PURPOSE: Total lobectomy is currently recommended also in benign thyroid disease in order to reduce the risk of goitre recurrence, an approach claimed not to increase post-operative morbidity. The aim of the study was to analyse risk factors for recurrent laryngeal nerve (RLN) palsy during neck surgery, with particular interest in complications after total lobectomy and subtotal resection, respectively.
METHODS: All consecutive patients operated for thyroid and parathyroid diseases at one institution between 1984 and 2011 were prospectively recorded, and 1,322 patients were included. Patients with permanent post-operative RLN palsy were re-examined in 2011.
RESULTS: The risk of permanent RLN palsy after parathyroid surgery was 0.3 %. Patients operated for thyroid cancer had a 5.9 % risk of permanent nerve injury, higher than that of patients with benign thyroid disease (1.4 %; P = 0.029). Independent risk factors for RLN paralysis after benign thyroid surgery were intrathoracic goitre (odds ratio (OR), 3.57; 95 % confidence interval, 1.70-7.48), ipsilateral redo-surgery (OR, 3.64; 1.00-13.28) and total lobectomy (OR, 2.41; 1.05-5.55). At long-time follow-up (median, 10 years), 7 of 12 patients with permanent RLN palsy still suffered moderate or severe symptoms.
CONCLUSIONS: RLN paralysis is an infrequent complication after neck surgery, but with major negative impact on patients' well-being when permanent. Hemithyroidectomy/total thyroidectomy is increasingly preferred over subtotal resection in multinodular goitre. This is supported by an increased risk of RLN injury during redo-surgery for recurrency but should be carefully weighed against individual risk factors for nerve palsy, including surgical experience and volume.
