Subglottic stenosis: another challenge for intubation and potential mechanism of airway obstruction in Pierre Robin Sequence.

OBJECTIVE

To determine the endotracheal tube (ETT) size and presence of subglottic narrowing in children less than 1 year old with Pierre Robin Sequence (PRS).

MATERIALS AND

METHODS

We performed a retrospective review from 2005 to 2009 of infants with PRS who underwent diagnostic laryngoscopy (DL) and intubation.

RESULTS

Fifteen children with a median age of 25 days were reviewed. All patients, except one, were born full term. Subglottic narrowing was visualized in 5 patients (33%). 73% of all patients required an ETT size smaller than what is recommended by intubation guidelines in the literature in regards to normative data based on age and weight.

CONCLUSION

Infants with PRS may have a higher incidence of subglottic stenosis and require a smaller ETT compared to the normal population. This pilot study warrants a larger prospective investigation to validate these findings.
