Recipient Vessels for Free Tissue Flaps in Advanced Oncologic Defects of the Midface and Scalp

The goal of this clinical trial is to compare the postoperative outcomes based on superficial temporal versus cervical recipient vessels for midface and scalp advanced oncologic defects using free tissue flap for reconstruction. The main question it aims to answer is: • Which recipient vessel is most suitable for performing microanastomosis using free flaps for advanced midface and scalp oncologic defect. Participants will be undergo resection of advanced malignant tumors of the midface and scalp with subsequent oncological reconstruction using free tissue flap. Researchers will compare two groups where those in whom superficial temporal vessels will be used as the recipient vessels (group A) and those in whom cervical vessels will be used as the recipient vessels (group B) to see if there is a recipient vessel who is most suitable for performing microanastomosis using free flaps for advanced midface and scalp oncologic defect.
