Thirteen patients (62%) had a minor component of spasmodic dysphonia in addition to their tremor. Fourteen patients had vertical and horizontal components to their tremor, and two had horizontal tremor alone. The remaining five patients did not have clear characterization of their tremor. A total of 49 injections were reviewed (25 thyroarytenoid [TA], 24 thyroarytenoid and strap muscle [TA+S]), and patients reported subjective voice benefit with 48 (96%) of these (92% TA, 100% TA+S). When available, the postprocedural change from baseline Voice Handicap Index\u201010 and Consensus Auditory Perceptual Evaluation of Voice scores were calculated (mean overall: \u22121.9, \u22127.8; TA: \u22122.7, \u22123.5; TA+S: \u22121.4, \u221210.3, respectively). Subjective patient improvement ratings (scale 0%\u2013100%) were obtained for 46 injections, with a mean of 70% improvement per injection. Of patients with both horizontal and vertical tremor, outcomes were improved with TA+S injection versus TA alone (mean improvement 74% vs. 35%, P<\/jats:italic>\u2009<\u2009.005).<\/jats:p><\/jats:sec>Conclusions<\/jats:title>There is utility in the characterization of vertical and horizontal components of vocal tremor.
