Objective
To introduce the myocutaneous flap in blepharoplasty and summarize its clinical efficacy.
Methods
Between January 2013 and March 2016, 1 560 patients underwent blepharoplasty with myocutaneous flap. Of them, 158 patients were followed up over 6 months and included in the study. There were 18 males and 140 females with the average age of 23.4 years (range, 18-35 years). The unilateral side was involved in 13 cases and bilateral sides in 145 cases. The patients had narrow double eyelid, shallow double eyelid, single eyelid, bloated upper eyelid, and upper eyelid skin relaxation. During operation, the tissue between the orbicular muscle of eye and the tarsus was trimmed layer by layer; the orbicularis oculi muscle, capillary network, and the front fascia of tarsus were retained, and the full-thickness skin, muscle, and the front fascia of tarsus were sutured by anatomical apposition.
Results
Incision healed at stage I. All patients were followed up 6 months to 2 years (mean, 8.3 months). During follow-up period, shallow or extinctive double-eyelid line was observed in 9 cases (12 eyes), and satisfactory results were achieved after trimming front fascia of tarsus and suturing. Good clinical results were obtained in the other patients, who had natural and coherent double eyelid without obvious scar or depression at resection margin.
Conclusion
Myocutaneous flap for blepharoplasty has many advantages of fast recovery, little wound, light swelling, permanent effects, and good appearance.
Objective To introduce the experience of the cl inical appl ication of vertical trapezius myocutaneous flap in repairing soft tissue defects after head and neck tumor resection. Methods Between June 2008 and February 2010, 12 cases of soft tissue defect caused by head and neck tumor resection were repaired with vertical trapezius myocutaneous flap.There were 9 males and 3 females with an age range from 32 to 76 years (median, 54 years). Twelve cases including 2 cases of basal cell carcinoma of orbital skin, 2 cases of squamous cell carcinoma of the parotid gland, 2 cases of submandibular gland mal ignant mixed tumor, 2 cases of metastatic lymph nodes of nasopharyngea carcinoma after radiotherapy, 1 case of squamous cell carcinoma of tongue, and 3 cases of squamous cell carcinoma of occipital skin, and all were classified as TNM stages T3 or T4. The area of soft tissue defect ranged from 13 cm × 6 cm to 25 cm × 13 cm. The vertical trapezius myocutaneous flap ranged from 14 cm × 7 cm to 26 cm × 14 cm and was transfered to repair defect tissue in the homolateral wounds after tumor resection and neck dissection homochronously. The donor sites were sutured directly. Results All incisions healed primarily without infection. Eleven flaps survived except 1 flap with edge necrosis, which was cured after dressing change. Subcutaneous hematocele and effusion occurred in 2 cases on the back after tube was removed at 7 days postoperatively, and they were cured by sucted and pressured dressing. Eleven patients were followed up 1-3 years (mean, 2 years). Nine cases had no tumor recurrence and the flaps had statisfactory appearance; the abduction function of shoulder joint were normal. One case of orbit basal cell carcinoma occurred 3 months after operation and 1 case of nasopharyngeal carcinoma died of brain metastasis 12 months after operation. Conclusion It is an easy and simple therapy to repair head and neck soft tissue defect using the vertical trapezius myocutaneous flap, which can meet the needs of repairing tissue defect of head and neck.
ObjectiveTo investigate the effectiveness of free transverse gracilis myocutaneous flap for soft tissue defects of foot and ankle. Methods Between January 2017 and December 2020, 16 cases (17 feet) of soft tissue defects of foot and ankle were repaired with free transverse gracilis myocutaneous flaps. There were 10 males and 6 females, with an average age of 38 years (range, 23-60 years). There were 9 cases of left foot, 6 cases of right foot, and 1 case of bilateral feet. The causes of soft tissue defect were traffic accident injury in 3 cases, heavy object smash injury in 4 cases, machine injury in 3 cases, infection in 4 cases, electrical burn in 1 case, and synovial sarcoma after operation in 1 case. The wounds located at the distal plantar in 2 cases (2 feet), the heel and ankle in 6 cases (6 feet), the dorsum of the foot in 7 cases (8 feet), and the first metatarsophalangeal joint to the medial malleolus in 1 case (1 foot). The size of wounds ranged from 6 cm×5 cm to 18 cm×7 cm. The size of flap ranged from 11 cm×6 cm to 21 cm×9 cm. The donor site was sutured directly. Results After operation, 1 case (1 foot) of flap vascular crisis, 1 case (1 foot) of partial necrosis of the flap, and 1 case of partial dehiscence of the incision at donor site occurred, all of which healed after symptomatic treatment. The other flaps survived, and the incisions at donor and recipient sites healed by first intention. All patients were followed up 12-36 months (mean, 24 months). Except for 1 case (1 foot) of swollen flap, which underwent two-stage trimming, the other flaps had good shape and texture. All the flaps had a protective feeling. At last follow-up, Kofoed scores of foot and ankle function ranged from 73 to 98 (mean, 89.7); 13 cases were excellent, 2 cases were good, and 1 case was poor, with an excellent and good rate of 93.8%. Linear scar was formed at the donor site without adverse effect on lower limb function. ConclusionThe free transverse gracilis myocutaneous flap is an effective flap for repairing large soft tissue defects of foot and ankle due to its advantages of large excisable area, less variation of vascular anatomy, and concealment of donor site.
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.
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 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.
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.
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.
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.
The paper reported the clinical experience of using pectoralis major myocutaneous flap for the immediate repair of massive defects from excising the oral and maxillofacial malignant tumours in 21 cases from 1985 to 1993. The valuation, design, preparation, technique of transfer of the flap and the prevention of flap from necrosis were discussed. It was suggested that the pectoralis major myocutaneous flap was worth using for the immediate repair of massive defects around oral and maxillofacial regions.
