Views of larynx by flexible laryngoscopy. (A) Initial flexible laryngoscopy revealed no vocal fold lesions, edema, or evidence of impaired true vocal fold (TVF) mobility. (B) Laryngoscopy exhibited severe supraglottic edema and hypomobility of the left TVF, clinically consistent with angioedema. (C) Laryngoscopy at follow-up visit demonstrated resolution of edema, erythema, and no residual impairment of vocal fold mobility.

The true vocal folds were mobile bilaterally with no laryngeal lesions ( Figure 1A ). Otolaryngology performed flexible indirect laryngoscopy which demonstrated significant edema of the supraglottis, consistent with angioedema, along with impaired mobility of the left true vocal fold (TVF;  Figure 1B ). Flexible laryngoscopy and stroboscopy confirmed normal TVF mobility and complete resolution of laryngeal edema and erythema ( Figure 1C ).
