Introduction: Stapedectomy is a surgical procedure which replaces the stirrup, by Teflon or a metal prosthesis. It is indicated especially in cases of conductive hearing loss as a result of otosclerosis. It has been shown, in recent decades, as a good therapeutic option considering its low morbidity and high success rate. It can, however progress with some complications already described such as dislocation of the prosthesis, changes in taste, facial paralysis, vertigo, total extrusion of the prosthesis, tinnitus, and tympanic membrane perforation.

Objectives: This study aims to report a case of the late extrusion Teflon prosthesis after stapedectomy.

Case Report: A 39-year-old patient (P. P. M.) diagnosed with bilateral otosclerosis submitted to stapedotomy (left ear) with a good postoperative audiometric evolution. It has been 6 months now and the patient has complained of progressive hearing loss and fullness in the left ear, otoscopy viewing prosthesis extruding through the tympanic membrane.

Conclusion: The treatment found most effective for conductive hearing loss secondary to otosclerosis is surgery. The importance of clinical and postoperative audiometry examinations and imaging is evident. The probability of implant extrusion and other complications, even though the low rate may have even delayed onset. A stapedectomy is indicated for the treatment of otosclerosis, with good results therapeutic, however not without complications. Among them, the extrusion of the prosthesis may occur later and need surgical correction.
