The rate, causes and prognosis of dysphonia after anterior cervical approach (ACA) were investigated in our clinical series. During a 10-year interval, 235 consecutive patients with cervical disc disease underwent surgical treatment using anterior approach. Retrospective chart reviews showed recurrent laryngeal nerve (RLN) injury in 3 (1.27%) patients. All three patients were men and only one patient had multilevel surgery. These patients had RLN injury after virgin surgery. Laryngoscopic examination demonstrated unilateral vocal cord paralysis in all patients who had postoperative dysphonia. No permanent dysphonia was observed in our series and patients recovered after a mean of 2 months (range 1-3 months) duration. Dysphonia after ACA was a rare complication in our clinical series. Pressure on RLN or retraction may result in temporary dysphonia.
我们在临床系列研究中调查了颈椎前路手术（ACA）后声音嘶哑的发生率、原因及预后。在10年期间，235例连续的颈椎间盘疾病患者接受了前路手术治疗。回顾性病历审查显示，3例（1.27%）患者出现喉返神经（RLN）损伤。所有3例患者均为男性，只有1例患者接受了多节段手术。这些患者在初次手术后出现RLN损伤。喉镜检查显示，所有术后声音嘶哑的患者均出现单侧声带麻痹。在我们的系列研究中未观察到永久性声音嘶哑，患者平均在2个月（范围1 - 3个月）后恢复。在我们的临床系列中，ACA后声音嘶哑是一种罕见的并发症。RLN受压或牵拉可能导致暂时性声音嘶哑。
