Hyperbaric oxygen therapy and surgical delay improve flap survival of reverse pedicle flaps for lower third leg and foot reconstruction

Aim:The purpose of the study is to present a management protocol for various types of soft tissue defects of the distal third region of leg and foot treated with pedicle flaps,by including hyperbaric oxygen(HBO)therapy in the treatment regimen with flap delay.Methods:We present a prospective study of 23 patients with various types of soft tissue defects of the foot,and lower third of leg managed in our institution from December 2012 to December 2013.All soft tissue defects were treated by a reverse pedicle flap.Twelve patients were managed with flap delay with HBO therapy and 11 patients with immediate flaps without HBO therapy.The postoperative period,hospital course,and follow-up were documented.Results:Of 12 patients with flap delay and HBO,10 patients did not suffer any complications secondary to flap transfer.One patient had discoloration of the tip of the flap,which settled without the intervention,and 1 patient had recurrent abscess formation,which required debridement and closure.Of 11 patients with direct transfer,6 patients presented with complications including flap congestion,partial flap loss,and tip necrosis,which required secondary intervention.Conclusion:HBO therapy is a useful adjunct in flap delay of the reverse pedicle flap for soft tissue reconstruction of the lower third of the leg and foot regions.

Preliminary study on the efficacy of lacrimal duct reconstruction with pedicled conjunctival flap in the treatment of severe lacrimal canalicular obstruction with conjunctivochalasis

AIM:To determine the efficacy and safety of pedicled conjunctival lacrimal duct reconstruction in the treatment of severe obstruction of superior and inferior lacrimal canaliculi with conjunctivochalasis.METHODS:This study was per formed as a retrospective analysis of patients who received conjunctival dacryocystorhinostomy with pedicled conjunctival flap reconstruction combined with tube intubation due to severe superior and inferior lacrimal canalicular obstruction with conjunctivochalasis from January 2019 to October 2019.The clinical data included the degree of preoperative epiphora and postoperative relief,preoperative examination of lacrimal duct computed tomography and ultrasound biomicroscopy,postoperative evaluation of lacrimal duct function by chloramphenicol taste and fluorescein dye disappearance test,etc.Syringing was carried out to determine the reconstruction and patency of the lacrimal duct.RESULTS:All 9 patients(9 eyes)had severe canalicular obstruction with conjunctivochalasis.The patients included 4 males and 5 females aged between 47–65y with an average age of 52.2±6.7y.At 3mo follow-up,the tube was removed and the patients were followed for a further 3mo.After tube removal,6 patients showed no epiphora.These patients also had positive chloramphenicol tastes and normal fluorescein dye disappearance test results.Two patientshad epiphora.Also,syringing showed partial patency of the reconstructed lacrimal duct.One patient had no improvement in epiphora with negative chloramphenicol taste and fluorescein dye disappearance test results and obstruction of the reconstructed lacrimal duct.The total effective rate of the operation was 8/9,with no serious complications.CONCLUSION:Pedicled conjunctival lacrimal duct reconstruction conjunctival dacryocystorhinostomy is safe and effective for superior and inferior canalicular obstruction with conjunctivochalasis.

Surgical Reconstruction of a Large Defect after Excision of Infiltrative Squamous Cell Carcinoma in the Scalp and Occipital Region: A Case Report

Squamous cell carcinoma(SCC)of the scalp is the second most prevalent skin cancer,following basal cell carcinoma.Notably,it has the capability to infiltrate the skull,dura mater,and even brain tissue.The cornerstone of treatment is the surgical removal of the lesion,with a particular focus on the depth of invasion,which is directly correlated with recurrence rates.Post-surgical strategies may involve immediate or delayed cranial bone reconstruction and repair of scalp defects using either artificial dermis or skin grafts.In the case presented,a substantial defect necessitated more than a single flap for primary repair.Hence,a single pedicle double-island flap was designed for reconstructing the occipital area.Due to increased tension on the flap following cranial bone repair,the bone repair was temporarily deferred.Postoperative care included adjuvant chemotherapy and radiotherapy to mitigate the risk of SCC recurrence.

