title: Adverse Reaction to Hyaluronic Acid Injection Laryngoplasty: A Case Report.
abstract: BACKGROUND
  Injection laryngoplasty using hyaluronic acid is a safe procedure commonly performed on patients with glottic insufficiency.
  
  
  METHODS
  This is a descriptive study of a case of adverse reaction to hyaluronic acid in a patient who underwent injection laryngoplasty for the treatment of unilateral vocal cord paralysis.
  
  
  CONCLUSIONS
  The patient was treated with antibiotics and corticosteroids and had a full recovery. The authors recommend close observation following injection laryngoplasty using hyaluronic acid and diligent investigation of persistent postoperative laryngopharyngeal symptoms.
