Computed tomography of the parapharyngeal space.
The parapharyngeal space is a potential anatomic space of appreciable clinical importance which, because of its location deep within the neck, has historically been difficult to evaluate by physical examination and conventional imaging methods. Computed tomography has provided an important and accurate means of noninvasively defining both the anatomy and pathology of this area. This discussion will initially pertain to the normal anatomy and anatomical relationships of the parapharyngeal space. Traditional methods of imaging will be briefly reviewed but emphasis will be on CT and the most appropriate means of utilization of CT. The more important pathology will be included in order to illustrate the advantages of current imaging techniques.
