Case of Adductor Spasmodic Dysphonia Patient Complaining of Voice Tremor and Hoarseness Treated with Combined Korean Medical Therapies

Background: Adductor spasmodic dysphonia (ASD) is caused by the involuntary contraction of laryngeal muscles due to dystonia localized to the larynx. In the case of ASD, conventional treatment is mainly performed with a botulinum toxin injection. However, the botulinum toxin injection has a short-lasting effect and requires repeated injections. Alternatives are needed due to concerns over adverse effects, such as general weakness and airway aspiration caused by the botulinum toxin injection.Case report: A 46-year-old female patient with ASD complained of voice tremor and hoarseness. The combined Korean medical treatments-Ukgan-san-gami, Jakyakgamcho-tang, acupuncture, and transcutaneous electrical nerve stimulation (TENS)-were administered on the first day the patient was hospitalized. The Voice Handicap Index (VHI) was evaluated during the treatment. The VHI taken on the second day totaled 92 points. On the ninth day, 81 points were recorded. Total score gradually improved, and on the 16th day, 62 points were recorded. Combined Korean medical treatment lasted 19 days.Conclusion: The present case report suggests that a combined Korean medical treatment approach with Ukgan-san-gami, Jakyakgamcho-tang, acupuncture, and TENS might be effective for symptoms such as voice tremors and hoarseness. Combined Korean medical treatment can be a therapeutic option for patients with ASD.
