THE METHOD OF VENOUS OLFAOTCRY TEST ESPECIALLY ON ITS APPLICATION

On 119 cases which complained chiefly of the oflactory disturbance, venous olfactory test was performed.The results were as follows:(1) According to previous olfactcry test, dysosmia was classified into two groups, i. e., hyposmia and anosmia. Each of which, according to that test, is classified into two subgroups, thus dysosmia is classified into four groups, from I-degree to IV-degree.(2) According to the region of disturbance of sence of smell olfactory disturbance is divided into three types;(1) morphorgenic type(2) neurogenic type(3) combined typeThen a clinical study of signification of each of them was performed.(3) We stated that there were three types in the process of healing of dysosmia and the careful study of the healing process was helpful to evaluate the prognosis.

THE METHOD OF VENOUS OLFACTORY TEST

1) Initial and terminal time of sense of smell surveyed by venous injection of Alinamine (Vitamine B1 preparate) were the following;(a) Normal in health : 9.3sec, 170sec Hyposmia: 11.1sec, 60.5sec so-called Anosmia: 13.9sec, 48sec(the former: initial time, The latter: terminal time)(b) The longer terminal time was the more sensitive olfactory mucous membrane.2) In 15 cases with chronic sinuitis, we performed the venous olfactory test at a week and a month before and after its operation.The results were followed; sense of smell had the tendency to improve a month postoperatively and only in patients whose mucous membranes of paranasal cavities were fibrous, and naaal findiugs improved corresponding with the result of its test.At last, we stated that in 10cases of datients with deviations of the septum sense of smell improved only in r, ght indication of the operation.

METHODS OF THE SMELL TEST

1) As the results of several examinations, we made the olfactorymeter almost satisfied various conditions, which made the basis inventing the smell tests.2) The smell tests were divided in three; pressure, dilution and venous olfactoiy test. Principle, apparatus and method of each of these tests were stated.3) From the results os these examinations, we could know of ihe olfactory disturbance dependent upon in nasal forms by pressure test and upon sensibility of olfactory mucous membrane by dilution test. venous olfactory test could survey for patients compelelty lost of nasal olfactory sense.

STUDIES ON OLFACTORY SENSE

L.We surveyed Minimal Identificial Odor (M.I.O.) and made olfactogram on 37 cases with nasal disorders. In cases with no nasal disorders the olfactograms showed strait-horizontal lines, but in the abnormal cases they showed different lines which were divided into four types.According to the studies the significant relations were discovered between the olfactograms and intranasal constructures. 2.M I.O.and olfactogram were in proportion to the grade of nasal signes, nasal disorders and objective olfactory sense. 3.Statistic reviews with regard to intranasal constructures, nasal signes and nasal disorders were performed on twenty one cases with so-called anosmy which could not be surveyed by means of olfactometer. 4.M.I.O.was surveyed on 3 cases of chronic sinusitis and on 3 cases of tonsillitis pre-and postoperatively, and this method was proved to be beneficial to observe the effectiveness of the operations on the olfactory sense.
