dc.description.abstractBACKGROUND Deep Interarytenoid Notch (DIN) is the mildest form of laryngotracheoesophageal cleft defect and is frequently found in young children with dysphagia and aspiration. Treatment guidelines are not defined. Injection laryngoplasty (IL) is a surgical procedure injecting polymer gel into the issue around the defect. Our objective was to evaluate the efficacy of IL in pediatric populations with severe dysphagia and aspiration. METHODS We conducted a pilot retrospective chart review of DIN patients under 36 months who underwent IL at PCH. Severity of dysphagia before and after IL was measured using modified barium swallows (MBS) (scale 0‐10) and documented symptoms. Statistical analysis was done using paired two sample t‐test with a p value of 5 percent. RESULTS Patients with initial MBS above double honey (7) improved an average of 2.6 ±1.38 points while those with initial scores below 7 did not see a statistical change in MBS. At the end of the study period, the final MBS scores for both groups were statistically similar.CONCLUSIONS IL treatment for DIN associated dysphagia results in improvement of MBS scores and symptoms in toddlers with severe aspiration. Careful timing of IL impacts morbidity. Future prospective controlled studies are necessary to evaluate the role of IL and medical interventions in thickener wean and clinical improvement.
