近紅外光透過保護螺旋神經節神經元維護動物植入式人工耳蝸手術後的殘餘聽力

// Near-infrared light protects residual hearing by preserving spiral ganglion neurons in an animal Model of CI Surgery

本研究探討近紅外線（NIR）光療對豚鼠人工耳蝸手術中聽力保護的效果｜NIR照射能顯著減少聽力損失並防止螺旋神經節神經元流失，尤其是在基底耳蝸區域｜絲帶突觸數量未受人工耳蝸或NIR影響，顯示NIR具有重要神經保護作用，有助於維持殘餘聽力及提升植入效果。

// This study investigated the protective effects of near-infrared (NIR) light treatment on hearing preservation during cochlear implant (CI) surgery in guinea pigs. NIR irradiation prior to CI electrode insertion significantly reduced hearing loss and prevented spiral ganglion neuron (SGN) loss, particularly in the basal cochlea. Ribbon synapse numbers were unaffected by the implant or NIR treatment. The results suggest NIR offers neuroprotection critical for preserving residual hearing and supporting CI function.
