[Laryngeal cysts in the newborn (9 cases) (author's transl)].

Nine cases of laryngeal cysts in the newborn were seen over a period of 8 years. After reviewing data from the literature, the authors emphasise treatment. Simple puncture aspiration was invariably followed by a recurrence. Marsupialisation or endoscopic resection was associated with 5 successful results. An external operative approach was necessary in 4 cases because of multiple recurrences. No tracheotomy was necessary.
