LEMG guidance of botulinum toxin injections into the TA in patients with adductor spasmodic dysphonia has been an established method for many years. To be effective in the much rarer cases of paradoxical motion of the vocal fold (postneuroleptic laryngeal dyskinesia, laryngeal dyspnea), the LEMG guidance of the botulinum toxin injection into the TA, PCA, or CA is essential [17]. Now, it has been shown that LEMG guidance could also be used for vocal fold injection laryngoplasties. In a prospective study of 60 patients observed for at least 6 months, an office-based awake LEMG-guided hyaluronic acid vocal fold injection for unilateral VFP was performed without using any anesthesia [18]. A 26-gauge monopolar injectable needle electrode was used. The procedure led to satisfactory phonatory results, and the majority needed only a single injection during the 6-month follow-up period.
