Key Points

This analysis aims to evaluate the outcomes of laryngotracheal separation and tracheoesophageal diversion in children with intractable aspiration.
Retrospective review of 42 patients who underwent surgery from 2002 to 2023.
Patients selected for either laryngotracheal separation or tracheoesophageal diversion based on age and tracheostomy status.
Follow-up duration ranged from 2 months to over 21 years.
No fatal complications from tracheobronchial fistula observed in any patient.
Postoperative complications included formation of fistulas and granulation tissue, but no major life-threatening issues reported.
The majority of patients showed improved quality of life and survival rates over long-term follow-up, with 28.6% tracked for over 10 years.

Retrospective analysis finds laryngotracheal separation improves outcomes in pediatric patients with aspiration, highlighting its safety.
