Systematic review of partial breast reconstruction with pedicled perforator artery flaps: Clinical, oncological and cosmetic outcomes

Introduction: The use of chest wall perforator flaps (CWPFs) following breast conservation surgery for breast cancer has become a useful tool in the armamentarium of the oncoplastic breast surgeon, however robust evidence for the technique is lacking. The aim of this study was to conduct a systematic review appraising the current evidence for the use of CWPFs, evaluating clinical, oncological and cosmetic outcomes.

Training on skin flap elevation in hand surgery using cadavers embalmed by the saturated salt solution method: effectiveness and usefulness.

Thiel embalmed and fresh-frozen cadavers have been mainly used for hand surgery training. We held a training seminar on skin flap elevation using cadavers embalmed by the saturated salt solution method. This study aimed to evaluate the usefulness of such training and to validate the suitability of saturated salt solution-embalmed cadavers for hand surgery training. Participants were trained in elevation procedures for the oblique triangular, reverse digital artery, reverse radial forearm, and reverse dorsal metacarpal artery flaps. Forty-eight surgeons participated in three seminars (one held in 2017, 2018, and 2019 each). A self-assessment of the participants' confidence levels for their surgical skills was performed before and immediately after the seminar, and the suitability of saturated salt solution-embalmed cadavers was determined in terms of visual perception, tactility, comparison with real-world surgical settings, and usefulness. The confidence level for all skills increased immediately after the seminar. The surgeons reported that the visual perception and tactility of the saturated salt solution-embalmed cadavers were comparable to those of a living body, and the cadavers were rated higher with respect to their usefulness. Hand surgery seminars using cadavers embalmed by the saturated salt solution method are considered useful for training in skin flap techniques.

Clinical application of expanded internal mammary artery perforator flap combined with vascular supercharge in reconstruction of faciocervical scar

Objective: To summarize the clinical experience of expanded internal mammary artery perforator (IMAP) flap combined with vascular supercharge in reconstruction of faciocervical scar. Methods: The retrospective observational study was conducted. From September 2012 to May 2021, 23 patients with postburn or posttraumatic faciocervical scars who met the inclusion criteria were admitted to Shanghai Ninth People's Hospital of Shanghai Jiao Tong University School of Medicine, including 18 males and 5 females, aged from 11 to 58 years, all of whom were reconstructed with expanded IMAP flaps. At the first stage, one or two skin and soft tissue expander (s) with appropriate rated capacity were implanted in the anterior chest area according to the location and size of the scars. The IMAP, thoracic branch of supraclavicular artery, and lateral thoracic artery were preserved during the operation. The skin and soft tissue expanders were inflated with normal saline after the operation. The flaps were transferred during the second stage. The dominant IMAP was determined preoperatively using color Doppler ultrasound (CDU) blood flow detector. The faciocervical scars were removed, forming wounds with areas of 9 cm×7 cm-28 cm×12 cm, and the perforators of superficial temporal artery and vein or facial artery and vein were preserved during the operation. The flaps were designed according to the area and size of the wounds after scar resection with the dominant IMAP as the pedicle. Single-pedicle IMAP flaps were used to repair small and medium-sized wounds. For larger defects, the blood perfusion areas of vessels in the anterior chest were evaluated by indocyanine green angiography (ICGA). In situations where the IMAP was insufficient to nourish the entire flap, double-pedicle flaps were designed by using the thoracic branch of supraclavicular artery or lateral thoracic artery for supercharging. Pedicled or free flap transfer was selected according to the distance between the donor areas and recipient areas. After transplantation of flaps, ICGA was conducted again to evaluate blood perfusion of the flaps. The donor sites of flaps were all closed by suturing directly. Statistics were recorded, including the number, rated capacity, normal saline injection volume, and expansion period of skin and soft tissue expanders, the location of the dominant IMAP, the total number of the flaps used, the number of flaps with different types of vascular pedicles, the flap area, the flap survival after the second stage surgery, the occurrence of common complications in the donor and recipient areas, and the condition of follow-up. Results: Totally 25 skin and soft tissue expanders were used in this group of patients, with rated capacity of 200-500 mL, normal saline injection volume of 855-2 055 mL, and expansion period of 4-16 months. The dominant IMAP was detected in the second intercostal space (20 sides) or the third intercostal space (5 sides) before surgery. A total of 25 expanded flaps were excised, including 2 pedicled IMAP flaps, 11 free IMAP flaps, 4 pedicled thoracic branch of supraclavicular artery+free IMAP flaps, and 8 free IMAP+lateral thoracic artery flaps, with flap areas of 10 cm×8 cm-30 cm×14 cm. After the second stage surgery, tip necrosis of flaps in three patients occurred, which healed after routine dressing changes; one patient developed arterial embolism and local torsion on the vascular pedicle at the anastomosis of IMAP and facial artery, and the blood supply recovered after thrombectomy and vascular re-anastomosis. Fourteen patients underwent flap thinning surgery in 1 month to 6 months after the second stage surgery. The follow-up for 4 months to 9 years showed that all patients had improved appearances of flaps and functions of face and neck and linear scar in the donor sites of flaps, and one female patient had obvious nipple displacement and bilateral breast asymmetry. Conclusions: The expanded IMAP flap is matched in color and texture with that of the face and neck, and its incision causes little damage to the chest donor sites. When combined with vascular supercharge, a double-pedicle flap can be designed flexibly to further enhance the blood supply and expand the flap incision area, which is a good choice for reconstruction of large faciocervical scar.

