Pediatric Dysphagia Outcomes After Injection Laryngoplasty for Type I Laryngeal Cleft

Dysphagia with aspiration is a common disorder in the pediatric population. Aspiration with
feeds is diagnosed on modified barium swallow studies and patients are referred to the
pediatric otolaryngologist to assess the airway for a possible laryngeal cleft. Type I
laryngeal cleft can lead to dysphagia and aspiration in young children. However, diagnosis
of type I laryngeal cleft can be difficult and subjective at microlaryngoscopy in the
operating room. Type I laryngeal cleft evaluation and treatment in the pediatric population
is an emerging science. The largest published series of pediatric patients with type I
laryngeal clefts shows conflicting evidence in terms of outcomes, resolution of dysphagia
and method of treatment. It is generally recommended to do an injection laryngoplasty at the
time of airway evaluation as a diagnostic and therapeutic measure. Improvement in symptoms
supports the diagnosis and can serve as either definitive treatment with repeated injections
or as a preemptive treatment in preparation for surgical repair. A comparison of quality of
life outcomes before and after injection laryngoplasty has not been carried out. Thus, the
aim of this study is to determine if injection laryngoplasty improves symptoms and quality
of life related to dysphagia in a pediatric population with laryngeal clefts.
