Quantitative Olfactometry in the Measurement of Posttraumatic Hyposmia: A Simple Method

Abstract

Abstract THE SENSE of smell is usually measured qualitatively by asking the patient to identify an easily recognizable substance by sniffing. In this test, memory, association, and intelligence all play a role.1 Furthermore, hyposmia, or a decreased sense of smell, cannot be measured in this way. Attempts at quantitative, clinical olfactometry2-4 have generally been discarded as inaccurate, cumbersome, or too time consuming for office use. However, in 1923, the distinguished rhinologist, Dr. Arthur Proetz described a simple, accurate, clinical method of quantitative olfactometry.5 Posttraumatic anosmia has been measured by various investigators.6-8 Leigh measured 7.2%9 and Sumner 7.5%10 of anosmia after head injury. Furthermore, the incidence of anosmia is reported to increase with the severity of the head trauma. There have been very few studies, however, of posttraumatic hyposmia. This study proposes to reproduce the results obtained by Proetz and apply his method to the measurement References 1.
