Multidisciplinary aspects of pediatric cochlear implantation: anesthesiological considerations

Area of Science:

• Pediatric Anesthesiology
• Otolaryngology
• Neuroscience

Background:

• Early cochlear implantation (CI) is crucial for optimal auditory and language development during critical neuroplastic periods.
• Infants and young children present unique anesthetic challenges for CI procedures.
• Understanding anesthesia-related events is vital for safe and timely CI in this population.

Purpose of the Study:

• To retrospectively analyze anesthesia-related events in pediatric patients undergoing cochlear implantation.
• To focus on children under 18 months, a key neuroplastic window.
• To evaluate the safety and identify potential complications associated with anesthesia for pediatric CI.

Main Methods:

• Retrospective analysis of 175 children under 3 years who received CI between 2014-2024.
• Data collection included demographics, comorbidities, anesthetic techniques, and complications during audiological tests, imaging, and surgery.
• Subgroup analysis for patients implanted before 18 months.

Main Results:

• Anesthesia-related complications occurred in 8.1% of patients, most commonly laryngospasm during extubation (n=8), all resolved without reintubation.
• Difficult intubation occurred in 3 patients, primarily those with craniofacial anomalies.
• No complications were noted during diagnostic procedures, and no significant association was found between complication rates and age, ASA, or Mallampati scores.

Conclusions:

• Cochlear implantation in infants, including those under one year, is safe when managed by experienced teams with appropriate anesthesia protocols.
• Anesthesia-related complications are rare and generally manageable.
• Recognizing and mitigating anesthesia risks supports timely CI interventions within the critical neuroplastic window, reassuring parents.
