Voice Quality after Recurrent Laryngeal Nerve Resection and Immediate Reconstruction

Objective To evaluate clinician perception of voice quality, patient self-reported psychosocial impact of dysphonia, and glottic closure in patients who have undergone resection of the recurrent laryngeal nerve (RLN) and immediate operative reconstruction during thyroid surgery. Study Design Prospective observational study. Setting Single tertiary care hospital. Subjects and Methods Nine patients underwent immediate operative reconstruction of the RLN by the senior author from 2002 to present. Outcome measures included (1) perceptual voice ratings assessed using the GRBAS (Grade, Roughness, Breathiness, Asthenia, Strain) scale, (2) psychosocial impact of dysphonia assessed using the Voice Handicap Index (VHI), and (3) assessment of glottic closure from laryngeal videostroboscopy. Results The RLN was reconstructed with primary anastomosis (4), free nerve graft (3), or vagus-RLN anastomosis (2). Seven patients had voice samples and videostroboscopy examinations obtained at a minimum of 9 months from surgery. Six were judged to have slight disturbance of voice based on overall Grade scoring (G = 1). Five rated their voice as normal or mild on the VHI instrument (score range 8-29). Laryngeal analysis revealed the immobile vocal fold in the median, physiologic phonating position with preserved bulk, recovered tension, and glottic closure during phonation. Three patients less than 9 months from surgery had an expected severe self-reported rating of dysphonia. Conclusion Primary anastomosis, free nerve grafting, and vagus-RLN anastomosis are viable options for RLN reconstruction. Patients who undergo resection and immediate reconstruction of the RLN are able to regain self-perceived functional voices.
