[Repeat surgery for thyroid nodules (excluding cancer and hyperthyroidism)]. / Reprises chirurgicales en pathologie nodulaire thyroïdienne (cancer et hyperthyroïdie exclus).

Second procedures for recurrent thyroid disease are known to carry a high risk of iatrogenic damage, particularly to the inferior laryngeal nerves and parathyroid glands. This risk has been clearly evaluated for the primary procedure, but is less clearly for second procedures. A series of 117 patients with solitary or multiple cold thyroid nodules were evaluated (excluding those patients re-operated for recurrent thyroid carcinoma or goitre associated with hyperthyroidism) to determine the operative risks. The level of transient and permanent recurrent laryngeal nerve palsy was 2.56% and 1.7% respectively. The level of transient and permanent hypocalcaemia was 12.9% and 4.62% respectively. The frequency of re-operation for recurrent disease involving the pyramidal lobe following total thyroidectomy (6 cases) highlights the importance of removing it during the primary procedure. The number of cases of cancer discovered at re-operation was 4.3% (5 cases out of 117).
