Objective:To investigate the value of retrograde thyroidectomy from top to bottom in the operation of retrosternal thyroid surgery. Methods:Retrospective analysis was performed on the cases of retrosternal goiter excised by our surgeons from January 2017 to June 2022,the technical points, feasibility and advantages of the operation were summarized. Results:A total of 15 cases of retrosternal goiter treated by retrograde thyroidectomy were collected, including 5 cases of type Ⅰ retrosternal goiter and 10 cases of type Ⅱ retrosternal goiter.The postoperative pathology was benign. The surgical time is 40-60 minutes for unilateral retrosternal goiter and 70-90 minutes for bilateral goiter. All patients were discharged normally within 7 days after operation, and no operative complications were observed such as bleeding, hoarseness or hypoparathyroidism. Conclusion:This surgical excision method of thyroid is suitable for the type Ⅰ and type Ⅱ retrosternal goiter surgery, which can avoid the difficulties in exposing and separating the the inferior thyroid behind the sternum in conventional surgical method, speed up the operation and reduced the difficulty of operation, and has certain promotion value in clinic.

To investigate the risk factors for hypoparathyroidism after thyroidectomy.
 Methods: Clinical data of 492 patients, who underwent thyroidectomy from April 2015 to December 2016 from Xiangya Hospital of Central South University, were studied retrospectively. Chi-square test and multivariable logistic regression were performed to find the risk factors for postoperative hypoparathyroidism.
 Results: The incidence of postoperative hypoparathyroidism was 43.5%, and the incidence of temporary and permanent hypoparathyroidism was 43.1% and 0.4%, respectively. Univariate analysis showed that tumor pathology, thyroidectomy types, the extent of lymph node dissection, application of carbon nanoparticles, and merged Hashimoto's thyroiditis were risk factors for postoperative hypoparathyroidism (all P<0.01). Logistic regression analysis showed that: thyroidectomy types (OR=0.149, 95% CI 0.078 to 0.28), the extent lymph node dissection (OR=0.779, 95% CI 0.617 to 0.983) and application of carbon nanoparticles (OR=1.729, 
95% CI 1.067 to 2.801) were independent risk factors for postoperative hypoparathyroidism (all P<0.05).
 Conclusion: Hypoparathyroidism is a common complication after thyroidectomy. The incidence of postoperative hypoparathyroidism is significantly increased in patients underwent total thyroidectomy and cervical lymph node dissection. Application of carbon nanoparticles intraoperatively can reduce the incidence of postoperative hypoparathyroidism.

OBJECTIVE: To systematically evaluate the efficiency and safety of total thyroidetomy (including near-total tyhroidectomy) versus subtotal thyroidectomy for multinodular goiter. METHODS: The literatures were searched from Cochrane Library, PubMed, Embase, Chinese Biological Medical Datebase, Chinese National Knowledge Infrastructure, and Chinese Science and Technology Journal Full-text Database as of November 2013. We included all randomizad controlled trials on total (including near-total) versus subtotal thyroidectomy in the treatment of multinodular goiter. The collecting of data and quality assessment were respectively completed by 2 researchers. RevMan5.1 software was used for Meta-analysis. RESULTS: We collected 7 literatures conforming to the standard, incuding 2 192 patients. The Metaanalysis outcomes showed that total thyroidectomy was associated with lower nodule recurrence rate (OR=0.13, 95% CI: 0.07-0.22, P<0.001) and higher in transient hypoparathyroidism rate (OR=2.33, 95% CI: 1.72-3.17, P<0.001). However, no statistical difference was seen comparing total and subtotal thyroidectomy in permanent recurrent laryngeal nerve paralysis rate (OR= 0.81, 95% CI: 0.24-2.74, P=0.74) and permanent hypoparathyroidism rate (OR=2.94, 95% CI: 0.48- 18.11, P=0.24). CONCLUSION Nodule recurrence rate of total thyroidectomy for multinodular goiter is lower than subtotal thyroidectomy and does not increase permanent complications.

Objective:To investigate the relationship between parathyroid hormone（PTH） level and permanent hypoparathyroidism（PHPP） on the first day after radical papillary thyroidectomy, and its predictive value. Methods:A total of 80 patients with papillary thyroid cancer who underwent total thyroid resection and central lymph node dissection were collected and analyzed from January 2021 to January 2022. According to whether PHPP occurred after surgery, the patients were divided into hypoparathyroidism group and normal parathyroid function group, and univariate and binary logistics regression were used to analyze the correlation between PTH and serum calcium levels and PHPP on the first day after surgery in two groups. The dynamic changes of PTH at different time points after operation were analyzed. The area under the receiver operating characteristic was used to evaluate the predictive power of PTH on the development of PHPP after surgery. Results:Among the 80 patients with papillary thyroid cancer, 10 cases developed PHPP, with an incidence rate of 12.5%. Binary logistics regression analysis showed that PTH on the first postoperative day（OR=14.534, 95%CI: 2.377-88.858, P=0.004） was an independent predictive risk factor for postoperative PHPP. Taking PTH=8.75 ng/L on the first postoperative day as the cut-off value, the AUC of the area under the curve was 0.874（95%CI: 0.790-0.958, P<0.001）, the sensitivity was 71.4%, the specificity was 100%, and the Yoden index was 0.714. Conclusion:PTH level on the first day after total thyroid papillary carcinoma surgery is closely related to PHPP, and is an independent predictor of PHPP.

