Hoarseness After Total Thyroidectomy: Early Thyroplasty Versus Observation
38-year-old woman undergoes total thyroidectomy for a 1.8 cm papillary thyroid carcinoma. No neck dissection is performed. On postoperative day 1 she reports a breathy voice and cannot project in her job as a schoolteacher. Flexible laryngoscopy shows the right vocal fold immobile in a paramedian position and the left vocal fold mobile; there is a visible glottic gap on phonation. She has no stridor, dyspnea, or aspiration, and oxygen saturation is 98% on room air. The surgeon recommends immediate type I thyroplasty 'before the nerve dies.' She is otherwise healthy, has no neck hematoma, and wants to know whether waiting will reduce her chance of recovery. She asks about returning to teaching within 2 weeks. Calcium is 9.1 mg/dL, and the drain has serosanguinous output. She has no prior voice disorder.
1. What is your immediate airway and voice assessment, and would you reexplore the neck now?
Read the worked answer
First I would assess airway and swallowing with flexible laryngoscopy, which is already done: unilateral immobility, no stridor, oxygen saturation 98%, and no aspiration. That means no immediate surgical airway. I would not reexplore the neck solely for hoarseness on day 1; reexploration is urgent for expanding hematoma, suspected ligature around the nerve, or bilateral vocal fold immobility with airway compromise. I would document the findings, start voice rest and speech-language pathology, and explain that many unilateral palsies recover over 6–12 months. I would also check calcium and drain output. Immediate thyroplasty 'before the nerve dies' is not evidence-based; the nerve is not saved by medialization, and early surgery can complicate assessment of spontaneous recovery.
2. How do you use laryngeal EMG and the timing of injection laryngoplasty?
Read the worked answer
Laryngeal EMG at 3–6 weeks helps distinguish neurapraxia from axon loss and can inform prognosis, but it does not change the need for voice therapy. If she has severe dysphonia, a large glottic gap, or aspiration, early injection laryngoplasty with a temporary filler such as hyaluronic acid can improve voice and cough while waiting for recovery. I would not do permanent thyroplasty at 1 week. If EMG shows severe denervation and no recovery by 6–12 months, type I thyroplasty or arytenoid adduction is appropriate. She should be reassessed monthly; if she develops aspiration or stridor, the plan changes immediately.
3. How would you counsel her about recovery, returning to teaching, and permanent options?
Read the worked answer
I would tell her that spontaneous recovery is possible for up to 12 months and that waiting does not 'kill' the nerve; the injury has already occurred. Voice therapy can reduce compensatory strain. For a teacher, early temporary injection may allow return to work sooner, but it is a shared decision. Permanent medialization is considered after 6–12 months of observation if the voice remains poor. I would also discuss the small risk of aspiration and the need to monitor the airway if the contralateral fold later becomes immobile. Returning to teaching within 2 weeks may be possible with amplification and voice therapy, but not if she has a wide glottic gap and fatigue.
