Pneumo-membranous labyrinth is an almost unique condition, in which air extends into the membranous labyrinth, filling the endolymphatic sac through the vestibular aqueduct. In this manuscript, we describe and discuss a case of pneumo-membranous labyrinth, with air bubbles extending also to the endolymphatic sac, resulting in anacusis, following hyperbaric oxygen therapy for sudden sensorineural hearing loss. The patient was successfully rehabilitated with a cochlear implant, obtaining a pure-tone average of 30 dB, with a speech discrimination score of 100% at 70 dB. Laryngoscope, 134:3773-3777, 2024.
