| The membranous labyrinth and its compartments can be seen clearly in relation to the 5 vestibular end organs, the 2 divisions of the vestibular nerve and the facial nerve. Note the orientation of the maculae of the utricle and saccule, the complex form of the utricle, and the increasing diameter of the scala media from hook to apex. Anatomy will build around the labyrinth to create a trans-canal surgical view so that the true position of the labyrinth in the surgical field can be appreciated. |
