To describe cochlear implantation (CI) outcomes, with speech perception, auditory, language, and parent-reported auditory and speech behaviors, in children with an enlarged vestibular aqueduct (EVA) and incomplete partition type 2 (IP-II) and compare to control children without inner ear malformations (IEMs) and to determine cerebrospinal fluid gusher rates and effect on outcomes.Study Design: Systematic review and meta-analysis. Methods: MEDLINE, Embase, Cochrane, and CINAHL databases were searched from inception to February 2020. Studies reporting relevant outcomes in children with EVA or EVA + IP-II and controls without IEMs undergoing CI were included. Mean differences in speech perception, auditory, and language scores between cases and controls were meta-analyzed. Gusher rates were determined by proportion meta-analyses.Results: Of 214 identified articles, 42 met inclusion criteria, evaluating 775 cases and 2,191 controls. Of -cases, 578 (74.6%) had EVA and 197 (25.4%) had EVA + IP-II. Cases showed a significant improvement in speech perception, auditory and language performance, comparable to controls. Parent-reported auditory and speech production behaviors outcomes were positive among cases and comparable to controls. Pooled gusher proportions in EVA and EVA + IP-II cases were 27.7% (95% CI: 17.6-39.1) and 48.6% (95% CI: 28.6-69.0), respectively, with a proportion difference of 20.9% (95% CI: 11.0-30.1). Gusher occurrence did not impact speech perception or language outcomes.Conclusion: Outcomes in children with EVA or EVA + IP-II undergoing CI are favorable and largely comparable to outcomes in children with hearing loss undergoing CI without IEMs. Intraoperative gusher is more prevalent among children with EVA + IP-II as compared to iEVA. Gusher does not influence speech perception and language development outcomes.

“…Thirty out of the 64 studies, involving a total of 551 cases with an isolated enlarged vestibular aqueduct, have reported considerable benefit in the audiology and speech performance after CI. In several studies, involving 2914 patients which included 419 inner ear malformation concluded that the outcome of patients with inner ear anomalies are like patients with the normal inner ear [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. There are several studies which have compared the audiological outcome of patients with the control group being "normal inner ear anatomy", these studies having 391 patients as a result from the outcome of inner ear anomalies which is equal to the control group (n=1436) [9][10][11][12][13][14][15]17,[19][20][21][22].…”

To analyze the outcome of a cochlear implant (CI) in patients with an inner ear malformation (IEM), to compare two commonly used classification systems for IEM, to identify the highest and lowest outcome performance of IEM, to determine the most frequent inner ear anomalies and a candidate for a cochlear implant with considerable improvement.Methods: A literature review including 64 previously published studies between the period 1987 to 2020. In addition, a retrospective study inclusive 16 cases with IEM having undergone 20 CI surgeries. Results:The review shows that 43 studies involving 1273 (19%) cases with IEM out of 6560 patients have demonstrated an improvement in auditory and speech performance after implantation. 30 studies involving a total of 551 cases with an isolated enlarged vestibular aqueduct (EVA) have reported considerable benefits in audiology and speech performance after CI. Several authors reported that patients who have mild anomalies have a better outcome than patients who have severe malformations. Clinical studies revealed that patients with IEM have seen improvements in the outcome of audiology and speech tests after implantation. Conclusion:CI is effective for patients who have severe to profound sensorineural hearing loss (SNHL) with inner ear anomalies despite other factors which may influence the outcome. The outcome of the minor IEM such as EVA is higher than the performance of the major anomalies like a common cavity (CC). The most frequent inner ear anomaly and candidate for the CI with significant improvement after implantation is EVA.

“…For patients with inner-ear malformations, clinical physicians and the family of the patients are more concerned with how to guarantee the efficacy of cochlear implantation in terms of the hearing ability of the patients. In addition, clinical physicians are urgently seeking a method that can accurately predict the postoperative hearing ability before implantation [3]. Furthermore, the test of residual hearing for patients before implantation serves as an important method for evaluating the function of auditory nerves and the efficacy of implantation.…”

Objective: This study aims to investigate the correlation between thresholds of preoperative multiple auditory steady-state response (ASSR) and electrically evoked auditory brainstem response (EABR) and the behavioral threshold. Methods: A total of 72 patients were elected to receive a multichannel cochlear implant. According to the residual hearing determined in a preoperative test using high-, moderate-, and low-frequency ASSR, these patients were divided into the following 2 groups: residual hearing and hearing loss. The EABR and behavioral thresholds 1 year after implantation were assayed, and differences between these 2 parameters were compared. Results: Among the high-, moderate-, and low-frequency residual hearing groups, the EABR and behavioral thresholds of patients 1 year after implantation were significantly lower than those in the hearing loss group, and the differences were statistically significant (p < 0.01). Conclusion: Before the operation, ASSR results can be used to predict the efficacy of cochlear implantation in patients, and they serve as one of the reference conditions for choosing the ear for implantation. However, the threshold of ASSR is not equivalent to the actual auditory threshold of patients after implantation, and the deviation between these 2 thresholds is more significant at low frequencies.
