Minimally Invasive Thyroidectomy: Combining Safety with Cosmetic Appeal

One liner: Scarless techniques of thyroidectomy (either with the robot or endoscope) are being adopted by surgeons to make the experience of this surgery cosmetically acceptable in younger patients while ensuring safety of critical structures adjacent to the thyroid.

Scarless thyroidectomy represents a significant advancement in the field of thyroid surgery, allowing patients to undergo thyroid removal without the traditional neck incision that typically leaves a visible scar. This innovative approach is gaining popularity due to its cosmetic benefits and reduced recovery times.

What is a scarless thyroidectomy?

Traditionally, thyroidectomy involves a horizontal incision in the neck, which can leave a scar measuring between four and eight cm. For many patients, especially women and young men who prioritize cosmetic outcomes, this scar can lead to self-consciousness and social stigma. In response to these concerns, surgeons have developed minimally invasive techniques that aim to eliminate or significantly reduce visible scarring

The most notable methods for performing scarless thyroidectomy include:

• Trans-Axillary Approach: This method allows surgeons to access the thyroid through the armpit using carbon dioxide insufflation (similar to laparoscopy). A working space is developed in the neck through which the thyroid gland is removed using specialized equipment.
• Transoral Endoscopic Thyroidectomy This technique involves accessing the thyroid gland through the mouth, utilizing small incisions in the mouth behind the lips 

Both of these surgeries can be performed by surgeons with robotic systems, allowing greater maneuverability and visualization, improving surgical outcomes while minimizing tissue damage. Robotic surgery has a lesser risk of conversion to open surgery as compared to traditional endoscopic techniques.

The advantages of opting for a scarless approach are compelling:

‍
    1. Aesthetic Appeal: The most significant benefit is the absence of a visible neck scar, which can enhance the patient's self-esteem and overall satisfaction with their appearance postsurgery.

‍
    2. Reduced Recovery Time: Patients often experience quicker recovery times with less postoperative pain compared to traditional open surgery. This leads to shorter hospital stays and faster returns to normal activities

‍
     3. Lower Complication Rates: Recent studies indicate that minimally invasive techniques have similar or even lower complication rates compared to conventional methods, including risk of recurrent laryngeal nerve injury ( which leads to hoarseness of voice) and hypoparathyroidism (which leads to lowered calcium levels)

Who can undergo a scarless thyroidectomy?

There are specific criteria for performing minimally invasive thyroidectomy. Thyroid gland size should be smaller than 6 cm in the case of benign lesions. Such a surgery can be done even in cancer patients, but ideally the tumour should be smaller than 2 cm. Experienced surgeons can operate on bigger tumors in selected cases at high-volume centers.
Patients with larger glands, bigger cancer size, spread to lymph nodes, or those who have received radiation therapy or undergone previous neck surgery are not suitable for this procedure.

Conclusion

Scarless thyroidectomy is revolutionizing how thyroid conditions are treated, offering patients not only medical benefits but also significant psychological advantages related to body image and self-perception. As surgical techniques continue to evolve, more patients may find themselves opting for these innovative approaches that prioritize both health and aesthetics. With ongoing advancements in technology and surgical methods, the future looks promising for those seeking effective treatment without compromising their appearance.
