We report a new cause of pulsatile tinnitus: a focal defect of the mastoid bone shell in the region of the transverse-sigmoid junction, with a normal transverse-sigmoid sinus.<\/jats:p><\/jats:sec><jats:sec id=\"S0022215111003458_sec2\"><jats:title>Participants and intervention:<\/jats:title><jats:p>Three patients complained of unilateral, pulsatile tinnitus present for many years. They were identified as having a focal defect of the mastoid bone shell in the region of the transverse-sigmoid junction.
