This study aims to report a cochlear-implanted case who was explanted due to recalcitrant pain at the site of the device, despite various manage- ment trials. After explantation, this patient had an unexpected subjective and objective improvements in hearing. The patient reported improved hearing after explantation and was satisfied with using hearing aids. The audiological evaluation of the patient showed not only preserved hear- ing but also an unexpected hearing improvement. The medical records of the patient were reviewed to retrieve all the relevant data. This case illustrates how pain after cochlear implantation can be severe enough to discourage the patient from undergoing re-implantation. It also shows an unexpected hearing improvement after explantation. Although a human error in audiological evaluation can be the first and most simple possible explanation for this finding, the objective improvement of the patient is highly suggestive of a real hearing improvement. It can be hypothesized that the mechanical or electrical stimulation by the cochlear implant could have led to this hearing improvement.
本研究旨在报告一例因设备部位顽固性疼痛而取出的人工耳蜗植入病例，尽管进行了各种管理尝试。取出后，该患者的听力在主观和客观上都出现了意外的改善。患者报告说取出后听力有所改善，并对使用助听器感到满意。患者的听力学评估不仅显示听力保存，而且还出现了意想不到的听力改善。回顾患者的病历以检索所有相关数据。本病例说明了人工耳蜗植入后疼痛可能严重到足以使患者不愿接受再次植入。它还显示了取出后听力的意外改善。虽然听力评估中的人为错误可能是对这一发现的第一个也是最简单的可能解释，但患者的客观改善高度提示听力的真实改善。可以假设人工耳蜗的机械或电刺激导致了这种听力改善。
