Left mixed laryngocele in absence of risk factors: A case report and review of literature.

Laryngocele is an uncommon benign cystic dilatation of the laryngeal saccule that communicates with the laryngeal lumen and contains air. On the basis of its localization, it can be traditionally classified in internal, external, or mixed. Usually unilateral and rarely bilateral, it may be congenital or acquired. It most often appears later in life without important symptoms except for cervical swelling. Here, together with a review of literature, we report the case of a 72-year-old man, smoker but without other specific risk factors, who presented laryngeal dyspnea for about one year. Neck CT scan performed during a previous hospitalization for respiratory failure revealed a left mixed laryngocele that was later surgically removed with cervicotomic access. The patient was discharged after one week. One month after surgery, we confirmed the absence of disease with video laryngoscopy.