Soft tissue coverage using pedicled flap in combat zone: A case series

Background:Soft tissue reconstruction is typically conducted after evacuation from theater of operations.If circumstances do not allow timely evacuation,however,defect site may need to be reconstructed in the combat zone.Case presentation:A total of 41 patients with extremity soft tissue defect were treated using pedicled flaps by a single orthopedic surgeon during four deployments in Chad,Afghanistan and Mali between 2010 and 2017.The mean age was 25.6 years.A total of 46 injury sites in extremities required flap coverage:19 combat-related injuries(CRIs)and 27 non-combat related injuries(NCRIs).Twenty of the injury sites were infected.Overall,63 pedicled flap transfers were carried out:15 muscle flaps,35 local fasciocutaneous flaps and 13 distant fasciocutaneous flaps.The flap types used did not differ for CRIs or NCRIs.Mean follow-up was 71 days.Complications included deep infection(n=6),flap failure(n=1)and partial flap necrosis(n=1).Limb salvage rate was 92.7%(38/41).Conclusions:Soft tissue defect can be managed with simple pedicled flaps in theatre of operations if needed.Basic reconstructive procedures should be part of the training for military orthopedic surgeons.Trial registration:Retrospectively registered in January 2019(2019-0901-001).

Conclusion: The subcutaneous island pedicle flap may be an extremely versatile and reliable method for aesthetic reconstruction of medium-sized facial defects in the patients of all time of life.

Pedicle complex tissue flap transfer for reconstruction of duplicated thumbs with unequal size

BACKGROUND Thumb polydactyly is one of the most common congenital hand deformities,and the Bilhaut-Cloquet procedure or a modified one is often used.However,controversy remains over the rare instances in which both thumbs are not of similar length or far apart in distance.AIM To evaluate the clinical outcomes of pedicle complex tissue flap transfer in the treatment of duplicated thumbs with unequal size.METHODS From January 2014 to December 2020,15 patients underwent duplicated thumb reconstruction by pedicle complex tissue flap transfer at our hand surgery center.The technique was used when it was necessary to combine different tissues from both severed and preserved thumbs that were not of similar length or far apart in distance.Subjective parents’evaluations and functional outcomes(ALURRA and TATA criteria)were obtained.The alignment deviation,instability,range of motion(percent of opposite thumb)of the interphalangeal and metacarpophalangeal joints,and the aesthetic aspects,including circumference,length,nail size,and nail deformity,were used to assess the clinical outcomes.RESULTS The average age of patients at the time of surgery was 13 mo,and the mean final follow-up occurred at 42 mo.An appropriate volume with a stable joint and good appearance was obtained in 14 reconstructed thumbs.An unstable interphalangeal joint occurred in one thumb.The flexion-extension arc at the metacarpophalangeal joint was good,while that at the interphalangeal joint was poor.Most of the parents were satisfied with the cosmetic and functional results of the reconstructed thumbs.The mean ALURRA score was 21.8(range:20-24),and the Tada score was 6.9(range:5-8).Compared with the non-operated side,the length of the operated thumb was approximately 95%,the girth was 89%,and the nail width was 82.9%.The mean ranges of motion were 62.1%of that of the unaffected thumb in the interphalangeal joint and 78.3%in the metacarpophalangeal joint.CONCLUSION Harvesting a pedicle flap from a severed thumb is a safe and reliable procedure.Defects of the preserved thumb,such as the skin,nail,and bone,can be effectively restored using the complex tissue flap.

Supraclavicular artery island flap for reconstruction of hypopharynx and upper esophagus defects:A case report and literature review

We report a case of a 74-year-old female with hypopharyngeal cancer who developed a pharyngoesophageal fistula and neck skin defect after total laryngectomy.To reconstruct the hypopharynx,upper esophagus,and neck skin defect,we used a supraclavicular artery island flap(SCAIF)for one-stage reconstruction.SCAIF offered reliable blood supply,minimal donor site morbidity,and excellent cosmetic outcomes.Although a small portion of the flap developed necrosis,it healed without surgical intervention.We also conducted a literature review of previously published articles on SCAIF for head and neck reconstruction.Our review highlights the advantages and limitations of SCAIF as a promising option for one-stage reconstruction of complex hypopharyngeal and upper esophageal defects with neck skin defects in selected patients.This case report provides valuable insights into the use of SCAIF in complex head and neck reconstructions,which can help improve patient outcomes and quality of life.

