However, for pre-collapse ONFH with extensive necrotic area, it is still challenging to preserve the femoral head. The current study aimed to introduce a new technique of deliquesce strut with titanium mesh containing bone grafting pedicled with the femoral quadratus and to evaluate its short-term outcomes.Methods From January 2008 to December 2008, 10 ONFH patients （12 hips） underwent operations by a new technique of deliquesce strut with titanium mesh containing bone grafting pedicled with the femoral quadratus （group A）.According to the ARCO classification system, there were two hips in stage Ⅱ B and 10 hips in stage Ⅱ C. Also in the same period, 12 ONFH patients （16 hips） underwent operations by the conventional procedure of quadratus femoris pedicled bone grafting （group B）. There were 6 hips in stage Ⅱ B and 10 hips in stage Ⅱ C. All patients were males and suffered from alcohol induced ONFH. For the new technique, the necrotic area was evaluated, and a titanium mesh piece of the same size （range from 2.5 cm×2.8 cm to 2.8 cm×3.4 cm） was obtained and shaped to match the contour of the head. The cancellous bone was first placed underneath the subchondral bone and was densely impacted （about 1 to 2 mm thick）.Then the titanium mesh piece was inserted. The length of the decompressive trough was measured. A titanium cylinder mesh cage with a diameter of 1.6 cm of the same length was obtained, with a ＂U＂ shaped window in the wall being created to make room for the muscle pedicle. The muscle pedicle bone was inserted into the titanium mesh cage to form a bone graft-titanium cage complex and, then the complex was inserted. The hundred percent score method was used for outcome evaluation. Clinical and radiographic outcomes were compared between group A and group B.Results The average展开更多

Varieties of techniques are available for resurfacing defects following contracture release but graft or flap loss, donor-site morbidity, esthetics, and recurrences are still challenges for reconstructive surgeons. Central axis 'propeller' flaps based on a random, subcutaneous pedicle were first described for axillary and elbow contractures to deploy the unburnt skin of axillary dome in type Ⅰ and Ⅱ contractures (Kurtzman and Stern) by moving them 90° to straddle the contracting bands. This strategy provided better esthetics and avoided prolonged splinting. Over more than two decades, there have been several design modifications of these flaps with extended applications to cubital fossa. A comprehensive review of published literature on the topic is presented to discuss classifications, design modifications, and applications of such flaps in managing axillary and elbow contractures.展开更多

Expedient medical care, refinement in surgical techniques, and soft tissue coverage have brought about a paradigm shift in the management of lower extremity wounds during the last decade with an increased emphasis on limb salvage.Methods: A literature-based study was conducted to analyze reconstructive modalities based on the location, depth, and severity of wounds, as well as mechanism of injury, concomitant vascular injuries and open fractures, choice of flap, timing of definitive reconstruction, and complications.Results: Extremity injuries account for over 60% of injuries in the recent conflicts in Iraq and Afghanistan, with the majority secondary to explosive devices. The severity of these injuries is profound compared with civilian registries, and conventional injury scoring systems have failed to accurately predict outcomes in combat trauma. The mainstay of treatment is serial debridement, negative pressure therapy, fracture stabilization, and treatment of concomitant injuries by the forward medical teams with subsequent definitive reconstruction after transport to an advanced military treatment facility. Autologous reconstruction with free tissue transfer and pedicled flaps remains the primary modality for soft tissue coverage in limb salvage. Adjunct innovative modalities, such as external tissue expansion, dermal substitutes, and regenerative matrices, have also been successfully utilized for limb salvage.Conclusion: Lower extremity injuries account for the vast majority of injuries in modern warzones. Explosive devices represent the most common mechanism of injury, with blast impact leading to extensive soft tissue injuries necessitating complex reconstructive strategies. Serial debridement, negative pressure therapy, and autologous reconstruction with free tissue transfer and pedicled flaps remain the mainstay of treatment in recent conflicts.展开更多

