Abstract :
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.
Case Report:
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.
Conclusion:
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.
