We experienced two rare cases with laryngeal cystic lesions (laryngocele and laryngeal cyst). In the first case, the laryngocele case was removed by laryngomicrosurgery using an oral approach under general anesthesia. In the second case, the magnetic resonance imaging demonstrated a dumbbell-type cyst with mucus widely extending from the laryngeal lumen to the neck through the thyroid cartilage...

A schwannoma of the larynx is a rare benign tumor that usually presents as a submucosal mass in the pyriform sinus and the aryepiglottic space, and this type of schwannoma constitutes a diagnostic and therapeutic challenge for otolaryngologists. We present here two cases of supraglottic schwannomas that were misdiagnosed as laryngoceles. Both were excised through a lateral thyrotomy approach wi...

A laryngopyocele forms when a laryngocele becomes infected and fills with mucopus. We report a case of an internal larngopyocele that presented as airway obstruction in a 34-year-old man; such a presenting sign is exceedingly rare. We also review the anatomy, etiology, and clinical course of the different types of laryngoceles.

The laryngocele is an abnormal cystic dilatation of the saccule or appendix of the laryngeal ventricle, filled with air and communicating with the lumen of the larynx. When the neck of the laryngocele is obstructed, it becomes filled with mucus of the glandular secretion and is changed to a laryngomucocele. When this lesion becomes infected, a laryngopyocele is formed. The laryngocele is fairly...
