Does the surgical approach in cochlear implantation influence the occurrence of postoperative vertigo?

We present a case of a 50-year patient with a severe form of otosclerosis (double ring) that was successfully implanted. We used a bone-anchored hearing implant for restoring the hearing in the right side and a cochlear implant in the left side; both surgeries did not show any complications. For reducing the risk of a secondary bone ossification related to the trauma of cochleostomy for electrode’s insertion, we used a round window approach. The patient recovered a normal auditory threshold and normal speech perception capacity both in silence and noise conditions 1 year after surgery.

Facial Nerve Anatomy

Cochlear implantation becomes more common with every passing year. Since adequate exposure of the round window requires a facial recess approach, facial nerve variation and anomalies could potentially alter the surgical approach significantly. We report the case of a patient with a variation of facial nerve anatomy. The nerve was found to be lateral to the annulus in its mastoid segment and required retrofacial dissection to approach the round window. A good result was achieved in this patient, demonstrating that facial nerve anomalies need not be a barrier to successful implantation. The reported congenital anomalies of the facial nerve are discussed, along with their influence on cochlear implantation. A knowledge of these variations is mandatory for those engaged in implant surgery.

A Prospective Study

Previous studies have shown diverse and sometimes even contrary results concerning the effect of cochlear implantation on tinnitus and the factors that can influence this effect. The aim of this prospective questionnaire study was to determine the effects of cochlear implantation on tinnitus and explore which factors can influence the effect of cochlear implantation on tinnitus. Forty-four of the patients implanted in our hospital returned 2 questionnaire packages, i.e., one before the cochlear implantation and one 6 months after implantation. Before implantation, 66% of the patients experienced tinnitus. This study shows that cochlear implantation could help to reduce tinnitus and the tinnitus handicap in at least 28% of the patients with preoperative tinnitus. In 72% of the patients the tinnitus remained after implantation. None of the patients developed tinnitus after implantation. A shorter duration of tinnitus prior to implantation, a more fluctuating type of tinnitus, a higher tinnitus handicap prior to implantation, and a round-window surgical approach might have a positive influence on the effect of cochlear implantation on tinnitus, but further research is necessary to confirm these findings.
