title: Persistent Vocal Fold Granuloma Following Superficial PAAG Injection Laryngoplasty: A Case Report.
abstract: The injection material polyacrylamide hydrogel (PAAG; Ferrosan, Søborg, Denmark) is often used as space filler for soft-tissue defects. PAAG is a suitable alternative to the materials used for injection laryngoplasty. Over the past decade, 427 patients have undergone injection laryngoplasty in our clinic using PAAG, and no major complications, such as material migration or foreign body granuloma, were identified. Here, we report the case of the first woman to undergo laryngomicrosurgery to remove a vocal fold granuloma that developed after a superficial injection laryngoplasty performed 4 years previously.
