Rates of Delayed Postcochlear Implant Pain in the Pediatric Population-Role of Proactive Approach.

OBJECTIVE:To investigate the rates of delayed postoperative cochlear implantation pain (DPCIP) in the pediatric population, using a "reach-out" proactive approach. Secondary aims included the possible impact of surgery extent or the patient ethnicity on DPCIP rates.MATERIALS AND METHODS:A cross-sectional study was conducted at Soroka University Medical Center in Israel. Demographics and data regarding the surgery and surgical complications were collected from the medical records of the patients. A telephone questionnaire was conducted for parents of all children who underwent cochlear implantation (CI) between 2007 and 2020. The questions addressed pain at four time periods: during hospitalization after surgery, 3 months, 2 years, and 5 years after surgery.RESULTS:Out of 213 patients, 129 (60%) were included in this study. The mean age was 41 months (±40). Unilateral CI was performed in 72 (56%) patients. At 3 months and 2 years after surgery, 8.5% of patients reported pain (visual analog scale [VAS] ≥ 1). Five years after surgery, a slight increase in the number of patients who reported pain (12%) was observed. Of those experiencing pain 2 years and 5 years after surgery, 10/12 (83%) and 11/16 (69%), respectively, reported a new onset of the pain. Surgery extent and cultural background were not significantly associated with DPCIP rates. No correlations were found between patients complaining of pain and any surgical complications.CONCLUSIONS:DPCIP rates may be underrecognized and higher than previously reported, reaching up to 12%. This long-term effect should be acknowledged and discussed with parents upon informed consent.
