Thyroid Surgery in Pokhara: Thyroidectomy Procedure and Recovery Guide

Nepal has one of the highest rates of goiter (enlarged thyroid) in South Asia, driven historically by iodine deficiency in the food supply. While universal iodized salt programs have reduced endemic goiter, thyroid surgery remains common — for cancer, large compressive goiters, hyperthyroidism unresponsive to medication, and suspicious thyroid nodules. A&B International Hospital in Pokhara performs thyroid surgery with meticulous attention to nerve preservation and calcium management.

Which Thyroid Conditions Require Surgery?

Not all thyroid conditions need surgery. Medical management — anti-thyroid drugs, radioactive iodine, thyroid hormone replacement — addresses many thyroid disorders effectively. Surgery becomes necessary when these approaches are inadequate or inappropriate, or when structural problems require removal.

Thyroid cancer

Thyroid cancer is the most common endocrine malignancy. Papillary thyroid carcinoma (the most common type in Nepal) has an excellent prognosis when detected and treated early. Surgery is the primary treatment — typically total thyroidectomy for tumors larger than 1 cm, followed by radioactive iodine ablation in many cases.

Suspicion of cancer arises when:

• Fine needle aspiration cytology (FNAC) reports malignant or suspicious cells
• Ultrasound shows specific high-risk features: irregular margins, microcalcifications, taller-than-wide shape, absent halo, abnormal cervical lymph nodes
• Rapid nodule growth
• Hoarseness suggesting recurrent laryngeal nerve involvement

Large goiter (multinodular goiter)

A multinodular goiter may require surgery when it causes compressive symptoms: difficulty swallowing (dysphagia), sensation of pressure in the neck, shortness of breath when lying down (tracheal compression), or voice change from recurrent laryngeal nerve pressure.

Toxic nodule or Graves’ disease

Hyperthyroidism (overactive thyroid) caused by a single toxic nodule (Plummer’s disease) or diffuse toxic goiter (Graves’ disease) that fails medical therapy or where radioactive iodine is contraindicated (large goiter, eye disease, pregnancy planning) is treated surgically.

Indeterminate or suspicious FNAC result

When FNAC returns an indeterminate or follicular neoplasm result (Bethesda category III–IV), diagnostic thyroid lobectomy (hemi-thyroidectomy) is performed to obtain definitive histology. If cancer is confirmed on frozen or paraffin section, completion thyroidectomy follows.

What Is the Difference Between Total and Partial Thyroidectomy?

Total thyroidectomy: Removal of the entire thyroid gland. Performed for thyroid cancer (most types), large bilateral multinodular goiter, and bilateral Graves’ disease. Requires lifelong thyroid hormone replacement after surgery.

Hemithyroidectomy (thyroid lobectomy): Removal of one lobe plus the isthmus. Performed for a single nodule, a toxic solitary nodule, or diagnostic purposes for indeterminate FNAC. The remaining lobe may produce sufficient thyroid hormone to avoid replacement in some patients — monitored with TSH post-operatively.

Near-total thyroidectomy: Removal of all thyroid tissue except a small remnant left to protect the recurrent laryngeal nerve and parathyroid glands. Less commonly performed now — total thyroidectomy by an experienced surgeon achieves the same nerve and parathyroid preservation with better radicality.

What Happens During the Thyroid Surgery Procedure?

Thyroidectomy is performed under general anesthesia through a transverse (horizontal) incision made in a natural skin crease at the base of the neck. Modern technique makes scars well-concealed and narrow.

