Scarless Thyroidectomy

Thyroid surgery is undertaken for conditions ranging from benign nodules to confirmed malignancy. The traditional operation involves a small incision at the front of the neck. Although this incision generally heals well, it leaves a permanent mark.

Scarless thyroidectomy uses alternative access routes to reach the thyroid gland without making an incision on the visible part of the neck. Instead of making an incision across the front of the neck, access to the thyroid is obtained through alternative anatomical routes that avoid a visible cervical scar. Such procedures require advanced surgical expertise and a thorough understanding of endoscopic anatomical planes, and are considered only in appropriately selected patients. 

At Gleneagles Hospitals, candidacy for this approach is determined after a detailed evaluation that includes clinical examination, review of diagnostic imaging, and assessment of the characteristics and extent of the thyroid disease.

Scarless thyroidectomy involves removing the thyroid gland through access pathways that do not require a visible incision on the front of the neck. One technique used for this purpose approaches the thyroid through the oral cavity and is referred to as the transoral endoscopic vestibular approach (TOETVA). Access is gained by placing small incisions in the lower lip rather than on the front of the neck. A camera system and fine surgical instruments are introduced through these openings, allowing the surgeon to visualise the gland clearly while performing the procedure. A working corridor is then carefully created beneath the skin to adequately expose the thyroid gland, allowing the surgeon to proceed with controlled, precise dissection. The affected portion, or the entire gland when indicated, is then removed in line with established surgical principles.

Throughout the procedure, the recurrent laryngeal nerves are identified to protect vocal cord function. The parathyroid glands are also preserved to maintain calcium balance. In selected situations, other remote-access routes such as the transaxillary approach may be considered.

Irrespective of the access route used, the priority is thorough and safe excision of the affected thyroid tissue.

The primary reason for surgery is always the thyroid condition itself. The choice of access route is considered only after confirming that treatment standards will not be compromised.

Scarless thyroidectomy may be considered in patients with:

• Benign nodules that cause discomfort, pressure, or cosmetic concern

• Cytology reports that do not provide a clear diagnosis and require excision

• Early-stage, well-differentiated cancers confined to the thyroid gland

• A strong preference to avoid a visible neck scar

• A history of problematic scar formation

When the thyroid gland is significantly enlarged, when cancer extends beyond the gland, or when extensive lymph node removal is required, conventional open surgery is generally preferred.

Not every individual requiring thyroid surgery is suited to a remote-access technique. Suitability depends on gland size, disease extent, and anatomical considerations.

Patients more commonly considered appropriate include:

• Those with relatively small nodules

• Individuals with low-risk malignancy limited to the thyroid

• Patients without retrosternal extension

• Those without prior extensive neck operations

• Individuals who understand that cosmetic benefit does not replace surgical safety

Preoperative evaluation usually includes thyroid function tests and a detailed ultrasound examination. Fine needle aspiration cytology is performed where indicated. Additional imaging may be advised if there is concern about gland size or spread.

Scarless thyroidectomy may not be advisable in certain clinical situations, including:

• Large multinodular goitre

• Invasive or advanced thyroid cancer

• Significant cervical lymph node involvement

• Active oral infection in cases planned for transoral access

• Previous complex cervical surgery or radiation

In these circumstances, open thyroidectomy provides more direct exposure and may reduce operative risk.

At Gleneagles Hospitals, the operation is performed under general anaesthesia using endoscopic equipment in a fully equipped operating theatre.

Preoperative Preparation

Investigations are reviewed once again prior to surgery. Medications, particularly blood thinners, are assessed and adjusted if necessary. Patients are given fasting instructions and counselled regarding the nature of the operation, possible complications, and expected recovery.

Operative Technique

For the transoral method, small incisions are made inside the lower lip. A subcutaneous working plane is developed to reach the thyroid gland.

Dissection proceeds carefully, with identification of the recurrent laryngeal nerve along its anatomical pathway. Preservation of the parathyroid glands is prioritised. Where appropriate, nerve monitoring may assist in confirming nerve integrity during surgery.

After removal, the thyroid tissue is extracted through the same internal access site. The incisions are closed using absorbable sutures.

The length of the operation varies according to the extent of resection. Removal of one lobe generally requires less time than total thyroidectomy. Most procedures are completed within a few hours.

Postoperative Care

After surgery, monitoring focuses on breathing comfort, voice quality, and calcium levels when required.

Patients may notice:

• Mild swelling beneath the chin or neck

• Temporary numbness of the lower lip

• Throat irritation related to anaesthesia

• Localised discomfort

These effects usually settle within several days. Discharge is often possible within one to two days, depending on recovery and the extent.

Total thyroidectomy requires long-term thyroid hormone replacement. Histopathology findings are reviewed at follow-up, and additional treatment is advised if indicated.

The complications observed with this approach are generally in line with those recognised in standard thyroid operations and may include:

• Injury to the recurrent laryngeal nerve, which can affect vocal cord movement

• Temporary or persistent decrease in parathyroid activity resulting in low calcium levels

• Bleeding following surgery

• Infection at the surgical site

• Fluid accumulation in the operated region

• Altered sensation over the chin area in transoral procedures

The frequency of these complications depends on the extent of surgery and individual patient characteristics. At Gleneagles Hospitals, the choice of technique is made after balancing surgical safety, disease profile, and long-term management considerations.

In selected cases, scarless thyroidectomy offers the benefit of avoiding a visible neck incision while adhering to established principles of thyroid surgery. Endoscopic magnification allows the surgeon to view anatomical structures in greater detail during tissue dissection.

The technique is recommended only when it achieves the same clinical objectives as open surgery.

Scarless thyroidectomy is offered at Gleneagles Hospitals as part of its endocrine surgical services.

Available facilities include:

• Surgeons trained in advanced thyroid and endoscopic procedures

• Modern endoscopic systems

• Intraoperative nerve monitoring

• Dedicated anaesthesia and perioperative teams

• On-site pathology and laboratory support

• Structured postoperative follow-up and review

Each patient’s management plan is individualised according to diagnosis and operative considerations.

Although no incision is made on the front of the neck, the operation is carried out according to established principles of thyroid surgery and cancer management.

At Gleneagles Hospitals, the operative approach is chosen based on the characteristics of the thyroid condition and established safety parameters, with aesthetic considerations taken into account only when they do not interfere with effective treatment.
