Injection medialization laryngoplasty is a procedure that has many advantages in treating vocal fold paralysis; however, undesired complications can occur. We experienced a case of a pulmonary embolism, suspected in a patient who had undergone an injection laryngoplasty with calcium hydroxylapatite (CaHA). The patient suffered dyspnea after undergoing the injection laryngoplasty. Chest embolism computed tomography (CT) scan revealed a new lesion of enhancing materials at the pulmonary vasculature in the right upper lobe. The CaHA embolism was suspected, and the patient was treated with warfarin for 12 months. The patient's symptom of dyspnea nearly disappeared and a follow up chest embolism CT scan revealed no signs of the previous lesion. Thus, we would like to report this rare case along with a review of the literature.
注射式喉内移术在治疗声带麻痹方面有诸多优势；然而，也可能出现不良并发症。我们遇到一例肺栓塞病例，该病例疑似发生在一名接受羟基磷灰石（CaHA）注射式喉成形术的患者身上。该患者在接受注射式喉成形术后出现呼吸困难。胸部栓塞计算机断层扫描（CT）显示右上叶肺血管处有一个新的强化物质病变。怀疑是CaHA栓塞，该患者接受了12个月的华法林治疗。患者的呼吸困难症状几乎消失，后续胸部栓塞CT扫描未发现先前病变的迹象。因此，我们想报告这一罕见病例并对相关文献进行综述。
