Multicenter Registry Update
This update highlights cases where hyperbaric oxygen treatment was used for Idiopathic Sudden Sensorineural Hearing Loss (ISSNHL). The Registry has accumulated a substantial number of cases, and we are beginning a comprehensive data analysis.
Here is just a brief overview:
- Total number of cases entered = 556; 256 with complete pre-and post-treatment pure tone average data
- Mean improvement in Pure-Tone Average (PTA) was 14 dB (p<0.0001)
- The mean percentage of Word Recognition improved significantly
- Mean Quality of Life measures increased moderately
- Patient satisfaction with treatment was generally positive, but long-term follow-up results will require more in-depth analysis.
Graphs corresponding to the above bullet points follow below.
Although ISSNHL is a UHMS-approved indication for Hyperbaric Oxygen Treatment, access to hyperbaric facilities varies, and referral patterns seem to reflect different levels of acceptance of HBO2 as a potentially beneficial treatment. Analysis and publication of registry data is a valuable tool for educating us and establishing stronger treatment guidelines and recommendations.
