Thyroarytenoid Muscle

Intralaryngeal injections of botulinum toxin (Botox), under electromyographic guidance, have emerged as an effective treatment for adductor spasmodic dysphonia. To remain effective, these injections must be repeated every 3 to 9 months as the symptoms recur. One drawback to the current method is the need for electromyographic confirmation of needle placement into the thyroarytenoid muscle. This report describes an anatomic approach to Botox injection that requires only flexible nasopharyngeal endoscopy and careful evaluation of the anatomic landmarks. This technique has been used successfully on 13 patients, and objective pretreatment and posttreatment measures are reported.

PurposeThe purpose of this study was to determine the influence of symptom severity and disclosure of adductor spasmodic dysphonia (ADSD) on the perceptions of human resource personnel members (HRPs) during a simulated phone interview.MethodOne female speaker with ADSD was recorded reading an interview script at two time points: (a) pre-BOTOX injection (severe), and (b) post-BOTOX injection (mild). Thirty-two HRPs evaluated the recording in one of the two conditions via a qualitative structured interview. HRPs gave their recommendations regarding when and how to disclose ADSD.ResultsIn the mild condition, no HRP perceived that the applicant had a voice disorder. Disclosure was not recommended as often, as an impairment was not initially noticed. However, 15/16 HRPs commented on the applicant's voice in the severe condition, with most suspecting she was a smoker or had lung/throat cancer. Disclosure in the severe condition was recommended more often, as it clarified symptoms that were noted at the outset.ConclusionsSymptom severity in ADSD influences employer perceptions during the phone interview process. Incorrect assumptions may be made about applicants with severe symptoms, and apparentness of symptoms influences whether or not disclosure is recommended. Results have implications for counseling individuals with ADSD who are navigating the job interview process.

This study compared speech intelligibility in nondisabled speakers and speakers with adductor spasmodic dysphonia (ADSD) before and after botulinum toxin (Botox) injection. Standard speech samples were obtained from 10 speakers diagnosed with severe ADSD prior to and 1 month following Botox injection, as well as from 10 age- and gender-matched healthy adults. This yielded 3 speaking conditions: pre-Botox injection, post-Botox injection, and normal control. Thirty phrases were extracted from the speech samples and arranged in a counterbalanced listening experiment. Thirty students, reporting little experience with distorted speech, served as listeners. Each listener's response was scored for words correctly identified using a liberal scoring criterion yielding a percentage of words correctly identified for each speaker. The results indicated that the speakers with ADSD were significantly more intelligible in the post-Botox condition than in the pre-Botox condition. The results also indicated that healthy speakers were significantly more intelligible than the speakers in both the preand post-Botox conditions. In general, these results indicated that intelligibility is affected in severe ADSD and that the use of Botox injection in ADSD improves intelligibility scores. However, the results also indicated that the use of Botox injection does not result in speech intelligibility similar to that of normal, non-ADSD speakers.

The larynx is critical to performing complex tasks of airway protection, phonation, respiration, and deglutition. Various focal and systemic neurologic disorders impact the larynx, causing deficits that lead to dysfunction in voice, speech, breathing, and swallowing function. The most common hyperfunctional neurolaryngeal disorders include spasmodic dysphonia (laryngeal dystonia), essential vocal tremor, and muscle tension dysphonia. Some hypofunctional neurolaryngeal disorders include parkinsonian disorders, neuromuscular junction diseases, and myopathies. A multidisciplinary approach involving evaluation by neurologists, voice-trained otolaryngologists and speech-language pathologists is often key to diagnosis and treatment of these challenging and sometimes lifelong disorders. Botulinum toxin injection into the laryngeal musculature is currently the gold-standard treatment for both spasmodic dysphonia and vocal tremor. However, much research is being conducted to advance less invasive and more definitive medical and surgical treatment interventions.

Stimulation Of

The neuroanatomy of the larynx was explored in seven dogs to assess whether there is motor innervation to the thyroarytenoid (TA) muscle from the external division of the superior laryngeal nerve (ExSLN). In 3 animals, such innervation was identified. Electrical stimulation of microelectrodes applied to the ExSLN resulted in contraction of the TA muscle, indicating that this nerve is motor in function. This was confirmed by electromyographic recordings from the TA muscle. Videolaryngostroboscopy revealed improvement in vocal fold vibration following stimulation of the ExSLN compared to without it. Previously, the TA muscle was thought to be innervated solely by the recurrent laryngeal nerve. This additional pathway from the ExSLN to the TA muscle may have important clinical implications in the treatment of neurologic laryngeal disorders such as adductor spasmodic dysphonia.
