Introduction. The first cochlear implant surgery was performed at the Center for Cochlear Implantation of the Department of Ear, Nose and Throat Diseases, Clinical Center of Vojvodina in 2002 after long preparations and that was the first successful cochlear implantation in Serbia. Material and Methods. Over the period from November 2002 to November 2013, 99 patients underwent surgical procedures and 100 cochlear implants were placed. Results. The analysis encompassed 99 patients, the youngest and the oldest one being 1 year and 61 years old, respectively. Prelingual and postlingual deafness developed in 84 (84.9%) and in 15 (15.1%), respectively. Postlingual deafness was observed in all 11 adult patients. The prelingual deafness was diagnosed in 84 (95.4%) children, whereas in four (4.6%) children it occurred after the development of speech between 6 and 8 years of age. Progressive hearing loss was observed in 11 patients - seven adults and four children. The majority of our patien...

Postoperative complications in cochlear implants: a retrospective analysis of 438 consecutive cases
European Archives of Oto-Rhino-Laryngology, 2012
Our objective is to determine the complication rate in a population of infants, children, adolescents and adults, from a University Hospital Cochlear Implant program and to discuss their causes and treatments. The methods include a retrospective study of 438 consecutive patients in a tertiary referral centre, the Audiology Department of the University Hospital of Ferrara. All patients receiving cochlear implants, between 1 January 2003 and 31 December 2009, have been included. All complications and treatments were systematically reviewed with an average duration of follow-up of 46 months (range 10-84 months). The results reveal that the overall rate of complications in our group was 9.1% (40 of 438), and most of them were minor. Wound swelling and infections represent the most common complication occurred. There were no cases of transient or permanent facial palsy following surgery, and also we did not register any case of postsurgical meningitis. Thirteen patients (3.0%) underwent explantation followed by reimplantation. In conclusion, we find that Cochlear implantation is a safe low-morbility technique with a relatively low complication rate in the presented population.
Complications of post-cochlear implantation in 1027 adults and children
Annals of Saudi Medicine
BACKGROUND: The number of cochlear implant (CI) recipients is increasing so there needs to be greater awareness of possible CI complications. OBJECTIVES: Describe complications of CI. DESIGN: Retrospective, descriptional. SETTINGS: Tertiary health care center. PATIENTS AND METHODS: Data was collected by retrospective chart review on complications for recipients implanted for the period from January 2006 to June 2017. MAIN OUTCOME MEASURES: Major and minor post cochlear implantation complications. SAMPLE SIZE: 1027 cochlear implant recipients. RESULTS: Post-operative complications were reported in 105 patients (10.2%). Minor complications were most often encountered (9.5%). Swelling (wound seroma or hematoma) was the most common complication. The major complication rate was only 7/105, 0.7%. Meningitis did not occur and cholesteatoma occurred in only one patient. CONCLUSION: CI is a safe surgical procedure at our center. We believe that this is probably due to the preoperative protocol, the surgical technique used, and the postoperative care conducted for all our patients. Despite this, it is important that both physicians and patients have knowledge of the possible consequences and risks posed by CI, especially in view of the fact that these patients require lifetime followup. LIMITATIONS: Further studies are needed, and should include more ENT centers across all regions of Saudi Arabia.
Risk factors for complications in cochlear implant surgery
European archives of oto-rhino-laryngology : official journal of the European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino-Laryngology - Head and Neck Surgery, 2018
The objective of this study was to achieve uniform reporting of complications and failures in cochlear implantation, to analyze complications and failures and to identify risk factors for complications in a series of over 1300 cochlear implantations. In a retrospective chart review and observational study, data from all cochlear implantations from 1987 to 2015 were entered in a custom-made database. Complications were classified using the contracted form of the Clavien-Dindo system and risk factors were identified by statistical analysis. A complication rate of 18.4% and a device failure rate of 2.9% were found. There was a higher rate of hematoma in patients with a clotting disorder and when a subtotal petrosectomy was performed, a higher rate of wound infections in patients who were not vaccinated against Streptococcus pneumoniae and a higher rate of meningitis in patients with an inner ear malformation. The use of a strict definition of a medical complication and device failure-i...

