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.
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 study the methods and results of a combination of forehead skin flap and sternocleidomastoid island myocutaneous flap in the reconstruction of large through-andthrough defect of check. Methods One case of check cancer received ampliative resection and functional neck dissection. The defect area of the skin side was 9 cm×7 cm, of the mucosa side 4.5 cm×3.0 cm.The defect of the mucosa side was repaired with sternocleidomastoid island myocutaneous flap which blood supply was from thyroidea superior artery, occipitalis artery and carotis extera vein; of the skin side with forehead skin flap which blood supply was from temporalis superficialis artery and vein. The size of the sternocleidomastoid island myocutaneous flap was 5 cm×3 cm, of the forehead skin flap10 cm×6 cm. Results Two flaps and the split survived after operation. One-stage healing was achieved. The patient was discharged from hospital 2 weeks afteroperation.The color and the quality were good.The tumor did not recur during follow-up of one year. The patient could take care of herself, and she lived normally in talk and diet. Conclusion A combination of forehead skinflap and sternocleidomastoid island myocutaneous flap is a useful method to repair large through-and-through defect of cheek after cancer dissection. It is easy-to-operate and economical.
The pectoralis major muscle or myocutaneous flap is characterized by its easy dissection and free rotation, as well as abundance of blood supply and tissue mass of the flap, so that it was often used in repairing the wound over the mandibulo-cervico-thoracic area. From 1989 to 1996, 11 cases with long-standing wound of this area were difficult to repair with the traditional method, but were treated with transposition of this type of myocutaneous flap. The myocutaneous flap was applied in 8 case and muscle flap in 3 case. The flap area ranged from 12 cm x 8 cm to 26 cm x 18 cm. All the flaps survived, and excellent results were achieved. The technique and design of the operation were reported in details. It was concluded that the process was easy to perform, and the flap had abundant blood supply and high resistance to infection.
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 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.
Objective To explore the effectiveness of two-stage operation on free latissimus dorsi myocutaneous flap transplantation and skull contour reconstruction in the treatment of head titanium mesh exposure complicated with soft tissue infection. Methods Between January 2015 and December 2021, 13 patients with head titanium mesh exposure complicated with soft tissue infection were admitted. There were 9 males and 4 females with a mean age of 42.9 years (range, 23-64 years). The duration of titanium mesh exposure was 22-609 days (median, 102 days). The wound site located at the frontal part in 3 cases, the parietal part in 1 case, the occipital part in 2 cases, the frontal-parietal part in 1 case, the temporal-parietal part in 4 cases, and the frontotemporal part in 2 cases. The titanium mesh had been taken out in 5 patients before admission, leaving skull defect and shape collapse, with signs of infection. The bacterial culture was positive in 7 cases and negative in 6 cases. The imaging examination revealed that the size of the skull defect ranged from 6 cm×5 cm to 21 cm×17 cm and the scalp defect ranged from 1 cm×1 cm to 15 cm×10 cm. The soft tissue infection did not reach dura in 5 cases, reached dura in 6 cases, and reached frontal sinus in 2 cases. The two-stage surgical protocol was used in all patients. In the first-stage operation, the latissimus dorsi myocutaneous flap was designed to repair the skull and scalp defects after removing the titanium mesh and thorough debridement. The size of muscle flap ranged from 13.5 cm×4.0 cm to 21.0 cm×17.0 cm, and the skin flap ranged from 7.0 cm×4.0 cm to 15.0 cm×10.0 cm. After the flap survived and stabilized, the second-stage operation was performed. The titanium mesh was implanted to reconstruct the skull contour. The size of titanium mesh ranged from 7.0 cm×6.0 cm to 21.5 cm×17.5 cm. The interval between the first- and second-stage operations was 3.7-17.8 months, with an average of 11.4 months. The survival of the skin flap, the appearance of the head, and the presence of re-exposed titanium mesh and infection were observed after operation. Results At the first-stage operation, venous embolism occurred in 1 case, and no obvious abnormality was observed after treatment. All the flaps survived and the incisions healed by first intention. Besides, the incisions of the second-stage operation healed by first intention. All patients were followed up 1-96 months (median, 14 months). During follow-up, no exposure to titanium mesh, infection, or other complications occurred. The appearance satisfaction rate of the patients was 92.31% (11/13). There was no significant difference in the skull contour between the affected side and the healthy side in all patients. Conclusion For the head titanium mesh exposure with soft tissue infection, the application of two-stage operation on free latissimus dorsi myocutaneous flap transplantation and skull contour reconstruction can reduce the risks of implant exposure and infection again by increasing the thickness of the scalp and blood supply, filling the wound cavity, and obtain good effectiveness.
