Posterior Laryngeal Cleft - Anaesthetic Experiences

¹ Department of Anaesthesia, The Hospital for Sick Children, University of Toronto, Toronto, Ontario
² The Hospital for Sick Children, University of Toronto, Toronto, Ontario

Two cases of congenital posterior laryngeal cleft are reported which typify the anaesthetic techniques used for operation on this defect at The Hospital for Sick Children, Toronto. Although this anomaly of the airway is rare, it is potentially curable by surgery and should be included in the differential diagnosis of neonatal respiratory distress aggravated by feeding.

The anaesthetic technique used for microlaryngeal surgery consisted of topical lidocaine, insufflation of oxygen and halothane with supplementary methoxyflurane and spontaneous ventilation. A nasotracheal tube is left in situ postoperatively until laryngeal oedema has subsided. The literature is reviewed and the relevant anaesthetic experience over a ten-year period at The Hospital for Sick Children, Toronto, is summarized.
