Abstract
Three cases of delayed decannulation in infant were reported and discussed. A one year and three months old boy who had been troubled for one month by delayed decannulation. In this case, a special short cannula (Fig.) was successfully used for purpose of the maintenance of normal air passage. The stimulation to the trachea and the bend of tracheal cartilage are avoidable by using this cannula.
In other two cases, eleven months old boy and two years old boy, delayed decannulation was cured by removing tracheostoma to the suitable position.
Delayed decannulation occurs easily in infants because of their narrow air passage. The subsidence of tracheal cartilage and the presence of granulation tissue in the trachea make the air passage narrower. Therefore, it is important to avoid the above mentioned factors.