A previous redundant flap could be reused or recycled as a donor site from which a new flap could be raised. Case presentation: We report the case of a patient with full thickness burns on both legs, leading to the exposure of joints of the right ankle and the right foot and left patellar tendon. The right lower extremity was covered with a free musculo-cutaneous latissimus dorsi flap. Then, a musculo-cutaneous cross-leg flap pedicled on the anterior branch and centered on a perforator was harvested from the previous redundant flap to cover the controlateral knee. Conclusion: Sequential flap coverage can be considered in cases of extensive soft tissue defects and particularly in burns. This case illustrates that re-using a redundant part of a previous flap to cover another defect is a safe and interesting alternative in the event of a lack of donor sites or to save donor sites for later reconstruction of contracted burn scars.展开更多

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.展开更多

However, techniques in microvascular surgery have since evolved and recently free tissue transfer has played an important role in head and neck reconstruction. Although we use free flaps as the first choice for head and neck reconstruction, similar to many other institutions, some patients at our hospital have undergone reconstruction with PMMC flaps. We retrospectively analyzed the indications and outcomes of this reconstructive technique from our experience with 12 patients. The medical records of all patients who underwent PMMC flaps at Hokkaido Cancer Center from 2001 to 2010 were reviewed. Data concerning diagnosis, main indication, site of reconstruction, previous treatment, and postoperative complications were analyzed. Of the 12 PMMC flap surgeries performed, 3 were carried out as primary reconstructive procedures, whereas 9 were done as “salvage” procedures. Flap-related complications were observed in 6 cases. Partial flap loss developed in 4 patients, although there were no cases of total flap loss. There were 3 recurrent fistulae following reconstruction with PMMC flaps. The preoperative goals of performing PMMC flap surgery were met in 83% of our cases. The authors conclude that while free flap transfer is usually the first choice for head and neck reconstruction, PMMC flaps can produce acceptable results in certain situations.展开更多

ORN usually manifests with pain, exposed bone, fistulae and pathological fracture and the proper management needs proper debridement and coverage by thick musculocutaneous flaps. Objective: To evaluate different techniques of surgical management of post-irradiation persistent radio-necrotic ulcer & ORN with emphasis on the outcome of each technique. Patients and methods: A retrospective study from 2010 to 2015 reviewed 20 patients subjected to post-mastectomy radiotherapy as a treatment for breast cancer inNCICairo, and Minia oncology center Hospital, Egypt. Cases were biopsied to exclude local recurrence. The age, sex, type of ulcer, dose of radiotherapy received and the management done for these cases were recorded. Results: Only 4 patients responded to conservative treatment in the form of repeated dressings, and 16 patients needed surgical treatment;5 of them were treated with debridement and coverage with split thickness graft with high rate of complications reaching 80%, the other 11 patients were reconstructed with musculocutanoeus flaps, of these 7 patients were reconstructed with LD flaps with 57.14% success rate and minor complications only, the other 4 cases were reconstructed with TRAM flap with 50% success and major loss of the flap in one case that needed salvage by LD flap. Pre-operative comorbidity was found in 6 patients and all of them experienced complications while only 3 of the other 14 who had no comorbidity had postoperative complications. Conclusion: Pedicled flaps provide a good choice for reconstruction and provide chest wall support without the use of synthetic mesh.展开更多

We aim to report our experience in the practice of this surgical technique. <strong>Patients and method:</strong> This was a prospective and descriptive study of penile skin flap urethroplasty indicated for urethral stenosis between January 2014 and December 2019. <strong>Results:</strong> 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 2<sup>nd</sup> 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. <strong>Conclusion:</strong> 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.展开更多

