranial-midfacial degloving approach without any complications or recurrence.

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...
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...

Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...
