Method: Neck dissection using the unilateral big hockey stick incision was performed on 23 patients with thyroid carcinoma. Results: The big hockey stick incision results in a cosmetic scar which is barely visible and easily covered by hair or clothing, while it provides sufficient exposure of the operation field. A small area of marginal necrosis is occasionally seen at the apex of the skin flap due to preoperative radiotherapy. Conclusion: The unilateral big hockey stick incision has adequate surgical access, good healing of skin flaps, and a good cosmetic result.展开更多

Although the central neck dissection (CND) is recommended in differentiated thyroid carcinoma, the indication for lateral neck dissection (LND) remains controversial. Design: Retrospective study. Methods and Main Outcome Measures: Pathological analysis of systematic ipsilateral central neck dissection (CND) and LND performed with total thyroidectomy in differentiated thyroid carcinoma was retrospectively reviewed according to “side” and to “patient”. Results: A total of 56 sides (46 patients) were suitable for analysis. Analysis by “side” revealed that CND and LND dissection samples were both negative in 15 cases, both positive in 32, CND was positive and LND was negative for 8 cases and CND was negative and LND was positive in 1 case. The combined presence of positive LND and positive CND was therefore observed in 32/40 “sides” and 26/46 “patients”. Analysis by “side” of the impact of the treatment decision to perform ipsilateral LND only in patients with positive CND and vice versa demonstrated a sensitivity, specificity, and accuracy of 97%, 65%, and 84%, respectively. Conclusions: In most cases, the presence of positive LND was associated with positive ipsilateral CND. The very low prevalence of positive LND in patients with negative CND may justify LND as a second step procedure only in patients with positive CND, except in the case of documented lateral neck metastasis.展开更多

Methods: Neck dissection by using the unilateral big hockey stick incision (BHSI) was performed on 93 patients with head and neck carcinoma. Results: The big hockey stick incision has a cosmetic scar and not scar contraction and is barely visible and easily covered in hair and clothing; sufficient exposure of the operation field; a small area of marginal necrosis was occasionally seen at the apex of the skin flap due to having preoperative radiotherapy. Conclusion: The unilateral big hockey stick incision has adequate surgical access, good healing of skin flaps, and a good cosmetic result.展开更多

Therefore, we analyzed whether sentinel lymph nodes (SLN) biopsy of the first draining nodes in the jugulo-carotid chain is an accurate technique to select patients with true-positive but nonpalpable lymph nodes for selective lateral node dissection. Materials and Methods: From January 2009 to December 2009, 12 patients with solitary papillary carcinoma measuring 2 cm by ultrasonography were included in this study. After the thyroid gland was exposed to avoid injuring the lateral thyroid lymphatic connection, approximately 0.2 ml of 5mg/ml indocyanine green was injected into the parenchyma of upper and lower thyroid gland. Some stained lymph nodes in the jugulo-carotid chain could be identified following the stained lymphatic duct and dissected as the SLN. After that, thyroidectomy with modified neck dissection was performed. Results: The mean tumor size was 22.1 ± 4.6 mm. Identification and biopsy of stained SLN in the ipsilateral jugulo-carotid chain was successful in all 12 cases. In 6 cases, histopathological analysis of SLNs revealed metastases of the papillary thyroid carcinoma. Among them, 2 cases had additional metastatic lymph nodes in the ipsilateral compartment. Of the 6 patients who had negative lymph node metastasis (LNM) in SLNs, all patients had negative LNM in the ipsilateral compartment. Conclusions: The method may be helpful in the detection of true-positive but nonpalpable lymph nodes and may support a decision to perform a selective lateral node dissection in patients with papillary thyroid carcinoma.展开更多
