Investigate the improvement of facial skin texture with the VISIA system after total thyroidectomy.

BACKGROUND

During clinical practice we have noticed that some patients with hyperthyroidism have finer skin with less wrinkles, pores, and spots after thyroidectomy, and the improvement can be observed within a few weeks after the operation. However, there is no evidence or study in the literature to proof this finding.

AIM AND OBJECTIVE

This study was designed to evaluate and quantify the skin characters of patients with hyperthyroidism before and after thyroidectomy.

MATERIAL AND METHODS

This is a prospective study to include patients with hyperthyroidism who received total thyroidectomy between March 1st, 2018 and February 28th, 2019. The patients received blood test for T4 and TSH analysis and VISIA measurements for skin texture quantification, at the preoperative stage, three, and six months postoperatively. A total of 8 patients were included. Repeated measurement was used to determine the lab data and VISIA measurement changes before and after the operation. Mauchly's sphericity test was performed to determine whether the violation of sphericity occurs, and the Greenhouse-Geisser correction was used when the violation of sphericity occurs.

RESULTS

All the patients were female and generally healthy without systemic medical disease except the hyperthyroidism. The T4 and TSH levels were not significantly different before and after the thyroidectomy. In terms of the skin character measurements, the wrinkles, texture, pores, UV spots, and brown spots were not improved after thyroidectomy. A trend of improvement in spots, red area, and porphyrin was noted, although not statistically significant.

CONCLUSIONS

Surgical removal of the thyroid gland in patients with hyperthyroidism does not improve the skin quality and texture in examinations via the VISIA system.
