Abstract
Twenty-one patients with open wounds of the non-weight-bearing foot or the ankle underwent coverage with a free temporoparietal fascia flap and split-thickness skin graft. Our indications for this thin, well-vascularized flap included osteomyelitis and exposed tendon, bone, or fixation hardware. The pliability of the flap allowed superior restoration of natural anatomical contours. Only one flap was completely lost (95.2% overall success). There were four cases (20%) of partial flap loss, none of which required flap revision or a new flap. Four patients (19%) experienced transient donor-site alopecia, and one patient suffered transient palsy of the temporal branch of the facial nerve. One patient (4.7%) had an area of persistent scar alopecia in the temporal scalp after a donor-site hematoma that required revision under local anesthesia. Follow-up was available on 95% of the patients and averaged 20 months (range, 1-54 months). All patients resumed weight-bearing ambulation within 1 month from operation using unmodified footwear. The free TPF flap is a reliable coverage option, with long-term durability and minimal donor-site morbidity, for relatively superficial wounds of the distal lower extremity.
