Comparative Results of Vocal Fold Injury According to the Fiber-Based Laser in a Rabbit Vocal Fold Model.

Objectives: We assessed the safety of flexible fiber-based lasers including the potassium-titanyl-phosphate (KTP), CO, and Holmium lasers using a rabbit vocal fold model and provided the safety evidence of laser before human clinical trial.

Methods: In all, 120 male New Zealand white rabbits were used. Each laser was used to induce acute and chronic vocal fold injuries in 40 rabbits.

Analysis of Prognostic Factors in Malignant External Otitis.

Objectives: Malignant external otitis (MEO) is a potentially fatal infection of the external auditory canal, temporal bone, and skull base. Despite treatment with modern antibiotics, MEO can lead to skull base osteomyelitis. Until now, there have been few studies on the prognostic factors of MEO.

Persistent Vocal Fold Granuloma Following Superficial PAAG Injection Laryngoplasty: A Case Report.

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.
