Distraction Breathing Exercise in Managing Inducible Laryngeal Obstruction in a Female Patient

Inducible laryngeal obstruction (ILO) describes as inappropriate, episodic, reversible laryngeal closure during inspiration, occurring at the glottic and/or supraglottic level, in response to external triggers causing exertional breathing difficulties. We describe a case of a female patient with an underlying major depressive disorder who presented with sudden onset of stridor and tachypnoea, whereby the external trigger was psychogenic in origin. Bedside flexible nasopharyngolaryngoscopy (FNPLS) showed characteristic findings of paradoxical adduction of vocal cords during inspiration. Arterial blood gas analysis, routine blood tests, chest radiography, and computed tomography (CT) scan of brain, neck, and thorax excluded neurological or airway abnormality. Bedside distraction breathing exercise alleviated the stridor and tachypnoea. The patient was managed by supportive psychotherapy, speech therapy, and anti-reflux medication and was discharged well with resolution of her respiratory distress. We would like to highlight that meticulous history along with physical examinations are imperative especially amongst Otorhinolaryngologists as emergent airway management tracheostomy would have been unnecessary and cause more stress and burden to the patient as well as family members.
