Skull radiography is the radiological investigation of the skull vault and associated bony structures. Seldom requested in modern medicine, plain radiography of the skull is often the last resort in trauma imaging in the absence of a CT. Indications Skull radiographs are indicated for a variety of settings including: trauma This examination is able to assess for medial and lateral displacements of skull fractures, in addition to neoplastic changes and Paget disease.

The skull (TA: cranium) consists of 22 bones, excluding the three ossicles in each middle ear. All of the bones of the skull, except for the mandible, are connected to each other by sutures (fibrous joints) and are thus immobile. These 21 bones form the cranium, and are further subdivided into: neurocranium. calvaria; skull base (basicranium) Skull X-ray is not indicated for identification of skull fractures CT is usually required if there is history of sufficient trauma to cause a fracture Specific X-ray views are required to look for foreign bodies in the scalp Skull. The skull rests on the superior aspect of the vertebral column. It is composed of 22 separate bones divided into two distinct groups: 8 cranial bones and 14 facial bones. The cranial bones are divided further into the calvaria and floor ( Box 20-1 ). The cranial bones form a protective housing for the brain. What is a skull X-ray? X-rays use invisible electromagnetic energy beams to make images of the skull. Standard X-rays are done for many reasons, including diagnosing tumors, infection, foreign bodies, or bone injuries. X-rays use external radiation to produce images of the body, its organs, and other internal structures to diagnose a problem.

The skull is the skeletal framework of the head of vertebrates formed by the cranium. It encompasses the frontal, parietal, occipital, temporal, zygomatic, lacrimal, nasal, ethmoid, and sphenoid bone as well as the maxilla. This chapter illustrates the normal CT anatomy of the skull. Keywords Jaw Normal anatomy Download reference work entry PDF Introduction The skull is a compact structure that covers and protects the brain and facial organs. [1] [2] It is in a complex anatomical relationship with many craniofacial organs and associated tissues, each of which has a different embryological origin and performs different functions.

X-rays use a small amount of radiation beams to make images. Standard X-rays are done for many reasons. They are done to diagnose tumors, infection, foreign bodies, or bone injuries. X-ray beams pass through body tissues onto treated plates. The more solid a structure is, the whiter it appears on the film.

A skull x-ray is a picture of the bones surrounding the brain, including the facial bones, the nose, and the sinuses. How the Test is Performed You lie on the x-ray table or sit in a chair. Your head may be placed in different positions. How to Prepare for the Test Tell the health care provider if you are pregnant or think you are pregnant.

The skull is a solid bony structure that encloses and protects the brain and other components of the central nervous system. It consists of 8 cranial bones and 14 facial bones (see our article on radiographic positioning of the face and mandible ). The back of the cranium consists of the occipital and right and left parietal bones. 1. Normal Skull Anatomy. Recognizing Symmetry: Normal Cranial Features showcase a balanced appearance of cranial bones. Clear Delineation: The skull base and vault should be distinctly outlined. Expected Contours: Familiarize with the typical contours of facial bones. 2. Fractures and Trauma Indicators. Cracks and Signs of Impact: Identify linear or depressed fractures and signs of impact.