The purpose of this series was to review our 10 years’ experience with the PMMF in head and neck reconstruction. One hundred and two patients who underwent the PMMF technique were reviewed on the clinical records. Postoperative complications were classified into flap loss, hemorrhage, infection, fistula formation, wound dehiscence and donor site complication. Eighty two patients (80.4%) demonstrated no complication. Six patients among 102 patients (5.9%) demonstrated total or partial skin necroses. Three female patients were completely dissatisfied with the cosmetic appearance after the PMMF. One of them required a reconstructive surgery with the latissimusdorsi flap. Without surgical expertise in plastic surgical field, an ear-nose-throat or an oral surgeon can performed the PMMF technique provided the operator is well aware of serious and frequent complications of this “workhorse” procedure.展开更多
文摘Background Quadratus femoris pedicled bone grafting has yielded satisfactory long-term clinical outcome for osteonecrosis of the femoral head （ONFH） in pre-collapse ONFH without extensive lesion. However, for pre-collapse ONFH with extensive necrotic area, it is still challenging to preserve the femoral head. The current study aimed to introduce a new technique of deliquesce strut with titanium mesh containing bone grafting pedicled with the femoral quadratus and to evaluate its short-term outcomes.Methods From January 2008 to December 2008, 10 ONFH patients （12 hips） underwent operations by a new technique of deliquesce strut with titanium mesh containing bone grafting pedicled with the femoral quadratus （group A）.According to the ARCO classification system, there were two hips in stage Ⅱ B and 10 hips in stage Ⅱ C. Also in the same period, 12 ONFH patients （16 hips） underwent operations by the conventional procedure of quadratus femoris pedicled bone grafting （group B）. There were 6 hips in stage Ⅱ B and 10 hips in stage Ⅱ C. All patients were males and suffered from alcohol induced ONFH. For the new technique, the necrotic area was evaluated, and a titanium mesh piece of the same size （range from 2.5 cm×2.8 cm to 2.8 cm×3.4 cm） was obtained and shaped to match the contour of the head. The cancellous bone was first placed underneath the subchondral bone and was densely impacted （about 1 to 2 mm thick）.Then the titanium mesh piece was inserted. The length of the decompressive trough was measured. A titanium cylinder mesh cage with a diameter of 1.6 cm of the same length was obtained, with a ＂U＂ shaped window in the wall being created to make room for the muscle pedicle. The muscle pedicle bone was inserted into the titanium mesh cage to form a bone graft-titanium cage complex and, then the complex was inserted. The hundred percent score method was used for outcome evaluation. Clinical and radiographic outcomes were compared between group A and group B.Results The average

文摘Background: In well-selected cases, flaps can play a pivotal role in optimizing outcomes in the acute phase of burns. A previous redundant flap could be reused or recycled as a donor site from which a new flap could be raised. Case presentation: We report the case of a patient with full thickness burns on both legs, leading to the exposure of joints of the right ankle and the right foot and left patellar tendon. The right lower extremity was covered with a free musculo-cutaneous latissimus dorsi flap. Then, a musculo-cutaneous cross-leg flap pedicled on the anterior branch and centered on a perforator was harvested from the previous redundant flap to cover the controlateral knee. Conclusion: Sequential flap coverage can be considered in cases of extensive soft tissue defects and particularly in burns. This case illustrates that re-using a redundant part of a previous flap to cover another defect is a safe and interesting alternative in the event of a lack of donor sites or to save donor sites for later reconstruction of contracted burn scars.

