CONCLUSION: The low incidence of metastases in levels I and IIB in patients with hypopharyngeal cancer in cases of clinical N0 and N+ neck and the fact that all patients with metastases in levels I and IIB received postoperative radiotherapy justifies the preservation of levels I and IIB in patients with hypopharyngeal cancer to improve functional results and reduce the operating time.
OBJECTIVES: Neck dissection of levels I and IIB is technically demanding due to the complex local anatomy and can cause several comorbidities. Therefore the aim of the study was to analyze whether levels I and IIB have to be dissected in patients with hypopharyngeal cancer.
METHODS: This was a retrospective analysis of all patients who underwent primary surgical treatment for hypopharyngeal cancer and neck dissection, with evaluation of the incidence of metastases in levels I and IIB in cases of cN0 and cN+ neck.
RESULTS: None of the patients with cN0 neck but 2/33 patients with cN+ neck had metastases in level I. Metastases in level IIB were detected in 1/14 patients with cN0 neck and 2/36 patients with cN+ neck. All patients with metastases in levels I and IIB received postoperative radiotherapy due to the N2b and N2c status.
