ABSTRACT
Background:
To maximise the success of cochlear implantation, optimal placement of the electrodes inside the cochlea is required. Hearing preservation also means that intracochlear spaces must be approached in a way that avoids traumatising inner ear structures.
Material and Methods:
In order to examine this issue a literature search was performed targeting articles on surgical techniques used in partial deafness cochlear implantation. The aim was to evaluate the advantages and shortcomings of each technique.
Results:
In cochlear implantation two main approaches to the middle ear have been described: mastoidectomy/posterior tympanostomy and suprameatal. Two approaches to the inner ear are in use: cochleostomy and round window.
Conclusions:
From temporal bone studies and clinical work some general conclusion can be drawn: straight arrays should use round window insertion, and precurved arrays should use cochleostomy
