Laryngocele is an air-filled cyst due to expansion of the anterior portion of the ventricle and saccule between the true and false cords. It may be congenital or acquired due to ventricular malignancy. It may be internal (within the thyroid cartilage) or external as it dissects out side the thyroid cartilage in the neck.
It presents with hoarseness, stridor and pain if infected. Examination will reveal soft, compressible mass at the lateral side of the neck which increases on coughing, while laryngoscopy will reveal smooth bulging or mass in the ventricle.
Treatment is by excision either endoscopically or by external approach.
