Objective To investigate the factors associated with long-term efficacy of microvascular decompression for hemifacial spasm. Methods 253 cases of hemifacial spasm treated with microvascular decompression were followed 13 to 144 months (mean 73 months). Results Hemifacial spasms were obliterated in 232 cases (91.7%) and were partially relieved in 10 cases (4%). However, hemifacial spasm recurred 11 cases (4.3%). We re-operated on those who had recurrent hemifacial spasm and found that the material used for previous decompression had moved. The movement of decompression material could be the cause of spasm recurrence. Conclusions Upholding of depression material around the blood vessels against movement near the facial nerve plays an important role for improving the long-term efficacy of MVD for hemifacial spasm.

TSH suppression therapy plays an important role in differentiated thyroid carcinoma. It can lower mortality and recurrence rate in high risk patients. Meanwhile, it also has potential side effects on cardiovascular and skeletal systems. Thus, TSH suppressive therapy should be individualized in regard to its possible benefit and potential adverse effects.

Objective To investigate the cause of reoperation for high differentiated thyroid carcinoma and the risk factors of neck lymph node metastasis in reoperation. Methods Retrospectively reviewed the clinical data of 54 high differentiated thyroid cancer patients from 1998 to 2005, who received reoperation and neck lymph node dissection simultaneously. Results The residual thyroid carcinoma rate and lymph node metastasis rate were higher in 39 patients who initially received partial thyroidectomy than in 15 who previousely underwent radical operation(P <0. 05). Age less than 45 years, lymphadenectasis before initial operation, tumor residued or relapsed, muhicentricity of primary cancer and blurred boundary between cortex and medulla of lymph node were the risk factors for ipsilateral lymph node metastasis(P <0. 05), while mul-ticentricity of primary cancer and contralateral thyroid cancer were the risk factors for contralateral lymph me-tastasis (P < 0. 05). Conclusions Individual standard radical operation and necessary lymph node dissection are important measures to prevent recurrence and reoperation. Completion thyroidectomy and modified or selec-tive neck dissection are recommended for reoperation patients with the risk factors of lymph node metastasis.

Postoperative hypothyroidism is the most common complication following thyroidectomy,and thyroxine replacement is needed to maintain thyroid function.Levothyroxine (L-T4) is the preferred drug for the treatment of hypothyroidism.L-T4 therapy can be initiated immediately after thyroid operation,and the dosages are influenced by target serum TSH and several other factors.Special consideration should be taken for such patients,including patients with poor compliance,during pregnancy,and elderly patients.Thyroid function should be measured every 4 to 6 weeks,optimal dosages are adjusted according to target serum TSH individually,avoiding under-treatment or over-treatment.T3 in divided doses or L-T4/T3 combination therapy can be served as alternative for those failed to L-T4 therapy alone.
