• Clinical strategies for spastic/spasmodic dysphonia center on recurrent laryngeal nerve (RLN) interventions—crush, section—and associated histopathology, with studies predicting and evaluating postoperative voice outcomes to guide surgical decisions. [2] [12] [14] [13] [8]

• Psychogenic and anxiety-related voice disorders are addressed through theoretical models of speech anxiety, case-based hysterical aphonia, psychiatric-voice correlations, and behavioral therapy/desensitization techniques. [5] [15] [16] [17] [20]

• Methodological and diagnostic voice science emphasizes objective measures and articulatory theory to phenotype disorders, using S/Z ratio, speaking fundamental frequency, distinctive-feature analyses, and speech-reaction time metrics. [19] [6] [4] [7] [1]

• Clinical phenomenology of diverse dysphonias and related conditions—spasmodic dysphonia, Shy-Drager-related vocal cord issues, organic disorders, and hysterical/psychogenic cases—document descriptive presentations and clinical implications. [10] [9] [15] [11]

• Foundational and theory-informed clinical approaches to articulation and voice therapy underpin practice, illustrating early integration of phoniatrics principles, distinctive-feature theory, and therapy-oriented frameworks. [4] [1]
