AIMS Thyroid pathology is rare in children and the rate of malignancy is higher than in adults. Thyroid surgery in children is therefore particularly at risk of causing recurrent laryngeal nerve (RLN) palsies. The classical technique for monitoring the RLN is not always adapted to children due to the large size of the dedicated endotracheal tubes. MATERIAL AND METHODS Double-needle electrodes (NIM 3.0) were placed medially or paramedially through the cricothyroid membrane and carefully kept submucosal just below the level of the vocal folds. Before identification of the RLN, the vagal nerve was dissected on the side of the concerned lobe and stimulated. The thyroid surgery was then performed with the routine identification of the RLN. The response of the RLN is periodically checked using a stimulating probe. The main outcomes were the identification and stimulation of the RLN, quality of the voice in post-operative time. OBJECTIVE The main objective of our study is to present a simple and efficient method, available for children of all ages, in order to perform monitoring of the recurrent laryngeal nerves during thyroid surgery. RESULTS We present the results of our retrospective series, in a tertiary-care university pediatric hospital. We included nine children, corresponding to 15 nerves. In all cases, the RLN was identified, stimulated and a positive response was obtained via monitoring. CONCLUSIONS This technique of monitoring is safe, feasible at any age, even in neonates, and, as the electrode stays in the operation field, its position is easily controlled.