Study of soft tissue cover in compound lower limb trauma

: Early vascularized soft tissue closure has long been recognized to be essential in achieving eventual infection free union. The question of whether muscle or fasciocutaneous tissue is superior in terms of promoting fracture healing remains unresolved.: To study options of different flaps in compound lower limb trauma and to know the pattern of providing flap cover in our setup. This was prospective observational study conducted in all the cases admitted under orthopaedics department who are hemodynamically stabilised, later referred to our department of plastic surgery for the flap cover. Isolated compound lower limb injuries with or without fractures were included in study.: Among 45 cases one patient (2.2%) had defect in the thigh, two patients had defect around knee (6.6%), nine cases had defect in upper third leg (20%), thirteen patients had defect in middle third leg (28.8%), seventeen patients have defect in lower third leg (37.7%) and three patients had in the foot (6.6%). Cross leg flap were used in 11 cases (24.4%) Gastrocnemius myo-cutaneous flap were used in 9 cases (20%). Fascio-cutaneous flaps superiorly based were used in three cases (6.6%) and Inferiorly based Fasciocutaneous flaps were used in 6 cases (13.3%), Reverse sural artery flap were used in six cases (13.3%) and Lateral premalleolar flap were used in 8 cases (17.7) and Advancement flap done in one case over defect of the thigh (2.2%). In a case with defect over thigh (2.2%). Complications like total flap loss was noted in one case (2.2%) marginal necrosis noted in five cases (11.1%) and pin track infection in three cases (6.6%).In Grade IIIB fractures external fixator was the choice of skeletal stabilisation. Delayed flap cover gave good results but it increases duration of hospital stay.

Different surgical procedures for reconstruction of soft-tissue defects around the ankle

IntroductionManagement of soft tissue defects around the ankle is a difficult and challenging situation for all reconstructive surgeons. A microsurgical free flaps coverage can solve this problematic situation especially with large defects that is not available in all trauma centers. Moreover, long operating time and suitable operative demands are considered obstacles. Materials and methodEighty five patients having soft tissue defects around ankle were included in this study. They underwent various reconstructions in our specialized hand and reconstructive microsurgery unit from 2015 to 2019. Fifty two were males and thirty three patients were females. Road traffic accident was the main cause of injury in 66 patients followed by implant exposure in 15 patients and chronic osteomyelitis in 4 patients. Distally based superficial sural artery flap was used to reconstruct the defects in 21 cases, free flap was used in 32 cases, Rotational local flap was used in 8 cases, contralateral distally based superficial sural artery flap was used in 2 cases, full or partial skin flaps were used in 10 cases and Propeller flap was used in 12cases. ResultsAll flaps survived except for one modified sural flap with 98% success rate and average follow up of 48 months. All patients were satisfied with the functional capacity of operated limbs. Average time of bone healing postoperative was 3 months with gradual return to original work with acceptable degrees for cosmotic appearance of the limbs. ConclusionMany treatment options are available to cover defects around the ankle. Propeller and rotational flaps are fast and easy but cover small defects, distally-based modified sural artery flap is an excellent reliable flap. Microsurgical free flaps provide good contour, color, texture and cover large defects but require microsurgery facilities to execute.

