Among the topics are speech-language pathology and the professional voice user: an overview, amateur and professional child singers: pedagogy and related issues, psychiatric manifestation of medications prescribed commonly in otolaryngology,
cricoarytenoid and cricothyroid joint injury: evaluation and treatment, and nursing considerations in the care of the professional voice.
If the patient is not treated early laryngeal TB can result in subglottic stenosis, muscular involvement and vocal cord paralysis when the
cricoarytenoid joint or recurrent laryngeal nerves are invaded.
Such findings are consistent with a research which showed that training through phonation into a tube promotes activation of the thyroarytenoid, cricothyroid and lateral
cricoarytenoid muscles 14.
Persistent vocal fold limitation in the median position with
cricoarytenoid joint fixation was still noted after 1 month; however, the patient complained of neither hoarseness nor choking.
Cricoarytenoid subluxation or dislocation is more likely to occur during internal trauma such as intubation injury rather than blunt external laryngeal trauma.
2]O), spasmodic activity of the diaphragm, no contraction of the abdominal muscles, and phasic inhibition of the abductor laryngeal muscle (posterior
cricoarytenoid muscle) [7].
There even exists a "NG tube syndrome" (5), the pathophysiological mechanism of which is thought to be paresis of the posterior
cricoarytenoid muscles secondary to ulceration and infection over the posterior lamina of the cricoid.
Additionally, the epiglottis-posterior hypopharyngeal wall distance was narrowed, and the inferior constructor muscle and posterior
cricoarytenoid muscle were compressed due to osteophytes on the left side.
Result: Inappropriate size or location of the implant material were defined in two subjects, inappropriate management of the inner perichondrium of thyroid lamina (IPTL) were defined in 5, and
cricoarytenoid joint (CAJ) fixation in one.
Bilateral transarytenoid and lateral
cricoarytenoid myectomy--This surgery is usually performed one side at a time, at least six months apart.
In such condition the treatment options available are trans-oral carbon dioxide (CO ) laser 2 endoscopic arytenoidectomy, endoscopic laser cordotomy, extra laryngeal arytenoidectomy, arytenoids lateralization and posterior
cricoarytenoid muscle reinnervation.
Assessment of posterior
cricoarytenoid botulinum toxin injections in patients with abductor spasmodic dysphonia.
