Abstract
121 patients (124 ears) of sudden deafness in last 6 years are presented.
63 patients were given medical treatment (Group SGB-) and 58 patients were treated with stellate ganglion block and drugs (Group SGB+).
83.9% of all the cases showed more than 10-dB average pure tone gain, and the difference between the two groups is not significant.
More significantly, in the cases of high hearing loss more than 61dB 89.5% in Group SGB+ showed over 10dB improvement, compared to 75.9% in Group SGB-, and in the cases of high hearing loss with vestibular signs 82.4% in Group SGB+ revealed over 10dB impairement, compared to 40% in Group SGB-.
The results are also observed in relation to the factors associated with prognosis of sudden deafness.
