“…Fifty‐nine articles (date range: 1993‐2015) were included in this systematic review, of which 23 studies 11‐33 had SP data and 57 studies 11‐29,32‐69 had surgical findings data, with a total of 213 patients with speech data and 692 with operative data. The search strategy is shown as a PRSIMA diagram in Figure 1.…”

Objective (1) To analyze reported speech perception outcomes in patients with inner ear malformations who undergo cochlear implantation, (2) to review the surgical complications and findings, and (3) to compare the 2 classification systems of Jackler and Sennaroglu. Data Sources PubMed, Scopus (including Embase), Medline, and CINAHL Plus. Review Methods Fifty-nine articles were included that contained speech perception and/or intraoperative data. Cases were differentiated depending on whether the Jackler or Sennaroglu malformation classification was used. A meta-analysis of proportions examined incidences of complete insertion, gusher, and facial nerve aberrancy. For speech perception data, weighted means and standard deviations were calculated for all malformations for short-, medium-, and long-term follow-up. Speech tests were grouped into 3 categories-closed-set words, open-set words, and open-set sentences-and then compared through a comparison-of-means t test. Results Complete insertion was seen in 81.8% of all inner ear malformations (95% CI: 72.6-89.5); gusher was reported in 39.1% of cases (95% CI: 30.3-48.2); and facial nerve anomalies were encountered in 34.4% (95% CI: 20.1-50.3). Significant improvements in average performance were seen for closed- and open-set tests across all malformation types at 12 months postoperatively. Conclusions Cochlear implantation outcomes are favorable for those with inner ear malformations from a surgical and speech outcome standpoint. Accurate classification of anatomic malformations, as well as standardization of postimplantation speech outcomes, is necessary to improve understanding of the impact of implantation in this difficult patient population.

Background: Cerebrospinal fluid (CSF) gusher is a common complication experienced during cochlear implantation in patients with structural deformities in the inner ear. Objectives: This study aimed to investigate the incidence of CSF gusher, risk factors, and outcomes in patients during cochlear implantation. Methods: This systematic review and meta-analysis were guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses model. Studies used in the analysis were identified through a comprehensive search in Google Scholar and PubMed. Results: The analysis was performed using 13 retrospective studies. The incidence of CSF gusher was 5% (95% CI: 3%-9%). CSF gusher was more prevalent among patients with inner-ear malformation (IEM) than without IEM odds ratio = 63.01 (95% CI: 9.85-403.11, P < .00001, I2 = 88%). For incomplete partition (IP), CSF gusher in the IP-I group was 48% (95% CI: 25%-71%, I2 = 0%), 19% in IP-II, 86% in IP-III, 40% in the common cavity, 26% in cochlear hypoplasia, and 27% in patients with enlarged vestibula aqueduct. Conclusion: The CSF gusher incidences were determined to be 5%. Patients with IEM are at increased risk of experiencing CSF gusher during cochlear implant surgery. Therefore, precise scanning reports should be produced in preoperational phase to inform proper management techniques to reduce the chances of intraoperative complications, including CSF gusher.
