Globus Symptoms in Patients Undergoing Thyroidectomy: Relationships with Psychogenic Factors, Thyroid Disease, and Surgical Procedure.

BACKGROUND
The number of patients who need thyroid surgery has increased worldwide in recent decades. Patients with thyroid disease experience globus pharyngeus as a result of direct compression and edema of the surrounding organs. Thyroid surgery is needed to improve these symptoms or as treatment for thyroid cancer. After thyroid surgery, globus symptoms may become worse and may affect the daily life of the patient for a long time. Psychogenic problems have also been thought to cause the globus sensation. A prospective analysis of globus symptoms and psychogenic factors following thyroidectomy was performed.


MATERIAL AND METHODS
Patients scheduled to undergo thyroid surgery between February and September 2016 completed the foreign-body sensation in the throat score (FBST; range 0-8.2) and the self-rating depression scale (SDS; range 0-100) preoperatively and three days, one month, three months, six months, and 12 months postoperatively.


RESULTS
Long-term follow-up was completed in 616 patients (491 females). A total of 365 patients had thyroid cancer, 169 had benign tumors, and 82 had diffuse goiters with Graves' disease. The percentage of patients who complained about neck discomfort (FBST >2) was 29.4% before surgery. A preoperative high FBST showed a significant direct correlation with a high SDS, but thyroid volume did not. A postoperative high FBST was seen in 75.3% of patients at two days and 78.9% at one month after surgery, and it then gradually decreased to 49.3% at 12 months after surgery. At three days after the operation, the median FBST was significantly higher in patients who had total thyroidectomy with lateral neck dissection or total thyroidectomy only compared to those who had lobectomy only (p < 0.05). These differences were still present 12 months after surgery. A higher preoperative SDS score was also identified as an independent predictor for a high FBST at 12 months after surgery, but not at one or three months postoperatively, on multivariate analyses.


CONCLUSION
Preoperative globus symptoms appear directly related to psychological factors. The area of the surgical procedure and preoperative psychological factors were related to persistent neck discomfort.
