Long-term outcomes and electrophysiological measures of children with inner ear malformations and cochlear implants. Int J Pediatr Otorhinolaryngol 2024; 178:111875. [PMID: 38364548 DOI: 10.1016/j.ijporl.2024.111875] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2023] [Revised: 01/16/2024] [Accepted: 01/25/2024] [Indexed: 02/18/2024]
Abstract
OBJECTIVES To compared auditory and speech performance outcomes of children with cochlear implants (CI), between those with inner ear malformations (IEMs) and with normal ear anatomy; and to describe differences in electrophysiological measurements. STUDY DESIGN A retrospective study. SETTING A tertiary care pediatric medical center. PATIENTS Forty-one children with IEMs who underwent CI during 2003-2017, and 41 age-matched CI recipients with normal ear anatomy (control group). MAIN OUTCOME MEASURES Post-CI auditory performance outcomes including educational setting, Categories of Auditory Performance (CAP), and Speech Intelligibility Rating (SIR); and electrophysiological measurements, Including maximal comfortable electrical levels (CLs) and impedances along CI electrodes. RESULTS The ANOVA on ranks revealed lower CAP scores in the study than control group: H3 = 18.8, P < 0.001. Among children with IEMs, CAP scores were better in children with enlarged vestibular aqueduct (EVA) (P < 0.04). SIR scores of the control group did not differ from those with isolated EVA; however, SIR scores of the IEMs without EVA subgroup were lower than all the other study subgroups (P < 0.01). The proportion of the control group that was integrated with full inclusion educational settings into the regular mainstream schools was higher than for those with IEMs without EVA (47 % vs. 15 %, P < 0.05), but similar to those with isolated EVA. For the study group versus control group, maximal comfortable electrical levels (CLs) were higher)P > 0.03) while impedance measurements were similar. CONCLUSIONS Outcomes of pediatric recipients with normal anatomy were better than those with IEMs. Among pediatric recipients of CI with IEMs, auditory performance was better and CLs were lower among children with isolated EVA than all other IEM subgroups.

Abstract
Background and objective Cochlear implants are highly effective for the treatment of severe to profound hearing loss. Cochlear implant surgery is a safe surgical procedure; however, due to many modifications over the years, it has been associated with certain minor and major complications. This study aimed to examine the intraoperative difficulties and postoperative complications in patients who received cochlear implants in Erbil City. Methods We conducted a retrospective descriptive study regarding complications of cochlear implants involving patients who received unilateral or bilateral cochlear Implants at the Rizgary Teaching Hospital and a private hospital in Erbil City from January 2013 to July 2022. Their medical records were analyzed, and data on demographics, intraoperative difficulties, and postoperative complications were gathered. Results A total of 160 patients with cochlear implants (87 male, 54.4%; 73 female, 45.6%) were included in the study. The mean age of the patients at the time of operation was 6.76 ± 8.02 years (range: 1-53 years); 150 of these patients were children and 10 were adults (18 years and above). Intraoperative difficulties occurred in five patients (3.1%). The overall rate of complication was 10%, 7.5% of which was minor (the most common being wound infection) and 2.5% major (the most frequent being device extrusion). Conclusions Cochlear implant surgery is a safe procedure performed to treat profoundly deaf patients. It is associated with a low rate of complications, most of which can be successfully managed with conservative measures or minimal intervention.