Diaphragmatic Flap: Technique of Preparation and Indications for Use

Background: The use of a vascularized pedicle flap of diaphragmatic muscle (DF) for reconstructive procedures in the chest has many advantages. Yet, despite the excellent reported results, the use of DF has not been widespread. Some factors for the less widespread use of DF have been, concern about diaphragmatic function, hesitation to use such a vital muscle for reconstructive purposes, and most importantly, the technical aspects for the preparation of the flap. Methods: Using a cadaveric model, the vascular anatomy of the diaphragm and the steps for the preparation of the DF was defined and illustrated for both the right and left hemidiaphragm. Results: No perioperative mortality with the use of DF has been recorded. Function of the native diaphragm has not been impaired. Bronchopleural fistulas and pericardial defects have healed in all instances. Excellent repair has been achieved in all patients with esophageal lesions. The disruption of the repaired native diaphragm and visceral herniation has been reported but it has been attributed to the learning curve and the technique of repair. Conclusion: With a better understanding of the vascular anatomy of the diaphragm and a formal methodical approach to harvesting the DF, more surgeons will be encouraged to use DF with excellent results.

Penile Skin Flap Urethroplasty for Urethral Stenosis at SominéDOLO Hospital of Mopti (MALI)

Introduction: Penile skin flap urethroplasty is a technique for replacing or enlarging an obstructed urethra. We aim to report our experience in the practice of this surgical technique. Patients and method: This was a prospective and descriptive study of penile skin flap urethroplasty indicated for urethral stenosis between January 2014 and December 2019. Results: A total of 21 penile skin flap urethroplasties for urethral stenosis were performed. The average age was 38.6 years old. The stenosis was of sclero-inflammatory origin in 15 cases (71.43%). It was of bulbo-perineal, penile, and penile-bulbar topography in about a third each. A history of urethral surgery was reported in 80.95% of the cases. The average length of the stenosis was 6.8 cm. Mundy circular skin flap urethroplasty about 15 cases (71.43%), and Quartey rectangular skin penile flap urethroplasty about 6 cases (28.57%) were the surgical techniques performed. The postoperative follow-up was favorable in 19 cases (90.48%). Two cases of urethral fistula (9.52%) underwent the 2nd urethroplasty. Urination at 1 year was satisfactory. No relapse has been reported to date. However, 4 patients (19.04%) reported asthenic ejaculation, and 1 patient (4.76%) a marked decrease in sexual pleasure. Conclusion: This surgical technique is effective in terms of voiding when the surgical indications are well chosen. The sexual aspect must be taken into account and the intervention only offered to those who really need it.

Aesthetic reconstruction of the severely disfigured burned face:a creative strategy for a"natural"appearance using pre-patterned autogenous free flaps

The author reviews his pioneering work in aesthetic restoration of the severely disfigured burn face first introduced in 1995 and refined over the past two decades. The reader will be exposed to the step by step approach to achieving cosmetic enhancement and functional rehabilitation of advanced facial burns. The"keystone"of the autogenous reconstruction is the pre-patterned, sculpted microvascular free flap designed to fit like the"piece of a puzzle"into the aesthetic units of the face to replace disfiguring burn scars. Aggressive intraoperative"sculpting"is employed both"in situ"at the donor site and during the flap transfer to simulate the normal facial contours and planes. Comparisons of the author's approach are made to the whole spectrum of reconstructive modalities ranging from conventional grafting to expanded pre-fabricated flaps and even to CTA face transplants;advantages/disadvantages of each are discussed. The pre-patterned, sculpted microvascular (MV) free flap offers the benefit of a single-stage transfer of composite skin/soft tissue hiding the seams at the junction of facial planes. When harvested from distant donor sites, the donor deformities can easily be concealed. The MV free tissue transfer offers the substrate that can be sculpted into nuanced facial components as well as the"palette"upon which the face can be painted with creative camouflage makeup. The soft contour and texture of the autogenous patterned transfers translates into a"natural"facial appearance while preserving fluid motions of facial expression.

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.
