Management of laryngeal cleft in mechanically ventilated children with severe comorbidities.

Laryngeal clefts are rare congenital malformations of the posterior part of the larynx. The severities are correlated with the downward extension of the cleft and can involve numerous clinical symptoms including dysphagia and respiratory distress. As significant comorbidities may be present, individual treatments depend on the child's general condition and type of cleft involved. Herein, we describe two cases of children with laryngeal clefts and severe comorbidities requiring mechanical ventilation. One child with type III laryngeal cleft was successfully managed with the lateral pharyngotomy approach. The other child with type II laryngeal cleft has not been able to undergo cleft-closure surgery because of severe general conditions, therefore has continued training for feeding and swallowing.
