Carotid sinus syndrome (CSS) is a hypersensitivity of the carotid sinus manifested by atrioventricular sinus bradycardia or decreased arterial pressure of at least 50 mmHg. Triggering factors can be neck movements, shaving of the beard or too-tight collars. CSS can be rarely caused by the presence of malignant or benign masses in the head and neck area.
A 49 years-old white woman with a laterocervical mass presented recurrent episodes of sinus bradycardia related to head's rotation. Neck CT scan revealed a right piolaryngocele and internal left laryngocele. Episodes of bradycardia were disappeared after endolaryngeal carbon dioxide laser assisted marsupialization.
Laryngocele should be sought in the differential diagnosis of patients with bradycardia episodes due to carotid sinus compression. Surgical treatment of laryngoceles can lead to the termination of such episodes.
颈动脉窦综合征（CSS）是指颈动脉窦过敏，表现为房室结性心动过缓或动脉压至少下降50mmHg。触发因素可能是颈部运动、刮胡子或领口过紧。头颈部区域出现恶性或良性肿块很少会导致CSS。
一名49岁的白人女性，有颈侧肿块，出现与头部旋转相关的反复窦性心动过缓发作。颈部CT扫描显示右侧梨状窦囊肿和左侧喉内囊肿。经喉二氧化碳激光辅助袋形缝合术后，心动过缓发作消失。
对于因颈动脉窦受压导致心动过缓发作的患者进行鉴别诊断时，应考虑喉囊肿。喉囊肿的手术治疗可使此类发作终止。
