Introduction. In our department the standard surgical procedure for multinodular\r\ngoiter used to be subtotal resection. Over the years, total thyroidectomy has progressively\r\nreplaced subtotal resections and is performed in most of our patients at present.\r\nPatients and Methods. In a prospective cohort, observational study, we assessed\r\nthe immediate surgical outcome in 742 consecutive patients with multinodular goiter\r\n(MNG), admitted for surgery and operated in our hospital. Of all patients, 664 were women\r\n(89.5%) and 78 men (11.5%), aged 15 to 85 years, mean (?SD) of 48 ?13.8 years. Pathology\r\nwas done on frozen and permanent sections. The complications directly related to surgery\r\nin subtotal thyroidectomy (STT) were compared to total thyroidectomy (TT) or near-total\r\nthyroidectomy (NTT) patients: temporary hypoparathyroidism, temporary RLN injury,\r\npermanent hypoparathyroidism and permanent RLN injury. The &#967;2 test (95% confidence\r\ninterval) was used and values of p<0.05 were considered significant.\r\nResults. There were no significant differences among the patients with SST for\r\nMNG, NTT or TT , and TT for recurrent MNG or completion thyroidectomy, with respect\r\nto temporary and permanent RLN injury. Significant differences were found for temporary\r\nhypoparathyroidism in STT for MNG (9 out of 361 patients, 2.45%) and NTT or TT for\r\nMNG (21 out of 266 cases, 7.89%) (p<0.01) and between STT for MNG (9 out of 361 cases,\r\n2.45%) and TT for recurrent MNG for completion thyroidectomy (8 out of 45 cases,\r\n17.77%) (p<0.01) and no difference between NTT or TT for MNG (21 out of 266 cases,\r\n7.89%) and TT for recurrent MNG or completion thyroidectomy (8 out of 45 cases, 17.77%)\r\n(p=0.11). We registered no permanent hypoparathyroidism in our patients.\r\nConclusions. Total thyroidectomy is now the preferred option for the management\r\nof patients with bilateral benign MNG. However, TT is associated with a considerable rate\r\nof complications, higher than of STT. In patients with bilateral MNG and no malignancy,\r\nSTT remains in our opinion, a valuable option.
