The Effectiveness of Fine-Needle Aspiration Conducted by The Otolaryngologists / 대한이비인후과학회지

ABSTRACT

BACKGROUND AND OBJECTIVES: To investigate the effectiveness of fine needle aspiration (FNA) conducted by the otolaryngologists, we compared the ultrasound (US)-guided FNA results conducted by a radiologist (RD-US), the US-guided FNA results (ENT-US), and the palpation guided FNA results (ENT-palpation) conducted by an otolaryngologist. SUBJECTS AND METHOD: 1646 patients who underwent FNA were classified according to the site and periods of investigation (2007-2015), and their sampling adequacy was retrospectively reviewed. They were also divided into three groups (ENT-US, ENT-palpation, and RD-US); each group was then investigated for sampling adequacy. Results of further surgical excisional biopsy were compared with the those of the FNA results to investigate the diagnostic accuracy of all three groups. RESULTS: The sampling adequacy identified by the groups showed the result of ENT-US at 87.9%, ENT-palpation at 87.1% and RD-US at 91.3%. The periodical inadequacy rate failed to show any significant differences between the groups. The sensitivity of ENT-palpation was lower than other two groups. Diagnostic accuracy identified by the groups showed the result of ENT-US at 95.2%, ENT-palpation at 93.6%, and RD-US at 97.4%. CONCLUSION: FNA performed by otolaryngologists demonstrates the effectiveness of diagnosis and treatment, and that doing so would improve economic efficiency. Therefore, it is recommended that well-trained otolaryngologists conduct FNA actively.
