Long-term donor site morbidity after radial forearm flap elevation for tongue reconstruction: Prospective observational study

Background To assess long-term donor site morbidity after radial forearm free (RFF) flap harvesting. Methods Enrolled patients were asked to complete the Disability of the Arm, Shoulder, and Hand (DASH) questionnaire and undergo wrist motion and hand strength examinations at different time points. The data were prospectively collected and retrospectively analyzed. Results The postoperative DASH score did not return to normal until 24 months after the operation. The mean postoperative wrist motion degree of flexion was significantly decreased compared to the preoperative level and returned to normal at 12 months after the operation. Similar trends were noted regarding extension, radial abduction, and ulnar abduction. The mean postoperative grip strength was significantly decreased compared to the preoperative level and remained dysfunctional at 24 months after the operation. A similar trend was also noted with regard to tip pinch and key pinch. Conclusion The long-term negative effect on hand strength is sustained.

Automated summary

The postoperative DASH score took 24 months to return to normal, while wrist motion degree of flexion returned to normal at 12 months. Grip strength remained dysfunctional at 24 months post operation, indicating sustained long-term negative effects on hand strength.
