Abstract
Glottic closure is essential for vocalization and airway protection. Several pathological conditions cause glottic insufficiency, such as vocal fold paralysis and presbylarynx, which is the age-related atrophy of laryngeal muscle. Injection laryngoplasty is common technique to treat glottic insufficiency, because it can be easily and inexpensively performed in an outpatient setting. Different injection material should be selected according to the purpose and patient condition before the procedure. Ideal material for injection laryngoplasty must be biocompatible, and the injected volume should be maintained for the desired duration without migration. Further, it will be better if it could be easily injected and removed. In this article, we reviewed the published research related to material for the injection laryngoplasty and tried to think about the limitations of current studies and the future direction of treatment.
