Versatility of subscapular chimeric free flaps in the secondary reconstruction of composite posttraumatic defects of the upper face.

ABSTRACT: High energy injuries to the upper face present challenging reconstructive problems. In some cases, initial reconstructive efforts result in unfavorable outcomes that require secondary intervention. Chimeric free flaps based on the subscapular system offer the tissue components and volume needed for these complex reconstructions. This is a series of five patients who underwent secondary reconstruction of the middle and upper face following traumatic injury. Mechanism of injury, prior attempts at reconstruction, and characteristics of the tissue defects and the flaps used in their reconstruction are described. Two patients were female and three were male. Three injuries resulted from gunshot wounds, and two from motor vehicle accidents. All patients had multiple prior failed attempts at reconstruction using local/regional tissue. Defects included symptomatic oronasal or oro-orbital fistulas, enophthalmos, and forehead contour deformities. Two of the flaps used included scapular bone and latissimus muscular components, and three included scapular bone and thoracodorsal artery perforator-based skin paddle components. All free tissue transfers were successful, and no patients suffered significant complications. Chimeric free flaps based on the subscapular system offer a valuable secondary strategy for reconstruction of composite defects of the upper face when other options have been exhausted through previous efforts.

Reconstruction of Upper Extremity Defects by Random Pedicle Abdominal Flaps: Is It Still a Valid Option?

Project description:Traumatic soft tissue defects of the hand and upper extremities are common and may be challenging to the reconstructive surgeon. Several reconstructive procedures such as use of local, regional, distant, and free flaps have been described. This study aimed to report the techniques, outcomes, and complications of pedicle abdominal flaps in reconstructing hand and upper extremity defects.MethodsIn this retrospective study, we included patients with different traumatic defects in the hand and upper extremities who underwent reconstruction by random pedicle abdominal flaps between 2002 and 2017 at Jordan University Hospital, Jordan. Data were collected and analyzed, and the variables studied included patient age and sex, etiology and size of the defect, complications, outcomes, and the need for further revision procedures. Appropriate statistical analysis was used to examine the potential factors affecting flap survival.ResultsWe included a total of 34 patients with a mean age of 22.2 years, ranging from 1 to 54 years. Finger degloving was seen in approximately half of the patients. Flap survival rate was 85.3%. A small area of defect was the only risk factor that significantly affected the flap failure rate.ConclusionsThin pedicle abdominal flaps are a valid, affordable, and safe option in upper extremity traumatic defects, especially in situations where microsurgical techniques are unavailable or contraindicated. Extra care should be taken when the defect surface area is small.

Reconstruction of post-traumatic upper extremity soft tissue defects with pedicled flaps: An algorithmic approach to clinical decision making.

Project description:PurposePedicled flaps are still the workhorse flaps for reconstruction of upper limb soft tissue defects in many centers across the world. They are lifeboat options for coverage in vessel deplete wounds. In spite of their popularity existing algorithms are limited to a particular region of upper limb; a general algorithm involving entire upper limb which helps in clinical decision making is lacking. We attempt to propose one for the day to day clinical practice.MethodsA retrospective analysis of patients who underwent pedicled flaps for coverage of post-traumatic upper extremity (arm, elbow, forearm, wrist & hand) soft tissue defects within the period of January 2016 to October 2017 was performed. Patients were divided into groups according to the anatomical location of the defects. The flaps performed for different anatomical regions were enlisted. Demographic data and complications were recorded. An algorithm was proposed based on our experience, with a particular emphasis made to approach to clinical decision making.ResultsTwo hundred and twelve patients were included in the study. Mean age was 27.3 years (range: 1-80 years), 180 were male, and 32 were female. Overall flap success rate was 98%, the following complications were noted marginal flap necrosis requiring no additional procedure other than local wound care in 32 patients (15%), partial flap necrosis requiring flap advancement or extra flap in 15 patients (7%), surgical site infection in 11 patients (5%), flap dehiscence requiring re-suturing in 5 patients (2.4%), total flap necrosis 4 patients (2%).ConclusionThe proposed algorithm allows a reliable and consistent method for addressing diverse soft tissue defects in the upper limb with high success rate.

Reconstruction of a Large Composite Hemicraniofacial Defect with Bipedicled DIEP/TRAM Flaps.

Project description:Head and neck reconstructions are often challenging due to the mix of functional and aesthetic goals. It can be tricky when different tissue types are required to reconstruct each subunit. Craniofacial reconstructions require a large volume of tissue to cover defects that span across a large convex area. The latissimus dorsi muscle flap is a workhorse free flap used frequently by surgeons due to its ability to cover over a large surface area. However, there are unique situations when even the latissimus dorsi muscle is not enough to provide the bulk cover for the craniofacial defect. We present a complex case of a hemicraniofacial reconstruction after a hemifacial orbital exenteration and cranial resection of a large neglected basal cell carcinoma.