A Comprehensive Review on the Supraclavicular Flap for Head and Neck Reconstruction.

The supraclavicular artery flap (SCF) is a highly vascularized fasciocutaneous flap overlying the shoulder. The flap was first described in 1979 by Lamberty but did not gain popularity until much later due to lack of a reliable technique. The main advantages of using the SCF include avoiding microsurgical techniques, requiring only a single-stage operation, shorter operative time compared with alternative options, and a wider patient population including those with comorbidities who may be excluded from more extensive operations including free flaps surgeries. The SCF has been successfully performed on individuals with advanced age, poor nutrition, cachexia, obesity, diabetes, tobacco use, severe chronic obstructive pulmonary disease, hypertension, coronary artery disease, peripheral vascular disease, supraventricular tachycardia, atrial fibrillation, heart failure, asthma, and steroid use. The largest disadvantages of the SCF include the possibility of distal tip necrosis, size limitation without pre-expansion, and a moderately visible donor site scar. The following review and meta-analysis of the SCF details its use historically as both an island and a pedicle flap, and its application in head and neck reconstruction.

A Comparison of Outcomes of Reconstruction of Palmar versus Dorsal Defects of the Thumb Using a First Dorsal Metacarpal Artery Flap with a Cutaneous Bridge Segment.

Background: The aim of this study is to compare outcomes of reconstruction of palmar versus dorsal defects of the thumb using the first dorsal metacarpal artery (FDMA) flap with a cutaneous bridge segment. Methods: All FDMA flaps done at our centre for reconstruction of traumatic thumb defects in the period from November 2017 to May 2019 were included in this study. Data with regard to the patient, the injury and the flap were recorded. The outcome measures recorded include flap survival, complications, duration of follow-up, static two-point discrimination (2-PD), cortical reorientation, paresthesia at the flap and donor site, pain at the flap and donor site, Kapandji score and aesthetic outcome. Results: The study included 11 patients with an average age of 35 years. All patients were men, and the injury involved the dominant thumb in seven patients. There were five dorsal defects and six palmar defects, and the average defect size was 7.22 sq cm. All flaps survived and there were no complications. The mean follow-up period was 15.2 months. The mean static 2-PD was 9.35 mm, cortical reorientation was complete in six patients, paresthesia score at the flap was 0.27 and at the donor site was 0.36. The visual analogue scale (VAS) pain for the flap was 1.09 and for the donor site was 1.27. The average Kapandji score was 8.64 and patients rated the aesthetic outcome of the flap at 8 and of the donor site at 7.36. There were no differences in outcomes between palmar and dorsal defects except for the aesthetic outcome of the flap that was rated better for dorsal defects. Conclusion: The FDMA flap designed with a cutaneous bridge segment provided reliable, single-stage reconstruction of dorsal and palmar thumb defects with good outcomes. Patients rated the aesthetic outcome of flaps used for dorsal reconstruction higher. Level of evidence: Level IV (Therapeutic).

Distally Based Sural Flap in Children: Experience in Our Department

The reverse sural artery flap (RSAF) was first described approximately four decades ago in 1983 by Donski and Fogdestam [1] and has since been used frequently for reconstruction of soft tissue defects in the distal part of the leg. Coverage of soft-tissue defects of the ankle and foot is often challenging. The distally based sural fascio-cutaneous flap is useful for reconstructing the lower leg, ankle, heel, and foot but has rarely been evaluated in paediatric patients. The objectives of this study were to assess the reliability of this flap in children, to get a global experience with the sural flap in our department of plastic and reconstructive pediatric surgery, and to describe the complications. Material and methods: A distally based sural fascio-cutaneous flap was used to cover soft-tissue defects of the ankle and foot in 5 paediatric patients between 2018 and 2021. The median age of patient at surgery was 6 years old. The most frequent mechanism of soft tissue defect was trauma caused by vehicular accident (open fractures) crush injuries, lacerated wound. Results: One of the 5 flaps was a cross leg sural flap, 4 recovered well without necrosis, only one developed partial necrosis requiring excision and skin grafting. The other complications where an early postoperative complications: partial or total necrosis of the flap late complications including impaired touch sensation over the flap and donorsite. Discussion: The distally based sural fascio-cutaneous flap is a method of choice for covering soft-tissue defects of the ankle and foot in paediatric patients. This reliable flap spares the major blood vessels and has a good blood supply. When there is exposure of a vital structure, distal sural flap is the best indication for coverage in a traumatic soft-tissue defect. The use of a distally based sural fascio cutaneous flap is not free from delayed complications most of them at the donor site.

