Repair of Defects in the Scalp and Face With Expanded Superficial Temporal Artery Flaps: A Single-Center Retrospective Study.

BACKGROUND AND

OBJECTIVE

Defects resulted from the removal of large scars, benign tumors, severe pigmentation abnormalities, and vascular malformations, etc., in the scalp and face need to be repaired to restore the appearance. Here, the authors introduced the application of various expanded superficial temporal artery (STA) flaps in the repair of above defects.

METHODS

From Jan. 2015 to Dec. 2018, 19 patients with craniofacial secondary defects received the repair with expanded STA flaps in our clinic. The defects were resulted from the removal of scalp scar (n = 6), neurofibroma (n = 4), sebaceous nevus (n = 3), arteriovenous malformation (n = 2), facial scar (n = 2), and port-wine stain (n = 2). The expanded STA flaps included 14 cases of flaps pedicled by parietal branch of STA, 2 cases of flaps pedicled by parietal branch of STA combined with laser hair removal, 1 case of flaps pedicled by frontal branch of STA, and 2 cases of prefabricated expanded skin flap with the superficial temporal fascia in the neck.

RESULTS

The two-stage operation and water-filling expansion were accomplished in all patients. All flaps survived well, except one flap with venous congestion, which resolved after blood-letting and application of drugs promoting venous draining. In the three to six months follow-up, the flaps' color, texture, and thickness were satisfying.

CONCLUSIONS

Individual application of different types of expanded STA flaps could achieve ideal results in repairing craniofacial secondary defects.