UNLABELLED Cochlear implantation is a safe and reliable method for auditory restoration in patients with severe to profound hearing loss. OBJECTIVE To describe the surgical complications of cochlear implantation. MATERIALS AND METHODS Information from 591 consecutive multichannel cochlear implant surgeries were retrospectively analyzed. All patients were followed-up for at least one year. Forty-one patients were excluded because of missing data, follow-up loss or middle fossa approach. RESULTS Of 550 cochlear implantation analyzed, 341 were performed in children or adolescents, and 209 in adults. The mean hearing loss time was 6.3 ± 6.7 years for prelingual loss and 12.1 ± 11.6 years for postlingual. Mean follow-up was 3.9 ± 2.8 years. Major complications occurred in 8.9% and minor in 7.8%. Problems during electrode insertion (3.8%) were the most frequent major complication followed by flap dehiscence (1.4%). Temporary facial palsy (2.2%), canal-wall lesion (2.2%) and tympanic membr...
Complications of cochlear implant surgery
Srpski arhiv za celokupno lekarstvo, 2004
During the last several decades, cochlear implant has been fully recognized in treatment of severe hearing loss. Development of modern technology enabled inconceivable possibilities of technical qualities of the device as well as development of usable coding strategies, which led to extraordinary results in patient rehabilitation. Although cochlear implantation has become one of the routine operative procedures throughout the world nowadays, it gives rise to certain complications. These complications, though rare, can sometimes be very serious, even with fatal outcome. If cochlear implantation is performed by experienced and well-educated team of experts, the possibility of complications is minimal and is certainly not the argument against cochlear implantation as a method of treatment of severe hearing impairments.
Complications of paediatric cochlear implantation: experience in Izmir
Journal of Laryngology and Otology, 2005
Surgery for cochlear implantation (CI) bears the risks of complication associated with all major surgery, in addition to the particular risks associated with implanting a foreign body into the peripheral auditory system. Here we present a retrospective study involving 227 cochlear implant operations in 205 children to evaluate the rate of intra-and post-operative complications. Complications were defined as major complications, requiring explantation of the device or further operation, causing a significant medical problem, or leading to any degree of facial paralysis or requiring additional hospitalization for treatment; or defined as minor complications, namely those that settled spontaneously, with conservative treatment, with local care and/or with medication alone. In our study there were 15 (6.6 per cent) minor and 28 (12.33 per cent) major complications. The most frequent minor complication was dizziness and vomiting (3.08 per cent), followed by transient hemifacial oedema (1.76 per cent), head pain (1.32 per cent) and mild ataxia (0.4 per cent). The most frequent major complication was trauma to the device (9.69 per cent), followed by cerebrospinal fluid (CSF) gusher (2.2 per cent) and facial paresis (0.4 per cent). All of the device trauma cases were re-implanted. There were neither any life-threatening complications nor any facial nerve paralysis in our implanted children. This study confirms that CI is relatively safe and that major complications are few and within acceptable limits.

Objectives To list the complications encountered in a series of 844 consecutive patients and to evaluate the long-term difference in wound and flap problems between large and small incisions. Patients 844 consecutive patients underwent cochlear implantation at the Sydney Cochlear Implant Centre. 212 cases were operated on prior to October 1994 using the retroauricular 'C'-shaped incision or a postauricular incision with a horizontal posterior limb. After October 1994 a new, small vertical postaural incision was used in all patients. Postoperative problems were analysed. Study design Prospective longitudinal study of cochlear implant recipients from1984 to 2003. Setting Te rtiary care referral centre. Intervention Change in incision for cochlear implantation. Main outcome measure Causes of postoperative problems, need for reimplatation, and wound and flap problems. Results 80 out of the total 844 patients underwent revision procedures for various reasons. The commonest cause of reimplantation was device failure (2.01%) or suboptimum performance of the device (2.37%). Wound and flap problems were encountered by 5 patients out of 212 (2.3%) in the first group. In comparison, 7 out of 632 patients (1.10%) from the later group experienced wound and flap problems using the new incision.
