title: The insertion trajectory in cochlear implantation - comparison between two approaches.
abstract: CONCLUSIONS
  The suprameatal approach (SMA) for cochlear implantation is a safe procedure and is at least comparable to the classic mastoidectomy-posterior tympanotomy approach (MPTA) regarding the possibility of reducing electrode insertion trauma.
  
  
  OBJECTIVE
  To compare the trajectory in the SMA with insertion through cochleostomy, to the MPTA with round window insertion.
  
  
  METHODS
  Nine temporal bones were implanted by both techniques, and the point of first contact of a precurved electrode was compared.
  
  
  RESULTS
  With the SMA, in all bones, the point of first contact was the inferior wall of the scala tympani and insertion was into the scala tympani. In the MPTA, in five of the bones, the point of first contact was the modiolus, the osseous spiral lamina or the basilar membrane.
