Detailed Analysis of Three Major Breast Reconstructions Using BREAST-Q Responses From 1001 Patients.

BACKGROUND: Patient-reported outcomes have become as important as mortality and morbidity in the postoperative evaluation of breast reconstruction surgery. The BREAST-Q is one of the most widely used patient-reported outcomes for breast reconstruction. OBJECTIVES: A comparative analysis of the scores on each of the BREAST-Q modules could help analyze different reconstruction methods. However, few studies have utilized BREAST-Q for this purpose. The aim of this study was therefore to compare breast reconstruction methods in terms of BREAST-Q module ratings. METHODS: The authors retrospectively reviewed the data of 1001 patients who had been followed for more than 1 year after breast reconstruction. The 6 BREAST-Q modules were rated on a scale of 0 to 100 and statistically analyzed by multiple regression. In addition, Fisher's exact test was performed after dividing the responses to each question into high- and low-rating groups. RESULTS: Microvascular abdominal flap reconstruction scored significantly better than implant-based reconstruction on all modules, except psychosocial and sexual well-being. In terms of satisfaction with the breast, latissimus dorsi flap reconstruction was superior to implant-based reconstruction. However, in terms of the reconstruction method, there were no differences in patients' willingness to make the same choice again or whether they regretted having surgery. CONCLUSIONS: The results highlight the superiority of autologous breast reconstruction. Reconstruction methods should only be performed after a thorough explanation of their characteristics to achieve results that meet patient expectations. The findings are useful for facilitating patient decision-making in breast reconstruction.

Tertiary Autologous Breast Reconstruction After Implant-Based Reconstruction: Safety and Patient-Related Outcomes.

Silicone breast implants are popularly used for breast reconstruction. As more patients receive long-term silicone breast implants, the number of replacement operations will also increase, and some patients prefer to change from silicone breast implantation to tertiary autologous reconstruction. We evaluated the safety of tertiary reconstruction and assessed patient views regarding the two reconstruction methods. We retrospectively analyzed patient backgrounds, surgical characteristics, and silicone breast implantation retention periods until tertiary reconstruction. We designed an original questionnaire to assess patient opinion regarding silicone breast implantation and tertiary reconstruction. Twenty-three patients (24 breasts) with decisive factors of patient-initiated elective surgery (n = 16), contralateral breast cancer occurrence (n = 5), or late-onset infection (n = 2) underwent tertiary reconstruction. The median time from silicone breast implantation to tertiary reconstruction was significantly shorter in patients with metachronous cancer (47 months) than that in those undergoing elective surgery (92 months). Complications included partial flap loss (n = 1), seroma (n = 6), hematoma (n = 5), and infection (n = 1). Total necrosis did not occur. Twenty-one patients responded to the questionnaire. The satisfaction score was significantly higher for abdominal flaps than for silicone breast implants. When presented with the option to select the initial reconstruction method again, 13 of 21 respondents chose silicone breast implantation. Tertiary reconstruction is beneficial because it reduces clinical symptoms and cosmetic complaints and is recommended as a bilateral reconstruction method, especially for patients with metachronous breast cancer. However, silicone breast implants, which are minimally invasive and associated with shorter hospital stays, were simultaneously found to be sufficiently attractive to patients.

A Novel Risk Model for Predicting Dysphagia after Tongue Reconstruction: A Retrospective Multicenter Study in Japan.

BACKGROUND: There is no consensus on the postoperative outcomes of tongue reconstruction. Therefore, the authors developed a novel risk model for predicting dysphagia after tongue reconstruction. METHODS: This retrospective study was conducted by the Oral Pharyngeal Esophageal Operation and Reconstruction Analytical, or OPERA, group across 31 cancer centers and university hospitals in Japan. A total of 532 patients [390 (73.3%) men and 142 (26.7%) women; median age at surgery, 60 years (range, 15 to 88 years)] who were diagnosed with oral tongue squamous cell carcinoma and underwent tongue reconstruction following glossectomy between 2009 and 2013 were included. Independent risk factors were identified using univariate regression analysis and converted to a binary format for multivariate analysis. An integer value was assigned to each risk factor to calculate a total score capable of quantifying the risk of feeding tube dependence. RESULTS: Overall, 54 patients (10.2%) required a feeding tube at the time of evaluation. Predictive factors for feeding tube dependence were advanced age, lower American Society of Anesthesiologists physical status, low body mass index, lower serum albumin, comorbid hypertension and diabetes, extended tongue defect, resection beyond the tongue, laryngeal suspension, postoperative radiation therapy, and no functional teeth. In multivariate logistic regression analysis, age greater than or equal to 58.5 years, postoperative radiation therapy, wider tongue defect, and body mass index less than 21.27 kg/m 2 earned 6, 4, 3, and 2 points, respectively, for a maximum total score of 15. CONCLUSION: The authors' risk model provides a mathematical tool for estimating the individual risk of postoperative feeding tube dependence before tongue reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

Safety evaluation of immediate breast reconstruction for locally advanced breast cancer in Japanese patients.

