Prospective comparison of health-related quality of life in patients undergoing open vs. transaxillary endoscopic thyroidectomy

Thyroid cancer is a disease that, while increasingly common, carries a remarkably high chance of survival. For the vast majority of patients, the primary treatment is surgery to remove the affected part of the gland. For decades, the standard approach has been a conventional open operation, where a surgeon makes a cut across the front of the neck to access the thyroid. This method is reliable and effective, but it leaves a visible scar that remains for the rest of a patient's life. In recent years, a different technique has emerged: endoscopic surgery. Instead of cutting the neck, the surgeon makes small incisions in the armpit and uses a camera and long instruments to reach the thyroid from below. This approach avoids any mark on the neck, offering a significant cosmetic advantage. However, because the surgery travels a longer path through the body, it is unclear whether this cosmetic benefit comes at the cost of a harder or slower recovery for the patient.

A team of researchers at Sichuan Cancer Hospital set out to settle this question by looking beyond the operating room and into the daily lives of patients. They wanted to know how these two different surgical paths affected a person's overall well-being, a concept known as health-related quality of life. This measure includes not just physical recovery, but also how a patient feels about their voice, their mood, their ability to concentrate, and their satisfaction with their appearance. The study focused specifically on papillary thyroid cancer, the most common and least aggressive form of the disease. By tracking hundreds of patients over the course of a year, the researchers aimed to determine which method allowed people to return to their normal lives with the fewest lingering problems.

The study followed 295 patients who underwent surgery between 2022 and 2023. The participants were divided into two groups based on their choice and medical suitability: one group received the traditional open surgery, while the other underwent the transaxillary endoscopic procedure, which enters through the armpit. Before the operations, and again at one, three, six, and twelve months afterward, the patients filled out detailed questionnaires. These surveys asked about specific issues such as pain, voice changes, numbness, anxiety, and the presence of scars. The researchers also tracked standard medical complications like temporary hoarseness or low calcium levels, ensuring that the comparison was fair and focused on the patient's personal experience.

The results revealed a clear trade-off between the two methods. Patients who had the open surgery recovered their physical functions slightly faster in the short term. They reported fewer issues with their throat and voice at the three-month mark and fewer muscle-related problems by the end of the year. However, this group carried a heavy burden of a different kind: the visible scar on their neck. Throughout the entire year of follow-up, patients in the open group consistently reported more problems related to their scar than those in the endoscopic group. The scar remained a source of concern, affecting their sense of well-being and body image long after the wound had physically healed. In contrast, the endoscopic group, while taking a bit longer to recover from the physical trauma of the surgery, did not have to deal with a neck scar. Their main challenges were different; they reported more headaches and a slower return of normal voice function, but they avoided the persistent cosmetic worry that plagued the other group.

Both groups shared a similar emotional journey. Before the surgery, patients in both groups experienced the highest levels of anxiety and depression. This fear is common when facing a cancer diagnosis and a major operation. Once the surgery was completed, these negative feelings began to fade for everyone. By the time the first year was over, the anxiety and depression that had weighed heavily on the patients before the operation had significantly improved, regardless of which surgical method they chose. This suggests that the act of treating the cancer itself provided a profound psychological relief that outweighed the specific differences in recovery speed.

The researchers concluded that while the open surgery offers a slightly quicker physical recovery, the endoscopic approach is the better choice for patients who prioritize avoiding a visible neck scar. For many people, the psychological relief of having no scar on their neck outweighs the extra time needed to recover from the surgery. The study highlights that the "best" surgery depends on what the patient values most. If a patient is willing to accept a longer recovery period to avoid a permanent mark on their neck, the endoscopic method provides a higher quality of life in the long run. The findings also underscore that the period before surgery is the most stressful for patients, suggesting that doctors should focus heavily on calming fears and managing anxiety before the operation begins. Ultimately, the choice between these two paths is not just a medical decision, but a personal one that balances the speed of healing against the desire for a scar-free appearance.
