Margins of partial cricotracheal resection in children.
OBJECTIVE
To review the surgical margins of partial cricotracheal resection in our series of patients. This includes specific anatomic detail as to each superior and inferior resection margin. To apply this information and access the utility of partial cricotracheal resection for the treatment of subglottic stenosis.


METHODS
A retrospective review was performed of 38 children with severe subglottic stenosis who underwent partial cricotracheal resection. Information was obtained with regard to the specific anatomic location of the superior and inferior resection margins, the grade of subglottic stenosis preoperatively, the type of stenting material used postoperatively, and other surgical details specific to each procedure.


RESULTS
The superior resection margins were generally to the superior aspect of the cricoid cartilage but as high as the undersurface of the true vocal folds in a minority of patients. Inferior resection margins were generally to the second tracheal ring. Length of resection varied, but was as long as 3.0 cm in one patient. Overall surgical success based on decannulation was > 86%.


CONCLUSIONS
Partial cricotracheal resection is a safe and successful procedure for the treatment of subglottic stenosis. The margins and length of resection should be tailored specifically for each patient; and special considerations must be taken when extensive resection to the level of the true vocal folds is required. Safe airway management in the postoperative period is essential.
