The cochlear implant is a
prosthesis that is capable of restoring hearing function in sensorineural
hearing loss patients. Among post-lingual deafened adults, with different
periods of sound deprivation, and associated with social isolation, we analysed
surgical and audio logic outcomes. The
occurrence of vertigo or tinnitus during pre- and post-operative periods and
the result of speech therapy. A retrospective research was carried out on
patients aged over 18 years with post-lingual hearing loss who underwent
cochlear implant surgery at our institution from 2004 to 2014. Two classes were
analysed. Group A consisted of 38 respondents (14 male and 24 female) with
tone. Deprivation of less than 10 years;
and group B consisted of 17 participants with sound deprivation of more than 10
years (8 male and 9 female). We found no differences with respect to age , sex,
Sound deprivation length, mean audiometric pure-tone results (pre- and
post-surgery), and measures of speech perception (pre-operatively). A
substantial difference between the two groups was found after one year of
surgery, with better results compared to group A. The effects of speech The vision test was weaker than the findings
obtained in group A following cochlear implantation in group B, but these
associations do not decide whether or not cochlear implant surgery should be
performed.
