Deafness impacts both individuals and families, making cochlear implantation (CI) vital for those with hearing loss. Success in CI relies on factors like proper patient selection, electrode placement, and postoperative monitoring. Studies show deeper electrode insertion and more active electrodes improve speech perception, while optimal angles and electrode lengths enhance outcomes. Despite advancements, the long-term effects of changes in electrode insertion angle on speech, language, and societal integration remain underexplored. This study aimed to address this gap by examining these long-term effects. Methods: Sixty children with bilateral congenital profound sensorineural hearing loss who were implanted via a conventional posterior tympanotomy round window approach prior to 5 years of age were analyzed for angle of insertion using postoperative X-ray (Modified Stenver\u2019s view). Insertional angle \u201cICI\u201d (immediate postoperatively) and \u201cTCI\u201d (3 years after CI) were assessed for angle change. Both the observers measuring the insertion angle were blinded by each other. The outcome analysis of each implant recipient was performed under the domains of hearing, speech, language and integration into society. The hearing domain was assessed using the Revised Category of Auditory Performance (CAP), aided audiogram, and Functioning after Pediatric Cochlear Implantation (FAPCI), speech assessed using the Speech Intelligibility Rating (SIR) and Meaningful Use of Speech Scale (MUSS) questionnaires, language assessed using the Extended Receptive Expressive Emergent Language Scale (REELS), and subjective evaluation of the implant recipient\u2019s ability to integrate into society based on educational attainment. Results: The angle of insertion at 2 time points was compared. No statistically significant difference was observed (paired Wilcoxon test: v-367.0, p = 0.122) between the two measurements. Outcome analysis in hearing, speech, and language scoring suggested that a cochlear insertion angle of 270\u2013360\u00b0 produced better outcomes than a complete cochlear insertion. Conclusion: Over a long time period, we observed a minimal, yet not statistically significant, change in the angle of electrode insertion. It can be concluded that skull growth had no effect on the angle of insertion. An optimal insertion of 270\u2013360\u00b0 would suffice for successful outcome compared to deeper insertion (&gt;360\u00b0).<\/jats:p>","DOI":"10.1159\/000549512","type":"journal-article","created":{"date-parts":[[2025,12,8]],"date-time":"2025-12-08T17:01:28Z","timestamp":1765213288000},"page":"1-12","source":"Crossref","is-referenced-by-count":0,"title":["Temporal Bone Changes in the Angle of Insertion after Cochlear Implantation and Its Effects on Outcome: Unlocking the Controversy"],"prefix":"10.1159","author":[{"given":"M.
