The relationship between round window and ear canal Cochlear microphonic
Laryngoscope Investigative Otolaryngology, 2022 Hypothesis Cochlear microphonic recorded at ear canal (CM‐EC) can be a substitute for the one recorded at round window (CM‐RW). Background Almost all clinics do not measure tone‐burst evoked CM due to technical difficulty although it can provide more ...
