case_images: Fluctuating hearing levels affecting mainly the low- to midfrequencies in the right ear which corresponded to the fluctuating aural symptoms in the same ear. Audiogram done during the initial episode (a), after treatment with medications (b), during a subsequent episode (c), and after treatment with CPAP (d).
