Overview
Inducible laryngeal obstruction (ILO) encompasses conditions causing intermittent airway obstruction, including paradoxical vocal fold movement and irritant-induced laryngeal spasm, leading to symptoms like stridor and dyspnea 3.Diagnosis
Clinical history and symptoms (hoarseness, stridor, dyspnea) are crucial 3.
Point-of-care airway ultrasonography can help assess laryngeal masses and rule out certain interventions like cricothyroidotomy 2.
Distinguishing from other causes like laryngomalacia may require interdisciplinary evaluation 3.Management
Speech and language therapy interventions guided by behavior change techniques are emerging as a potential first-line approach 1.
Specific drug treatments are not detailed in the provided abstracts.
In severe cases, emergency interventions such as tracheostomy may be necessary if airway compromise is imminent 2.Special Populations
No specific guidance provided for pregnancy, pediatrics, or elderly populations in the given abstracts.
Comorbidities may influence management complexity but are not explicitly addressed 3.Key Recommendations
Utilize behavior change techniques informed by systematic literature reviews and clinical practice to develop speech and language therapy interventions for ILO (Evidence: Moderate 1).
Consider point-of-care airway ultrasonography to assess laryngeal structures and guide emergency airway management decisions (Evidence: Weak 2).
Employ interdisciplinary approaches for accurate diagnosis, distinguishing ILO from other laryngeal disorders like laryngomalacia (Evidence: Expert opinion 3).References
