[Study on stepwise regression of risk factors in patients with sudden deafness].
OBJECTIVE
To explore the affected factors of sudden deafness.


METHODS
To analyse the stepwise regression of various factors in age, systolic pressure/diastolic pressure, immunoglobulin G, A, M, KPTT, PT, Fbg, FDP, ELT and auditory threshold.


RESULTS
There was significant correlation (positive straightline relativity) between the auditory threshold and KPTT in patients with sudden hearing loss, and between the auditory threshold and PT in the analysis of coagulogram.


CONCLUSIONS
The state of blood circulation didn't show hypercoagulability in some patients with sudden hearing loss. We must be very careful in therapy of anticoagulation and the increment of blood volume.
