In the treatment of sudden deafness (sensorineural hearing loss) patient, the purpose of stellate ganglion block is the vasodilation of inner ear and the stellate ganglion block is combined with the medical treatment usually. We used the long acting local anesthetics to extend this effect of the stellate ganglion block. In the cases of 5 patients (male 3, female 2) of sudden deafness, we carried out stellate ganglion block daily in each patient and used 15 ml of 0.5% lidocaine, 0.125% bupivacaine or 0.125% tetracaine mixed with 0.1 mg epinephrine (1:150,000) alternately. Total frequencies of stellate ganglion block in each patient were 28, 15, 11, 8, 7 times, respectively. Duration of stellate ganglion block was 145.8+/-19.22 minutes in lidocaine, 230.9+/-32.28 minutes in bupivacaine (1.58 times than lidocaine), 267.4+/-36.60 minutes in tetracaine (1.83 times than lidocaine), but there was no statistically significant difference between the duration of bupivacaine and tetracaine (p>0.1). Effects of stellate ganglion block with medical treatment (nicotinic acid, thiamine, and ATP(R)) in 5 sudden deafness patients were as follow: two cases had complete recovery, two cases had a partial improvement and one case had no response. |
