Objectives
This study was conducted to evaluate the effectiveness of Chuna manual therapy (CMT) on hearing recovery in patients with sudden deafness (SD).
Methods
We conducted a comprehensive search for randomized controlled trials (RCTs) that applied CMT for SD through MEDLINE, CENTRAL, EMBASE, CNKI, KMbase, OASIS, ScienceOn, and RISS up to March 31, 2025. The risk of bias in the included studies was assessed using the Cochrane Handbook's Risk of Bias 2.0 tool, and statistical analyses of the extracted data were performed using Review Manager (RevMan) version 5.4.
Results
Among the 9 RCTs that were finally selected, meta-analyses were conducted on 8 RCTs that reported total effective rate (TER) based on pure tone audiometry (PTA) and on 3 RCTs that reported PTA outcomes. The results showed that CMT combined with western medicine (WM) showed significant higher complete recovery compared to WM alone, with a relative risk (RR) 1.83 (95% confidence interval (CI), 1.24 to 2.69; p < 0.005) and PTA decrease Mean difference (MD) -5.82 (95%, CI, -10.29 to -1.35). Also, CMT and acupuncture combined with WM showed significant higher complete recovery compared to WM alone, with RR 3.02 (95% CI, 1.58–5.77; p < 0.005) and PTA decrease MD -6.66(95% CI, -9.58 to -3.73).
Conclusions
CMT, when combined with WM, showed a significant effect on hearing recovery in patients with SD, suggesting that it could be considered as a treatment option in combination therapy. However, as the included studies were of low quality, there is a need to establish stronger evidence through well-designed, high-quality RCTs.