Donor Site Morbidity in Patients Undergoing Maxillofacial Reconstruction Using Free Fibula Flap Versus Deep Circumflex Artery Flap-A Systematic Review.

A systematic review of the literature on the donor site morbidity in patients undergoing Maxillofacial reconstruction was performed. The two widely used flaps namely free fibula flap (FFF) and DCIA flap were compared to answer the following questions: (1) Is donor site morbidity significantly different in patients undergoing maxillofacial reconstruction with FFF and DCIA flap? (2) Should donor site morbidity be considered as the criteria for choosing the flap for reconstruction. The search strategy was based on PRISMA guidelines. Various electronic databases were searched. On reviewing the seven articles included in our systematic review, we found out oral squamous cell carcinoma to be the most common pathology leading to the defects in head and neck region requiring reconstruction with free flaps. A total of 531 participants were investigated who underwent maxillofacial reconstruction using FFF and DCIA flap. The study included both the genders. The participants were assessed for short- and long-term donor site morbidity after the microvascular surgery. Mean age is 45-60 years. Three out of seven studies showed DCIA to have lesser complications at donor site than fibula group. While other two studies proved FFF to be better than DCIA. One study proved low donor site morbidity with regard to both the flap. The free fibula being the flap of choice in head and neck reconstruction has a comparable donor site morbidity to DCIA. The advantages of the iliac artery flap include natural curvature, abundant vertical and horizontal bone height for bone contouring and osseointegration, hidden scar, low incidence of wound healing problems and minimal effect on function and quality of life at long-term follow-up. Thus, it makes it the free flap of choice that one cannot avoid. This systematic review was registered at PROSPERO (CRD42021268949).

Vascularized lymph vessel transplant (VLVT): our experience and lymphedema treatment algorithm

: Supermicrosurgical lymphaticovenicular anastomosis (LVA) and vascularized lymph node transplant (VLNT) are established surgical procedures for fluid-predominant extremity lymphedema. LVA is most effective for early disease, while VLNT is effective for more advanced lymphatic injury. However, the devastating complication of donor-site lymphedema has been reported following VLNT. Contour deformity caused by the bulky VLNT flaps further decreases the appeal of this procedure. Vascularized lymph vessel transplant (VLVT) has emerged as a promising new alternative to VLNT. This novel technique has challenged the accepted belief that incorporation of lymph nodes (LNs) into a flap is necessary for the physiologic treatment of advanced lymphedema. First described with the first dorsal metatarsal artery (FDMA) flap, the superficial circumflex iliac artery perforator (SCIP) and thoracodorsal artery perforator (TDAP) flaps were later on described as additional options for VLVT. Outcomes of VLVT have been found to be mostly equivalent to those of VLNT in alleviating symptoms and improving quality of life (QoL). By not sacrificing LNs, it theoretically reduces donor site morbidity. To date, donor-site lymphedema as a sequela of VLVT harvest has not been reported. As with other modalities for the treatment of lymphedema, an understanding of the progression of this disease and careful patient selection is imperative for the successful implementation of VLVT. A review of the literature, combined with the senior author’s experience with these novel techniques, was utilized to generate an updated algorithm for the surgical treatment of extremity lymphedema.

Quantification and Further Refinement of Lateral Calcaneal Artery Flap for Complicated Heel Defect Reconstruction.

