Transoral Laser Excision of a Pyriform Sinus Cyst

Pyriform sinus cyst is a rare disease. This disease can be found by chance or appear as lymph nodes with cancer, infections, shortness of breath, or airway compromise, and can be an unusual cause of dysphonia. This paper presents a case of a pyriform sinus cyst in the pharyngeal wall of the left pyriform sinus, which presented as neck discomfort in a 63-year-old female. The plan was to remove this cyst with a transoral CO₂ laser because a CO₂ laser is a useful tool for removing cysts without bleeding and consuming time. The excision was performed successfully. Transoral laser pyriform sinus cyst excision is a simple, safe, and effective method for the treatment of pyriform sinus cysts. This procedure is likely to be used as a selective treatment when managing this condition.