OBJECTIVEIn order to explore the management of peri-operation and the therapeutic effect in the surgical treatment of hyperthyroidism.

METHODSFifty five cases of hyperthyroidism were undergone near-total thyroidectomy, during the operation recurrent laryngeal nerve was exposed, and the parathyroid was found with microscope when necessary. The third rank of inferior thyroid arteries were ligated to guarantee the blood supply for parathyroid.

RESULTSAll cases underwent near-total thyroidectomy. There was no mortality, and no permanent recurrent laryngeal nerve palsy occurred, and no permanent hypoparathyroidism, and no recurrent hyperthyroidism. Follow-up was carried out 16 months to approximately 5 years after near-total thyroidectomy patients, Hypothyroidism occurred in 15 cases (57.7%), serum calcium levels were 2.15-2.45 mmol/L.

CONCLUSIONSSpecial attention should be given to the management of peri-operation, the above the method can prevent operative complication in the surgical treatment of hyperthyroidism, with excellent result.

The aim of this study was to investigate the complications following surgical treatment of thyroid cancer and the association between the extent of surgery and complication rates. A total of 2,636 patients who underwent surgery due to thyroid cancer were retrospectively reviewed to identify surgical complications. Complication rates were assessed according to the extent of surgery, which was classified as follows; less-than-total thyroidectomy with central compartment node dissection (CCND) (Group I, n=636), total thyroidectomy with CCND (Group II, n=1,390), total thyroidectomy plus ipsilateral neck dissection (Group III, n=513), and total thyroidectomy plus bilateral neck dissection (Group IV, n=97). The most common surgical complication was symptomatic hypoparathyroidism, of which 28.4% of cases were transient and 0.3% permanent. The other surgical complications included vocal cord palsy (0.7% transient, and 0.2% permanent), hematoma (0.5%), seroma (4.7%), chyle fistula (1.8%), and Horner's syndrome (0.2%). The complication rates increased significantly with increasing the extent of surgery from Group I to Group IV. The more extensive surgery makes more complications, such as hypoparathyroidism, seroma, and others.

OBJECTIVE: To explore the changes of parathyroid hormone (PTH) and serum calcium alter total thyroidectomy and summarize the methods to prevent and treat the hypoparathyroidism and hypocalcernia. METHOD: Seventy-three patients with total thyroidectomy in our hospital were divided into three groups according to the scope of the operation. The serum concentrations of PTH and calcium were measured and compared before surgery and after surgery 1 h, 1 d, 3 d and 5 d. RESULT: In three groups, the serum concentrations of PTH and calcium were significantly decreased (P<0. 05) after surgery and low serum PTH and hypocalcemia occured. The severity of low serum PTH and hypocalcemia was as follows: total thyroidectomy with bilateral compartment lymph node dissection (CLND)>total thyroidectomy with unilateral CLND>total thyroidectomy. The differences were statistically significant. The levels of PTH after surgery 1 hour and 1 day were effective to predict hypocalcemia. CONCLUSION Total thyroidectomy can affect the parathyroid function. The greater the scope of surgery, the higher the possibility of postoperative hypoparathyroidism. The reasonable operative procedures and more protection of parathyroid during operation can reduce the incidence of hypoparathyroidism. The level of postoperative PTH can be used as a predictive index of hypocalcemia.

PURPOSE: Pseudohypoparathyroidism is a hereditary disorder characterized by symptoms and signs of hypoparathyroidism, typically in association with distinctive skeletal and developmental defects. Hypoparathyroidism is caused by a insufficient end-organ response to PTH (parathyroid hormone). Hypoparathyroidism consists of four types in which the most common form, pseudohypoparathyroidism-Ia, accompany with Albright's hereditary osteodystrophy. We experienced a case of a woman who had been suffering from calcified mass on left foot, diagnosed Albright's hereditary osteodystrophy. METHODS: We present a case of a 24-year-old Korean female who visited plastic surgery department with a painful mass on dorsum of the left foot. On the physical exam, bony hard and painful mass, fixed to dermis, was noted. Plain X-ray films demonstrate suspicious calcification on subcutaneous tissue of dorsum of the left foot. The patient was diagnosed pseudohypoparathyroidism 2 years ago at the plastic surgery department. At the visiting time, the laboratory results were within normal range even though the patient actually had a disease. The reason is because the patient has been treated with Vit.D, calcium replacement therapy and thyroid hormone therapy. Moreover, the patient has been treated with anticonvulsant agents due to epilepsy. On the brain computer tomography (CT), calcification was noted on the basal ganglia and dentate nucleus. So we decided the total excision of entire mass from the left foot. RESULTS: We excised main mass with numerous pinhead sized masses which were scattered around the main mass. The 6.0x4.0x0.5 cm sized main mass was bony hard, and its surface was flat and margin was irregular. The permanent biopsy was confirmed that the main mass and all the scattered tiny masses were heterotopic calcification. The patient did not suffer from the pain after the mass excision. The wound has been healed without any problem. CONCLUSIONS: Heterotrophic calcification is often accompanied with pseudohypoparathyroidism, but such a huge one is uncommon. We report a case of pseudohypoparathyroidism with heterotrophic calcification developed in dorsum of left foot who was diagnosed by excisional biopsy.
