Poorly regulated activity of the perilaryngeal muscles affects phonatory function and contributes to a class of disorders known as hyperfunctional or musculoskeletal tension voice disorders. Recognizing the signs and symptoms of excess or dysregulated laryngeal muscle activity is critical to proper diagnosis and selection of appropriate treatment(s). Although numerous approaches exist to manage such hyperfunctional syndromes, manual circumlaryngeal techniques have recently received attention as valuable tools in both assessment and treatment. Therefore, the purpose of this article is to: (1) describe common phenomenological features of dysregulated laryngeal muscle tension, thereby facilitating its recognition, (2) highlight the role of manual circumlaryngeal techniques in assessment and management, (3) survey additional treatment approaches for laryngeal hyperfunction, and explore the evidence to support their effectiveness, and (4) identify unresolved issues and controversies surrounding tension-based voice disorders.
