Eligibility
Inclusion criteria
Inclusion criteria: Pediatric patients strictly under the age of 5 years. A confirmed audiological diagnosis of severe-to-profound sensorineural hearing loss (SNHL), defined by a Pure Tone Average (PTA) exceeding 80 dB. Radiological or intraoperative confirmation of intracochlear fibrosis, specifically limited to Grades 1 and 2. Patients with no history of prior cochlear surgery or evidence of total cochlear ossification.
Exclusion criteria
Exclusion criteria: Any presence of structural cochlear malformations, such as Mondini dysplasia, which would alter standard insertion mechanics. Diagnoses of syndromic hearing loss (e.g., Usher syndrome) to prevent phenotypic confounding.
