Fine-needle aspiration (FNA) is a diagnostic procedure used to investigate lumps or masses. In this technique, a thin (23–25 gauge (0.52 to 0.64 mm outer diameter)), hollow needle is inserted into the mass for sampling of cells that, after being stained , are examined under a microscope ( biopsy ).
–conducted to help the surgeon locate the tumor and address complications (i.e. the extent of the neoplasm and its resulting excision). Fine-needle aspiration - technique in helping the surgeon to physically diagnose the malignancy of the tumor; Neck dissection - only considered in the most extreme of cases before a parotidectomy.

It is important to note that a NIFTP diagnosis cannot be made on the basis fine needle aspiration alone. Evaluation of a surgical resection specimen is required to rule out invasive growth. If molecular studies are applied to the fine needle aspiration material, an RAS mutation is the most common identification. [4] [15] [16]
Diagnosis of benign lesions require a fine-needle-like aspiration biopsy. [13] With various benign lesions, most commonly the pleomorphic adenoma, there is a risk of developing malignancy over time. [13] As a result, these lesions are typically resected.
Fine needle aspiration cytology (FNAC) has a sensitivity and specificity percentages of 81% and 100%, respectively, in the histopathology of malignant cervical lymphadenopathy. [11] PET-CT has proven to be helpful in identifying occult primary carcinomas of the head and neck, especially when applied as a guiding tool prior to panendoscopy, and ...
Fine needle aspiration biopsy (FNA), operated in experienced hands, can determine whether the tumor is malignant in nature with sensitivity around 90%. [3] [4] FNA can also distinguish primary salivary tumor from metastatic disease. Core needle biopsy can also be done in outpatient setting.

[1] However, it is controversial: [ 11 ] it is recommended by some for the reason that a seroma can be a culture medium for bacteria, [ 12 ] whereas others advise it only for collection of excessive amounts of fluid, because even an aspiration carried out under aseptic conditions carries a certain ...
