TORCH PROFILE IN COCHLEAR IMPLANTATION

Dr. J. Alagu vadivel

Abstract


BACKGROUND

           Early childhood torch infections are the important risk factor for severe to profound SNHL. To emphasize the importance of torch screening in infants and pregnant women could prevent and early identification of progression of hearing loss.

OBJECTIVE

             The aim of study is to find the role of TORCH ((toxoplasma, rubella, cytomegalovirus, and herpes simplex) infection and screening in children with bilateral profound SNHL in comparison with normal hearing children.

METHOD

             TORCH screening done in 122 patients with bilateral profound SNHL(cases) who underwent cochlear implants beween 2017 t0 2019 at Madurai Medical College &Govt.Rajaji Hospital, Madurai as well as 122 children with normal hearing(control) was conducted. Age group of both group was between 1 to 6 years. TORCH antibody status of both groups was compared.

RESULT

 From 122 patients, 32(26%) were positive for Rubella virus IgG antibody, 26(21%) positive for cytomegalovirus (CMV) IgG antibody and 11(9%) were positive for herpes simplex virus IgG antibody, , 14(11%) were positive for Rubella virus IgM antibody, 9(7.3%) positive for cytomegalovirus (CMV) IgM antibody and 2(1.6%) were positive for herpes simplex virus IgM antibody,

CONCLUSION

                From the above study it was evident that TORCH infections in test group is higher than control which suggests past history of TORCH infections during childhood as most important etiology of SNHL.
