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.
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.
Surgical techniques in parotid surgery have evolved in the last years with the use of neuromonitoring of the facial nerve and have become safer and less invasive. [19] After surgical removal of the parotid gland (parotidectomy), the auriculotemporal nerve is liable to damage and upon recovery it fuses with sweat glands. This can cause sweating ...
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 ...
Scrofula caused by NTM, on the other hand, responds well to surgery, but is usually resistant to antibiotics. [citation needed] The affected nodes can be removed either by repeated aspiration, curettage or total excision (with the risk in the latter procedure, however, often causing unsightly scarring, damage to the facial nerve, or both).
A fine needle aspirate can be done with simply a small bore needle and a small syringe (1 cc) that can generate rapid changes in suction pressure. Fine needle aspirate can be used to distinguish a cystic lesion from a lipoma. Both the surgeon and the pathologist must be familiar with the method of procuring, fixing, and reading of the slide.
Head and neck cancer is a general term encompassing multiple cancers that can develop in the head and neck region. These include cancers of the mouth, tongue, gums and lips ( oral cancer ), voice box ( laryngeal ), throat ( nasopharyngeal , oropharyngeal , [ 1 ] hypopharyngeal ), salivary glands , nose and sinuses .
