ABSTRACT
Objectives/Hypothesis: There is no actual count of lymph nodes which proves that this neck dissection is adequate. The aim of this study is to know total yield of lymph nodes in neck dissection level I–III that is supraomohyoid type in patients having head and neck cancers especially oral cavity and parotid gland cancers.
Study Design: Retrospective single-institution analysis.
Methods: All the patients who were diagnosed with head and neck cancer and who go through supraomohyoid neck dissection level I–III from 2016 to 2022 at HMC Peshawar were included in this study.  Patients with radiographic and clinical evidence of lymphadenopathy prior to surgery were eliminated, as was any patient whose pathology report indicated they had an unknown number of lymph nodes. Gender, age, tumor sub site, stage, surgeon, LNY were recorded.
Results:  85 individuals with level I–III neck dissections fulfilled the study’s inclusion requirements. In our study maximum LNY was 18-24 in 47 patients (55.29 percent) in which 25 patients with age in between (61-85), and 19 patients with age (31-60) and <30 were only 3 patients with p value=0.43.Out of 47 patients 32 were female and 15 male with p value=0.7.
Conclusions:  This study shows that atleast more than 18 lymph nodes should be dissected in supraomohyoid neck dissection in head and neck squamous cell CA patients to call it an effective neck dissection.
Key Words: Lymph node yield, supraomohyoid, level I–III neck dissection.
