Cochlear Implantation

Cochlear Implantation

Minimal Invasive Technique (VERIA) for Cochlear Implantation

The conventional or the classic technique uses a mastoidectomy & posterior tympanotomy approach to the middle ear & the cochlea. Though it is a successful technique it is more time consuming & prone to various complications specially in small children with a small Facial Recess, anomalies of the cochlea, cochlear rotation, etc. In the era of Minimal invasive techniques & need for better accessibility (of the cochlea in this case) the Trans-canal or the Veria Technique is very helpful. This technique is almost becoming essential now, since the time cochlear implantation has been started in children.

In this case a Trans-canal Tunnel is created with a special "Perforator" in the cortex of the posterior canal wall, which enters the middle ear through the facial recess. A tympano-meatal flap is elevated to do the Cochleostomy & insertion of the electrode in the scala-tympani.

I have done over 1800 cases by this technique, in my centre and in centers around India and SAARC countries including Pakistan & Bangladesh, with no surgical complications till date and withvery good post-op results, in patients ranging from 9 months to 79 years, both pre-lingual & post lingual.

Varity of cases with Middle ear cleft anomalies like dehiscent high jugular bulb, anteriorly placed sigmoid sinus; Cochlear anomalies like Mondini & Single cavity cochlea; Cochlear dystrophies (osteogenesis imperfecta); Cochlear ossification etc. were done. Situations like Intra-op CSF Gusher’s were dealt with ease.

I have used all the 4 Cochlear Implant systems available in the world namely Med'el, Nucleus, Advanced Bionics and Neuralac Digisonic, with very good results by this techniques.
