[The Place of Groin, Colson and McGregor Flaps in the Acute Care of Deep Burns to the Hand Dorsum : A Series of 6 Cases In Lille's Burn Centre]. / Place Des Lambeaux Inguinaux Et Des Empochements Dans La Prise En Charge Aiguë Des Brûlures Profondes Du Dorsum De Main: Série De 6 Cas Au Centre De Traitement Des Brûlés De Lille.

The acute management of deep burns to the dorsum of the hand and fingers represents a challenge for the reconstructive surgeon. The exposure of osteo-tendinous structures often requires flap coverage, in a context where loco-regional or free flaps are not always feasible. The aims of reconstruction are to preserve a maximum of digital length, provide supple tissue, obtain protective sensitivity, and achieve a functional hand at 1 year. We report here on a series of 8 deep burns to the dorsum of the hand. Six hands were covered by Colson abdominal flap-graft and two by pedicled inguinal flap. Four out of 6 patients were reviewed in consultation, 1 patient was lost to follow-up, and 1 patient died. Clinical evaluation was performed by a surgeon other than the operator. Functional results are highly variable. Coverage time varies according to lesion depth and patient severity. Flap weaning took place at an average of 30 days. DASH scores ranged from 17.5 to 93/100, with average to poor total active motion (TAM) scores. The aesthetic result was satisfactory, with a Vancouver score of 4.5/13 on average, and an overall patient opinion of 3.75/10 on the POSAS scale. For deep burns to the dorsum of the hand and fingers, local flaps are rarely possible, and loco-regional flaps are not feasible in cases of associated upper limb damage. For medium to large surface areas, pedicled inguinal flaps and pocketing are two reliable techniques. Nevertheless, they require relative immobilization of the upper limb, which leads to stiffness. The question of digital pinning in the intrinsic or straight position remains unresolved, and does not appear to prevent secondary deformities. There is also a learning curve for these two flaps, even though they are reputed to be easy to lift. McGregor's flap or pocketing can be weighed against free flaps. However, the operating time is long, the surgical technique is complex, and vascular damage is common in the burn patient population. Although there have been enormous technical advances since their descriptions, the pedicled inguinal flap and pocketing remain alternatives to be considered in the acute management of deep burns to the dorsum of the hand. In this presentation, we propose a surgical management algorithm to situate these two techniques in the plastic surgeon's therapeutic armament.

Design and localization algorithm of flap guide plate for jaw defect based on digital 3D printing.

The anterolateral thigh flap is often used to repair the wound tissue defect. Because it is difficult to carry out the perforating vessels before and after the operation, it is considered to use digital design combined with 3D printing technology to prepare the digital three-dimensional guide plate, and at the same time, the guide plate positioning algorithm is designed according to the error caused by the different placement of the guide plate at the site to be transplanted. First of all, select the patients with jaw defect, make the patient's jaw model, obtain the corresponding plaster working model through 3D scanning, obtain STL data, design the guide plate in combination with Rihnoceros and other software, and print the flap guide plate corresponding to jaw defect with the help of metal powder using 3D printer. Based on sequential CT images, the localization algorithm takes the improved genetic algorithm as the research object, extracts the information of the transplantation area as the parameter space, codes the parameters such as the coordinates of the end points of the flap transplantation, and constructs the target function and fitness function of the transplantation. In the experiment, the soft tissue of the patients with jaw defects can be well repaired based on the guide plate. The positioning algorithm locates the flap graft under the condition of less environmental parameters, and obtains the corresponding diameter parameters.

Modified Colson flap with subcutaneous liposuction for one-stage donor site removal: A case series.

OBJECTIVES: The aim of this study was to evaluate the functional and cosmetic results of an innovative procedure for modified Colson flap-graft consisting of immediate defatting of the flap by a liposuction cannula. METHODS: A cross-sectional study was performed among patients with deep hand burns requiring a modified Colson flap between 2018 and 2021. Outcomes included functional and cosmetic assessment of the hand through a quality-of-life questionnaire, a sensitivity scale and a scar assessment scale. RESULTS: During this period, 7 patients were operated on using our technique. One patient was lost to follow-up; 7 patients with a median age of 44 years were included, with a total of 10 burned hands. The burns were thermal in 5 out of 7 cases and the coverage concerned the whole hand in 50% of the cases. The flaps all received cannula defatting. The median time to flap weaning was 23 days (20 to 30 days). The median follow-up was 16 months. One case required remote flap weaning. The median POSAS (Patient and Observer Scar Assessment Scale) per patient was 4 and 2 per observer. The median BMRCSS (British Medical Research Council Sensory Scale) was 122. One case had recovered S2 sensitivity, the other cases had S3 or S4 sensitivity. CONCLUSION: Immediate defatting is one of the factors in tegumental quality allowing rapid functional recovery of the hand. The cannula defatting technique does not appear to require additional defatting time. The use of the liposuction cannula allows a one-step, homogeneous, and easier defatting, with a lower risk of devascularization.

