“…In adductor spasmodic dysphonic microlaryngeal RF ablation was carried out by Remacle et al in unilateral recurrent nerve [10] and by Kim et al on bilateral thyroarytenoid muscles [11]. Timms et al performed it in laryngeal [12] while Carney et al in tracheolaryngeal papillomatosis; the latter authors found it as a direct alternative to CO 2 laser [13].…”

Besides cold-steel and laser instruments, the use of radiofrequency (RF) devices in transoral microsurgery is getting increasing popularity mainly due to its minimal thermal effect on the collateral soft tissue. Authors summarize their surgical technique, results, and experience gained with RF applied during laryngeal interventions at the Department of Otorhinolaryngology, Head and Neck Surgery at Medical School, University of Pécs. Transoral microsurgery using radiofrequency was carried out in 23 cases in total between 1 January 2011 and 1 March 2013. Fourteen histopathologically different benign lesions and 9 malignant planocellular carcinomas of the larynx were removed using different Micro-Larynx RF Probes powered by Surgitron Dual 4.0 MHz Frequency RF (Ellman International, Oceanside, NY, USA) device. No major bleeding event occurred during or after the procedures and neither laryngeal oedema nor significant postoperative pain was recorded. Authors also reviewed the international literature in this topic while detailing some of their most interesting cases.

“…In 2008, TA myectomy was performed using a radiofrequency device. Although the results were initially good, complaints recurred in half of the patients who were then injected with botulinum toxin (30). In Japan, laryngologists have focused on surgical treatment, particularly because botulinum toxin is not state approved in the treatment of SD.…”

Spasmodic dysphonia (SD) is focal dystonia involving intrinsic laryngeal muscles. It occurs because of a disorder in laryngeal motor neuron control during speech. Voluntary speech is affected, while involuntary actions such as loughing, crying, or coughing are not affected. An irregularity in organization in the central nervous system is observed in the pathophysiology of the disease. Some genetic mutations are found be responsible, and the disease is inherited in an autosomal dominant manner. There are two types of the dissease: adductor and abductor. The adductor type is more frequent. The diagnosis is usually delayed because of lack of exact objective criteria. Laryngeal electromyography (EMG) is the test that provides the most valuable diagnostic results. Injecting botulinium toxin into the densest muscle is the treatment of choice.

“…In 2008, a similar technique was used to produce a bilateral myectomy of the thyroarytenoid muscle in 20 cases who has all previously responded to thyroarytenoid botulinum toxin injections [43 • ]. The prepost and follow-up examinations were performed by members of the research team in an unblinded fashion, which may have biased the results.…”

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.
