The goal of this multicenter, prospective, randomized controlled trial is to evaluate the efficacy and safety of acupuncture combined with corticosteroid therapy in treating sudden sensorineural hearing loss (SSNHL). The main questions it aims to answer are:
Does acupuncture combined with corticosteroids improve hearing recovery (pure tone audiometry, PTA) at 8 weeks compared with sham acupuncture combined with corticosteroids? Does this treatment improve secondary outcomes, including tinnitus, dizziness, sleep quality, anxiety, and quality of life? Researchers will compare acupuncture (experimental group) with sham acupuncture (control group) to determine the added therapeutic effect of acupuncture.
Participants will:
1. Receive either real acupuncture or sham acupuncture 3 times per week for 4 weeks.
2. Meanwhile, take oral prednisone (1 mg/kg/day, maximum 60 mg/day) for 7 days followed by a 7-day taper.
3. Undergo hearing tests (PTA, word recognition scores), vestibular function tests, and complete validated questionnaires (SF-36, HADS, ISI, DHI, THI, and TCM symptom scales) at baseline and weeks 1, 2, 4, 8, and 12.
4. Receive salvage intratympanic steroid injections if hearing does not improve sufficiently by day 14.
