Abstract
OBJECTIVE Functional neck dissection was first described by Bocca and Pignataro in 1967. It has been used in clinical practice for years, but remains controversial among neck-surgery experts. This study was designed to evaluate indications and curative effects of functional-neck dissection (FND). METHODS One hundred and fifty-two cases which underwent FND were reviewed with an analysis of pathological specimens and follow-up datas. RESULTS The series of FND included 20 cases of tongue carcinoma, 23 cases of larynx carcinoma, 96 cases of thyroid papillary adenocarcinoma, 9 cases of foilicular adenocarcinoma and 4 cases of medullary adenocarcinoma; the five-year recurrence rate for tongue carcinoma was12.5%, 14.3%, 400% and for a larynx carcinoma was 20.0%, 16.7%, 50.0% in No stage, N, stage, N2~ stage, respectively. The 5-year recurrence rate of thyroid papillary adenocarcinoma was 6.5%, 7.1% in Nla, Nlb, respectively. CONCLUSION Functional neck dissection is indicated in early and low malignant head and neck neoplasms and results in satisfactory curative effects.
