## Clinical Context Recurrent laryngeal nerve injury is a known complication of thyroid surgery, occurring in 0.5–2% of cases even with careful dissection. The paramedian position of the vocal cord indicates RLN paralysis. ## Rationale for Observation **Key Point:** The standard of care for acute RLN injury post-thyroidectomy is conservative management with observation for 3 months, as spontaneous recovery occurs in up to 50% of cases due to nerve regeneration or collateral innervation. **High-Yield:** The critical distinction is between: - **Acute RLN injury (post-operative):** Observe 3 months → then consider intervention if no recovery - **Intraoperative RLN transection (recognized immediately):** Immediate repair/anastomosis In this case, the nerve was identified and preserved intraoperatively; the paralysis is likely from traction, stretching, or thermal injury—not transection. These injuries have excellent spontaneous recovery rates. ## Supportive Measures During Observation - Voice rest and speech therapy to optimize vocal cord function - Reassurance and counseling regarding prognosis - Serial laryngoscopy at 6–8 weeks and 3 months to document recovery ## When to Escalate If no recovery by 3–6 months: - Electromyography to assess degree of denervation - Injection laryngoplasty or medialization procedures - Consideration of reinnervation surgery (ansa cervicalis–RLN anastomosis) **Clinical Pearl:** Immediate re-exploration or injection in the acute phase is not indicated unless there is evidence of complete transection or failure to identify the nerve intraoperatively.
