Expert Total and Partial Thyroidectomy with Intraoperative Nerve Monitoring and Meticulous Parathyroid Preservation at Shree Hospitals
Thyroid surgery is the surgical removal of all or part of the thyroid gland - the butterfly-shaped endocrine gland at the base of the neck that produces hormones regulating metabolism, heart rate, and body temperature. Operations range from hemithyroidectomy (removal of one lobe) to total thyroidectomy (removal of the entire gland). Thyroid surgery at Shree Hospitals is performed by specialist head and neck surgeons with dedicated expertise in thyroid and parathyroid surgery, using intraoperative recurrent laryngeal nerve (RLN) monitoring as standard, meticulous parathyroid gland identification and preservation, and minimally invasive approaches where oncologically appropriate - minimising the risk of the most serious complications of thyroid surgery.

What is Thyroid Surgery and When Is It Needed?
The thyroid gland sits at the front of the neck below the larynx (voice box), wrapped around the front and sides of the trachea (windpipe), with the recurrent laryngeal nerves (RLN) - which control the voice - running in the groove between the trachea and oesophagus on each side. The parathyroid glands (four small calcium-regulating glands, each about the size of a grain of rice) are located on the back of the thyroid lobes. This anatomical proximity makes thyroid surgery technically demanding - the twin risks of RLN injury (causing hoarseness or loss of voice) and parathyroid damage (causing hypocalcaemia and symptomatic low calcium) are the most significant complications, and their prevention requires meticulous surgical technique and intraoperative nerve monitoring.
Thyroid surgery is indicated for several conditions. Thyroid nodules with suspicious features on ultrasound or fine needle aspiration cytology (FNAC) (Bethesda Class III, IV, V, or VI) require surgery for diagnosis or treatment. Thyroid cancer - including papillary thyroid cancer (PTC), follicular thyroid cancer (FTC), Hurthle cell carcinoma, medullary thyroid cancer (MTC), and anaplastic thyroid cancer - requires total thyroidectomy (with central compartment neck dissection if lymph nodes are involved) as the primary surgical treatment. Multinodular goitre causing compressive symptoms (dysphagia, dyspnoea, voice change, or retrosternal extension) requires surgical decompression. Hyperthyroidism (Graves' disease or toxic multinodular goitre) resistant to medical management or radioiodine is treated by total thyroidectomy. A solitary thyroid nodule deemed indeterminate on cytology (Bethesda III - atypia of undetermined significance) requires hemithyroidectomy for definitive histological diagnosis.
At Shree Hospitals, every patient being considered for thyroid surgery undergoes a structured pre-operative assessment: thyroid function tests, ultrasound of the thyroid and neck nodes, FNAC of any nodule requiring cytological assessment, indirect laryngoscopy (to confirm pre-operative vocal cord function), CT neck and thorax where retrosternal extension or malignancy with bulky nodal disease is suspected, and calcium and PTH levels. The extent of surgery is determined by the underlying diagnosis. Intraoperative RLN monitoring using a dedicated nerve monitoring system (with the endotracheal tube electrode touching the vocal cords) is used in all thyroid operations as standard.
Who Needs Thyroid Surgery?
- Thyroid cancer (all types): total thyroidectomy is the standard surgery, with neck dissection for involved lymph nodes
- Suspicious thyroid nodule (Bethesda IV, V, VI on FNAC): surgery for diagnosis and definitive treatment
- Indeterminate nodule (Bethesda III): hemithyroidectomy for definitive histology
- Symptomatic goitre causing swallowing difficulty, breathing difficulty, voice change, or neck compression
- Retrosternal goitre with thoracic inlet compression
- Hyperthyroidism (Graves' disease or toxic MNG) when medical therapy or radioiodine is not appropriate or has failed
- Hyperfunctioning ("hot") thyroid nodule on nuclear medicine scan in patients not suitable for radioiodine
Is Thyroid Surgery Right for You?
- Your thyroid nodule FNAC is Bethesda III, IV, V, or VI and surgery has been recommended
- You have confirmed or suspected thyroid cancer on imaging and cytology
- Your goitre symptoms (difficulty swallowing, breathlessness, or voice change) are impacting daily function
- Radioiodine therapy is not appropriate for you (large goitre, compressive symptoms, pregnancy, failure of previous radioiodine)
- You understand the risks of RLN injury and hypocalcaemia and have discussed them with your surgeon
- Your pre-operative vocal cord examination (indirect laryngoscopy) has confirmed normal bilateral vocal cord mobility
What Are the Critical Risks of Thyroid Surgery?
