Laryngeal Electromyography guided Vocal Fold Injections-Spain Experiences
喉肌電圖導引聲帶注射-西班牙經驗
Acute recurrent laryngeal neuropathy (RLN) presents significant challenges in clinical management, often resulting in compromised vocal function and airway protection. One promising therapeutic approach involves laryngeal electromyography (LEMG)-guided hyaluronic acid (HA) vocal fold (VF) injections. This technique aims to address the symptomatic glottal gap associated with acute laryngeal paralysis (ALP), a common consequence of RLN. EMG guidance ensures precise delivery of HA into the affected laryngeal muscles, enhancing vocal fold closure and reducing the glottal gap, thereby improving phonation and preventing aspiration. The HA acts as a temporary filler, providing structural support to the vocal folds while potentially promoting intrinsic healing mechanisms. Preliminary studies suggest that this method is minimally invasive and can be performed in an outpatient setting, offering significant advantages over more invasive surgical options. Additionally, the use of EMG ensures that the injections are accurately placed, optimizing the therapeutic outcomes and minimizing the risk of complications. This innovative approach holds promise for improving the quality of life for patients suffering from RLN and ALP, representing a significant advancement in the field of laryngology. Further research is needed to validate long-term efficacy and safety, as well as to refine the technique for broader clinical application.
