OBJECTIVE To introduce the method using the gracilis myocutaneous flaps to repair of vulvar defect after radical vulvectomy. METHODS The gracilis myocutaneous flaps were applied in 4 cases with vulvar carcinoma which located vestibule of vulva and bulk, and the carcinoma was large after radical resection to repair vulvar defect simultaneously. RESULTS The incision of 3 cases was healing by first intention, and 1 case with type II diabetes mellitus was healing by second intention. After followed up 3-6 years, 1 case was recurrent in 2 years after operation, 3 cases were survival without complication. CONCLUSION Vulvar reconstruction with the use of gracilis myocutaneous flaps in radical vulvectomy could markedly decrease the rate of complication.
Objective To discuss and evalue the effects and the advantages of pectoral is major myocutaneous flap in repair of defect caused by resection of tonsillar cancer. Methods The data were retrospectively summarized from 10 patients with recurrent tonsillar cancer after radical radiotherapy from January 1998 to December 2005, including 7 cases of squamouscell carcinoma, 2 cases of undifferentiated carcinoma, and 1 case of adenoid cystic carcinoma. There were 8 males and 2 females, aged 43-68 years with an average of 58 years. All cases were classified as stages III and IV before radiotherapy according to staging standard of oropharyngeal cancer (International Union Against Cancer, 1997). The time of relapse was 6-32 months after radiotherapy. Recurrent tonsil cancer invased tongue base, soft palate, posterior wall of pharyngeal, parapharyngeal space, and palate. Tumor size was from 4 cm × 2 cm to 8 cm × 5 cm. Seven cases were accompanied by lymph node metastasis. After carcinoma were completely resected and defects were reconstructed by pectoral is major myocutaneous flap of 7 cm × 5 cm- 12 cm × 9 cm. The donor sites were sutured directly. Results After operation, pectoral is major myocutaneous flap completely survived in 9 cases. Partial necrosis of pectoral is major myocutaneous flap was found in 1 case; after treatment, the necrotic flap remained small pharyngeal defect. Incision at donor site healed by first intention in 10 cases. All patients showed satisfactory functions of respiratory, voice, and swallowing with no compl ication. Ten patients were followed up 2 years to 5 years and 8 months. The 3-year survival rate was 66.7% (6/9), and the 5-year survival rate was 20.0% (1/5). Conclusion Pectoral is major muscle flap has a high survival rate, which is safe, rel iable, easy-to-operate, and can repair larger defect. Pectoral is major myocutaneous flap is an ideal material in repair of defect caused by resection of recurrent tonsillar carcinoma after radiotherapy.
Objective To observe an early result after the repair of the large upper thoracic wall defect by a combined use of the titaniumnet, reconstruction nickelclad, and latissimus dorsi myocutaneous flap in a patient who underwent a breast sarcomatoid caricinoma resection on the upper thoracic wall. Methods A breast sarcomatoid carcinoma in the upper thoracic wall was removed in 1 56yearold female patient in February 2006. After the tumorectomy, a large thoracic wall defect was left, which was 20cm×15cm in size. The defect was covered by the titanium net, the bilateral stumps of the clavicles were connected by the reconstruction nickelclad, and the soft tissue defect was repaired with the right latissimus dorsi myocutaneous flap(20cm×15cm). Results The patient depended on the breathing machine for 3 days after operation. When the breathing machine was discontinued, the patient developed a severe paradoxical breathing. Two weeks after operation when theblood circulation of the flap was stabilized, the paradoxical breathing disappeared with the help of the chest bandage for fixation of the chest cavity, and the blood supply of the flap was improved. The chest X-ray film showed that the titanium net and the reconstruction nickelclad were well positioned. The patient received chemotherapy 1 month after operation, The follow-up for 3 months revealed that the patient’s local condition and physical condition were good, and ROMof both the shoulders was improved, with AF 90° and ABD 90°. No recurrence ofthe tumor was found. Conclusion A large thoracic wall defect should be repaired with solid materials. The normal anatomic locations of the clavicles should be maintained with fixation by the reconstruction nickelclad for a good function of the shoulders. The latissimus dorsi myocutaneous flap can be properly enlarged.