Surgical steps:

1. The patient is positioned supine with the neck gently extended.
2. A 4–6 cm transverse incision is made at the skin crease approximately 2 cm above the clavicles.
3. The platysma muscle is divided and subplatysmal flaps raised to expose the thyroid.
4. The anterior strap muscles (sternohyoid and sternothyroid) are separated in the midline.
5. The thyroid lobe is rotated medially to expose the posterior surface.
6. Critical step — recurrent laryngeal nerve identification: The recurrent laryngeal nerve (RLN) runs in the tracheoesophageal groove behind the thyroid. It controls the vocal cord. Injury causes hoarseness or, if bilateral, breathing difficulty. The nerve is identified under direct vision and protected throughout the dissection.
7. Parathyroid gland preservation: The four parathyroid glands sit on the posterior surface of the thyroid and regulate blood calcium. They are identified, their blood supply preserved, and if devascularized, auto-transplanted into the sternocleidomastoid muscle.
8. The thyroid is removed after ligation of superior and inferior thyroid vessels.
9. A drain may be placed if bleeding risk warrants it.
10. Wound closed in layers.

What Is Recurrent Laryngeal Nerve Monitoring?

Intraoperative neuromonitoring (IONM) of the recurrent laryngeal nerve uses electrical stimulation probes during surgery to confirm nerve function continuously. An endotracheal tube electrode detects voice cord movement in response to stimulation.

IONM does not prevent nerve injury but:

• Confirms nerve identification at the start of surgery
• Alerts the surgeon immediately if traction or dissection affects nerve conduction
• Confirms nerve integrity at the end of surgery
• Reduces permanent RLN injury rates in experienced surgical units

What Happens to Calcium After Thyroid Surgery?

Hypoparathyroidism — low function of the parathyroid glands — is the most common complication after total thyroidectomy. The parathyroid glands regulate blood calcium. When their blood supply is disrupted during surgery, temporary or permanent hypoparathyroidism can result.

Symptoms of low calcium (hypocalcemia):

• Tingling or numbness around the mouth, fingertips, and toes (perioral and acral paresthesia)
• Muscle cramps, particularly in the hands (carpopedal spasm)
• Facial muscle twitching (Chvostek’s sign)
• In severe cases: tetany, muscle spasm, and seizures

Post-operative calcium monitoring:

• Serum calcium checked at 6 hours post-op and before discharge
• Oral calcium carbonate (1g three times daily) prescribed routinely after total thyroidectomy for the first 2–4 weeks
• Calcitriol (vitamin D analog) added if calcium drops below 2.0 mmol/L or symptoms develop
• Calcium levels normalize over 4–12 weeks as parathyroid function recovers in most patients

Permanent hypoparathyroidism (persisting beyond 6 months) occurs in approximately 1–5% of total thyroidectomies by experienced surgeons and requires ongoing calcium and vitamin D supplementation.

Will I Need Thyroid Hormone Replacement After Surgery?

After total thyroidectomy: Yes, without exception. The thyroid is the sole source of thyroxine (T4) in the body. Levothyroxine (synthetic T4) is prescribed daily, starting the day after surgery.

• Initial dose is calculated by body weight (approximately 1.6 mcg/kg/day).
• TSH level is checked at 4–6 weeks to adjust the dose.
• In thyroid cancer patients, the levothyroxine dose is often set to mildly suppress TSH, reducing the growth stimulus for any residual cancer cells.

After hemithyroidectomy: Approximately 70–80% of patients do not require replacement. The remaining lobe compensates in most cases. TSH is checked 6 weeks after surgery to determine whether replacement is needed.

What Is the Recovery After Thyroid Surgery?

Days 1–2: Neck stiffness and soreness, mild sore throat from endotracheal tube, voice may sound different temporarily (normal swelling, not nerve injury). Most patients eat and drink the same day.

Days 3–5: Discharge home typically by day 1–2. Voice hoarseness may persist for 1–2 weeks if nerve was stretched (not severed).

Week 1–2: Avoid neck flexion and extension extremes. Restrict driving for 1 week. Desk work resumable in 1–2 weeks.

Scar healing: The transverse neck scar is treated with silicone gel or silicone sheets from 2 weeks post-op, once the wound is fully closed. Good scar healing results in a narrow, flesh-colored line that becomes inconspicuous in most patients by 3–6 months.
