To perform surgery with a minimally invasive procedure is preferred
during daily practices. With the endoscope development in otology, a
direct view of ossicles or lesions in the tympanic cavity without
disturbing the mastoid becomes possible. Accompanied by a growing number
of endoscopic surgeries, the complications were more commonly seen due
to certain drawbacks, like single-hand practices and loss of
three-dimensional images[1]. Rarely, to our knowledge, dislocated
stapes protrudes into the vestibule cavity during endoscopic surgery,
which results in profound hearing loss and vertigo.
