Objective  To identify risk factors for operation-specific outcomes of pediatric cricotracheal resection (CTR).

Design  We identified the first 100 consecutive children undergoing CTR at our institution from January 1, 1993, to December 31, 2004. Retrospective review of medical records provided data on demographics, operation dates, decannulation dates, and proposed risk factors, including age, stenosis grade, vocal cord function, Down syndrome, history of distal tracheal surgery, history of open laryngotracheal surgery, presence of tracheotomy at the time of operation, use of suprahyoid release, extended CTR, and use of chin-to-chest sutures. Complete data sets were available for 93 patients. We performed multivariable logistic regression analysis to identify significant independent risk factors.

Setting  A tertiary care children’s hospital.

Patients  All patients younger than 18 years who underwent CTR at our institution.

Main Outcome Measures  Operation-specific and overall decannulation rates.

Results  Results of the preoperative evaluation showed grade III or IV stenosis in 89 patients (96%). The overall decannulation rate included 87 patients (94%); the operation-specific decannulation rate, 66 patients (71%). The only significant risk factor for failure to decannulate after 1 operation was the presence of unilateral or bilateral vocal cord paralysis (P = .007).

Conclusions  Cricotraceal resection may be safely performed in patients with multiple airway lesions. Patients with a history of vocal cord paralysis who undergo CTR often require more than 1 open airway procedure for decannulation and should be counseled appropriately. This study represents the largest reported series of pediatric CTR.