ObjectiveTo explore the effectiveness of the modified designed bilobed latissimus dorsi myocutaneous flap in chest wall reconstruction of locally advanced breast cancer (LABC) patients.MethodsBetween January 2016 and June 2019, 64 unilateral LABC patients were admitted. All patients were female with an average age of 41.3 years (range, 34-50 years). The disease duration ranged from 6 to 32 months (mean, 12.3 months). The diameter of primary tumor ranged from 4.8 to 14.2 cm (mean, 8.59 cm). The size of chest wall defect ranged from 16 cm×15 cm to 20 cm×20 cm after modified radical mastectomy/radical mastectomy. All defects were reconstructed with the modified designed bilobed latissimus dorsi myocutaneous flaps, including 34 cases with antegrade method and 30 cases with retrograde method. The size of skin paddle ranged from 13 cm×5 cm to 17 cm×6 cm. All the donor sites were closed directly.ResultsIn antegrade group, 2 flaps (5.8%, 2/34) showed partial necrosis; in retrograde group, 6 flaps (20%, 6/30) showed partial necrosis, 5 donor sites (16.7%, 5/30) showed partial necrosis; and all of them healed after dressing treatment. The other flaps survived successfully and incisions in donor sites healed by first intention. There was no significant difference in the incidence of partial necrosis between antegrade and retrograde groups (χ2=2.904, P=0.091). The difference in delayed healing rate of donor site between the two groups was significant (P=0.013). The patients were followed up 15-30 months, with an average of 23.1 months. The appearance and texture of the flaps were satisfactory, and only linear scar left in the donor site. No local recurrence was found in all patients. Four patients died of distant metastasis, including 2 cases of liver metastasis, 1 case of brain metastasis, and 1 case of lung metastasis. The average survival time was 22.6 months (range, 20-28 months).ConclusionThe modified designed bilobed latissimus dorsi myocutaneous flap can repair chest wall defect after LABC surgery. Antegrade design of the flap can ensure the blood supply of the flap and reduce the tension of the donor site, decrease the incidence of complications.
ObjectiveTo explore the effectiveness of pedicled anterolateral thigh myocutaneous flap for full-thickness abdominal wall reconstruction after tumor resection.MethodsBetween September 2010 and December 2017, 18 patients with abdominal wall tumors were collected. There were 11 males and 7 females, with an average age of 45.2 years (range, 29-68 years). Histologic diagnosis included desmoid tumor in 8 cases, sarcomas in 6 cases, malignant teratoma in 2 cases, and colon adenocarcinoma in 2 cases. All abdominal wall defects were full-thickness defects. Peritoneum continuity was reconstructed with mesh; the lateral vastus muscular flaps were used to fill the dead space and rebuild the abdominal wall strength; the abdominal wall soft tissue defects were repaired with pedicled anterolateral thigh flaps. The size of abdominal wall defects ranged from 15 cm×6 cm to 25 cm×22 cm; the size of lateral vastus muscular flap ranged from 10 cm×8 cm to 22 cm×10 cm; the size of anterolateral thigh flap ranged from 14.0 cm×8.0 cm to 21.0 cm×8.5 cm. The bilateral pedicled anterolateral thigh myocutaneous flaps were harvested to repair the extensive abdominal wall defects in 2 cases. All donor sites were sutured directly.ResultsAll wounds healed smoothly and all flaps survived totally. All donor sites healed smoothly. The mean follow-up time was 22.5 months (range, 11-56 months). No tumor recurrence occurred, the abdominal function and appearance were satisfactory, no abdominal hernia was noted. Only linear scar left at the donor sites.ConclusionPedicled anterolateral thigh myocutaneous flap combined with mesh is fit for large full-thickness abdominal defect reconstruction.
OBJECTIVE: To investigate the effectiveness of polypropylene path (Prolene) in hernia prevention following harvesting of rectus abdominis is myocutaneous flap. METHODS: From November 1999 to October 2000, Prolene patches were applied in 26 cases to repair the anterior rectus sheath following harvesting free rectus abdominis myocutaneous flap. Data concerning each case included size of rectus flap, defect of rectus sheath, size of patch used, wound healing and complications. RESULTS: Prolene patch showed good biocompatibility with abdominal tissue. No foreign-body rejection occurred after operation. Seroma developed in 1 case, and was drained bedside without complication. All prolene patches healed well in the body during follow-up. Hernia formation and abdominal bulge were not observed. CONCLUSION: Prolene patch is a satisfactory material for repair of the anterior rectus sheath after harvesting free rectus abdominis myocutaneous flap.
