                • Secondary laryngocele: Obstruction of laryngeal ventricle causes internal or mixed laryngocele
                  • Most common obstructing lesion: Laryngeal SCCa

                • Mixed laryngocele: Paraglottic space internal laryngocele extends through thyrohyoid membrane into low submandibular space (SMS)
                • Pyolaryngocele: Secondary infection of any laryngocele
