Objective:
To evaluate the application value of preoperative ultrasound-guided drawing for locating thyroid micronodule in surgery.
Methods:
A total of 88 patients (with 137 thyroid micronodules) who underwent thyroid surgery was included in the prospective study. Preoperative thyroid ultrasound was conducted in all patients. Select criteria: the maximum diameter of nodule ≤ 1 cm. All patients were randomly divided into two groups: 46 patients (68 micronoduls) in experimental group with ultrasound-guided drawing location of thyroid micronodule and 42 patients (69 micronoduls) in control group without ultrasound-guided drawing location of thyroid micronodule.
Results:
All thyroid micronodules of experimental group were found quickly and accurately in surgery, and 4 micronodules in 4 patients of control group were not found in surgery. US examinations 3 months after surgery showed that all micronodules in experimental group were completely removed and 4 micronodules in control group retained.
Conclusion:
Ultrasound-guided drawing is a useful technique for locating and searching accurately thyroid micronodule in surgery.
