Laryngeal edema

Laryngeal edema is an abnormal accumulation of interstitial fluid within the mucosal and submucosal tissues of the larynx, representing a potentially life-threatening upper airway emergency It affects pediatric and adult populations across various clinical settings, most frequently triggered by mechanical trauma such as endotracheal intubation, acute type I hypersensitivity reactions, hereditary or acquired angioedema, local infections, or inhalation injury

It affects pediatric and adult populations across various clinical settings, most frequently triggered by mechanical trauma such as endotracheal intubation, acute type I hypersensitivity reactions, hereditary or acquired angioedema, local infections, or inhalation injury This swelling significantly narrows the glottic and subglottic lumen, leading to characteristic signs of upper airway obstruction, including dysphonia, inspiratory stridor, progressive dyspnea, and critical respiratory compromis...
