Dehiscence of the cochlear otic capsule has recently been described as a pathologic entity. We describe two cases of cochlear‐facial dehiscence, which are the first reported: a 69‐year‐old male who complained of hearing loss, autophony, and pulsatile tinnitus and a 41‐year‐old female who complained of left‐sided hearing loss, pulsatile tinnitus, and vertigo. In both, computed tomography (CT) showed bony dehiscence between the facial nerve and cochlea. Cochlear‐facial dehiscence is another example of otic capsule dehiscence that produces symptoms of third‐window lesions. When patients present with symptoms of third‐window lesions and CT does not show superior canal dehiscence, cochlear‐facial dehiscence should be considered. Laryngoscope , 124:283–289, 2014
