Abstract
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.

The Risk of Meningitis After Cochlear Implantation: A Systematic Review and Meta-Analysis. Otolaryngol Head Neck Surg 2023; 169:467-481. [PMID: 36864717 DOI: 10.1002/ohn.309] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 02/05/2023] [Accepted: 02/08/2023] [Indexed: 03/04/2023]
Abstract
OBJECTIVE This study aims to estimate the rate of postoperative meningitis (both immediate and long-term) in patients following cochlear implants (CIs). It aims to do so through a systematic review and meta-analysis of published studies tracking complications after CIs. DATA SOURCES MEDLINE, Embase, and Cochrane Library. REVIEW METHODS This review was performed in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies tracking complications following CIs in patients were included. Exclusion criteria included non-English language studies and case series reporting <10 patients. Bias risk was evaluated using the Newcastle-Ottawa Scale. Meta-analysis was performed through DerSimonian and Laird random-effects models. RESULTS A total of 116/1931 studies met the inclusion criteria and were included in the meta-analysis. Overall, there were 112 cases of meningitis in 58,940 patients after CIs. Meta-analysis estimated an overall rate of postoperative meningitis of 0.07% (95% confidence interval [CIs], 0.03%-0.1%; I2 = 55%). Subgroup meta-analysis showed this rate had 95% CIs crossing 0% in implanted patients who received the pneumococcal vaccine, antibiotic prophylaxis, those with postoperative acute otitis media (AOM), and those implanted less than 5 years. CONCLUSION Meningitis is a rare complication following CIs. Our estimated rates of meningitis after CIs appear lower than prior estimates based on epidemiological studies in the early 2000s. However, the rate still appears higher than the baseline rate in the general population. The risk was very low in implanted patients who received the pneumococcal vaccine, antibiotic prophylaxis, received unilateral or bilateral implantations, developed AOM, those implanted with a round window or cochleostomy techniques, and those under 5 years.

Alahmadi A, Abdelsamad Y, Salamah M, Alenzi S, Badr KM, Alghamdi S, Alsanosi A. Cochlear implantation in adults and pediatrics with enlarged vestibular aqueduct: a systematic review on the surgical findings and patients' performance. Eur Arch Otorhinolaryngol 2022; 279:5497-5509. [PMID: 35771280 DOI: 10.1007/s00405-022-07511-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Accepted: 06/13/2022] [Indexed: 01/04/2023]
Abstract
PURPOSE Cochlear implantation (CI) has been considered a safe and effective management option for patients with severe to profound hearing loss. Patients with enlarged vestibular aqueduct (EVA) could be challenging with some variations in surgical approaches, intraoperative surgical notes, and clinical outcomes. This study aimed to review the surgical and clinical outcomes of cochlear implantation among patients with EVA. MATERIALS AND METHODS A systematic literature search was carried out in five major databases. All original studies reporting cochlear implantation in patients with EVA were included for qualitative data synthesis. The risk of bias was independently assessed through the National Intuitional of Health tool. The review protocol was registered in PROSPERO (reference number: CRD42021225900). RESULTS A total of 34 studies with 4035 subjects were included. Of them, 853 (21.14%) had EVA and underwent CI. Mondini malformation was the most frequently associated anomaly (n = 78, 11.1%). Unilateral implantation was performed in 258 cases while bilateral in 119 subjects. Postoperative complications included CSF/perilymph gusher (n = 112), CSF oozing (n = 18), and partial electrode insertion (n = 6). Closing the cochleostomy with temporalis fascia, muscle, connective tissue, or fibrin glue was the most frequently reported approach to manage CSF/perilymph gusher (n = 67, 56.7%) while packing was performed in six patients. CONCLUSION Patients with EVA demonstrated audiometric and speech performance improvement after CI. However, many patients had intra- or postoperative complications. Further research is needed as the outcomes may be affected by associated temporal bone pathology, the timing of implant, and hearing condition.
