Abstract
The case of a 53-year-old man complaining of dyspnea and swelling in the left submandibular region was reported. Laryngoscopic examination revealed a swelling of the left aryepiglottic fold and false fold. Cervical tomography and CT imaging showed an air-filled mass in his left, lateral neck, superior and lateral to the thyroid cartilage. Based on these findings, the diagnosis was established as the combined type of laryngocele. After a tracheotomy was done under local anesthesia, the laryngocele was totally removed by the external approach under general anesthesia.
It has been reported that laryngocele is derived from an enlargement of the laryngeal saccule located in the laryngeal ventricle, and that the incidence of laryngocele in Japan is very rare in comparison with that in Europe and the USA. We reviewed papers and discussed the etiology, diagnosis and treatment of this disease.