- Recurrent laryngeal nerve (RLN) injury: The RLN runs millimetres from the thyroid and controls the vocal cord on each side. Temporary RLN injury (neuropraxia from traction) occurs in up to 5% of cases and resolves over weeks to months. Permanent RLN injury results in hoarseness or voice change (unilateral) or, very rarely with bilateral injury, breathing difficulty requiring tracheostomy. Intraoperative nerve monitoring significantly reduces but does not eliminate this risk
- Hypoparathyroidism: Accidental removal or devascularisation of all four parathyroid glands during total thyroidectomy causes hypocalcaemia (low blood calcium), presenting with tingling around the mouth, fingertip paraesthesia, and in severe cases muscle cramps and tetany. Temporary hypocalcaemia is common; permanent hypoparathyroidism requiring lifelong calcium and vitamin D supplements occurs in 1 to 3% of total thyroidectomies in expert hands
Intraoperative RLN monitoring and meticulous parathyroid preservation at Shree Hospitals minimise the key risks of thyroid surgery, delivering safe outcomes for thyroid cancer and goitre patients.
Our head and neck surgery team at Shree Hospitals uses nerve integrity monitoring (NIM), harmonic scalpel haemostasis, and precise parathyroid identification and auto-transplantation techniques to protect the structures adjacent to the thyroid gland and deliver safe surgical outcomes in all thyroid operations from hemithyroidectomy to complex re-do thyroid surgery and cancer resection with neck dissection.

Our Approach To Thyroid Surgery
At Shree Hospitals, every thyroid surgery is planned around three principles: accurate pre-operative diagnosis, complete oncological resection where cancer is present, and maximum protection of the recurrent laryngeal nerves and parathyroid glands.
24×7 Emergency Care
Complete Pre-Operative Workup
Every patient undergoes thyroid ultrasound with FNAC of any nodule requiring cytological assessment, reported using the Bethesda System for Reporting Thyroid Cytopathology (Bethesda I to VI). Thyroid function tests (TSH, T3, T4) determine if the patient is hyperthyroid (requiring pre-operative antithyroid drug optimisation with carbimazole and beta-blocker). Pre-operative indirect laryngoscopy confirms bilateral vocal cord mobility - a mandatory step before thyroid surgery, both to document pre-existing voice problems and to confirm the nerve is functioning before placing it at risk. CT neck and thorax is arranged for large goitres with retrosternal extension, fixed masses, or thyroid cancer with suspected bulky nodal disease. Calcium and PTH levels are checked as a baseline before total thyroidectomy.
Intraoperative Recurrent Laryngeal Nerve
Monitoring Intraoperative nerve monitoring (IONM) using a NIM (Nerve Integrity Monitor) system with a dedicated electromyography (EMG) endotracheal tube (the tube electrodes lie against the vocal cords to record the EMG signal generated by RLN stimulation) is used in all thyroid operations as standard at Shree Hospitals. The RLN is identified, stimulated and confirmed functional at the start of dissection, continuously monitored during thyroid mobilisation and ligation of the superior and inferior thyroid artery branches, and re-stimulated and confirmed after thyroid lobe removal. A loss of signal on IONM alerts the surgeon to RLN compromise before permanent injury can occur, allowing the operative strategy to be immediately modified (abandoning ipsilateral nerve dissection if necessary). IONM has been shown to significantly reduce permanent RLN injury rates in experienced hands.
Parathyroid Identification and Preservation
Identification and preservation of all four parathyroid glands is a core surgical objective in every thyroid operation, and particularly in total thyroidectomy. Each parathyroid gland is identified, its vascular pedicle to the thyroid capsule or inferior thyroid artery is preserved, and the gland is protected throughout thyroid mobilisation. If a parathyroid gland is inadvertently devascularised or removed with the thyroid specimen (confirmed by sending the tissue for frozen section), it is auto-transplanted into the sternocleidomastoid muscle (morselised into 1mm fragments and implanted into muscle pockets) to preserve parathyroid function. Post-operative serum calcium and PTH are checked at 4 to 6 hours and the following morning. Calcium and vitamin D supplements are given routinely after total thyroidectomy and are weaned progressively as parathyroid function recovers.
