Experience and evolution of surgical technique over 1 100 independent cochlear implant surgeries
Singh S.
Saket City Hospital, ENT and Cochlear Implants, New Delhi, India
Introduction: Posterior tympanotomy approach for cochlear implantation is a very well established surgical
technique. However complexity of anatomy, proximity to facial nerve and lack of training opportunity confines this
surgical practice to only select centers worldwide. Inspite of available detailed description and videos, there are
many aspects of this surgical technique that the surgeon needs to evolve on his own, especially with respect to
some steps like exposure of incus, posterior tympanotomy, cochleostomy and electrode insertion. Various
different types of descriptions are available for all these steps in literature but there is no substitute to evolution
with personal experience.
Method: Retrospective study
Results: This paper attempts to describe surgical practice and how it changed over the course of 1 100
independent surgeries carried out by the author.
Conclusion: The study attempts to identify significant though subtle changes in surgical procedure that allowed
surgery to complete in significantly shorter duration of time with more objectivity and confidence.