Background:Reconstruction of posterior heel defects requires tissues with adequate blood supply, good elasticity, and sensate; because of the traumatic origin in the young population, it ends up with morbidity. The lateral calcaneal artery is the arterial supply of the lateral calcaneal artery flap. This is one of the viable choices for coverage of hind foot soft-tissue defects. The objective of this study was to determine the outcome of the lateral calcaneal artery flap in terms of function, donor site morbidity, and duration of surgery.Method:This was a descriptive case series. Patients with complicated heel defects of small to medium size were included. The follow-up period was 6 months to 1 year of posttreatment. Outcome measures were noted and assessed in all patients in terms of function, donor area morbidity, and total duration of surgery. Significance was determined by assessing the gait, donor site pain, physical appearance at the surgical site, and time needed for surgery.Results:Twelve patients [men: eight (62.5%), women: four (37.5%)] were selected for this study, with their mean age being 14.4 ± 7.4 years. Mean defect size was (4.4 ± 0.5) cm. Mean flap size was 3.5–5.5 cm (P < 0.001). There was a near-normal gait in all patients, with a pain score of (0–2) on the visual analogue scale score, physical appearance by Vancouver scar scale score (0–3), and the mean duration of surgery was 45 ± 4.5 minutes.Conclusion:The lateral calcaneal artery flap is more effective for reconstruction of posterior heel and tendon Achilles defects in terms of function, donor area morbidity, and duration of surgery.

ALTERING THE MARKING OF THE REVERSE POSTERIOR INTEROSSEOUS ARTERY FLAP

BackgroundFull-thickness defects on the dorsum of the hand requires thin, soft, and pliable skin for which there are limited locoregional flaps. The reverse posterior interosseous artery (PIA) flap based on the communicating artery fulfills all above requirements and can reach upto the fingers. However, there has been discrepancy in the surface marking of the flap and the anatomical position of the vessel pedicle. We share our alteration with the marking and ease of harvesting this flap.Method and materialThis is a prospective study conducted at a private teaching hospital in Karachi, over a period of 2 years from November 2017 to December 2019. After taking consent and ensuring confidentiality of all patients who had PIA flap reconstruction, we collected patient's demographic details, mode of injury, and flap surface area. We altered the described skin marking and took measures to prevent venous congestion and noted the outcomes in term of flap congestion and flap loss.ResultsTwenty-eight patients with a mode age of 32 years were operated during this period. The majority (64.2%) had a motor vehicle accident and machine injuries. The mean surface area of flaps was 6 × 10 cm2, and 11 (39.2%) flaps had venous supercharging. All patients had a 10-20° wrist extension splint for 2 weeks. The mean follow-up of the patients was 14 ± 5 days, and 6 (21.4%) flaps developed a minimal marginal flap loss, which was managed conservatively.ConclusionBy minimally altering our surface marking, we experienced a easy and quick harvesting of this flap. However, one has to be vigilant and take all described precautions for venous congestion.

Medial plantar artery-based perforator and island flaps: a case series of applications in sole defects.

Soft tissue defects of the plantar foot pose a challenge to the reconstructive surgeon. The plantar region of the foot has a unique skin structure, which helps in its paramount functions of weight-bearing and providing protective sensation. It is best replaced with tissue of its own kind. The medial plantar artery (MPA) flap fulfils all the requirements of an ideal replacement for small-to-medium-sized defects in the mid plantar and heel region. This study describes our experience with MPA-based flaps for small-to-medium-sized defects of the plantar foot. The study was conducted in a tertiary referral hospital between April 2017 and March 2020 on patients who presented with defects on the mid plantar region and heel. MPA perforator (MPAP) flap or island flap were applied. The donor site was covered with split-thickness skin grafts. The study included 21 patients. MPAP flap was applied in nine patients and the island flap was applied in 12 patients. The mean age of the patients was 37.95 years and the mean flap size was 36.6cm2. All flaps survived well. In two patients, venous congestion developed which resolved spontaneously, while three patients had small graft loss which also healed with conservative treatment. All patients regained protective sensation within five months of flap coverage. Based on the MPA, both perforator and island flaps can be raised due to the fairly constant position of the perforators. These flaps have the advantage of robust vascularity with the replacement of identical tissue for weight-bearing functions along with acceptable aesthetic outcomes. Since they also have the added advantage of conferring sensation, they can be used as a primary option in cases of small-to-medium-sized plantar foot defects.

Harvesting Composite Arterial and Vein Grafts from Deep Inferior Epigastric Artery and Vein: A Safe Five-Step Method of Preparation.

