Introduction
Singer's Laryngeal Dystonia (SLD) is a rare form of dystonia considered a subtype of both Laryngeal Dystonia (LD) and musician’s dystonia. It affects professional singers and has symptoms characteristic of either adductor/ADLD or abductor/ABLD occurring selectively during singing. SLD is a "task specific" type of dystonia affecting the singing voice and was only recently classified in the literature (Simonyan et al., 2021.) The most common symptom is a reproducible instability which disrupts vibrato/tone quality, is resistant to vocal exercises, and independent of vocal fatigue. It is separately identifiable from easily recognizable and treatable technical problems, which may arise from the singer desperately trying to stabilize the voice (Halstead et al., 2015.)

Research/Literature Review
Research on this rare form of dystonia is limited. Halstead et al (2015) compared the profiles of four patients with SLD who presented with task/pitch specific types of dystonia in singing. As in cases of LD that affect speech, the most common type of therapies/treatment is management of symptoms. The standard of LD care has largely been limited to Botox injections (Simonyan et al., 2021) but conventional dystonia treatments rarely offer adequate relief in task-specific dystonia (Sadnicka et al., 2017.) Anecdotally, treatment for SLD in the clinic/studio involves "working around" the problem. Though not curative, behavioral approaches can offer practical tools that help singers manage symptoms and sustain their vocal careers with/without medical treatment. Singing teachers and speech pathologists have acquired experience/background that may inform treatment and benefit the singer with SLD. Ideal care team includes the speech pathologist and singing voice specialist to effectively manage the unique and more subtle demands of the patient.

Objective
This poster presentation seeks to give an overview of SLD, define symptomatology, diagnostic criteria, and treatment considerations for singers. It will discuss care with and without botulinum toxin injections and highlight cumulative case study data from the literature.

Conclusion
Further studies are needed to deepen our understanding of SLD and to develop more accurate diagnostic tools and effective treatment options for those affected by it and the professionals who treat them.
