Abstract
Background: Head and neck cancers include cancers of the lips, mouth, nasal cavity, paranasal sinuses, pharynx and larynx. Most of these cancers are squamous cell carcinomas (SCCs). The presence of metastatic cervical lymphadenopathy is of particular importance as with every single nodal metastasis, survival of the patient is reduced by one half.
 Objective: To see the prevalence of metastatic neck node.
 Methods: The prospective cross-sectional clinical study was carried out in the Department of ENT and Head Neck Surgery, Combined Military Hospital, Dhaka during March’2018 to March, 2019. All 100 patients were included in this study and were treated at the Department of Otolaryngology of Combined Military Hospital, Dhaka.
 Results: Total 26 cases were found parotid among them 8(30.8%) in metastatic neck node and 18(69.2%) in without metastatic neck node. Total 10 cases were found paranasal sinuses among them 1(10.0%) in metastatic neck node and 9(90.0%) in without metastatic neck node. Which were statistically significant (p<0.05) between two groups.
 Conclusion: In this study observed that majority of metastatic neck node were found pyriform fossa, supraglottic larynx, base of tongue which were 68.2%, 68%, 77.8% respectively. In oral cavity and parotid site also found 48.1% and 30.8% metastatic neck node.

Summary
All 100 patients were included in this study and were treated at the Department of Otolaryngology of Combined Military Hospital, Dhaka. In this study performed bilateral neck dissection including the level V area for cN0 and cN+ cases with primary tumor (over T3) resection to pathologically evaluate the rate of level V metastases on bilateral sides. The prevalence and distribution of neck LNM were determined level by level for each primary site according to the results of the pathological analysis. The prevalence of pathological metastasis to level V lymph nodes on the ipsilateral and contralateral sides was investigated in all cases. Several predictive risk factors for level V metastasis were evaluated such as age, sex, primary site, T stage, N stage, degree of pathological differentiation and lymph node status of other levels (levels I–IV). Statistical analysis was performed using Fisher’s exact probability test (SPSS ver-23). p values of < 0.05 were considered statistically significant
