[Strategy of points, lines and layers in needle assisted laparoscope functional modified neck dissection through...

The incidence of papillary thyroid carcinoma is growing rapidly. Especially in young patients, the patients have high demand for better cosmetic effect and less psychological trauma. The application of laparoscope technique in papillary thyroid carcinoma surgery should meet the needs of patients. The development of needle assisted technique make it easy to access the neck potential fascial spaces, and provide the basic instrument for laparoscope modified neck dissection. The application of needle assisted techniques mainly include suture suspension and V type needle retractor, MiniLap, 3 mm laparoscopic apparatus. Indications of this procedure is very important, and it is necessary to make full use of the "critical points" , "mark lines" and "fascia layers" to precise positioning in the operation. Furthermore, the levels of dissection must be determined based on the pattern of cervical lymph node metastasis in differentiated thyroid carcinoma, that will make the surgical procedures more safety.
