Thyroid Surgery: questions and answers

In detail

The surgeon identifies and protects the recurrent laryngeal nerves that control the voice box and the parathyroid glands that regulate calcium. In a total thyroidectomy the whole gland is removed and lifelong thyroid tablets are needed.

In a hemithyroidectomy only one lobe is taken out and many patients keep normal hormone levels. If cancer has spread to lymph nodes a neck dissection may be added. The wound is closed with dissolvable stitches and skin glue.

In detail

Guidelines list several situations where surgery is appropriate. These include nodules with Bethesda class V or VI cytology, indeterminate nodules not suitable for watchful waiting, compressive symptoms from a large goitre, and hyperthyroidism that does not respond to medical treatment.

Aesthetic concern from a visible neck swelling can also be a reason. The type of operation, total or partial, depends on the underlying condition and how much tissue is involved.

In detail

Guidelines recommend neck ultrasound for all suspected thyroid disease. FNA is indicated based on size and EU-TIRADS category: EU-TIRADS 5 nodules over 10 mm, EU-TIRADS 4 over 15 mm, EU-TIRADS 3 over 20 mm.

If cytology is indeterminate (Bethesda III or IV) and not suitable for surveillance, surgery may be advised. Vocal cord mobility is assessed before surgery if you have voice changes, cancer with suspected spread, or previous neck surgery. The surgeon also checks for bleeding disorders and calcium levels.

In detail

Evidence shows that for papillary microcarcinoma, active surveillance is an accepted alternative to immediate surgery. For benign nodules causing pressure symptoms, the compression will not improve without treatment and may worsen. In hyperthyroidism, uncontrolled hormone levels can affect the heart and bones.

If cancer has spread to lymph nodes, delay may allow further spread. The decision balances the natural history of your condition against the risks of surgery such as temporary voice change or low calcium.

In detail

Guidelines specify ultrasound for all patients with suspected nodular disease. FNA indications follow EU-TIRADS size cut-offs: EU-TIRADS 5 over 10 mm, EU-TIRADS 4 over 15 mm, EU-TIRADS 3 over 20 mm.

If TSH is low, a thyroid scan may be done to check for functioning nodules. CT or MRI is only used if there is concern about extension into the chest or nearby structures. Preoperative calcium and vitamin D levels help predict hypocalcemia risk. The anaesthesia team will review your fitness for general anaesthesia.

In detail

Evidence shows preoperative optimisation reduces complications. If you take thyroid hormone, continue the same dose unless your surgeon changes it. Blood thinners like aspirin or warfarin are usually stopped 5 to 7 days before surgery after consulting your cardiologist.

Herbal products that increase bleeding risk (garlic, ginkgo, ginseng) should be stopped two weeks prior. Vitamin D deficiency should be corrected if time permits, as low levels predict postoperative hypocalcemia. The anaesthetist will advise on your regular medicines on the morning of surgery.

In detail

General anaesthesia requires an empty stomach to reduce the risk of vomiting and aspiration into the lungs.

The anaesthesia team follows standard fasting guidelines: no solid food for six hours, no milk or opaque fluids for six hours, clear fluids (water, clear juice without pulp) may be allowed up to two hours before induction.

If you take regular medicines, the anaesthetist will tell you which to take with a sip of water on the morning of surgery. Do not chew gum or suck sweets during the fasting period.

In detail

Evidence shows many herbal products affect clotting or anaesthesia. Garlic, ginkgo, ginseng, and high-dose fish oil should be stopped at least two weeks before surgery. Blood thinners are usually stopped 5 to 7 days prior after consulting your prescribing doctor.

If you take thyroid hormone, continue the same dose unless your surgeon changes it. Calcium and vitamin D supplements may be started before surgery if your levels are low, as this reduces postoperative hypocalcemia risk. The anaesthetist needs a complete list to avoid drug interactions.

In detail

Diabetes and high blood pressure are common and do not stop thyroid surgery, but they need good control before the operation to lower infection and wound-healing risks.

Blood-thinning medicines such as aspirin, clopidogrel, warfarin, or newer anticoagulants increase bleeding risk during and after thyroidectomy because the thyroid has a very rich blood supply.

The team usually asks you to stop or bridge these medicines a few days before surgery, depending on why you take them. The anaesthetist will also check your heart and kidney function. All changes are made in writing and explained to you and your attendant before admission.

