The present patent application refers to a system (100) for the detection of the stapedial reflex in a patient wearing a cochlear implant (60) or a hearing aid, when such patient undergoes an external stimulation of the cochlear implant or to the hearing aid, as well as a method for detecting the stapedial reflex which can be implemented by means of such system (100). The system (100) comprises: - a probe (30) apt to be inserted in the ear (20) of the patient, comprising an emitting source (31) configured to emit a probe tone (31') in such a way as to generate an acoustic pressure reflected from the tympanic membrane following the contraction of the stapedius muscle of the ear (20), and at least one microphone unit (35) apt to detect in continuous mode, an acoustic pressure reflected (35') from the tympanic membrane following the contraction of the stapedius muscle； - a control unit (40) in data communication with the probe (30) and configured to receive data related to the acoustic pressure reflected (35') detected by the microphone unit (35)； and - program means (50) connected to said control unit (40) and configured to process the data received from the control unit (40) in such a way as to obtain data indicative of the stapedial reflex and impedance change mapping data corresponding to changes in acoustic pressure reflected (35'). The program means (50) can be connected to display means comprising at least one screen, in such a way as to allow the simultaneous display on a single plane, according to a continuous mode, of data indicative of both the stapedial reflex and the field of dynamic variation of the mapping data generated by the proprietary software of the company manufacturing the cochlear implant or the hearing aid to be adjusted.La présente invention concerne un système (100) pour la détection du réflexe stapédien chez un patient portant un implant cochléaire (60) ou un appareil auditif, lorsqu'un tel patient subit une stimulation externe de l'implant