As the use of stacked flaps and options for autologous breast reconstruction increase, the level of complexity in autologous breast reconstruction has risen. Frequently, these reconstruction types present technical challenges such as vessel mismatches and short pedicle length. In this study, the authors introduce their five steps of harvesting composite deep inferior epigastric artery (DIEA) and deep inferior epigastric vein (DIEV) grafts to overcome such challenges. The authors performed a retrospective review of patients who underwent microvascular reconstruction using DIEA/DIEV grafts from 2012 to 2020. The grafts were harvested using the five steps, as follows: step 1, a transverse, paramedian skin incision was made at the level of suprapubic crease; step 2, an oblique fasciotomy was made on the lateral rectus border; step 3, DIEA/DIEV vessels were identified and exposed past the confluence of two venae comitantes; step 4, DIEA/DIEV grafts were harvested while sparing motor nerves; and step 5, fascial closure was performed. A total of 40 DIEA/DIEV grafts were used in 25 patients (lumbar artery perforator flaps, n = 25; lateral thigh flaps, n = 1; superficial inferior epigastric artery flaps, n = 12; and flap salvage, n = 2) for breast reconstruction. The average time of harvest was 28 minutes, and there were two flap losses. In the authors' experience, DIEA/DIEV grafts can be safely harvested and used in flaps with short pedicles and small vessel size. Although the authors' experience was limited to breast reconstruction, the DIEA/DIEV grafts can be used for other types of reconstruction, especially for head and neck reconstruction.

Variations in the Pattern of the Deep Palmar Arch of the Hand and Its Surgical Importance.

BackgroundThe deep palmar arch is formed by anastomosis of the continuation of the radial artery with the deep palmar branch of the ulnar artery. With recent advances in microsurgical techniques for vascular repair, the knowledge of variations in the arteries of the hand, as well as the caliber of these arteries, has become more important for surgeons. Additionally, radial artery harvesting for myocardial revascularization is being performed nowadays, for which collateral circulation in the hand through the palmar arches is a prerequisite. Therefore, this study was conducted to study the patterns of the deep palmar arch and perform the morphometry of the arch.MethodologyIn this study, 30 hands (16 right and 14 left) from formalin-fixed adult human cadavers were dissected to observe the completeness, formation, and branching pattern of the deep palmar arch. The length of the arch was measured using a thread and scale. The diameters of the forming arteries and branches of the arch were measured at their origin using a digital vernier caliper.ResultsAll deep palmar arches were complete. The arches were classified into two types based on whether the superior or inferior deep palmar branch of the ulnar artery completed the arch. Another classification was based on the interosseous space through which the radial artery or its branch entered the palmar region to complete the deep palmar arch. The length of the arch was 4.2 ± 0.47 cm on the right side and 4.0 ± 0.6 cm on the left side. The diameters of the deep palmar branch of the radial and ulnar arteries at their origin were 4.02 ± 0.48 mm and 1.90 ± 0.36 mm, respectively. No significant difference was found between the right and left sides.ConclusionsThe anastomosis was found between radial and ulnar arteries in all cases of the deep palmar arch. Therefore, it can be safe to sacrifice the radial artery in procedures such as radial artery harvesting and radial artery flap transfer. The knowledge of variations and morphometry of the arch will facilitate vascular repair surgeries on hands.

The submental island pedicled flap and supraclavicular artery island flap in a free flap practice

Reconstruction of head and neck defects is a delicate endeavor that poses numerous intrinsic and extrinsic challenges, which are currently magnified by rising health care costs and limitations in system resources. Current trends in the United States heavily favor the use of free tissue transfer over locoregional pedicles flaps (LRPF); however, the latter group is often undervalued, offering high utility, practicality, and cost-efficiency whilst providing equivalent results. The submental island flap and supraclavicular artery island flap are two LRPF that should be in the arsenal of the modern reconstructive surgeon.

The superior lateral genicular artery flap for reconstruction of knee and proximal leg defects

Reconstruction of defects around the knee region requires thin and pliable skin. The superior lateral genicular artery (SLGA) flap provides an excellent alternative to muscle-based flaps. The anatomy and the surgical techniques of the SLGA flap were reviewed and the results of cases using the SLGA flap for coverage of knee and proximal leg defects were analyzed. SLGA flaps were performed in two cases and followed up for at least 6 months. Twelve articles on the use of the SLGA flap were also identified. A review of 39 cases showed that the mean diameter of the perforator supplying the skin of the flap was 1.04 mm, while the mean diameter of the SLGA at its origin was 1.78 mm. The mean length of the pedicle measured from the origin of the popliteal artery was 7.44 cm. The average dimensions of the flap were 14.8×6.6 cm with primary closure of the donor site in 61.5% of cases. Of these cases, 38.5% were due to trauma, 23.1% were post-burn complications, 12.8% were defects after resection of tumors, and 10.3% were for ulcers post-bursectomy. The most common complication was flap tip necrosis. All studies reported favorable outcomes with complete wound healing.

