Effect of stellate ganglion injections guided by different approaches on hearing threshold in patients with sudden deafness

Abstract Objective The current study was conducted aimed at investigating the effect of stellate ganglion injection guided with different approaches on hearing threshold in patients harboring sudden deafness. Methods There involved a total of 68 patients with sudden deafness in our study. The patients were randomly allocated into control group and study group, with 34 cases in each group. The control group and study group were respectively given conventional blind puncture block and ultrasound-guided stellate ganglion injection. The clinical efficacy, first puncture success rate, first block success rate, average block time, hearing threshold improvement value, vertigo disappearance time, hearing recovery time, hemorheological changes and complications of the two groups were compared. Results The total effective rate of the study group was significantly higher than that of the control group (96.06 vs. 76.47%, P   0.05). After treatment, however, the levels of EAI, HCT and PV in the two groups were lower. Furthermore, the levels of EAI, HCT and PV in the study group were significantly lower compared with the control group (P  Conclusion Ultrasound-guided stellate ganglion injection achieved beneficial effects in treating sudden deafness, which is available for wide clinical practice.