[PMID: 36269710 PMCID: PMC9586398 DOI: 10.1371/journal.pone.0275543] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Accepted: 09/19/2022] [Indexed: 11/26/2022] Open
Abstract
OBJECTIVES To evaluate the outcomes of cochlear implantation in patients with severe to profound sensorineural hearing loss due to inner ear malformations (IEMs) when compared to patients without IEMs. We discussed audiological outcomes such as open-set testing, closed-set testing, CAP score, and SIR score as well as postoperative outcomes such as cerebrospinal fluid gusher and incomplete insertion rate associated with cochlear implantation in individuals with IEMs. DATA SOURCES PubMed, Science Direct, Web of Science, Scopus, and EMBASE databases. REVIEW METHODS After screening a total of 222 studies, twelve eligible original articles were included in the review to analyze the speech and hearing outcomes of implanted patients with IEMs. Five reviewers independently screened, selected, and extracted data. The "Tool to Assess Risk of Bias in Cohort Studies" published by the CLARITY group was used to perform quality assessment on eligible studies. Systematic review registration number: CRD42021237489. RESULTS IEMs are more likely to be associated with abnormal position of the facial nerve, raising the risk of intraoperative complications. These patients may benefit from cochlear implantation, but audiological outcomes may also be less favorable than in individuals without IEMs. Furthermore, due to the risk of cerebrospinal fluid gusher, incomplete insertion of electrodes, and postoperative facial nerve stimulation, surgeons can employ precautionary measures such as preoperative imaging and proper counseling. Postoperative imaging is suggested to be beneficial in ensuring proper electrode placement. CONCLUSIONS Cochlear implants (CIs) have the potential to provide auditory rehabilitation to individuals with IEMs. Precise classification of the malformation, preoperative imaging and anatomical mapping, appropriate electrode selection, intra-operative techniques, and postoperative imaging are recommended in this population.

Abstract
BACKGROUND AND OBJECTIVES In cochlear implant (CI) surgery, the results and causes of revision and reimplantation may guide surgeons in establishing surgical protocols for revision surgery with safe audiological outcomes. The aim of this study was to review our experience in terms of etiology, surgical strategy, and hearing outcomes in pediatric patients who underwent CI removal and reimplantation. SUBJECTS AND PURPOSE All patients received implants of the same brand. Pre and postoperative Categories of Auditory Performance score and aided free-field pure tone audiometry thresholds were noted. In vivo integrity tests were performed for each patient and the results of ex vivo tests of each implant were obtained from manufacturer. RESULTS A total of 149 CIs were placed in 121 patients aged <18 years. The revision rate in children was 6.7% (10/121 children). Six patients had a history of head injury leading to a hard failure. The causes of reimplantation in others were soft failure (n=1), electrode migration (n=1), infection (n=1), and other (n=1). All patients showed better or similar postreimplantation audiological performance compared with pre-reimplantation results. CONCLUSIONS It is very important to provide a safe school and home environment and educate the family for reducing reimplantation due to trauma. Especially for active children, psychiatric consultation should be continued postoperatively.

Abstract
OBJECTIVE(S) 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. LEVEL OF EVIDENCE NA Laryngoscope, 2021.

Abstract
OBJECTIVE. The purpose of this article is to provide an illustrative review of nonsyndromic congenital causes of sensorineural hearing loss (SNHL) in children. CONCLUSION. Early recognition and treatment are essential in maximizing developmental outcomes in children with congenital SNHL. Because imaging plays an integral role in identifying underlying causes of SNHL, it is imperative that radiologists be able to recognize, describe, and appropriately categorize the spectrum of congenital inner ear malformations in children.

Abstract
BACKGROUND Perilymph gusher (PLG) is a rare complication of otologic surgery attributed to a communication between the cochlea and the internal auditory canal (IAC). Subtle patency between the cochlear basal turn and IAC has recently been identified on computed tomography (CT) as a risk factor, specifically when the defect is > 0.75 mm. OBJECTIVES Investigate the prevalence of radiographic cochlear basal turn patency. MATERIALS AND METHODS Patients with CT of the temporal bones and inner ears interpreted as "normal" were included. An otologist and a radiologist independently reviewed CTs to measure radiographic dehiscence in an oblique plane along the interface of the cochlea and IAC. Known PLGs were excluded. RESULTS Two hundred and ten ears were included (88 conductive or mixed hearing loss, 62 sensorineural hearing loss, 41 audiometrically normal ears). 71 ears (33.8%) were radiographically patent. Mean defect width was 0.41 mm (0.15-0.7 mm). Defect width was not associated with type of hearing loss, age, or gender. No defects were wider than 0.75 mm. CONCLUSIONS Radiographic patency of the cochlear basal turn may be present in patients with hearing loss and normal hearing, but patency > 0.75 mm (i.e. risk for PLG) is rare.

