Complications of Injection Laryngoplasty

Injection laryngoplasty (IL), commonly used to treat unilateral vocal cord paralysis, aims to improve glottic insufficiency, while preventing aspiration and enhancing voice quality by injecting material into the vocal cords. Moreover, recent advancements in endoscopic technology and biomaterials facilitated this procedure in the office setting under local anesthesia. IL is generally considered a safe procedure due to its minimally invasive nature. However, as clinical cases increase, reports of various complications associated with IL are also on the rise. These complications are typically not serious and they improve spontaneously with follow-up. However, they can often lead to serious issues affecting the patient’s safety and function, requiring active treatment or management. In this article, we will review possible complications that may arise during and after IL.
