Ansa-RLN reinnervation for unilateral vocal fold paralysis in adolescents and young adults

SummaryObjective/hypothesisTo assess the outcomes of management of unilateral vocal fold paralysis by ansa-RLN reinnervation in a series of patients ages 12–21.Study designClinical outcomes study.MethodsSix consecutive adolescents and young adults (ages 12–21 years) seeking treatment for unilateral vocal fold paralysis and glottal incompetence underwent ansa-RLN neurorraphy. Pre- and post-operative voice recordings acquired at least 1 year following surgery were submitted to acoustic and perceptual analysis. Patient-based measures were also taken.ResultsMean perceptual visual analogue scale rating of dysphonia severity (0 mm = profoundly abnormal voice, 100 mm = completely normal voice) improved from 50 mm pre-operatively to 82 mm post-operatively. Mean maximum phonation time improved from 6.5 s to 13.2 s. Pitch and dynamic range were also observed to improve. Global self-ratings of voice function (0–100%) increased from 31.2% to 81.6% of normal.ConclusionsAnsa-RLN reinnervation is an effective treatment option for adolescents and young adults with unilateral vocal fold paralysis. The procedure has the potential to improve vocal function substantially, especially in those with isolated paralysis of the recurrent laryngeal nerve. The procedure alleviates the disadvantages associated with other surgical options for this age group.
