Objective: To assess the efficacy of ultrasound-guided thyroid fine-needle aspiration biopsies (USFNABs) performed in the office setting by an otolaryngologist and to evaluate the specimen adequacy of USFNABs performed in patients whose initial palpation-guided fine-needle aspiration biopsies (PGFNABs) were nondiagnostic.
Design: Retrospective chart review.
Setting: Royal Victoria Hospital-McGill University Health Centre, Montreal.
Methods: This is a retrospective analysis of 76 USFNABs performed by an otolaryngologist on consecutive patients over a 6-month period. Each patient had a previous nondiagnostic PGFNAB. Biopsies were performed using a 20-gauge fine needle with a Mylab25 Biosound Esoate ultrasound machine. Samples were then classified according to the adequacy of sample and pathologic findings.
Main Outcome Measure: Specimen adequacy rate.
Results: Sixty-six patients underwent 76 USFNABs. The sample included 57 females and 9 males (mean age 51.1 and 55.4 years, respectively). The specimen adequacy rate was 90.8% (69 of 76). Among the adequate specimens, 2 (2.6%) were malignant, 6 (7.9%) were suspicious for malignancy, 43 (56.6%) were benign, and 18 (23.7%) were follicular or Hurthle cell lesions (indeterminate).
Conclusion: Our experience demonstrates that USFNAB performed in the clinic by an otolaryngologist is a promising tool for improving specimen adequacy for nodules initially classified as nondiagnostic. USFNAB also avoids the need for radiologic consultation, thus improving efficacy in the workup of nodules.