In detail

The breathing tube used during general anaesthesia often leaves a sore throat for a few days, especially when swallowing. The neck incision may feel tight or tender. Studies show most patients manage with simple pain relief such as paracetamol.

The collodion dressing on the wound can harden and cause a pulling sensation when you swallow or extend your neck, peaking around three weeks and fading over three to six months.

Seroma, a collection of clear fluid under the wound, can cause a feeling of fullness but usually resolves on its own. If a larger seroma forms, the team can aspirate it under sterile conditions.

In detail

Studies show temporary voice change occurs in about one in ten patients and usually resolves in weeks. Lasting voice problems affect up to one in twenty-five.

Temporary low calcium happens in roughly twenty to thirty percent after total thyroidectomy; lasting low calcium is about one percent. Bleeding needing re-operation is under one percent. Infection is rare. Your surgeon identifies the recurrent laryngeal nerve and parathyroid glands during the operation to minimise these risks.

In detail

Evidence shows re-operation and large thyroid specimens raise the chance of nerve injury and low calcium. Graves' disease and low pre-operative vitamin D are independent predictors of long-term low calcium. Obesity and a short neck can make the anatomy harder to see.

Blood-thinning medicines and uncontrolled blood pressure increase bleeding risk. The team uses careful dissection, nerve identification, and modern energy devices to lower these risks regardless of the factors present.

In detail

During surgery, the surgeon examines the thyroid and nearby lymph nodes. If cancer is suspected, frozen section or final pathology checks margins and nodes.

After total thyroidectomy, you will need lifelong thyroid hormone tablets; the dose is adjusted by checking TSH every two months until stable, usually in four to five months. After hemithyroidectomy, about 60 to 70 percent of patients keep normal thyroid function without tablets.

Calcium levels are checked at 24 hours and at follow-up. Voice is assessed clinically and by laryngoscopy if needed. For cancer, long-term follow-up includes thyroglobulin blood tests and neck ultrasound to watch for recurrence. Studies show excellent outcomes for low-risk papillary cancer with over 98 percent disease-specific survival at five years.

In detail

You will be awake and able to eat and drink a few hours after surgery. Walking and normal light activity are encouraged the same evening. Heavy lifting, swimming, and soaking the wound are avoided for one week.

Temporary hoarseness usually improves within a few weeks but can take up to six months. Temporary low calcium is managed with supplements for at least 10 days.

The wound dressing hardens and peaks at three weeks, causing some tightness when swallowing, which fades over three to six months. Seroma may appear but often resolves without treatment. Nerve recovery, if injured, typically occurs between four and six weeks for transient injury.

In detail

The sore throat comes from the breathing tube and settles in two to three days. Hoarseness from nerve irritation usually improves in three to four weeks but can take six months.

Low calcium symptoms (tingling, cramps, Chvostek's or Trousseau's signs) typically appear twenty-four to forty-eight hours after surgery. Bleeding is most likely in the first six hours but can happen up to twenty-four hours.

A deep haematoma may not cause obvious swelling but can cause breathing trouble. Infection is rare but would show as increasing redness, heat, or pus at the wound.

In detail

You can shower after 24 hours, letting water run over the dressing, then pat it dry gently. Avoid direct sunlight on the healing scar for the first year; use sunscreen or a scarf.

The wound may feel tight and hard at three weeks, especially when swallowing or extending the neck; this softens over three to six months. If a seroma (fluid collection) forms, it usually absorbs on its own. Larger seromas can be aspirated under sterile conditions.

Drains, if placed, are removed before discharge. Watch for increasing redness, heat, pus, or opening of the wound, which are rare signs of infection.

In detail

After thyroidectomy, the incision is closed with dissolvable stitches and skin glue or a waterproof dressing. Evidence shows patients are generally eating, drinking, and doing normal activities the night of the operation.

The glue or collodion on the wound turns white and curls at the edges in about 5 to 7 days. Keeping the area dry for the first 24 hours helps the seal form properly. Your nursing team will check the dressing before you leave and advise when you can remove it.

In detail

Evidence shows patients are encouraged to eat, drink, walk and do normal activities the night of the operation. A sore throat when swallowing is common for a few days. Soft foods such as khichdi, dal, curd, soups or mashed vegetables reduce discomfort.