Tunneled Island Flaps for the Reconstruction of Nasal Defects: A 21-Case Series.

Project description:(1) Background: The reconstruction of cutaneous defects following surgical procedures in the nasal pyramid presents a challenge due to the limited amount of available tissue. In cases of larger defects, skin from adjacent units is used. Traditionally, two-stage surgical flaps have been employed for reconstructing these defects. Tunnelized island flaps allow for the one-stage surgical reconstruction of nasal pyramid defects, using tissue from the forehead or cheek for the flap. (2) Methods: Descriptive retrospective study of 21 consecutive patients who underwent surgery for defects on the nasal pyramid using tunnelized island flaps. (3) Results: Surgical reconstruction was performed in 21 patients with basal cell carcinomas, 14 of them using the melolabial island flap and 7 using the paramedian forehead island flap. In all cases except one, clear histological margins were obtained. Immediate complications were mild and minor. It is worth noting the trapdoor effect complication, which improved over time in most cases, resulting in a satisfactory cosmetic outcome. No tumor recurrences were observed during an average follow-up period of 17.7 months. (4) Conclusions: Tunnelized island flaps allow for single-stage reconstruction of nasal pyramid defects, yielding excellent cosmetic results by utilizing adjacent skin. This procedure demands a certain level of skill but is associated with minimal complications, making it a valuable alternative in reconstructive dermatological surgery.

The Use of Local Perforator Flaps in Delayed or Secondary Breast Reconstruction.

Project description:Local perforator flaps are used as immediate volume replacement techniques in breast conserving surgery. Here, we describe a case series of local perforator flaps used in the delayed setting to correct defects following previous breast surgery, including previous breast conservation surgery or mastectomy with reconstruction. All cases were performed in a tertiary referral breast unit between 2014 and 2020. Cases were identified using a prospectively maintained database. Indications, type of perforator flap used, immediate post-operative complications, and longer term outcomes were recorded. Fifteen cases were identified: 8 following previous breast conserving surgery and radiotherapy, 6 following mastectomy and reconstruction, and 1 for developmental breast asymmetry following childhood radiotherapy. Indications included volume deficit, contour defect, asymmetry, and capsular contracture. One patient a major complication requiring return to theater due to implant-related infection. There were no flap losses. Longer term, 2 patients underwent lipomodeling to further augment breast volume as part of a planned, staged revision. One patient subsequently elected to have bilateral breast implant exchange to increase volume. Our series shows the versatility of local perforator flaps in the correction of complex breast defects that can occur following previous breast surgery. Delayed local perforator flaps are associated with low morbidity, and further revision surgery is not commonly required.

Layered Closure of Lumbosacral Myelomeningocele Defects with Bilateral Paraspinous Muscle and Composite Fasciocutaneous Flaps.

Project description:Robust, reliable, and reproducible closure of lumbosacral myelomeningocele defects remains a challenge. In infants with lumbosacral myelomeningocele defects, multiple methods of soft tissue coverage have been described. These include various cutaneous, fascial, and muscle flaps and grafts. This is done with relative ease when ample soft tissue is present but becomes extremely difficult for large and distally located defects. We present here our closure technique of lumbosacral myelomeningocele defects in newborns, with associated short- and medium-term outcomes. We demonstrate the anatomy of this technique with fresh cadaver dissection and present a review of demographic and outcome data of 12 consecutive patients treated with this method from June 2014 to August 2019. No major intra- or postoperative complications have been encountered, with a mean follow-up of 22.2 months and median follow up of 18 months. After the neurosurgical repair of lumbosacral myelomeningocele, bilateral composite fascial flaps composed of thoracolumbar and gluteus maximus fascia are elevated in continuity. The paraspinous muscle flaps are then elevated, disinserted distally, and medialized to provide complete muscular coverage of the dural repair. The bilateral composite fascial flaps are medialized and closed over the deep paraspinous muscle flap repair. Two patients experienced areas of small, superficial skin necrosis, one of which healed by secondary intention and the other by debridement and full-thickness skin grafting. Use of bilateral paraspinous muscle flaps and bilateral composite fascial flaps composed of thoracolumbar and gluteus maximus fascia provides robust coverage of lumbosacral defects following myelomeningocele repair in infants.

Pedicled sural flaps versus free anterolateral thigh flaps in reconstruction of dorsal foot and ankle defects in children: a systematic review.

