Background and Objective: Due to the high prevalence of thyroidectomy and accidental removal of parathyroid glands as a complication in this operation, results to transient and permanent hypoparathyroidism. Therefore, we decided to investigate the incidence of parathyroidectomy in patients with thyroid or subtotal thyroidectomy.
Subjects and Methods: This is a descriptive and retrospective study. The data of patients who underwent the thyroidectomy were studied by census method. Required variables including age, sex, type of pathology, the removal of the parathyroid, doctor's field of surgery, cancer status, the size of the removed thyroid and the type of surgery done. The data were collected from through hospital records and pathology by the prepared questioner list were collected. Data were entered into SPSS software version 17 and analyzed using statistical tests.
Results: Of 1159 patients, 1002 (86.5%) women and 157 (13.5%) were male. Of the total thyroidectomy, 81 cases (7%) of accidental parathyroidectomy were found. The mean age of patients was 41.01 ± 6.20 y; mean thyroid diameter was 6.20 ± 2.16 cm. The most common type of pathology in the examined patients was multinodular goiter (52.8%). There was a statistically significant difference between the mean surgeon's work experience with the accidental removal of the parathyroid gland (P<0.05).
Conclusion: According to the results, it can be concluded that accidental parathyroidectomy is not very common in patients undergoing thyroidectomy. The factors of malignant status, ward of surgery, surgeon's work experience and pathology of the lesion are effective on its frequency.
