    Summary
    This summary is machine-generated.

    Strumectomy can cause recurrent laryngeal nerve palsies. One year after surgery, many patients with unilateral palsies recover vocal cord function, but some experience persistent paralysis.

    Area of Science:

    • Otolaryngology
    • Neurology

    Background:

    • Strumectomy, a surgical procedure to remove all or part of the thyroid gland, is associated with potential complications.
    • Recurrent laryngeal nerve (RLN) injury can lead to vocal cord paralysis, affecting voice and airway function.

    Purpose of the Study:

    • To evaluate the incidence and outcomes of recurrent laryngeal nerve palsies following strumectomy.
    • To assess the rate of vocal cord function recovery after unilateral and bilateral RLN palsies.

    Main Methods:

    • Retrospective analysis of 1,713 patients who underwent strumectomy over seven years.
    • Follow-up examinations one year post-surgery for patients with documented vocal cord palsies.

    Main Results:

    • 147 patients (8.6%) developed unilateral RLN palsies; 53 were available for follow-up. Of these, 28 had persistent paresis, while 23 showed complete recovery.

  • 22 patients had bilateral RLN palsies; 10 were available for follow-up. Only one patient regained normal function of both vocal cords; others had partial recovery or persistent immobility.

    • Conclusions:

    • Strumectomy carries a significant risk of RLN injury, with varying degrees of functional recovery.
    • Complete recovery of vocal cord function is possible after unilateral RLN palsy, but less likely in cases of bilateral palsy.
