“…Another critical question was whether the auditory and speech performance of patients who underwent cochlear reimplantation were similar with that when they underwent the initial CI, which was assessed in <50% of studies. In some large cohort studies, effect evaluation or analysis was not performed ( Rayamajhi et al 2020 ; Aldhafeeri et al 2021 ; Layfield et al 2021 ). Because the follow-up data were not systematic and complete in large cohort studies, the analysis was limited ( Hermann et al 2020 ).…”

“…Since the 1970s, CIs have been continuously upgraded and optimized, and the age range and indications have been expanded. Meanwhile, the incidence of complications is gradually increasing as well (Roche & Hansen 2015; Aldhafeeri et al 2021; Dağkiran et al 2020). As an implantable electronic device, cochlear implants require reoperation and reimplantation due to severe complications such as device failure, pain, and infection (Terry et al 2015; Dağkiran et al 2020).…”

Objectives: In terms of cochlear reimplantation, there is no consensus on the definition, range, or calculation formulation for the reimplantation rate. This study aims to put forward a relatively standardized and more explicit definition based on a literature review, calculate the rate of cochlear reimplantation, and examine the classification and distribution of the reimplantation causes. Design: A systematic review and retrospective study. A relatively clearer definition was used in this study: cochlear reimplantation is the implantation of new electrodes to reconstruct the auditory path, necessitated by the failure or abandonment of the initial implant. Seven English and Chinese databases were systematically searched for studies published before July 23, 2021 regarding patients who accepted cochlear reimplantation. Two researchers independently applied the inclusion and exclusion criteria to select studies and complete data extraction. As the effect size, the reimplantation rate was extracted and synthesized using a random-effects model, and subgroup and sensitivity analyses were performed to reduce heterogeneity. In addition, a retrospective study analyzed data on cochlear reimplantation in a tertiary hospital from April 1999 to August 2021. Kaplan-Meier survival analysis and the log-rank test were adopted to analyze the survival times of cochlear implants and compare them among different subgroups. Results: A total of 144 articles were included, with 85,851 initial cochlear implantations and 4276 cochlear reimplantations. The pooled rate of cochlear reimplantation was 4.7% [95% CI (4.2% to 5.1%)] in 1989 to 2021, 6.8% [95% CI (4.5% to 9.2%)] before 2000, and 3.2% [95% CI (2.7% to 3.7%)] after 2000 (P=0.003). Device failures accounted for the largest proportion of reimplantation (67.6% [95% CI (64.0% to 71.3%)], followed by medical reasons (28.9% [95% CI (25.7% to 32.0%)]). From April 1999 to August 2021, 1775 cochlear implants were performed in West China Hospital (1718 initial implantations and 57 reimplantations; reimplantation rate 3.3%). In total, 45 reimplantations (78.9%) were caused by device failure, 10 (17.5%) due to medical reasons, and 2 (3.5%) from unknown reasons. There was no difference in the survival time of implants between adults and children (P = 0.558), while there existed a significant difference between patients receiving implants from different manufacturers (P < 0.001). Conclusions: The cochlear reimplantation rate was relatively high, and more attention should be paid to formulating a standard definition, calculation formula, and effect assessment of cochlear reimplantation. It is necessary to establish a sound mechanism for long-term follow-up and rigorously conduct longitudinal cohort studies.

“…A total of 119 patients (5.14%) had non-specific complications that were not mentioned by the authors of the included studies. The total rate of complications was 4-13%, with a lower rate of complications (4%) reported by Aldhafeeri et al [ 16 ], and the highest rate of complications (33.3%) reported by Fatani et al [ 6 ]. We excluded the case reports reported by Hajr et al [ 7 ] and AlHelali et al [ 19 ], in which one patient had a 100% rate of complications.…”

This review aimed to determine the incidence of complications associated with cochlear implants (CI) in Saudi Arabia. We systematically searched PubMed, AIRE, OaIster, MEDLINE, Directory of Open Access Journals, Scopus, and Ovid from inception to January 2024. The review protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO) (ID: CRD42023486687). Studies that reported CI complications in Saudi Arabia were included. This systematic review was conducted in accordance with PRISMA guidelines. A total of 17 articles with 2216 patients were included. The most common intraoperative complication was cerebrospinal fluid leakage (23 patients, 0.99%), followed by surgical difficulties (six patients, 0.26%), and dural accidental exposure and bleeding (three patients, 0.13%); the most common postoperative complications were vestibular symptoms (20 patients, 0.86%), followed by infection (17 patients, 0.73%), and device malfunction or migration (12 patients, 0.52%). The total complication rate ranged from 4-13%. Most of the included studies had a low risk. CI in Saudi Arabia has a complication rate similar to that reported in international studies. This review emphasizes the need for continued surveillance of CI outcomes to optimize procedural techniques and improve the safety and efficacy of CI in Saudi Arabia.

“…Moreover, it is worth noting that reimplantation rates tend to be higher in children than in adults 10 – 13 . During revision CI surgery, several surgical challenges may be encountered, such as the closure of the mastoid defect, neo-osteogenesis and fibrosis, which can result in device fixation 14 . These difficulties can lead to prolonged surgery duration and increased exposure to anesthesia, as drilling may be required to reopen the mastoid cavity 15 .…”

This retrospective study examined mastoid defects resulting from cochlear implant (CI) surgery and their potential for spontaneous regrowth across different age groups. Spontaneous closure of mastoid defects has been observed in certain CI patients during revision surgery or through post-operative temporal bone computer tomography (TB-CT). The analysis encompassed 123 CI recipients, comprising 81.3% children and 18.7% adults, who underwent post-operative TB-CT scans. Using image adjustment software, the study measured mastoid defect areas and found a significant reduction in children's defects between the initial and subsequent scans. Notably, mastoid defect areas differed significantly between children and adults at both time points. Furthermore, the analysis revealed significant correlations between mastoid defect areas and the age at implantation as well as the time elapsed since the CI surgery and the first CT scan. This study provides valuable insights for evaluating CI patients scheduled for revision surgery by assessing potential surgical challenges and duration. Furthermore, it may have a pivotal role in evaluating patients who experience postauricular swelling subsequent to CI surgery.
