“…1,2,6,7 Commonly observed speech patterns in those with hyperkinetic dysarthria include unexpected variations in pitch or loudness, inappropriate pauses, constant or intermittent dysphonia, constant or intermittent hyper-or hyponasality, articulatory imprecision, and slow speaking rate due to frequent or extended pause durations. 1,2,7,8,20,[49][50][51][52][53][54][55][56][57][58][59][60][61][62][63] The sustained voicing task elucidates minor variations in vocal tract configuration in those with hyperkinetic dysarthria. For example, vocal unsteadiness and tremor can be perceived, as can subtle unintended articulatory movements associated with production of the vowel, ''ah''.…”

Background: Hyperkinetic dysarthria is characterized by abnormal involuntary movements affecting respiratory, phonatory, and articulatory structures impacting speech and deglutition. Speech-language pathologists (SLPs) play an important role in the evaluation and management of dysarthria and dysphagia. This review describes the standard clinical evaluation and treatment approaches by SLPs for addressing impaired speech and deglutition in specific hyperkinetic dysarthria populations. Methods: A literature review was conducted using the data sources of PubMed, Cochrane Library, and Google Scholar. Search terms included 1) hyperkinetic

“…8,9 More recent studies have shown improvements in acoustic, aerodynamic, and perceptual characteristics of the voice. 10 A recent study by Rojas et al 11 showed an improvement in oscillation intensity, voice breaks, and vocal tremor following BoNT injection, as well as improved self-perception of voice using the Voice Handicap Index (VHI). Those benefits were present at 30 days but not after 120 days following reinnervation.…”

Objective The purpose of this review is to describe the recent advances in characterizing spasmodic dysphonia. Spasmodic dysphonia is a task-specific focal laryngeal dystonia characterized by irregular and uncontrolled voice breaks. The pathophysiology is poorly understood, and there are diagnostic difficulties. Data Sources PubMed, Google Scholar, and Cochrane Library. Review Methods The data sources were searched using the following search terms: ( spasmodic dysphonia or laryngeal dystonia) and ( etiology, aetiology, diagnosis, pathogenesis, or pathophysiology). Conclusion The diagnosis of spasmodic dysphonia can be difficult due to the lack of a scientific consensus on diagnostic criteria and the fact that other voice disorders may present similarly. Confusion can arise between spasmodic dysphonia and muscle tension dysphonia. Spasmodic dysphonia symptoms are tied to particular speech sounds, whereas muscle tension dysphonia is not. With the advent of more widespread use of high-speed laryngoscopy and videokymography, measures of the disruptions in phonation and delays in the onset of vocal fold vibration after vocal fold closure can be quantified. Recent technological developments have expanded our understanding of the pathophysiology of spasmodic dysphonia. Implications for Practice A 3-tiered approach, involving a questionnaire, followed by speech assessment and nasolaryngoscopy is the most widely accepted method for making the diagnosis in most cases. More experimental and invasive techniques such as electromyography and neuroimaging have been explored to further characterize spasmodic dysphonia and aid in diagnosing difficult cases.

“…Adductor spasmodic dysphonia (ADSD) is a form of dystonia that affects the vocal cords, resulting in a strangled, interrupted voice quality. A poorly understood disorder affecting only ~1 in 100,000 individuals, 1 ADSD nonetheless causes considerable distress: the increased effort required to speak combined with reduced comprehensibility of speech leads to compromised communication, which is associated with decreased quality of life in functional, emotional, and social domains 2 . The use of continuous botulinum toxin (BTX) injections has been the standard treatment worldwide because Blitzer reported its effectiveness for ADSD in the 1990s 3 .…”

ObjectiveTo determine the durability of current titanium implants (TI) used in voice improvement surgery for adductor spasmodic dysphonia (ADSD), which is type II thyroplasty (T2T), and identify the effects of their fractures on vocal functions.MethodsA total of 36 ADSD patients who underwent T2T had the following exams: The CT scans of the larynx were performed 1 year after the surgery to assess the fractures of TI. The improvement in the mean voice handicap index 10 (VHI‐10) scores and the success rate between nonfractured (NFR) and fractured (FR) groups were compared.ResultsIt was indicated that TI was broken in 21 cases (58.3%). In one case (2.7%), a fracture on the part of the bridge that connects both sides of the plates was observed, and fractures at holes placed on the plates in the other 35 cases (55.6%). The mean VHI‐10 score improved from 27.2 ± 8.1 to 11.4 ± 7.9 in the NFR group and from 26.3 ± 4.9 to 9.7 ± 7.9 in the FR group. The success rates were 66.6% in the NFR group and 71.5% in the FR group. No statistical difference was observed in the improvement in the mean VHI‐10 scores, and the success rate between the two groups. However, two cases resulted in failure in the FR group, whereas no worsened case was observed in the NFR group.ConclusionThe current TI used in T2T has low durability and could result in the worsening of vocal symptoms after the surgery.Level of Evidence4 Laryngoscope, 2023