Comparison of sartorius muscle-pedicle and circumflex iliac deep bone flap grafts in the treatment of early non-traumatic osteonecrosis of femoral head in young adults.

OBJECTIVE: The aim of this study was to retrospectively compare and evaluate the midterm curative effect of two different bone flap grafts in the treatment of early non-traumatic osteonecrosis of the femoral head (ONFH). METHODS: A total of 180 patients (199 hips) with early non-traumatic ONFH received surgical treatment by sartorius muscle-pedicle bone flap graft (SMBF) (104 patients, 64 males and 40 females; mean age 34.67 ± 3.24 years) or circumflex iliac deep bone flap graft (CIDBF) (76 patients, 44 males and 32 females; mean age: 35.54 ± 3.37 years) from July 2004 to July 2009. The comparison between the groups was made with Harris score before and after surgery, length of incision, operative time, amount of bleeding, postoperative X-ray. Association Research Circulation Osseous (ARCO) staging was performed. RESULTS: The preoperative Harris hip score of two groups were 68.26 ± 1.26 and 69.35 ± 1.31, respectively. Patients' ARCO staging indicated 36 hips of stage IIa, 115 hips of stage IIb and 48 hips of stage IIc. The etiology of ONFH mainly including hormones (93 patients), alcohol (64 patients) and other (23 patients). The mean follow-up time of SMBF and CIDBF groups were (51.78 ± 2.35) and (52.73 ± 3.71) months, respectively. The time of removing sutures, operation time, amount of bleeding and length of incision in SMBF group were superior to those in the CIDBF group, and those differences between the SMBF and CIDBF groups were not significant (all p values > 0.28). The Harris score between the two groups was similar after operation and postoperative 12 month, and the difference was not statistically significant (p > 0.05), whereas the difference of the postoperative 24 and 48 months was statistically significant (p Ë‚ 0.05). X-ray analysis showed improvement of osteonecrosis in both two groups after surgery, and as time went on, the total hip amount decreased, the replacement amount increased. CONCLUSION: Both bone flap grafts appear to be effective methods for treatment of early osteonecrosis of femoral head (ARCOⅡ), and the SMBF is a relatively simple technique and easy for mastering, and it is a reliable method for clinical application. LEVEL OF EVIDENCE: Level III, Therapeutic Study.

Continuous Negative Pressure Drain is Associated with Better Outcome: A Randomized Prospective Trial in Plastic Surgery Patients.

BACKGROUND: A randomized prospective trial to compare the effects on minimizing complications using continuous negative pressure drain and intermittent suction mode in plastic surgeries. METHODS: There were 174 cases of stage II post-auricular flap expansion and ear reconstruction, 76 cases of skin expansion flap repair, 56 cases of breast augmentation surgery, 58 cases of abdominoplasty, and 76 cases with free skin grafts. Patients were randomized to intermittent suction mode group (control group) and continuous negative pressure external drain group (intervention group) stratified by surgery types. In the intervention group, different pressure levels were applied according to the surgery types. The drainage volume, the length of time of external drainage, incidence of seroma, flap necrosis, the first intending healing rate and drain-associated bleeding were recorded and compared. RESULTS: Generally, fewer complications and better healing were observed in the intervention group. In patients with stage II post-auricular flap expansion and ear reconstruction, lower incidence of flap necrosis and seroma, higher first intention healing rate, greater drain volume but shorter time of drainage were observed in the intervention group (p < 0.05 for all). Similar results were shown in patients with skin expansion flap repair, breast augmentation, abdominoplasty, and free skin grafts. In patients who underwent free skin grafts, a higher graft success rate and lower graft infection rate were also observed (p < 0.01 for both). No drain-associated bleeding was observed. CONCLUSIONS: A continuous negative pressure drain was associated with better outcomes in patients underwent various plastic surgeries and is a powerful technique in the postoperative management of plastic surgery.

Effectiveness of laser adjunctive therapy for surgical treatment of gingival recession with flap graft techniques: a systematic review and meta-analysis.

