A modified form of the St Thomas' Hospital (STH) classification to improve cochlear implantation outcomes.

Objectives: re-evaluation and modification of the St Thomas' Hospital (STH) classification to improve cochlear implantation outcomes. STUDY DEIGN: a prospective cohort study.

Patients: children (n = 20) between 2 to 8 years old who received a unilateral cochlear implant, all had difficult round window visibility and/or accessibility for electrode insertion.

Cochlear implantation outcomes with round window electrode insertion versus cochleostomy insertion.

Objectives: assessment of two techniques for electrode insertion during cochlear implantation which are the round window and the traditional cochleostomy insertions, the comparison utilized cochlear implantation outcomes. STUDY DEIGN: a prospective cohort study.

Patients: children (n = 200) between 2 and 8 years old who had bilateral severe to profound SNHL and received a unilateral cochlear implant, 100 children had a round window insertion and were labeled the RW group while the other 100 children had a cochleostomy insertion and were labeled the C group which was taken as a control group.