Cold or room-temperature liquids may feel soothing. Avoid very hot, spicy or coarse foods that could irritate the throat. If you had a total thyroidectomy, your surgeon may start calcium and vitamin D supplements to prevent low blood calcium; take them with food as directed. Normal medications can usually be resumed the day after surgery.

In detail

Thyroid function tests are part of the standard workup. A subnormal TSH suggests a hyperfunctioning nodule, which may be treated with radioiodine instead of surgery. Normal TSH with a suspicious nodule on ultrasound usually leads to a fine-needle aspiration biopsy to check for cancer.

After total thyroidectomy, you will need lifelong thyroid hormone replacement, and the dose is adjusted based on TSH levels checked every few months until stable. The surgeon uses these values along with ultrasound findings and biopsy results to decide the type and extent of surgery.

In detail

Guidelines say ultrasound of the thyroid and neck compartments should be done for all suspected nodular disease. Nodules are graded using EU-TIRADS. Biopsy size cut-offs are: EU-TIRADS 5 nodules larger than 10 mm, EU-TIRADS 4 larger than 15 mm, EU-TIRADS 3 larger than 20 mm.

Smaller or low-risk nodules may only need follow-up scans at six months to five years depending on the category. If the first biopsy is non-diagnostic or shows Bethesda class III, a repeat biopsy is considered. Core-needle biopsy is a second-line option for specific situations. The decision is shared with you after explaining the risk of malignancy.

In detail

Ultrasound looks for suspicious features such as irregular margins, microcalcifications, taller-than-wide shape, and marked hypoechogenicity. EU-TIRADS 5 nodules have a high risk of malignancy, while EU-TIRADS 2 and 3 are usually benign.

Fine-needle aspiration gives a Bethesda classification: category II is benign, category V and VI are suspicious or malignant, and categories III and IV are indeterminate. For indeterminate nodules, molecular testing or repeat biopsy may be used.

In studies, papillary thyroid cancer accounts for about 84 percent of thyroid cancers found. The final diagnosis is made by a pathologist examining the tissue after surgery if surgery is performed.

• In studies, papillary thyroid cancer accounts for about 84 percent of thyroid cancers found.

In detail

Guidelines list specific indications: Bethesda V or VI cytology, symptomatic benign nodules, compressive symptoms like dysphagia or dyspnea, toxic nodules, and nodules growing despite surveillance. For small, low-risk papillary microcarcinomas, active surveillance may be offered as an alternative.

Your surgeon also checks vocal cord function before surgery if you have voice changes or a high-risk cancer. The decision is made in a shared discussion with you, weighing the risks of surgery against the risks of observation.

In detail

Evidence shows that for very low-risk papillary microcarcinomas, active surveillance with regular ultrasound is a recognised option. For benign solid nodules causing symptoms, thermal ablation can shrink the nodule without a neck incision. For overactive solitary nodules, radioiodine is an established alternative.

For cystic nodules, ethanol ablation is often first-line. These options depend on the nodule type, size, location, and your preferences. Not all techniques are suitable for every patient, and long-term follow-up is still required. Your surgeon will explain which alternatives apply to your specific diagnosis.

In detail

Cost factors include whether you need a total thyroidectomy, hemithyroidectomy, or neck dissection. Conventional open surgery is generally less costly than endoscopic or robotic approaches. Room choice, length of stay, and any post-operative calcium or hormone medication also affect the total.

The hospital accepts RGHS, MAA Yojana, CGHS, and private insurance TPAs, which may cover part or all of the procedure. The basic procedure cost excludes room and facility charges, which can increase the overall bill significantly.

In detail

The base cost varies with the type of thyroidectomy such as total thyroidectomy, hemithyroidectomy, or neck dissection. Evidence shows that conventional open surgery is generally less costly than endoscopic or robotic approaches.

Additional charges often apply for the room category you choose, pre-operative investigations, histopathology of the removed tissue, and any special equipment like intraoperative nerve monitoring.

If you have a large goitre, cancer requiring lymph node removal, or need re-operation, the procedure takes longer and uses more resources, which increases the total. Complications such as bleeding or prolonged low calcium may extend your stay and add medication or ICU costs.
