title: [Etiology of laryngeal stridor in neonates: analysis of 16 cases].
abstract: OBJECTIVE
  To reduce misdiagnosis and explore etiology of laryngeal stridor in neonates.
  
  
  METHODS
  Sixteen neonates with laryngeal stridor were reviewed. All the patients were examined with CT scan for larynx and lungs and some were examined with laryngoscopy. Laboratory examination and chromosome analysis were also done in all or some patients.
  
  
  RESULTS
  All the 16 neonates were diagnosed before admission as congenital simple laryngeal stridor in other hospitals. Of the 16 neonates with laryngeal stridor, 5 (31%) had thyroglossal ductal cyst, 1 (6%) neonate with cri du chat (5p(-)) syndrome, 2 (13%) neonates with Pierre-Robin syndrome and the rest 8 (50%) were suspected of congenital simple laryngeal stridor.
  
  
  CONCLUSIONS
  Neonates with laryngeal stridor are easily misdiagnosed; neonatal thyroglossal duct cyst is one of common causes. The diagnosis for a congenital simple laryngeal stridor should be carefully made excluding the possibility of related diseases. The authors recommend that laryngoscopy and CT scan for larynx should be performed in the neonates with laryngeal stridor.
