Postoperative complications of otosclerosis

Plunger placement in the treatment of otosclerosis can be associated with functional failures related to the plunger. CT plays a vital role in exploring the piston and detecting the causes of failure. We report the cases of 26 boulders operated on for otosclerosis with insertion of a piston, and who were explored by postoperative CT scan in the face of a recurrence of symptomatology or the appearance of a complication (clinical or audiometric). The average age of our patients was 45. CT scans were indicated in 11 cases of vertigo, audiometric abnormalities such as cophosis (4 cases), labyrinthisation (9 cases), persistence or reopening of the Rinne (6 cases). The piston was in place in 12 cases, depressed in 3 cases, displaced with a ring attached to the BDE in 5 cases, short in 2 cases and completely dislocated in 4 cases. At the end of this study, it appears that CT is the examination of choice for detecting postoperative complications of otosclerosis linked to the piston.
