Mid-term Clinical Outcome of Microvascular Gracilis Muscle Flaps for Defects of the Hand

PURPOSE

Gracilis muscle flaps are useful to cover defects of the hand. However, there are currently no studies describing outcome measurements after covering soft tissue defects using free flaps in the hand.

AIM

To analyze mid-term results of gracilis muscle flap coverage for defects on the hand, with regard to functional and esthetic integrity.

METHODS

16 patients aged 44.3 (range 20-70) years were re-examined after a mean follow-up of 23.6 (range 2-77) months. Mean defect size was 124 (range 52-300) cm2 located palmar (n = 9), dorsal (n = 6), or radial (n = 1). All flaps were performed as microvascular muscle flaps, covered by split thickness skin graft.

RESULTS

Flaps survived in 15 patients. 6 patients required reoperations. Reasons for revisions were venous anastomosis failure with total flap loss (n = 1) requiring a second gracilis muscle flap; necrosis at the tip of the flap (n = 1) with renewed split thickness skin cover. A surplus of the flap (n = 2) required flap thinning and scar corrections were performed in 2 patients. Mean grip strength was 25% (range 33.3-96.4%) compared to the contralateral side and mean patient-reported satisfaction 1.4 (range 1-3) (1 = excellent; 4 = poor).

CONCLUSIONS

Gracilis muscle flaps showed a survival rate of 94%. Patients showed good clinical outcomes with acceptable wrist movements and grip strength as well as high reported satisfaction rates. Compared to fasciocutaneous free flaps, pliability and thinness especially on the palmar aspect of the hand are advantageous. Hence, covering large defects of the hand with a gracilis muscle flap can be a very satisfactory procedure.

Expanding the Armamentarium of Donor Sites in Microvascular Head and Neck Reconstruction

The field of microsurgical head and neck reconstruction has witnessed tremendous advancements in recent years. While the historic goals of reconstruction were simply to maximize flap survival, optimizing both aesthetic and functional outcomes has now become the priority. With an increased understanding of perforator anatomy, improved technology in instruments and microscopes, and high flap success rates, the reconstructive microsurgeon can push the envelope in harvesting and designing the ideal flap to aid patients following tumor extirpation. Furthermore, with improvements in cancer treatment leading to improved patient survival and prognosis, it becomes increasingly important to have a broader repertoire of donor sites. The present review aims to provide a review of newly emerging soft tissue flap options in head and neck reconstruction. While certainly a number of bony flap options also exist, the present review will focus on soft tissue flaps that can be harvested reliably from a variety of alternate donor sites. From the upper extremity, the ulnar forearm as well as the lateral arm, and from the lower extremity, the profunda artery perforator, medial sural artery perforator, and superficial circumflex iliac perforator flaps will be discussed, and we will provide details to aid reconstructive microsurgeons in incorporating these alternative flaps into their armamentarium.

Osteocutaneous superficial circumflex iliac perforator flap for the lower extremity bone and soft tissue reconstruction with perforator-to-perforator anastomosis after radical debridement of tibia osteomyelitis: A case report

Reconstruction of soft tissue and bone defects in tibia chronic osteomyelitis is challenging and often managed by free flap with bone graft. However, the use of osteocutaneous free flap combined with perforator-to-perforator anastomosis has not been reported. We report the case of a 62-year-old man presenting with soft tissue and bone defects with right tibial chronic osteomyelitis, which was successfully treated with an osteocutaneous superficial circumflex iliac perforator (SCIP) flap with perforator-to-perforator anastomosis. After radical debridement and excision of the sequestrum, a 17 × 10-cm skin defect and a 4 × 3-cm bone defect remained. An osteocutaneous SCIP flap, containing a 16 × 9-cm skin paddle and 4 × 2-cm iliac bone, was transferred and anastomosed to the posterior tibial perforator in an end-to-end fashion. An artificial dermis was placed to cover the soft tissue. At 1 week postoperatively, the artificial dermis was partially infected, which required small debridement. Full weight-bearing was permitted 5 weeks postoperatively, and the patient walked independently. No evidence of recurrence of osteomyelitis or skin ulcers was observed at 15 months postoperatively. Therefore, osteocutaneous SCIP flap with perforator-to-perforator anastomosis may be a potential alternative treatment for soft tissue and bone defects after radical debridement of tibia osteomyelitis.
