Resurfacing of Face and Neck Using Superthin Thoracodorsal Artery Perforator Free Flaps

Abstract

Background: Resurfacing of facial and neck defects is challenging due to the unique skin color, texture, and thickness of the region. With the development of microsurgical reconstruction, perforator- free flaps can provide adequate soft tissue. However, despite various modifications, such flaps hardly satisfy cosmetic requirements, due to differences in color and bulkiness. We have used superthin thoracodorsal artery perforator (TDAp) free flaps to overcome these limitations. Methods: Between January 2012 and January 2020, 15 patients underwent reconstructive procedures for facial and neck soft tissue defects using superthin TDAp free flaps. First a perforator was found above the deep fascia and a flap was elevated over the superficial fascia layer. A process named "pushing with pressure and cutting" was carried out before pedicle ligation until all the superficial fat tissue had been removed except for around the perforator. Patient satisfaction was evaluated using a questionnaire about color, contour, and overall satisfaction a minimum of 12 months after surgery. Results: Flap size ranged from 6 x 4 cm to 25 x 14 cm (mean, 126.3 cm(2)). Final flap thickness ranged from 4 to 6 mm. (mean, 4.97 mm). All flaps survived without any loss and there were no flap-related complications. After a mean follow-up period of 14.4 months, patients were satisfied with the aesthetic results, and cervical range of motion increased by 11.25 degree on average in burn scar contracture patients. Conclusions: The superthin TDAp free flap is an excellent alternative to face and neck resurfacing, providing a large and thin flap with excellent color matching and good vascularity.
