Objective To explore the value of the application of latissimus dorsi myocutaneous flap in the breast reconstruction. Methods The clinical data of the 36 patients with breast tumor who had undergone breast reconstruction with latissimus dorsi myocutaneous flap from January 2012 to December 2016 were collected retrospectively. The postoperative complications and cosmetic results were analyzed. Results Thirty-six patients with breast tumor who underwent breast reconstruction with latissmus dorsi myocutaneous flap, including 32 patients with immediate breast reconstruction and 4 patients with delayed breast reconstruction respectively. The operative time of the patients who undertwent immediate breast reconstruction was 235–490 min (mean of 325 min), the intraoperative blood loss was 200–260 mL (mean of 220 mL), and the hospitalization time was 18–33 d (mean of 23.6 d). The total operative time of patients who underwent delayed breast reconstruction was 325–550 min (mean of 355 min), the total intraoperative blood loss was 200–250 mL (mean of 220 mL), and the total hospitalization time was 27–45 d (mean of 32.5 d). The cosmetic results was excellent in 22 patients, good in 8 patients, fair in 6 patients, respectively, and fine rate was 83.3% (30/36). There was no flap loss, but donor site seroma occurred in 21 patients, partial necrosis of the surgical margin of back skin occurred in 1 patient, partial necrosis of the nipple and areola skin occurred in 2 patients. All the patients were followed-up for 3–60 months, and the mean follow-up time was 37 months. During the follow-up period, no patient occurred metastasis or recurrence. After undergoing radiotherapy, reconstructive breast volume of 2 patients significantly contracted. None of the patients had significant limb function. Conclusion The breast reconstruction with the latissimus dorsi myocutaneous flap is a simple, easy, and effective surgical procedure.
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 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.
