Objective: To identify incidental parathyroidectomy predictors in thyroid surgery.
Methods: All thyroid operations during 4 years were reviewed (n=1010). Patients were divided in those with (parathyroidectomy group) and without incidental parathyroidectomy (no-parathyroidectomy group).
Results: Incidental parathyroidectomy occurred in 198 patients (19.6%). The groups were comparable in age, thyroid weight and pathology, hyperthyroidism, operative time, surgeon’s experience (high/low volume), operative technique (suture-ligation/Ligasure/Ultracision), surgical procedure (total, near-total, subtotal, hemi-thyroidectomy), modified radical or central neck dissection, reoperation, postoperative calcium, transient and permanent hypocalcemia. Women composed 87.9% of the parathyroidectomy and 70.3% of the no-parathyroidectomy group (P=0.0001), and 83.2% of patients with intrathyroidal but 73% of non-intrathyroidal parathyroid glands (P=0.001). Female gender was the only predictor in multivariate analysis (P=0.0001,OR=3.28,95%CI=2.04–5.27).
Conclusions: In contrast to all other analyzed parameters, female gender was an independent risk factor of incidental parathyroidectomy in all types of thyroid surgery, probably due to higher likelihood of intrathyroidal parathyroid glands.
