vallecular cyst
Benign cyst occurring in the vallecula between the epiglottis and tongue base. Can cause dysphagia or airway obstruction.
Full Definition
A vallecular cyst is a benign, fluid-filled sac that develops in the vallecula, the anatomical space between the epiglottis and the base of the tongue. These cysts are typically lined with squamous or respiratory epithelium and can present with symptoms ranging from mild throat discomfort to severe dysphagia and potential airway compromise. In head and neck oncology practice, vallecular cysts must be differentiated from malignant lesions through imaging and direct laryngoscopy. Treatment usually involves surgical excision via endoscopic or open approaches, depending on size and location.
Usage
Usage note: Often confused with vallecular carcinoma; emphasize benign nature in patient materials.