Objective To explore the effectiveness of lobulated pedicled rectus abdominis myocutaneous flap to repair huge chest wall defect. Methods Between June 2021 and June 2022, 14 patients with huge chest wall defects were treated with radical resection of the lesion and lobulated pedicled rectus abdominis myocutaneous flap transplantation for reconstruction of chest wall defects. The patients included 5 males and 9 females with an average age of 44.2 years (range, 32-57 years). The size of skin and soft tissue defect ranged from 20 cm×16 cm to 22 cm×22 cm. The bilateral pedicled rectus abdominis myocutaneous flaps in size of 26 cm×8 cm to 35 cm×14 cm were prepaired and cut into two skin paddles with basically equal area according to the actual defect size of the chest wall. After the lobulated pedicled rectus abdominis myocutaneous flap was transferred to the defect, there were two reshaping methods. The first method was that the skin paddle at the lower position and opposite side was unchanged, and the skin paddle at the effected side was rotated by 90° (7 cases). The second method was that the two skin paddles were rotated 90° respectively (7 cases). The donor site was sutured directly. Results All 14 flaps survived successfully and the wound healed by first intention. The incisions at donor site healed by first intention. All patients were followed up 6-12 months (mean, 8.7 months). The appearance and texture of the flaps were satisfactory. Only linear scar was left at the donor site, and the appearance and activity of the abdominal wall were not affected. No local recurrence was found in all tumor patients, and distant metastasis occurred in 2 breast cancer patients (1 liver metastasis and 1 lung metastasis). Conclusion The lobulated pedicled rectus abdominis myocutaneous flap in repair of huge chest wall defect can ensure the safety of blood supply of the flap to the greatest extent, ensure the effective and full use of the flap tissue, and reduce postoperative complications.
Objective To explore the feasibility and effectiveness of a foldable pedicled latissimus dorsi myocutaneous flap to repair soft tissue defects in the shoulder and back. Methods Between August 2018 and January 2023, the foldable pedicled latissimus dorsi myocutaneous flaps were used to repair soft tissue defects in the shoulder and back of 8 patients. There were 5 males and 3 females with the age ranged from 21 to 56 years (mean, 35.4 years). Wounds were located in the shoulder in 2 cases and in the shoulder and back in 6 cases. The causes of injury were chronic infection of skin and bone exposure in 2 cases, secondary wound after extensive resection of skin and soft tissue tumor in 4 cases, and wound formation caused by traffic accident in 2 cases. Skin defect areas ranged from 14 cm×13 cm to 20 cm×16 cm. The disease duration ranged from 12 days to 1 year (median, 6.6 months). A pedicled latissimus dorsi myocutaneous flap was designed and harvested. The flap was divided into A/B flap and then were folded to repair the wound, with the donor area of the flap being pulled and sutured in one stage. Results All 7 flaps survived, with primary wound healing. One patient suffered from distal flap necrosis and delayed healing was achieved after dressing change. The incisions of all donor sites healed by first intention. All patients were followed up 6 months to 4 years (mean, 24.7 months). The skin flap has a good appearance with no swelling in the pedicle. At last follow-up, 6 patients had no significant difference in bilateral shoulder joint motion, and 2 patients had a slight decrease in abduction range of motion compared with the healthy side. The patients’ daily life were not affected, and linear scar was left in the donor site. Conclusion The foldable pedicled latissimus dorsi myocutaneous flap is an ideal method to repair the soft tissue defect of shoulder and back with simple operation, less damage to the donor site, and quick recovery after operation.
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.
