To assess whether lateral neck dissection can control the hypopharyngeal cancer with clinically regional metastasis.


A retrospective review of medical chart from 1975 to 1992 was performed. Ninety-three hypopharyngeal squamous cell carcinoma patients who had performed RND were included. The distribution of metastatic neck lymph node was analyzed.


Submandibular triangle lymph node metastasis was occult in only 3 patients. Histological lymph node metastasis to the posterior triangle was found in 5.9% of patients with N0, 7.0% with N1, 37.5% with N2a and 36% with N2b-N3. Histological neck lymph node metastasis to the posterior triangle was found in 4.0% of patients without inferior jugular lymph node metastasis and 34.1% of patients with inferior jugular lymph node metastasis.


Lateral neck dissection was recommended to treat hypopharyngeal cancers of N0 and N1. N2 and N3 should be treated with neck dissection including II-V group lymph nodes. After lateral neck dissection, frozen section of the inferior jugular lymph node should be performed. If the result of the frozen section is positive, V group dissection should be performed.