Various flap graft techniques in the treatment of gingival recession have already been reported in the literatures for root coverage. Laser therapy has effects of ablative, hemostatic, and decontamination. Therefore, we performed a meta-analysis of randomized controlled trials (RCTs) to compare the efficacy of flap surgery combined with laser with surgery alone for treating gingival recession. The studies were searched from PubMed, Embase, Web of science, and the Cochrane Central Register of Controlled Trials by two reviewers up to August 2017. The quality of RCTs was assessed by Cochrane Handbook. Data were extracted from studies and analyzed by Review Manager 5.3. 95% confidence interval (CI) and risk ratio (RR) were calculated for dichotomous data. Seven RCTs with 173 patients and 296 teeth were included in the meta-analysis. We found no statistically significant differences between two groups in GRD (gingival recession depth) (P = 0.21), GRW (gingival recession width) (P = 0.92), RES (root esthetic score) (P = 0.21), and CRC (complete root coverage) (P = 0.09). Statistically significant differences were found between two groups in the WKT (width of keratinized tissue) (P < 0.0001) and 1-year follow-up of PD (probing depth) (P = 0.03) and CAL (clinical attachment level) (P < 0.00001). The meta-analysis found that surgery with laser therapy provided clinical advantages in terms of WKT and 1-year follow-up of PD and CAL. However, flap graft associated with laser did not offer additional benefit to root coverage and esthetics in treating gingival recession. More long-term studies are required to assess these parameters.

Skin flap vaginal augmentation helps prevent and cure post obstetric fistula repair urine leakage: a critical anatomical analysis.

Our aim was to describe a new surgical method for prophylaxis/cure of post obstetric fistula repair leakage based on restoring vaginal elasticity with Singapore skin flap. The rationale for this operation was based on the integral theory: scarring removes elasticity required for independent function of oppositely acting urethral closure forces so they become 'tethered, forcibly opening the urethra when give the signal to close'. Skin graft restores elasticity and closure. Used prophylactically with Goh type 4 fistula (n = 45), 46% were dry against an expected 19%. In patients with successful fistula closure, still with severe leakage (n = 24), 71% were dry against an expected 26%. TWEETABLE ABSTRACT: Singapore skin flap restores elasticity and prevents and treats incontinence in patients with successful obstetric fistula repair.

[Ring finger reconstruction by Colson's flap]. / Reconstruction d'un arrachement digital par lambeau-greffe de Colson.

Surgical treatment of complete cutaneous ring finger avulsion is a challenge in hand surgery. When replantation of the avulsed fragment is not technically feasible, the surgeon must consider reconstruction of soft tissue. Many surgical techniques have been described. We report a case of complete avulsion of the cutaneous sheath and nail of the fourth finger with preservation of mobility and collateral nerves. The reconstruction of soft tissue was performed by a Colson flap-graft. This simple and reliable technique of reconstruction allowed to obtain a functional and sensitive finger with a satisfactory cosmetic result.

Effect of the surgical treatment on the keloid of mons pubis with postoperative radiotherapy / 中华医学美学美容杂志

Objective To explore an effective surgical treatment to the keloid of mons pubis.Methods From March 2008 to January 2015,local flap and adjacent flap (including ilioinguinal flap and rectus abdominal musculocutaneous flap) were performed,and used to repair the defect after surgical removal of the keloid in 25 patients,and all the patients were received postoperative local radiotherapy,and then chi square test was applied to evaluate the effect in the six aspects,including perineal form,skin color,pubic hair distribution,satisfactory effect,skin texture and sense.Results The local flap group was better than the adjacent flap group in perineal form,skin color,pubic hair distribution,satisfactory effect,but there was no significant difference in skin texture and sense.Conclusions For the keloid of mons pubis,the first choice is local flap graft,which can maintain the normal mons pubis formation as most as possible,while the wound is so large that the local flap cannot work,and therefore the vascular pedicle axial flap should be used.

A Case of Chromomycosis Showing Ulcerative Lesions on Dorsa of Hands / 대한피부과학회지

Chromomycosis is a chronic mycosis of the skin and subcutaneous tissue characterized by a brown, thick-walled, round, nonbudding form of causative fungi in the tissue. We report a case of chromomycosis caused by Fonsecaea pedrosoi in a 56-year-old Korean woman who showed 3 x 4cm sized deep ulcerations on the dorsa of both hands. Histopathologically, chronic granulomatous inflammation and sclerotic cells were observed. Fonsecaea pedrosoi was grown into typical black colonies in fungus culture. She was treated with pedicle flap graft followed by oral itraconazole, and showed clinical improvement.
