What this trial studies

This clinical study investigates the timing of carbon nanoparticles injection in patients undergoing surgery for papillary thyroid cancer. Participants will receive injections either preoperatively or intraoperatively to assess the impact on surgical outcomes and complications. The study aims to minimize common postoperative complications such as hypoparathyroidism and recurrent laryngeal nerve injury. By utilizing ultrasound guidance for precise injection, the research seeks to improve the safety and effectiveness of thyroid cancer surgeries.

Who should consider this trial

Good fit: Ideal candidates are adults with a confirmed diagnosis of papillary thyroid cancer, requiring total thyroidectomy, and with tumors less than 4 cm in diameter.

Not a fit: Patients with a history of prior thyroid surgery, those under 16 years of age, or individuals with certain tumor characteristics may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce postoperative complications and improve the quality of life for patients with thyroid cancer.

How similar studies have performed: While the use of carbon nanoparticles in surgical settings is emerging, this specific approach to timing and application in thyroid cancer treatment is relatively novel and has not been extensively tested in prior studies.

Eligibility criteria

Inclusion Criteria:

* Preoperative pathological assessment indicated the presence of thyroid cancer with a maximum diameter of less than 4 cm.
* Postoperative pathological evaluation confirmed bilateral thyroid cancer or lateral lymph node metastasis.
* Vocal cord examination conducted one week prior to surgery revealed no abnormalities.
* The patient had no history of prior thyroid surgery and required a total thyroidectomy.
* Blood pressure was stably controlled.
* The patient regained consciousness and was able to communicate normally.

Exclusion Criteria:

* A documented history of thyroid surgery.
* Age under 16 years.
* Known allergies to the medications under investigation or an inability to tolerate surgical intervention.
* Presence of a retrosternal thyroid tumor.
* Tumor invasion of the parathyroid glands and/or the recurrent laryngeal nerve during surgical procedures.
* Postoperative pathology suggestive of medullary carcinoma or undifferentiated carcinoma.
* Development of a postoperative tracheal fistula.
