Abstract: Objective :To study features of cervical lymph node metastasis and application of neck dissection in surgical treatment of supraglottic carcinoma. Methods : A review of cervical lymph node metastasis of 210 patients with supraglottic carcinoma was performed. Results :The rate of cervical lymph node metastasis was 47.6% and occult metastatic rate was 32.4%; 535 metastatic lymph nodes were obtained in 420 neck dessection samples; Metastatic rate at different regions of the primary tumor included the metastasis rate of 51.9% for epiglotto-ventricular bands, 33.3% for epiglottis, 40.7% for ventricular fold and 77.8% for aryepiglottic fold, respectively; the metastatic rate for the primary tumor with different extents (T) included 14.7% for T,, 37.7% for TZ, 53.4% for T3 and 77.6% for TQ,respectively. The metastatic rate of the primary tumor with different grading (G) were G, with metastasis rate of 12.9%, GZ with 41.0% and G3 with 91.1%. Conclusions :The cervical lymph node metastasis of supraglottic carcinoma is closely associated with region, extent and grading of the primary tumor, metastaticlymph nodes were mostly located in,111level, radical neck dissection is commended for N+ pabent and supraomohyoid neck dissection seems justifiable for the treatment of No patient, especially fo G3,T3 and aryepiglottic fold carcinoma.
