Abstract
Objectives
Deep interarytenoid notch (DIN) is a congenital variation of the larynx often associated with dysphagia and aspiration (DA) in young children. Feeding therapy with thickeners and surgical management with injection larygoplasty (IL) are used with various efficacies. Thickeners address the functional domain and IL addresses the anatomical domain of treatment. Our objective was to evaluate DIN patients managed with both interventions.
Methods
We conducted a retrospective pilot descriptive study of DIN patients with DA aged 1-3 years receiving thickeners and IL. Patients received a systematic weekly reduction of thickeners, referred to as the Thickener Weaning Protocol (TWP), based on clinical signs and symptoms of DA. The outcomes were assessed by the rate of thickener level reduction and DA-related sign/symptom frequency achieved at 6 months post-treatment.
Results
Thirteen patients with DIN associated DA were analyzed. The TWP was initiated within 2 months in 77% of patients, and within 4 months in 100% of patients. Thickener scores improved from an average of 5.76 (3/4 honey) to 2.15 (thin) (p = 0.001). DA-related signs/symptoms frequency improved from an average of 3.3 to 0.84 (p = 0.05).
Conclusions
These findings suggest that treatment of DIN associated DA with a combination of thickeners and IL results in significant clinical improvements in young children.
