In attempting to outline the clinical evaluation of these patients with vertigo we have discussed examples which range in order from benign self-limited disease to those requiring emergency surgery or extensive diagnostic evaluation. We sought also to illustrate how the logic of hypothesis testing is generally employed by clinicians in approaching this or other diagnostic problems. The examples were chosen to illustrate the indications for, as well as the limitations of, the various diagnostic modalities--caloric testing, electronystagmography, audiometric testing, roentgenographic and nuclear medicine procedures--which may be employed by the clinician. Most of the skills discussed in our paper, though traditionally accorded to the fields of neurology and otolaryngology, would seem to be fundamental for any general physician, while the problem of vertigo is an example of how common ambulatory problems may require knowledgeable approach to sort self-limited from more serious illnesses as well as to utilize procedures with purpose and efficiency. |
