Abstract
• Audiologic and middle ear impedance test results were determined in two cases of surgically confirmed ossicular discontinuity. In each case, there was a conductive hearing loss, normal tympanometric findings, and an acoustic reflex. Causes associated with these findings previously included otosclerosis, osteogenesis imperfecta, and congenital absence of the stapes superstructure. A second type of congenital stapedial anomaly and trauma has been added to the pool of causes of ossicular chain disorders that permits the observation of acoustic reflexes with the impedance bridge.