Common Modalities of Reconstruction for Scrotal Defects at a Tertiary Care Hospital in Eastern India: An Observational Study

Introduction: Scrotal reconstruction remains a challenging problem to the surgeons. The various techniques used for scrotal reconstruction includes residual tissue re-arrangement, skin grafts, pedicled and free tissue transfer. There is lack of unified approach to deal with the issue. Aim: To discuss the surgical techniques performed for scrotal reconstruction in a tertiary care centre along with its epidemiological factors. Materials and Methods: This observational descriptive study was conducted on 33 cases in a tertiary care centre located in Eastern India over a period of three years. Scrotal reconstruction was planned according to aetiology, defect size, associated co-morbidity and age of the patient. Evaluation to assess the efficacy of each procedure was done with patient’s satisfaction scoring. At the time of discharge, with simple four level Likert scale, patient’s satisfaction was assessed. Descriptive statistics was used and results were expressed in terms of frequency and percentage. Results: The mean age of the patients with scrotal defects was 48±15.98 years. Fournier’s gangrene (n=21) was the leading cause of scrotal defects followed by trauma (n=8). The most common scrotal defect size was 50-75% (n=12). The most common scrotal reconstruction performed was Pudendal artery flap (Singapore flap) (n=12). Donor site scar was limited and acceptable. Wound related complications detected clinically as partial tissue necrosis, was observed in two cases. Most patients were satisfied with the final outcome, assessed by Likert scale. Conclusion: Scrotal reconstruction should be performed taking in account its aetiology, associated comorbidity, age and the scrotal defect size. Aesthetically and psychologically, well planned flap is reliable and better in comparison to Split-Thickness Skin Graft (STSG) and most of the complications can be managed conservatively.

Commentary: The Superior Lateral Genicular Artery Flap for Reconstruction of Knee and Proximal Leg Defects

Commentary: The Superior Lateral Genicular Artery Flap for Reconstruction of Knee and Proximal Leg Defects

Evaluation of versatility and outcomes of the first dorsal metacarpal artery flap in thumb defects.

It is clinically vital to determine the best technique to reconstruct thumb defects with satisfactory esthetic and functional outcomes. We aimed to quantitatively present the safety, versatility, limitations, advantages, and functional results of the first dorsal metacarpal artery flap (FDMAF) and evaluate its outcomes in thumb defect reconstruction by comparing it with the other current surgical options. A total of 21 patients underwent thumb defect reconstruction. They were evaluated with the following parameters: Etiology, age, timing of reconstruction, flap vitality, Semmes-Weinstein monofilament (SWM) test, static two-point discrimination (2PD) test, pain, cortical reorientation, cold intolerance questionnaire, and Michigan hand outcomes questionnaire. Their functional outcomes were evaluated by comparing their scores with the other current surgical options published in the literature. The mean follow-up period was 22.3 months. The mean pain score of the flap was 0.4±0.6 and no patient had pain in the donor area (range, 0-10). The sensory outcome was 'good' (8.6 mm) based on the static 2PD test. The mean SWM test score was 4.02 g. Patient satisfaction was 4.6 according to the Michigan hand outcomes questionnaire (range, 0-5). The cold intolerance questionnaire scores showed that the patients had mild cold intolerance (mean, 10.5; range 0-100). Complete cortical reorientation was seen in 81% of the patients. Restoration of the innervation of thumb defects is possible with the FDMAF with high satisfaction rates based on our results. The absence of the microsurgical vessel or nerve repair facilitates the surgery, shortens its duration, and reduces morbidity, reserving the microsurgical options for more complicated cases. Therefore, it can be concluded that the FDMAF is an effective flap with great modifications for complicated thumb defects but surgeons should consider their clinical outcomes and prolonged surgery when choosing which technique to be used.
