ABSTRACT
Objective:
Chronic obstructive inflammation of the external ear canal after different kinds of surgeries often leads to restenosis. There are different approaches to treatment of such cases, and one solution is a middle ear implant. Here we analyze the efficacy of using the Vibrant Soundbridge middle ear implant with a new incus short process (SP) coupler in this type of case.

Material and Methods:
We present a case study of a 29-year old patient with bilateral mixed hearing loss caused by bilateral obstructive inflammation of the external ear canals. He had undergone meatoplasty with very short-lived improvement. Afterwards he qualified for middle ear implantation to restore hearing, and the Vibrant Soundbridge was implanted with a new SP coupler to which the floating mass transducer (FMT) is attached. Postoperative hearing tests included pure tone audiometry, free field audiometry, speech recognition, and APHAB questionnaire.

Results:
Speech recognition after implantation improved to 100%. Pre- and postoperative bone conduction thresholds were unchanged. Vibrometry thresholds 10 months after surgery did not deteriorate. There was a decrease in global APHAB score by 61% from 2 to 10 months after implantation.

Conclusions:
Application of the Vibrant Soundbridge middle ear implant can be an effective treatment in cases of hearing loss caused by obstructive inflammation of the external ear canals. The new incus SP coupler seems to be an effective method of stimulating the middle ear in mixed hearing loss.