文摘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.
文摘Background Skin lesions on the nose are common.Multiple surgical techniques have been used for nasal reconstruction.These options may be autogenous or alloplastic and can be performed in single or multiple stages.The choice of coverage depends on the nature of the lesion,location on the nose,and available donor sites.This study aimed to evaluate the surgical outcomes of using locoregional flaps for nasal reconstruction.Methods A total of 27 patients underwent surgery.There were 9 men and 18 women,aged 7 months to 93 years.Four patients presented with involuting hemangioma,five patients with ischemic necrosis of the columella,and five patients with congenital nevus;the remaining 13 patients were previously diagnosed with basal cell carcinoma.Six techniques have been described for nasal reconstruction at our institution from 2016 to 2020.Most patients had basal cell carcinoma(n=13).Locoregional flaps and primary sutures were used for nasal reconstruction.Results The complications were minimal.One patient had a superficial infection and one experienced postoperative bleeding.No recurrence was observed,and none of the patients asked for a second opinion.Conclusion Radical excision of tumors combined with analysis of nasal defects and nearby donor sites is essential for nasal reconstruction.The use of locoregional flaps leads to consistent and good aesthetic outcomes.
文摘The pectoralis major musculocutaneous (PMMC) flap has been a useful technique for head and neck reconstruction since its first description by Ariyan in 1979. However, techniques in microvascular surgery have since evolved and recently free tissue transfer has played an important role in head and neck reconstruction. Although we use free flaps as the first choice for head and neck reconstruction, similar to many other institutions, some patients at our hospital have undergone reconstruction with PMMC flaps. We retrospectively analyzed the indications and outcomes of this reconstructive technique from our experience with 12 patients. The medical records of all patients who underwent PMMC flaps at Hokkaido Cancer Center from 2001 to 2010 were reviewed. Data concerning diagnosis, main indication, site of reconstruction, previous treatment, and postoperative complications were analyzed. Of the 12 PMMC flap surgeries performed, 3 were carried out as primary reconstructive procedures, whereas 9 were done as “salvage” procedures. Flap-related complications were observed in 6 cases. Partial flap loss developed in 4 patients, although there were no cases of total flap loss. There were 3 recurrent fistulae following reconstruction with PMMC flaps. The preoperative goals of performing PMMC flap surgery were met in 83% of our cases. The authors conclude that while free flap transfer is usually the first choice for head and neck reconstruction, PMMC flaps can produce acceptable results in certain situations.
文摘Objective:To review our experience with infrahyoid myocutaneous flap in reconstruction after oral cancer resection.Methods:Chart reviews were completed for all patients who underwent oral reconstruction with an infrahyoid myocutaneous flap by a single surgeon in the Department of Otolaryngology at Chonburi Cancer Hospital from 2011 to 2017.Characteristics of the patients and postoperative complications were analyzed.Results:Of the 34 patients in the study,10(29.4%)developed partial flap loss and 1(2.9%)developed total flap loss.All cases of partial flap loss resolved with conservative treatment.Apparent cancer involvement of a cervical lymph node was significantly associated with flap failure(odds ratio:5.0,95%CI:1.03e24.28).Conclusions:The infrahyoid myocutaneous flap is a fairly reliable reconstruction method.The flap should be performed with caution in cases with gross lymph node involvement.
文摘Background: Breast cancer is still the most common indication for chest wall irradiation, despite the advances in RTH techniques complications still occur, and the time of its occurrence vary and could take few months to many years. ORN usually manifests with pain, exposed bone, fistulae and pathological fracture and the proper management needs proper debridement and coverage by thick musculocutaneous flaps. Objective: To evaluate different techniques of surgical management of post-irradiation persistent radio-necrotic ulcer & ORN with emphasis on the outcome of each technique. Patients and methods: A retrospective study from 2010 to 2015 reviewed 20 patients subjected to post-mastectomy radiotherapy as a treatment for breast cancer inNCICairo, and Minia oncology center Hospital, Egypt. Cases were biopsied to exclude local recurrence. The age, sex, type of ulcer, dose of radiotherapy received and the management done for these cases were recorded. Results: Only 4 patients responded to conservative treatment in the form of repeated dressings, and 16 patients needed surgical treatment;5 of them were treated with debridement and coverage with split thickness graft with high rate of complications reaching 80%, the other 11 patients were reconstructed with musculocutanoeus flaps, of these 7 patients were reconstructed with LD flaps with 57.14% success rate and minor complications only, the other 4 cases were reconstructed with TRAM flap with 50% success and major loss of the flap in one case that needed salvage by LD flap. Pre-operative comorbidity was found in 6 patients and all of them experienced complications while only 3 of the other 14 who had no comorbidity had postoperative complications. Conclusion: Pedicled flaps provide a good choice for reconstruction and provide chest wall support without the use of synthetic mesh.
文摘<strong>Introduction:</strong> 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. <strong>Patients and method:</strong> This was a prospective and descriptive study of penile skin flap urethroplasty indicated for urethral stenosis between January 2014 and December 2019. <strong>Results:</strong> 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 2<sup>nd</sup> 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. <strong>Conclusion:</strong> 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.
文摘The pectoralis major myocutaneous pedicle flap (PMMF) is still being used by many surgeons and plays an important role in head and neck reconstruction. The purpose of this series was to review our 10 years’ experience with the PMMF in head and neck reconstruction. One hundred and two patients who underwent the PMMF technique were reviewed on the clinical records. Postoperative complications were classified into flap loss, hemorrhage, infection, fistula formation, wound dehiscence and donor site complication. Eighty two patients (80.4%) demonstrated no complication. Six patients among 102 patients (5.9%) demonstrated total or partial skin necroses. Three female patients were completely dissatisfied with the cosmetic appearance after the PMMF. One of them required a reconstructive surgery with the latissimusdorsi flap. Without surgical expertise in plastic surgical field, an ear-nose-throat or an oral surgeon can performed the PMMF technique provided the operator is well aware of serious and frequent complications of this “workhorse” procedure.