Thyroid Cancer Surgery and Neck Dissection
For confirmed thyroid cancer, the extent of surgery is determined by the cancer type, size, and lymph node status. Total thyroidectomy is standard for all papillary cancers over 1cm, follicular cancers, and medullary cancers. Central compartment neck dissection (Level VI) - removal of the central neck lymph nodes between the carotid arteries - is performed for clinically node-positive disease and for medullary thyroid cancer (where central node involvement is common even without palpable nodes). Lateral neck dissection (Levels II to V) is performed for confirmed lateral lymph node metastasis on pre-operative imaging. After total thyroidectomy for papillary or follicular cancer, the patient is referred for radioactive iodine (RAI) ablation coordinated with the nuclear medicine and endocrinology teams. Long-term TSH suppression with levothyroxine is maintained post-operatively as per the ATA (American Thyroid Association) risk stratification guidelines.

Step by Step process of Thyroid Surgery
Step 1 - Multi-Disciplinary Pre-Operative Assessment
All patients with a suspected or confirmed thyroid cancer are discussed at the Thyroid Multi-Disciplinary Team (MDT) meeting involving head and neck surgery, radiology, pathology, nuclear medicine, and endocrinology to agree the surgical plan and post-operative management. The final operative plan is confirmed at the pre-operative consultation with the patient, covering the extent of surgery (hemithyroidectomy vs total thyroidectomy), whether neck dissection is required, the RLN and parathyroid risks, and the post-operative arrangements for calcium monitoring and thyroid hormone replacement.
Step 2 - Anaesthesia with EMG Endotracheal Tube
Under general anaesthesia with endotracheal intubation, a NIM EMG endotracheal tube is positioned with the surface electrodes lying against the vocal cords. The position is confirmed by the anaesthetist with direct laryngoscopy. The baseline RLN signal is recorded bilaterally before incision to confirm the monitoring system is working correctly. The patient is positioned with the neck extended (a shoulder roll beneath the shoulders) to expose the anterior neck.
Step 3 - Neck Incision and Thyroid Exposure
A Kocher incision (horizontal skin crease incision 1 to 2cm above the sternal notch) is made and deepened through the platysma. Subplatysmal flaps are elevated superiorly to the thyroid cartilage and inferiorly to the sternal notch. The strap muscles (sternohyoid and sternothyroid) are separated in the midline and reflected laterally to expose the thyroid lobes. The isthmus is divided if a hemithyroidectomy is being performed.
Step 4 - RLN Identification, Parathyroid Preservation, and Thyroid Lobe Mobilisation
The superior pole vessels are ligated individually close to the thyroid capsule (to protect the external branch of the superior laryngeal nerve - EBSLN). The inferior thyroid artery branches are ligated on the thyroid capsule (preserving the blood supply to the parathyroids). Both parathyroid glands on the operative side are identified. The RLN is identified in the tracheo-oesophageal groove, stimulated (confirmed on NIM monitor), and traced along its course to the larynx. The thyroid lobe is dissected off the trachea with the RLN under direct vision throughout, and the signal is re-confirmed after lobe removal. If total thyroidectomy: the contralateral side is treated identically.
Step 5 - Haemostasis and Wound Closure Meticulous haemostasis
This is achieved using the harmonic scalpel (ultrasonic energy haemostasis device that seals vessels up to 5mm with minimal thermal spread, reducing the risk of thermal damage to adjacent structures) and fine bipolar diathermy. The wound is closed in layers: strap muscles approximated in the midline, platysma closed with absorbable sutures, and skin closed with a subcuticular absorbable suture or skin glue for a cosmetically optimal scar. A small drain may be placed if there is concern about haematoma formation, typically removed at 24 hours.
Step 6 - Post-Operative Calcium Monitoring and Hormone Replacement Serum calcium and PTH
Are checked at 4 to 6 hours and the following morning after total thyroidectomy. Oral calcium carbonate (1g three times daily) and calcitriol (alfacalcidol) are started routinely and maintained until PTH recovery is confirmed. Levothyroxine is started on post-operative day 1 (dose adjusted to TSH level required for the cancer risk category). Patients are discharged with written instructions, calcium supplement prescriptions, and endocrine follow-up appointments at 4 to 6 weeks. Indirect laryngoscopy is arranged at 4 to 6 weeks post-operatively to confirm vocal cord function.
Patient Questions About Thyroid Surgery
Do I need to take medication for life after thyroid surgery?
