“…One report suggested that the use of EMG improves the accuracy of botulinum toxin injections, that the fidelity of the EMG signal may predict injection benefit [57 • ], and that lower doses were more beneficial because of fewer side effects [57 • ]. A report of a portable EMG device allowing the physician to hear the auditory signal during needle placement was introduced to avoid the expense of commercial EMG machines unnecessary for injecting botulinum toxin into the laryngeal muscles [58 • ]. …”

Purpose of review Although botulinum toxin injection is the gold standard for treatment of spasmodic dysphonia, surgical approaches aimed at providing long-term symptom control have been advancing over recent years. Recent findings When surgical approaches provide greater long-term benefits to symptom control, they also increase the initial period of side effects of breathiness and swallowing difficulties. However, recent analyses of quality-of-life questionnaires in patients undergoing regular injections of botulinum toxin demonstrate that a large proportion of patients have limited relief for relatively short periods due to early breathiness and loss-of-benefit before reinjection. Summary Most medical and surgical approaches to the treatment of spasmodic dysphonia have been aimed at denervation of the laryngeal muscles to block symptom expression in the voice, and have both adverse effects as well as treatment benefits. Research is needed to identify the central neuropathophysiology responsible for the laryngeal muscle spasms in order target treatment towards the central neurological abnormality responsible for producing symptoms.

“…Sie können jedoch auch mit Hilfe einer transnasalen flexiblen Endoskopie kontrolliert werden oder bei direkten Mikrolaryngoskopien in Narkose erfolgen [113][114][115]. Für transkutane Injektionen wird zur sicheren Identifizierung des Zielmuskels eine elektromyographische (EMG) Kontrolle empfohlen [116][117][118][119][120]. Doch auch endoskopische Kontrollen sind bei transkutanem Vorgehen möglich und selbst ohne optische oder EMG Kontrollen werden bei der sogenannten "point-touch technique" mit rein taktiler Kontrolle gute Therapieergebnisse nach transkutanen Botulinumtoxin-Injektionen beschrieben [65,[121][122][123].…”

The treatment of laryngeal dystonias with botulinum toxin is successful. Every patient suffering from a laryngeal dystonia should be assured of high quality therapeutic intervention. Therefore it is important to establish general standards by experts in this field. In this connection, we want to focus here on different relevant aspects of laryngeal dystonias. This includes new aspects in etiology, anatomical landmarks for the injection, standards in diagnostics and therapy and finally open issues needing discussion.
