Statistical Analysis
SPSS 22.0 software was used for data analysis, and data conforming to normal distribution were expressed as mean ± standard deviation. Paired sample T test was used to analyze the difference in the signal intensity of the IAC between the affected and unaffected sides. Pearson correlation was utilized to examine the association between low, middle, and high tone hearing thresholds, cochlear and vestibular hydrops, as well as signal intensity of the IAC on the affected side. A statistical difference was observed when P<0.05.
