Abstract
Objectives:To determine the prevalence of complications of cochlear implant surgery in children with congenital profound sensorineural hearing loss.Methods:This study retrospectively & consecutively reviewed charts of children who underwent cochlear implantation from July 2015 to July 2019 at Cochlear Implant Centre of Otolaryngology Department of Capital Hospital, Islamabad Pakistan. These included cases of both genders aged one to 12 years operated at least one year before the time of data collection. Basic demographic data, complications including major and minor complications and treatment received was noted and statistically analyzed using SPSS-23. Results were presented using descriptive statistics.Results:Current study included a sample of N=251 having a mean age of 4.05±2.15 years including 154(61.4%) males and 97(38.6%) females revealed a prevalence of complications of 16(6.4%) with 4(1.6%) major and 12(4.8%) minor complications. Wound infection and acute otitis media with frequency of 3(1.2%) each were the commonest complications, followed by , facial nerve twitching, tinnitus and vertigo, infection and extrusion; and device failure in 2(0.8%) each. However, there was no significant association of complications with age group and gender with P=0.344 and P=0.519 respectively.Conclusion:Present public sector implant program is characterized with a very low prevalence of complications of 16(6.4%) with 4(1.6%) major and 12(4.8%) minor complications. Wound infection and acute otitis media were the commonest complications.

Summary
Severe to Profound Hearing Loss has a prevalence of 6.7% in clinical population and 0.7% in general population as reported for United Kingdom’s National Health Service clinic[1] and a Correspondence: November 30, 2020 April 27, 2021 prevalence of 1.6 per 1000 cases with profound hearing loss alone has been reported from Pakistan.[2]. Pak J Med Sci September - October 2021 Vol 37 No 5 www.pjms.org.pk 1519 study.[6] Though cochlear implantation in cases with IEMs has favorable surgical and speech results[7] and is a safe procedure in experienced hands,[8] difficulties and intraoperative complications do occur.[9] Complications ranging from pain, minor bleed, infection, breakdown of skin, facial palsy, taste changes, vertigo, cerebrospinal fluid leak, device failure as well as mal-placement, skull base and brain damage to complete deafness and death may occur.[3] knowledge of associated risks is very important since it is not a lifesaving procedure rather it is responsible for reduction of disability and significantly improves quality of life (QoL).[10]
