Radiography: skull (basic)

Contributor(s): Patsy Whelehan

Introduction

  • Radiography of the skull requires general anesthesia. This is the only way to obtain accurate projections.
  • A grid is not necessary.
  • Radiography of the skull for fractures may be of questionable value as the presence of a fracture is considerably less significant than the presence of neurological signs. It may, however, in some cases, be of value in explaining the reason for the signs when trauma is a possibility but has not been observed.
  • When using non-screen film for intraoral radiography the increase in exposure required is immense. It is therefore necessary to ensure that the equipment is adequate, that the finger is not removed from the exposure button before completion of the exposure, and, most importantly, that staff do not re-enter the room before termination of the long exposure.
  • The objective is to produce well-positioned radiographs which are correctly exposed and developed, free from movement blur and free from artifact.
  • The anatomical marker, the patient's identification, the date, and the name of the hospital or practice should be clearly shown.

Uses

  • Soft tissue neoplasia, eg nasal tumors Skull: nasal neoplasia - intra-oral radiograph LSA pre-treatment .
  • Bulla disease
  • Temporomandibular joint disease.
  • Fracture.
  • Bony neoplasia Skull: mandibular tumor - radiograph lateral oblique  Skull: mandibular tumor - radiograph DV .
  • Hydrocephalus.
  • Nasal foreign body.
  • External ear disease Skull: middle ear disease - radiograph DV .

Advantages

  • Non-invasive (although may require GA).
