A long term observation from our operated patients revealed that recurrence of lymph node metastasis was seen in 9.4% of 170 patients with differentiated carcinoma after modified neck dissection. The highest incidence of the recurrence, 15.4%, was observed in 65 patients operated only by local excision of involved lymph nodes. Recurrence of regional lymph node metastasis occured in 5.2% of 194 patients after resection of only the primary tumor.
These results suggest that modified neck dissection is apparently the first choice of treatment for lymph node metastasis of differentiated carcinoma of the thyroid. Local excision, however, is not adequate procedure for the patients with lymph node metastasis. The prophylactic lymph node dissection is less importance in cases with no gross nodal involvement at time of surgery.
Details of operative technique of modified neck dissection were presented by cinefilm in which the sternocleidomastoid muscle, spinal accessory nerve, vagus nerve, recurrent laryngeal nerve, carotid arteries were preserved. This procedure has an advantage of reducing cosmetic deformity and preserving function.