After total thyroidectomy, the entire thyroid gland is removed, so the body can no longer produce thyroid hormone (T3 and T4). Lifelong levothyroxine (T4) replacement is required - a once-daily tablet that replaces the hormone the thyroid would have produced. The dose is adjusted based on TSH blood test results at follow-up. For patients with thyroid cancer, the dose is set to suppress TSH (keep it below normal) to reduce the stimulation of any residual thyroid cancer cells. For patients with benign disease, the dose is set to keep TSH in the normal range. After hemithyroidectomy (removal of one lobe), the remaining half of the thyroid gland may produce sufficient hormone without supplementation - approximately 70 to 80% of patients after hemithyroidectomy do not require levothyroxine, but this needs monitoring with regular TSH tests.
How serious is the risk of voice change after thyroid surgery?
Voice change after thyroid surgery can result from injury to the recurrent laryngeal nerve (RLN) (causing hoarseness from vocal cord palsy) or the external branch of the superior laryngeal nerve (EBSLN) (causing a change in voice pitch, particularly affecting singers or public speakers who use their upper vocal register). Temporary RLN palsy (neuropraxia from traction during dissection) occurs in 2 to 5% of thyroid operations and almost always recovers over weeks to months. Permanent RLN injury (from cutting or devascularising the nerve) occurs in less than 1% of thyroid operations in experienced hands with IONM. The risk is higher in re-operative thyroid surgery (completion thyroidectomy or re-do after previous operation) because scar tissue makes nerve identification more difficult, and in cancer surgery where the nerve is adherent to a large invasive tumour. If there is any change in voice after surgery, indirect laryngoscopy is arranged immediately.
What happens if a thyroid nodule turns out to be cancer after surgery?
If a thyroid nodule is found to be cancer on the final histology after hemithyroidectomy (where pre-operative FNAC was indeterminate and did not show cancer), the management depends on the cancer type and size. Small papillary microcarcinomas (under 1cm) confined to the removed lobe often do not require further surgery and can be managed with surveillance and TSH suppression. Larger papillary or follicular cancers, medullary cancers, or any cancer with high-risk features requires a completion thyroidectomy (removal of the remaining lobe) to allow radioactive iodine (RAI) ablation and complete surgical resection. This decision is made at the thyroid MDT after reviewing the histology report, and the patient is counselled before any further surgery is planned. At Shree Hospitals, all thyroid histology from operations where cancer is found is reviewed at the MDT within 2 weeks of surgery.
What is the difference between hemithyroidectomy and total thyroidectomy?
Hemithyroidectomy (also called thyroid lobectomy) removes one lobe of the thyroid gland (and the isthmus connecting the two lobes). It is used for benign nodules in one lobe, indeterminate nodules requiring diagnostic histology, or small papillary microcarcinomas confined to one lobe. The remaining lobe may continue to produce sufficient thyroid hormone without replacement in most patients. Total thyroidectomy removes the entire thyroid gland and is used for confirmed thyroid cancer, large bilateral multinodular goitre, Graves' disease, and cases where complete removal is required to allow radioactive iodine (RAI) therapy. After total thyroidectomy, lifelong levothyroxine replacement is mandatory. The choice between the two operations is driven by the diagnosis, the size and location of disease, the need for post-operative RAI, and the patient's individual risk and preference - discussed in detail at the pre-operative consultation.
Evidence-Based Case Studies by Our Specialists
Would Recommend Us
Patient with papillary thyroid cancer underwent total thyroidectomy, discharged on medication, and referred for radioactive iodine therapy after 6 weeks.
"When I was told I had thyroid cancer I was frightened. The surgical team at Shree Hospitals took me through every step clearly - the operation, the nerve monitoring, the follow-up with radioiodine. Everything went as planned and I have been cancer-free at my two-year review.
Mrs. Asha R.
Patient with Graves' disease and large goitre underwent total thyroidectomy, achieving symptom relief and stable thyroid function without complications.
"My thyroid was very large and the tablets were not controlling my symptoms well. The surgeon at Shree Hospitals explained the operation thoroughly and the team managed everything - from the pre-op medication to the calcium monitoring after the operation. I feel so much better and the scar is barely noticeable."
Mrs. Kavita M.
Patient with indeterminate thyroid nodule underwent hemithyroidectomy, confirmed benign follicular adenoma, recovered well, and required no levothyroxine therapy.
"The biopsy result was uncertain so the surgeon recommended removing the lobe to find out definitively. It turned out to be benign, which was a huge relief. My remaining thyroid is working fine and I do not need any medication. The team at Shree Hospitals managed everything professionally."