Abstract
Introduction: Cochlear implants (CI) is considered a safe procedure with overall complication rate of 12.5% amongst adult and pediatric population. Cerebrospinal fluid (CSF) gusher is regarded as a common CI intraoperative complication.Objective: In this study, we determined the association between probable associated factors and occurrence of intraoperative CSF gusher.Method: In a retrospective survey, 394 patients with severe to profound sensorineural hearing loss who underwent primary cochlear implantation surgery were evaluated. Patients with incomplete electronic or manual file and those with revision, explantation or reimplantation surgery were excluded.Result: three hundred and ninety-four CI patients with a mean age of 8.74 ± 12.21 years were reviewed 49.62% of them were female. CSF gusher developed in 22 patients (5.58%). Patients with CSF gusher had more structural abnormalities in their CT scans' report. Common cavity malformation and Mondini dysplasia were the most common abnormal reports amongst those with intra-operative CSF gusher.Conclusion: In conclusion, cochlea structural abnormalities affect the incidence of CSF gusher in CI recipients. Common cavity malformation and Mondini dysplasia were associated with an increased incidence of CSF gusher. We insist on more precise pre-operative imaging of those with abnormal cochlea structures to provide the needed management.

Abstract
OBJECTIVES Perilymphatic gusher (PLG) is an uncommon complication of stapedectomy and cochlear implant placement. Computerized tomography (CT) may reveal congenital dysplasia responsible for PLG but may also be (incorrectly) interpreted as normal. The aim of this study was to review CT findings in patients with PLG reported to have normal temporal bones. PATIENTS Patients in which a PLG was encountered and preoperative CT imaging had been interpreted as normal. INTERVENTION Collaborative review of temporal bone computed tomography by neurotologist and neuroradiologist. MAIN OUTCOME MEASURE Identification of undetected inner ear anomalies that may predispose to PLG. RESULTS Unanticipated PLG was encountered during stapes surgery in two patients and cochlear implantation in one. A focal bony dehiscence between the basal turn of the cochlea and internal auditory canal (IAC) was identified on a few oblique reformatted images in all patients. CONCLUSIONS High resolution CT with oblique image reformatting is essential to identify focal communication between the IAC and basal turn of the cochlea in ears with PLG.

Abstract
OBJECTIVES Perilymph gusher (PLG), an uncommon complication of otologic surgery, has been attributed to communication between the cochlea and the internal auditory canal (IAC). Subtle osseous defects may be missed on routine review of computed tomography (CT). This study aimed to quantify cochlear basal turn patency not seen on axial CT in patients with PLG and compare those against patients without intraoperative PLG. METHODS Ears that underwent cochlear implantation or stapedotomy with preoperative helical CT that was interpreted as "normal" at a tertiary referral center. An otologist and a radiologist independently and in a blinded fashion measured the dimensions of cochlear basal turn patency on CT images in oblique plane and parasagittal planes along the interface of the cochlea and IAC fundus. RESULTS Sixty-one ears were reviewed, including 3 with surgically confirmed PLGs and 12 with apparent dehiscence without a PLG. Mean defect width with PLG was 0.83 mm (range 0.75-0.9 mm) and without PLG was 0.43 mm (range 0.3-0.65 mm, p = 0.011). A greater proportion of PLGs occurred in ears with defects (3 of 15) than in ears without (0 of 46, p = 0.013). Using a cutoff of 0.75 mm, a greater proportion of PLGs occurred with defect width >0.75 mm (3 of 3) than in defects <0.75 mm (0 of 12, p = 0.022). CONCLUSIONS CT dehiscence between the IAC and cochlear basal turn, particularly with a width > 0.75 mm, should be considered a risk for PLG with stapedotomy or cochlear implantation.
