title: Bilateral temporal spinous projections overshadowing the sphenoidal spines: an anatomical and radiological evaluation.
abstract: The infratemporal fossa has traditionally been described as a post-maxillary space, which is open below, to the rear and laterally. The most reliable osseous landmarks of the infratemporal and parapharyngeal spaces are the pterygoid and styloid processes and the sphenoidal spine. In the present study the skull exhibited the normal sphenoidal spines along with a prominent spinous projection emanating bilaterally from the tympanic plate of the temporal bone. The objective of the present paper is to report an anatomical and radiological evaluation of the sphenoidal spines coexistent with bilateral temporal spinous projections. Additionally, the topographical relationship of this osseous variation is discussed with particular reference to neurovascular structures. Unduly prominent temporal spinous projections may cause obstruction, thus reducing the operative field. The anatomical variations relating to bony and vascular structures in this region are of paramount importance to neurosurgeons and otorhinolaryngologists.
