High-Speed Pneumatic Drill for Biopsy of Thyroid Lesions

Arch Surg. 1974;108(5):744-745. doi:10.1001/archsurg.1974.01350290106021

Diagnoses were obtained in 54 patients with different thyroid disorders with use of a high-speed pneumatic drill biopsy machine. The procedure requires only a small, skin incision and can be safely performed as an outpatient procedure with the patient under local anesthesia. Because of the small size of the tissue obtained, the processing is rapid and a histological report can be obtained within 24 hours. The tissue is not traumatized and the cellular architecture is well maintained in the specimen. The drill-biopsy accuracy rate was 92.6%, whereas the clinical accuracy was 80%. No complications were encountered in the study.

We believe this study indicates that drill biopsy is an important diagnostic tool that can be safely recommended before performing major thyroid surgery.
