The Effect of Low-Level Laser Therapy (LLLT) for Treatment of Bilateral Vocal Cord Paralysis Secondary to Lithium Battery Ingestion; a Case Report

Bilateral vocal cord paralysis is one of the most dangerous electrochemical burns caused by lithium battery ingestion, especially in children. Current treatments usually include immediate battery removal to a range of conservative management techniques and invasive procedures, including tracheostomy, unilateral posterior cordotomy, thoracotomy, and other surgical procedures. This study reports a two-year-old girl with laryngeal electrochemical tissue burn and bilateral vocal cord paralysis due to lithium battery ingestion. She was treated by low-level laser therapy (LLLT) by TecmLP200, for Red Light Laser (650 nm) and Infrared Laser (810nm100 mw) on necks acupoint and some other points. The use of LLLT has been quite successful in treating the effects of ingestion of lithium battery on bilateral paralysis of the vocal cords. This therapeutic modality may be more effective, non-invasive, uncomplicated, tolerable, and affordable.
