Laryngopyocele with a report of three cases.

Laryngoceles are classified into three types: internal, external or combined. If complicated with infection, laryngopyocele develops, often with dramatic symptoms. Three cases of laryngopyocele are reported. Aetiology, symptomatology and treatment are discussed. It is recommended that all laryngoceles producing symptoms be removed through an external incision and, if necessary through a laryngofissure.
