Background: Palpable neck swellings include various non-neoplastic and neoplastic lesions of lymph node, salivary glands, thyroid and soft tissue. Fine needle aspiration cytology (FNAC) is the most cost-effective invasive pre-operative investigation, whose simplicity and safety justify its use for "selective" surgery in diagnosing different types of masses. The aim of this study is to evaluate the effectiveness of FNAC as a primary investigation tool in neck masses. The primary objective of the study was to assess the spectrum of head and neck masses and to determine the accuracy of FNAC in detection of various lesions in index medical college hospital and research Centre. Methods: The study included 510 patients presenting with palpable neck swelling in a tertiary care hospital from September 2015 to December 2016.
Results:The most frequent cause of neck swelling is lymphadenopathy 58.94%, followed by thyroid swelling 27.36%, soft tissue lesion 10.95% and salivary gland lesions 2.73%. The most common lesion in these patients was non-neoplastic followed by malignant neoplasm. FNAC is an important tool for preoperative clinical diagnosis of non-cystic neck masses with history of more than 3 months. Thus, it helps in planning the surgical management of neck masses and can be confirmed with HPE which is a "gold standard" for diagnosis. Conclusion: Fine needle aspiration cytology is a safe, simple and rapid method that can be done in diagnosing wide range of neck masses.
