attempted to use the guidelines but only 50% applied

the guidelines correctly. This discrepancy has undoubtedly

generated significant perception differences over treatment

efficacy. Currently, no objective systematic analysis on

systematically analyze current ESS procedures using the

American Academy of Otolaryngology

Head and Neck

Foundation (AAO-HNS) guidelines to better quantify their

efficacy in controlling vertigo and preserving hearing in the

short and long term. It should be noted that this study did not

compare ESS to the natural history of MD (nonsurgical);

rather its focus was to explore possible outcome differences

in patients undergoing current ESS techniques.