Project description:BackgroundThis systematic review compared free anterolateral thigh (ALT) flaps versus pedicled distally based sural artery (DBSA) flaps for reconstruction of soft tissue defects of dorsal foot and ankle in children.MethodsA systematic literature search was performed to identify cases where an ALT or DBSA was used to reconstruct the dorsal foot in children. A total of 19 articles were included in the systematic review.ResultsEighty-three patients underwent an ALT reconstruction and 138 patients underwent a DBSA reconstruction. Patients who had a DBSA were more likely to require grafting of the donor site (P<0.001). The size of ALT flaps was significantly larger than DBSA flaps (P=0.002). Subsequent flap thinning was required in 30% of patients after ALT and 12% of patients after DBSA reconstruction (P<0.001). Complications occurred in 11.6% of DBSA and 8.4% of ALT flaps (8.4%).ConclusionsBoth flaps are valid options in reconstructing pediatric foot and ankle defects. Each flap has advantages and disadvantages as discussed in this review article. In general for larger defects, an ALT flap was used. Flap choice should be based on the size of the defect.

Neo-digit functional reconstruction of mutilating hand injury using transplantation of multiple composite tissue flaps.

Project description:PurposeFunctional reconstruction of mutilating hand injuries poses a challenge to the surgeon. We present our experience with use of multiple composite tissue flaps transplant for functional reconstruction of hand in patients with mutilating hand injuries. The associated merits and demerits of these surgical approaches are briefly discussed.MethodsFrom August 2004 to October 2014, functional reconstruction of hand with transplantation of multiple composite tissue flaps was performed in 8 patients. These included the toe with dorsal pedis artery flap, the reverse posterior interosseous artery flap, and the anterolateral thigh flap. Mean interval from injury to functional reconstruction was 10.6 days.ResultsAll transplanted skin flaps and reconstructed neofingers survived completely. Only 1 patient developed wound infection at the recipient site (hand), which resolved without any debridement or revision surgery. At the donor site (foot), partial skin necrosis was observed in 1 patient, which healed with local wound care. In other patients, all wounds healed without any complications. The average range of movement at the neofinger metacarpophalangeal and interphalangeal joints was 38° and 73°, respectively. None of the patients required revision surgery.ConclusionUse of negative pressure wound therapy and multiple composite tissue flap transplantation appears to be an effective strategy for hand functional reconstruction in patients with mutilating hand injuries. Among the multiple composite tissue flaps, use of toe transplantation combined with reverse posterior interosseous artery flap appears to be the best option.

Reconstruction of Upper Eyelid Defects Secondary to Malignant Tumors with a Newly Modified Cutler-Beard Technique with Tarsoconjunctival Graft.

Project description:PurposeWe describe a modification of Cutler-Beard's technique, using a contralateral tarsoconjunctival graft, in patients who underwent excision of large malignant tumors of the upper eyelid.MethodsThis is an interventional retrospective review (clinical study) of ten cases, with age range from 64 to 86 years (mean: 71.2 years ± 6.49) with malignant upper eyelid tumors, operated by the same surgeon (AB-G), between 2011 and 2016. The resulting defects were reconstructed using a modification of Cutler-Beard's technique. A tarsoconjunctival graft was harvested from the contralateral upper eyelid, with an extra 3 mm of conjunctiva from the superior edge of tarsus and was attached to the upper eyelid defect, different from that previously described. Follow-up ranged between 24 and 60 months (mean: 41.6 ± 9.87). Functional, cosmetic outcomes and postoperative complications were evaluated.ResultsNo upper eyelid retraction, eyelid margin entropion, or graft retraction was observed in any of the cases. All of the patients were satisfied with the aesthetic result.ConclusionThis technique allows us to safely inset a suitable graft on the ocular surface, with sufficient blood supply, resulting in a stable margin and good contour.

Versatility of adipofascial anterolateral thigh flap for reconstruction of maxillary defects with infratemporal fossa extension.

Project description:Tumors arising from the posterior hard palate or posterolateral maxilla may extend to involve the infratemporal fossa (ITF). Resection of these tumors results in infrastructural maxillectomy with ITF defects. In this study, we describe the use of an adipofascial anterolateral thigh flap (ALT) specifically for such defects. This case series includes four patients who underwent an infrastructure maxillectomy with ITF clearance and the resultant defects were reconstructed using adipofascial anterolateral thigh flaps. The complications as well as the functional outcomes were assessed. This study included patients with lesions involving the hard palate, posterolateral part of maxilla with extension into the ITF. The mean flap dimension was 150 cm(2) (range, 120-180 cm(2)). All flaps were harvested based on a single perforator. The flap was used to obliterate the ITF defect and also to achieve oroantral separation. All flaps mucosalized well within 6 weeks. All patients were on oral diet and had adequate mouth opening. There were no donor-site complications. Adipofascial ALT is an excellent choice for infrastructural maxillectomy defects with ITF extension. The intraoral part got mucosalized well and provided a smooth and taut surface. A large adipofascial tissue flap helps obliterate the ITF, thus minimizing complications.
