How to effectively monitor the patient’s condition after surgery?

Although surgical treatment of thyroid nodules has been widely adopted in many hospitals due to advances in surgical techniques and medical equipment, it remains an invasive therapeutic approach associated with inherent risks and potential complications. Specific details are outlined below:

Effective Postoperative Monitoring of Clinical Condition

Postoperative Hemorrhage

Postoperative hemorrhage is a relatively common complication following thyroid nodule surgery. It frequently results from slippage or dislodgement of ligatures securing the superior thyroid artery or larger veins, as well as significant oozing from the cut surface of the glandular tissue. Such bleeding typically occurs within 12–48 hours postoperatively.

Superior Laryngeal Nerve Injury

Injury to the external branch of the superior laryngeal nerve may cause cricothyroid muscle paralysis, leading to voice pitch reduction. Injury to the internal branch impairs sensation in the laryngeal mucosa, resulting in aspiration—particularly during swallowing liquids—and subsequent coughing.

Recurrent Laryngeal Nerve Injury

Unilateral recurrent laryngeal nerve injury commonly causes hoarseness. Bilateral injury may lead to severe respiratory distress or even asphyxia.

Tetany (Hand-Foot Spasms)

Accidental removal, trauma, or compromised blood supply to the parathyroid glands during surgery can result in hypoparathyroidism and subsequent tetany. Clinically, most patients experience only paresthesia (pins-and-needles sensation) or muscular rigidity localized to the face, lips, or hands and feet.

Hypothyroidism

This condition often arises from excessive resection of thyroid tissue, but may also occur secondary to insufficient blood supply to residual thyroid tissue.

Postoperative Recurrence

Recurrence rates vary depending on the nature of the thyroid nodule. For simple goiter, recurrence typically manifests 6–10 years after surgery. In malignant thyroid nodules, recurrence rates differ according to the histopathological subtype of thyroid cancer. Differentiated thyroid carcinoma—including papillary and follicular carcinomas—is the most common clinical type; approximately 30% of such cases experience recurrence or metastasis, with the majority occurring within 10 years postoperatively.

The incidence of postoperative complications varies depending on the nature, size, and location of the thyroid nodule. Many thyroid nodules do not require surgical intervention. Small, nonfunctioning, benign nodules that do not necessitate surgery may instead be monitored through periodic follow-up examinations every 6–12 months.
