Abstract
Objectives: To evaluate whether the timing of early (≤6 months from time of nerve injury) vs. late (>6 months) injection medialization laryngoplasty impacts the need for subsequent open‐neck reconstruction to restore vocal function in patients with unilateral vocal cord paralysis. Study Design: Retrospective chart review. Methods: A total of 112 outpatient or hospitalized adults with dysphonia resulting from postsurgical or idiopathic unilateral vocal cord paralysis were identified who were injected as initial treatment within 1 year of onset of their paralysis. All subjects underwent awake, transoral, paraglottic injection with absorbable hyaluronic‐acid gel. Patients with documented recovery of vocal cord mobility (22), active disease directly affecting the recurrent laryngeal nerve (8), 6 months postparalysis) avoided phonosurgical reconstruction (P = .03, χ2 test). Conclusions: Patients receiving early injection medialization for vocal cord paralysis were less likely to require transcervical reconstruction. We believe that early medialization creates a more favorable vocal cord position for phonation that can be maintained by synkinetic reinnervation, in contrast to the final position of a lateralized vocal cord being determined solely by reinnervation.
