    Clinical Policy: Voice Therapy Reference Number: HNCA.CP.MP.134 Effective Date: 4/10 Coding Implications Last Review Date: 02/21 Revision Log See Important Reminder at the end of this policy for important regulatory and legal information. Description Voice therapy refers to any non-surgical techniques employed in the management of individuals with voice disorders. The goal is to modify vocal behaviors to reduce or correct maladaptive and inappropriate vocal behaviors and laryngeal trauma. Voice therapy is usually subject to speech therapy benefits. Policy/Criteria I. It is the policy of Health Net of California that voice therapy is medically necessary when provided by a qualified speech language pathologist for the following indications: A. Post vocal cord surgery or vocal cord trauma, or B. Post laryngeal (glottic) carcinoma, or C. Paradoxical vocal cord motion, or D. Functional or spastic (spasmodic) dysphonia, or E. Vocal cord nodules/lesions, or F. Vocal cord paralysis, or G. As part of gender affirming services. II. It is the policy of Health Net of California that voice therapy is not medically necessary to improve voice quality due to such conditions as laryngitis or for occupational or recreational purposes. Background Voice disorders are characterized by pitch, loudness, resonance, quality or duration of voice or by the inability to use one’s voice. The disorders result from abnormal laryngeal, respiratory or vocal tract functioning. Voice therapy includes four major components: vocal hygiene, vocal production, muscle relaxation and respiratory support. Disorders of the vocal cords such as surgical procedures, trauma, cancer, nodules and issues regarding motility (spasm, paralysis) can all affect speech.

It is characterized by vocal quality tensaestrangulada, harshly and / or interspersed with abrupt vocal attack and a great tension in the vocal tract. The etiology of spasmodic dysphonia is unclear. Some authors point to psychogenic causes, neurological or even unknown. Objective: To assess the prevalence of muscular dystonias and other neurological symptoms in patients with ED. Method: A retrospective study of 10 cases with diagnosis of ED for symptoms and neurological disorders associated. Results: There was a significant predominance of the disease in females (9:1). The average age of onset of symptoms was 32 years, ranging between 14 and 60 years. The mean disease duration was 10 years. Among the patients, 87.5% had a diagnosis of disorders of movement made by a neurologist, including orofacial dystonias (50%), essential tremor (50%) and spastic paraparesis (12%).

  • Spasmodic Dysphonia and Related Voice Conditions During COVID-19
    What do I need to know having spasmodic dysphonia or a related voice condition during the COVID-19 pandemic? By Christie DeLuca, MS CCC-SLP Speech Language Pathologist, Clinical Voice Specialist You may be in one (or all) of the following situations: Your botulinum toxin (Botox) injection has been cancelled or indefinitely postponed and symptoms are getting more significant; you are being forced to work remotely which means more phone calls and virtual meetings leading to vocal fatigue, a strained voice, and difficulty being heard, having a smooth voice or projecting effectively; you are dealing with more stress and anxiety during this time which is making your voice symptoms worse; you are worried that having spasmodic dysphonia makes you more at risk if you were to develop COVID-19. Let’s hopefully tackle some of these issues with some pertinent information. 1. You are worried that having spasmodic dysphonia makes you more at risk if you were to develop COVID-19 COVID-19 does NOT make you more susceptible to developing COVID-19. Further, if you are to develop COVID-19, having spasmodic dysphonia does not put you at greater risk. Spasmodic dysphonia, tremor and muscle tension dysphonia are not disorders that compromise your airway or respiratory system. Some with spasmodic dysphonia (particularly those with AB, those with AD up to 3 weeks after a botulinum toxin injection) or essential tremor of the voice may experience shortness of breath when speaking. However, this related to the valving of air at the level of your vocal folds and not related to a respiratory disorder.

Histologic examination revealed average muscle fiber diameters ranging from 21 to5711m. Botulinum toxin treat­ ment-related muscle atrophy was observed up to 5 months after injection. Endomysial fibrosis was present in all samples. His­ tochemical analysis in8patients revealed type 2fiber predominance in7 patients and fiber type grouping in2.Type-specific muscle fiber size changes were notpresent. Nerve samples were examined in plastic sections. In 8 patients the nerves contained homoge­ neous, large-diameter myelinated nerve fibers and sparse small fibers. One patient had a relatively increased proportion of small myelinated nerve fibers. Overall, the nerve fiber diameter was slightly larger inpatients than incontrols.

Abstract Background: Spasmodic dysphonia (SD) is often assessed and treated in a rather mono-dimensional way, despite knowledge of the impact of SD on a person’s quality of life. This study investigates how adults with SD think and feel about their speech, and cope with their voice problem. Methods: Adults with SD were asked to fill out the Behavior Assessment Battery’s (BAB-Voice) self-report tests. The Speech Situation Checklist-Emotional Reaction and Speech Disruption investigate negative emotional reaction and voice problems in particular speech situations.

  • Spasmodic Dysphonia
    U.S. DEPARTMENT OF HEALTH AND HUMAN SERVICES ∙ National Institutes of Health NIDCD Fact Sheet | Voice, Speech, and Language Spasmodic Dysphonia What is spasmodic dysphonia? Parts of the throat involved Spasmodic dysphonia, or laryngeal dystonia, is a disorder in spasmodic dysphonia affecting the voice muscles in the larynx, also called the voice box. When you speak, air from your lungs is pushed between two elastic structures—called vocal folds—causing them to vibrate and produce your voice. In spasmodic dysphonia, the muscles inside the vocal folds spasm (make sudden, involuntary movements), interfering with vocal fold vibrations. Spasmodic dysphonia may occur along with other forms of dystonia that cause repeated spasms in other parts of the body, including the eyes, face, jaw, lips, tongue, neck, arms, or legs. Spasmodic dysphonia causes voice breaks during speaking and can make the voice sound tight, strained, or breathy. In some people, the breaks occur once every few sentences. In more severe cases, spasms may occur on every word, making a person’s speech very diffcult to understand. Some people with spasmodic dysphonia may also have vocal tremor—a shaking of the larynx and vocal folds that causes the voice to tremble. Source: NIH/NIDCD Spasmodic dysphonia is a chronic condition that continues throughout a person’s life. Spasmodic dysphonia may develop suddenly, with severe voice symptoms present from What are the types of spasmodic the start of the disorder, or it may start with mild symptoms dysphonia? and occur only occasionally before worsening and becoming } Adductor spasmodic dysphonia is the most more frequent over time.
