The instep flap and medialis pedis flap are both originate based on the medial plantar artery. The medialis pedis flap is based from the deep branch and the instep flap is based from the superficial branch. To increase the axial rotation, it is acceptable to ligate the lateral plantar artery. However, this can partially affect the blood supply of the plantar metatarsal arch. We restored the blood flow with a vein graft between the posterior tibial artery and the ligated stump. From 2012 to 2020, 12 cases of heel reconstruction, including seven instep flaps and five medialis pedis flaps, were performed with ligation of the lateral plantar artery. The stump of the lateral plantar artery was restored with a vein graft and between the posterior tibial artery and the ligated stump. Patients were followed for 18 months. Long-term results showed the vascular restoration of the lateral plantar artery remained patent demonstrated by doppler ultrasonography. Restoring blood flow to the lateral plantar artery maintains good blood supply to the toes. If the patient in the future develops a chronic degenerative disease, with microvascular complications, bypass surgery can still be performed because of the patency of both branches.
Purpose: Reconstruction of soft tissue defects of the foot often requires free-flap transfer. Free muscle flap transfer and skin grafts on the muscle has been an option for these defects. Here we present our experiences of foot reconstruction using an endoscopy-assisted free muscle flap harvest. Methods: Using endoscopy-assisted free muscle flap harvests, four patients with soft tissue defects of the foot were treated with a free muscle flap and skin graft. The gracilis muscle was used for two patients and the rectus abdominis muscle for two. A single small transverse skin incision was placed on the lower abdomen for the rectus abdominis muscle. A small transverse skin incision on the proximal thigh was the only incision for harvesting the gracilis muscle flap. The small incisions were enough for the muscle flap to be pulled through. Results: The flaps survived successfully in all cases. Contours were good from both functional and aesthetic aspects. No breakdowns or ulcerations of the flap developed during long-term follow-up. Resultant scars were short and relatively hidden. Functional morbidities such as abdominal bulging were not noted. Conclusion: Endoscopy-assisted harvest of muscle flap and transfer with skin graft is a good option for soft tissue defects of the foot. Morbidities of the donor site can be minimized with endoscopic flap harvest. This method is preferable for young patients who want a small donor site scar.
The nose is the most prominent area of the face, therefore susceptible to trauma and skin cancer. When small sized defect is in nasal tip, it results in disturbance of the facial harmony even if replantation, composite graft, skin graft or median forehead flap has been used for the reconstruction. So it is needed that the best method reconstruction is performed according to the degree of defect or deformity. And at the same time the physiology and anatomy of nose were clarified and its aesthetic subunits were employed. How can we cover the about 3 cm sized nasal defect in nasal tip with cartilage exposure? At first, we can think forehead island flap is most appropriate. We performed 7 cases of the forehead island flap for reconstruction of the defect in nasal tip(4 cases: cancer, 3 cases: trauma) from March, 2001 to August, 2004. This result was satisfactory in the point of texture, color, donor scar, and there were no complication such as wound disruption, infection, flap atrophy, and hematoma. The advantages of forehead island flap are: 1) No injury of deep vessel and nerve, 2) control of shape and volume, 3) Short operation time, 4) primary closure of donor site, 5) one stage operation. Also, forehead island flap can cover the defect in nose where skin graft and local flap can not cover. But, operator always must take care for flap congestion and donor site scar. We thought forehead island flap is one of the best option of reconstruction of nasal tip defect.

Background Robots have allowed head and neck surgeons to extirpate oropharyngeal tumors safely without the need for lip-split incision or mandibulotomy. Using robots in oropharyngeal reconstruction is new but essential for oropharyngeal defects that result from robotic tumor excision. We report our experience with robotic free-flap reconstruction of head and neck defects to exemplify the necessity for robotic reconstruction. Methods We investigated head and neck cancer patients who underwent ablation surgery and free-flap reconstruction by robot. Between July 1, 2011 and March 31, 2012, 5 cases were performed and patient demographics, location of tumor, pathologic stage, reconstruction methods, flap size, recipient vessel, necessary pedicle length, and operation time were investigated. Results Among five free-flap reconstructions, four were radial forearm free flaps and one was an anterolateral thigh free-flap. Four flaps used the superior thyroid artery and one flap used a facial artery as the recipient vessel. The average pedicle length was 8.8 cm. Flap insetting and microanastomosis were achieved using a specially manufactured robotic instrument. The total operation time was 1,041.0 minutes (range, 814 to 1,132 minutes), and complications including flap necrosis, hematoma, and wound dehiscence did not occur. Conclusions This study demonstrates the clinically applicable use of robots in oropharyngeal reconstruction, especially using a free flap. A robot can assist the operator in insetting the flap at a deep portion of the oropharynx without the need to perform a traditional mandibulotomy. Robot-assisted reconstruction may substitute for existing surgical methods and is accepted as the most up-to-date method.

