Comparison of thinprep needle rinse samples versus direct smear techniques for fine neddle aspiration biopsies of head and neck lesions - Essay Example As a result, the pathologists and clinicians are to depend on the conveniences of a particular method that is most pertinent to the circumstance. A series of researches was led on the comparative diagnostic accuracy of the two techniques of FNA and their popularity among the clinicians and the pathologists (Frost et al, 1998). An analysis of the studies that have been led on the evaluation and the development of the techniques of Fine Needle Aspiration show an encouraging support for the ThinPrep technique of Fine Needle Aspiration Biopsies and trace the significant attempts in avoiding the pitfalls in the technique. In general, researchers are of the opinion that the accuracy of FNA at any site in the head and neck depends on both the skill and knowledge of the sites of the individual who will perform the FNA biopsies. As Layfield (2007) says, ‘Studies have shown that FNA is most accurate when the individual interpreting the FNA is the same individual who obtained the aspirate material’ (p. 798). In order to evaluate the performance of the FNA at the sites in the head and neck studies have had to revolve around the following questions: As far as the procedure of biopsy involves the obtainment of tissue, cell, or other specimen for diagnostic purposes, Fine Needle Aspiration has always played a crucial role as an initial technique of collecting them from a number of sites of human body. Indeed FNA is applied at a number of sites within the head and neck. The pressing appeal of the technique lies in several factors such rapidity, inexpensiveness, high convenience, low morbidity and necessarily in a relatively high diagnostic accuracy (Lester 2007). The amenability that areas in the head and neck show to this technique is mainly due to its capability to overcome the structural obstructions and barriers of the sites such as
