BACKGROUND: Facial blushing is one of the most peculiar of human expressions. The pathophysiology is unclear, and the prevalence is unknown. Thoracoscopic sympathectomy may cure the symptom and is increasingly used in patients with isolated facial blushing. The evidence base for the optimal level of targeting the sympathetic chain is limited to retrospective case studies. We present a randomized clinical trial.
METHODS: 100 patients were randomized (web-based, single-blinded) to rib-oriented (R2 or R2-R3) sympathicotomy for isolated facial blushing at two university hospitals during a 6-year period. Quality of life (QOL) was investigated preoperatively and after 12 months by Short Form 36. Local effects and side effects were assessed by questionnaire.
RESULTS: The male/female ratio was 27/73. The median age was 29 years (range, 18-56 years. The response rate was 93%. QOL increased significantly in all social and mental domains in both groups. Overall, 85% of the patients had an excellent or satisfactory result, with no significant difference between the R2 procedure and the R2-R3 procedure. Mild recurrence of facial blushing occurred in 30% of patients within the first year. One patient experienced Horner's syndrome. Compensatory sweating occurred in 93% of patients, gustatory sweating 36%, and dry hands in 66%; 13% of patients regretted the operation despite thorough preoperative selection and information.
CONCLUSIONS: There were no significant differences in local effects or side effects between R2 and R2-R3 sympathicotomy for isolated facial blushing. Both were effective, and QOL increased significantly. Despite very frequent side effects, the vast majority of patients were satisfied. Surprisingly, many patients experienced mild recurrent symptoms within the first year; this should always be discussed with patients preoperatively.