Background Slim patients or those with large breasts may be ineligible for breast reconstruction with an abdominal flap, as the volume of the flap may be insufficient. This study aimed to establish that abdominal tissue-based breast reconstruction can be well suited for Korean patients, despite their thin body habitus. Methods A total of 252 patients who underwent postmastectomy breast reconstruction with an abdominal flap from October 2006 to May 2013 were retrospectively reviewed. The patients' age and body mass index were analyzed, and a correlation analysis was performed between the weight of the mastectomy specimen and that of the initial abdominal flap. Results The average weights of the mastectomy specimen and initial abdominal flap were 451.03 g and 644.95 g, respectively. The ratio of the weight of the mastectomy specimen to that of the initial flap was $0.71{\pm}0.23$. There was a strong positive linear relationship between the weight of the mastectomy specimen and that of the initial flap (Pearson correlation coefficient, 0.728). Thirty nulliparous patients had a final-to-initial flap weight ratio of $0.66{\pm}0.11$. The 25 patients who underwent a contralateral procedure had a ratio of $0.96{\pm}0.30$. The adjusted ratio of the final flap weight to the initial flap weight was $0.66{\pm}0.12$. Conclusions Breast weight had a strong positive relationship with abdominal flap weight in Koreans. Abdominal flaps provided sufficient soft tissue for breast reconstruction in most Korean patients, including nulliparous patients. However, when the mastectomy weight is estimated to be >700 g, a contralateral reduction procedure may be considered.

The medial sural artery perforator (MSAP) flap is a versatile fasciocutaneous flap, and yet is less commonly utilized than other free flaps in microvascular reconstructions of the head and neck. The aim is to conduct a high-quality Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA)- and Assessment of Multiple Systematic Reviews 2 (AMSTAR 2)-compliant systematic review comparing the use of the MSAP flap to other microvascular free flaps in the head and neck. Medline, Embase, and Web of Science databases were searched to identify all original comparative studies comparing patients undergoing head and neck reconstruction with an MSAP flap to the radial forearm free flap (RFFF) or anterolateral thigh (ALT) flap from inception to February 2021. Outcome studied were the recipient-site and donor-site morbidities as well as speech and swallow function. A total of 473 articles were identified from title and abstract review. Four studies met the inclusion criteria. Compared with the RFFF and the ALT flaps, the MSAP flap had more recipient-site complications (6.0 vs 10.4%) but less donor-site complications (20.2 vs 7.8%). The MSAP flap demonstrated better overall donor-site appearance and function than the RFFF and ALT flaps (p = 0.0006) but no statistical difference in speech and swallowing function following reconstruction (p = 0.28). Although higher quality studies reviewing the use of the MSAP flap to other free flaps are needed, the MSAP flap provides a viable and effective reconstructive option and should be strongly considered for reconstruction of head and neck defects.
From January 1980 to May 1995, ninety-six patients had been treated by free-flap transfer for the soft tissue defects of the extremities. Ninety-eight cases of free-tissue transfer were reviewed to evaluate the clinical reliability in terms of survival and quality of long-time function after reconstructive surgery. Among these 98 cases(27 cases in latissimus dorsi myocutaneous flap, 25 in dorsalis pedis flap, 20 in forearm fasciocutaneous flap, 9 in groin flap, 7 in gracilis myocutaneous flap, 6 in 1st web space flap of foot and 4 cases in tensor fascia lata flap), 92 cases of then were survived. 7 cases were performed with vein grafts. We ananalyzed the reconstruction of the extremities on 98 cases with the soft tissue defects which had been reconstructed free-flap transfer and followed for minimum 1 year period at Korea University Hospital. 1. 92 cases(93.9%) of the total 98 cases were successful and can be obtained the excellent results in soft tissue free-flap transfer. 2. While there were no clinically significant differences in survival rate of flaps transferred from different potential flap donor sites,3 cases of 9 groin flaps were showed higher failure rate due to the complications such as arterial thrombosis, infection and anatomical variation of vessels. 3. Postoperative thrombectomy was performed in 30 cases to be occured in the arterial and venous thrombosis. The revision was failed in 2 cases due to persistent arterial thrombosis and infection, then treated with skin graft. 4. Vein graft was frequently required in severely compromised-soft tissue defects resulted from high-energy trauma. The vein graft was not stitistically significant on the frequency of flap failure rate(P<0.04). 5. Meticulous monitoring, careful planning, early revision and technical considerations will provide for a high clinical success of the free-flap transfer.

