About Video

This technique offers surgical access to the lateral skullbase including the cranial side of the petrous temporal bone, the internal auditory canal, the geniculate ganglion of the facial nerve and the petrous apex. It has been demonstrated here for two indications mentioned above. If necessary in the case of tumor removal, the middle fossa approach can be extended with a posterior fossa approach technique, such as retrosigmoid, or a trans- or retro-labyrinthine approach. Transmastoidal plugging of the superior semicircular canal can be considered as a good alternative in case of superior semicircular canal dehiscence, where the patient has moderate health conditions with severe complaints, since, by doing this, the physiologic function of the canal is lost.