Objective To evaluate the feasibil ity and cl inical significance of the computed tomography angiography (CTA) for the latissimus dorsi muscle (LDM) flap transplantation. Methods From September 2007 to August 2008, 3 cases of soft tissue defects in l imbs were treated with LDM flap transplantation. Three patients included 2 males and 1 female whowere 23 to 42 years old. All of soft tissue defects were caused by trauma. The locations were the forearm in 2 cases and the leg in 1 case. The area of defect was 17 cm × 8 cm-20 cm × 10 cm. All cases received CTA to observe the distribution and anastomosis of thoracodorsal artery. Subsequently, three-dimensional computer reconstruction were carried out to display the stereoscopic structure of the LDM flap and to design the LDM flap before operation. Results The anatomy characteristic of LDM flap can be displayed accurately by the three-dimensional reconstruction model. The distribution of thoracodorsal artery in 3 cases of flaps was in concordance with preoperative design completely. All the flaps were excised successfully, the area of the flap was 19 cm × 10 cm-22 cm × 12 cm. All the transferred flaps survived completely. All cases were followed up from 4 months to 12 months. The color and texture of the flaps were good. Conclusion The three-dimensional reconstructive images can provide visible, stereoscopic and dynamic anatomy for cl inical appl ication of LDM flap. The digitized three-dimensional reconstructive models of LDM flap structures can be appl ied in cl inical training and pre-operative design.
The pectoralis major myocutaneous flap was used to repair laryngopharyngeal and esophageal defect following radical excision of pharyngeal and inferior laryngeal carcinomas in 3 cases. The results were susscessful. The patients were follwedup for 6 months to 3 years. The deglutition functions were all reestablished, the general nutritional conditions were improved, and no recurrence or distant metastasis was observed. The advantages of this operative procedure were discussed.
Twohundrednineteen orofaciomaxillary tumours, 18 benigns and 201 malignancies, were repaired by pectoralis major myocutaneous flaps following their resections. The types of flaps used in the repair were: single island myocutaneous flaps in 201 cases, doubleisland myocutaneous flaps in 16 cases, and myocutan eous skeletal flaps in 2 cases. The results were susscessful in 201 cases and failure in 18. The advantages and indications of using pectoralis major myocutaneous flaps were discussed. The method of design and its relevent surgical thechniques were introduced, and the factors responsible for the success and failure were analyzed. It is noted that the correct and meticulous operative techniques were the main factors leading to operative success.
Objective To investigate the reconstructive methods and effectiveness of modified pedicled anterolateral thigh (ALT) myocutaneous flap for large full-thickness abdominal defect reconstruction. Methods Between January 2016 and June 2018, 5 patients of large full-thickness abdominal defects were reconstructed with modified pedicled ALT myocutaneous flaps. There were 3 males and 2 females with an average age of 43.7 years (range, 32-65 years). Histologic diagnosis included desmoid tumor in 3 cases and sarcoma in 2 cases. The size of abdominal wall defect ranged from 20 cm×12 cm to 23 cm×16 cm. Peritoneum continuity was reconstructed with mesh; lateral vastus muscular flap was used to fill the dead space and rebuild the abdominal wall strength; skin grafting was applied on the muscular flap, the rest abdominal wall soft tissue defects were repaired with pedicled ALT flap. The size of lateral vastus muscular flap ranged from 20 cm×12 cm to 23 cm×16 cm, the size of ALT flap ranged from 20 cm×8 cm to 23 cm×10 cm. The donor site was closed directly. Results All flaps and skin grafts survived totally, and incisions healed by first intention. All patients were followed up 6-36 months (mean, 14.7 months). No tumor recurrence occurred, and abdominal function and appearance were satisfying. No abdominal hernia was noted. Only linear scar left in the donor sites, and the function and appearance were satisfying. Conclusion Modified pedicled ALT myocutaneous flap is efficient for large full-thickness abdominal defect reconstruction, decrease the donor site morbidity, and improve the donor site and recipient site appearance.