Purpose: Distally based superficial sural artery island flap has some disadvantages such as postoperative flap edema, congestion, and partial necrosis of the flap margin. Venous congestion is an area of considerable concern in distally based superficial sural artery fasciocutaneous flap and is one of the main reasons for failure, particularly when a large flap is needed. However, we could decrease these disadvantages by means of venous superdrainage. Methods: From June of 2006 to June of 2007, a total of two patients with soft tissue defects of lower one third of the leg underwent venous supercharging distally based superficial sural artery island flap transfer. The distal pivot point of this flap was designed at septocutaneous perforator from the peroneal artery of the posterolateral septum, which was 5 cm above the tip of the lateral malleolus. Briefly, this technique is performed by anastomosing the proximal end of the lesser saphenous vein and collateral vein to any vein in the area of the recipient defect site. Results: No venous congestion was noted in any of the two cases. No other recipient or donor-site complications were observed, except for minor wound dehiscence in one case. In 3 to 6 months follow-up, patients had minor complaints about lack of sensation in the lateral dorsal foot. Conclusion: The peroneal artery perforator is predictable and reliable for the design of a distally based superficial sural artery island flap. Elevation of the venous supercharging flap is safe, easy, and less time consuming. In conclusion, the venous supercharging distally based superficial sural artery island flap offers an alterative to free tissue transfer for reconstruction of the lower extremity.

Background A thin perforator flap is one of the best methods for covering defects. This study aimed to revisit and further test the rapidly advancing field of flap thinning techniques. Methods We performed two cadaveric studies to test the known flap thinning methods, and then applied these methods to a clinical series. In the first study, five cadavers were used to observe the anatomical relation of the perforator with the subdermal plexuses and the subcutaneous fat layer by injecting a colored latex solution. The second study was done on four cadavers independently from the first study. Last, a clinical series was performed on 15 patients. Results The areolar fat lobules of 10 anterolateral thigh perforator (ALT), seven deep inferior epigastric artery perforator (DIEAP), and six thoracodorsal artery perforator (TAP) flaps were dissected to reduce the flap thickness guided by the colored vascular pattern. On average, the ALT, DIEAP, and TAP flaps were reduced to $32.76%{\pm}9.76%$, $37.01%{\pm}9.21%$, and $35.42%{\pm}9.41%$, respectively. In the second study, the areolar fat lobules were directly dissected in six ALT, six TAP, and four MSAP flaps, and an average reduction in flap thickness of $53.41%{\pm}5.64%$, $52.30%{\pm}2.88%$, and $47.87%{\pm}6.41%$, respectively, was found. In the clinical series, 13 out of the 15 cases yielded satisfactory outcomes with an average thickness reduction of $37.91%{\pm}7.15%$. Conclusions These multiple studies showed that the deep fat layer could be safely removed to obtain a thin yet viable perforator flap. This evidence suggests that the macroscopic flap thinning technique can achieve thin flaps. Surgeons should consider this technique before embracing the latest technique of supermicrosurgery.

Purpose: Low - molecular - weight dextran is one of the most frequently used antithrombotic agents in microvascular surgery, but there is controversy if it has the real benefit in the clinical aspects. The purpose of this study was to evaluate the effect associated with postoperative use of low - molecular - weight dextran in breast reconstruction by free TRAM flap patients. Methods: From January 2002 to October 2008, we reconstructed 88 cases of postmastectomy deformity using the free TRAM flap. The 88 cases were divided into two groups : a group with no use of dextran(66 patients, control group, Group A) and a postoperative low - molecular weight dextran loaded group(22 patients, Group B). We assessed number of flap survival, rate of complication like hematoma or seroma, total amount of drainage from operative wound, duration of drainage, and amount of transfusion in each group. Results: There was no total flap loss and every flap was survived. Total amount of drainage for post - operative 5 days were 857 ml in group A and 1101 ml in group B. Drain was kept for average of 7.3 days in group A and 8.7 days in group B. Packed red cell transfusions were made in average of 3.3 units for group A and 3.0 units for group B. Group B showed significantly higher values in former 2 comparative parameters than group A. Conclusion: There was no definitive advantage of anticoagulants in elective free - flap surgery in terms of success rate. However, groups with using anticoagulants had the increased bleeding tendency in immediate postoperative period. The routine use of anticoagulants in elective free - flap surgery should be reconsidered with postoperatively less bleeding and early recovery.
