A retrospective study by Wang et al also looked at risk factors, indicating that those for hypoparathyroidism following thyroidectomy include gender, lateral lymph node dissection, type of surgery, length of surgery time, and application of carbon nanoparticles. Similarly, risk factors for post-thyroidectomy hypocalcemia were found to include age, gender, lateral lymph node dissection, type of surgery, preoperative parathyroid hormone level (PTH) level, operative time, and carbon nanoparticle application. The study involved 278 thyroid surgery patients. [13]

A study by Chen et al indicated that compared with unilateral subtotal thyroidectomy, the risk of hypoparathyroidism is 11.86 times greater in bilateral total thyroidectomy and 8.56 times greater in radical thyroidectomy with unilateral neck lymph node dissection. [14]
