Tympanosclerosis is a common sequela of chronic suppurative otitis media, mainly manifesting as tympanic membrane perforation, gradual hearing loss or with tinnitus, which can be long-term without pus flow. On examination, calcified spots can be seen in the residual tympanic membrane, and in more severe conductive deafness or mixed deafness, there can be calcified spots in the tympanic membrane, around the auditory chain and within the tympanic chamber on CT examination, which affects the activity of the auditory chain of the tympanic membrane and leads to gradual hearing loss, and often requires surgical treatment. Whether hearing can be improved depends on the degree and site of fixation of the auditory chain, and sometimes requires staged surgical treatment.