BACKGROUND: While breast reconstruction often improves the quality of life of patients with locally advanced breast cancer, there is still no consensus on its safety. This retrospective report aimed to verify the safety of immediate breast reconstruction for locally advanced breast cancer. METHODS: We retrospectively analyzed 500 breast cancer surgeries performed between January 2005 and December 2019 at our hospital, including 120 immediate breast reconstructions. The following five items were analyzed: the patients' choice of reconstruction method, rate of chemotherapy and radiotherapy, surgical margin positivity rate, complications associated with surgery, overall survival rate, and breast cancer-free survival rate. RESULTS: Sixty-three of the 120 patients underwent autologous breast reconstruction. Of those who underwent reconstruction surgery, 95.8% received chemotherapy and 78.3% underwent post-mastectomy radiation therapy. Reconstruction failed in 8 cases with tissue expander and in 1 case with free TRAM flap. Breast reconstruction surgery was not a factor in delaying adjuvant therapy, but complications requiring intervention tended to increase the duration of adjuvant therapy. There was no statistically significant difference in the rate of surgical margin positivity, overall survival rate, or breast cancer-free survival rate. CONCLUSIONS: Although complications associated with reconstructive surgery occurred, appropriate intervention prevented delays in breast cancer treatment, and the complications did not negatively affect the overall or breast cancer-free survival rates. Our study found no evidence to avoid primary breast reconstruction in patients with locally advanced breast cancer.

Breast Splint for Prevention of Nipple-areolar Complex Malposition after Direct-to-implant Breast Reconstruction.

Breast reconstruction with immediate placement of breast implants (direct-to-implant methods) following nipple-sparing mastectomy has increased because of the low burden on the patient and good aesthetic results. However, nipple-areolar complex (NAC) malposition after this surgery remains a common complication that has yet to be entirely resolved. Here, we introduce an approach using Duoactive CGF to prevent postoperative NAC malposition. Immediate postoperative fixation of Duoactive CGF cranially to the NAC of the operated breast was applied for 2-4 weeks. This is referred to as a breast splint. In the study, nine patients who received breast splints and 15 patients who did not were enrolled. The NAC position on the splint-treated breast was compared with that on the healthy side within 6 months after surgery. A case with little visual malposition was defined as having a good outcome, based on the deviation in the cranial direction not exceeding the position of the contralateral NAC. Our preliminary data demonstrated that the rate of good outcomes was significantly higher (P = 0.028) in cases in which a breast splint was used, compared with those that were not treated with a breast splint (7/9, 78.8% versus 4/15, 26.7%). Postoperative application of a breast splint using Duoactive CGF is a simple and useful method to prevent NAC malposition after breast reconstruction, using a direct-to-implant method.

Short- and long-term outcomes of immediate breast reconstruction surgery after neoadjuvant chemotherapy.

PURPOSE: Immediate breast reconstruction (IBR) is a standard option for breast cancer patients, although its utility in patients with advanced breast cancer requiring neoadjuvant chemotherapy (NAC) is debatable. We assessed the short-term complications and long-term prognosis of IBR after NAC. METHODS: We retrospectively analyzed 1135 patients with IBR and/or NAC between 2010 and 2018, 43 of whom underwent IBR after NAC. RESULTS: Twenty-five patients underwent reconstruction with a tissue expander (TE) followed by silicon breast implantation, 5 with a latissimus dorsi muscle transfer flap, and 13 with a deep inferior epigastric perforator flap. Complete surgical resection with a free margin confirmed by a pathological assessment was achieved in all patients. The evaluation of the short-term complications indicated no cases of total flap necrosis, two cases of partial flap necrosis, and one case of wound infection. Only one case required postponement of subsequent therapy due to partial flap necrosis. A long-term evaluation indicated no local recurrence, although distant metastasis was observed in 4 cases, 3 patients died, and TE removal after post-mastectomy radiotherapy (PMRT) was performed in 2 of 11 TE cases. CONCLUSION: IBR may be a viable option in patients with advanced breast cancer who achieve complete surgical resection after NAC.

Safety and Effectiveness of Areola-sparing Mastectomy for Breast Cancer With Intraductal Lesions.

BACKGROUND/AIM: Areola-sparing mastectomy (ASM), a conservative mastectomy with nipple hollowing, can be applied to intraductal breast cancer with a tumour-nipple-areola complex (NAC) distance of ≤2 cm. Here, we evaluated the safety and effectiveness of ASM. PATIENTS AND METHODS: We retrospectively reviewed the surgical outcomes of 61 patients (64 breasts) who underwent ASM between 2016 and 2020. RESULTS: Of the 64 breasts, 33 (51.6%) underwent ASM because the tumour-NAC distance on preoperative magnetic resonance imaging was ≤2 cm. Two patients had positive excisional margins but these were at the posterior areola surface therefore additional resection was possible. Over a median postoperative observation period of 16 months (range=3-52 months), one patient developed chest wall recurrence that was resected and did not recur again. CONCLUSION: For breast cancer with an extensive intraductal component, ASM is a good alternative to nipple-sparing mastectomy because it allows safe resection while maintaining aesthetics.

Evaluation of Temporomandibular Joint Movement After Mandibular Reconstruction.

Mandibular head dislocation and problems with mouth opening may develop after mandibular reconstruction. The authors investigated dislocation of the mandibular head and amount of protrusive sliding (excursion) and their effect on mouth opening. The authors divided 55 mandibular reconstruction patients into 3 groups on the basis of the extent of masticatory muscle and mandibular resection and investigated mandibular head dislocation. On the other hand, the authors focused on mandibular head protrusive excursion as a function of a reconstructed mandible. Protrusive excursion was measured by plain radiography in 29 patients. The extent of mouth opening was measured between the central incisors. Fluoroscopy was performed in 9 patients and the motions of the mandible were analyzed with video-analysis software. Mandibular head dislocation was observed in 15 patients (27.2%) who underwent resection of the mandibular ramus and coronoid process. The extent of mouth opening did not vary significantly among the 3 groups but was lower than that in healthy persons. Mandibular excursion was restricted in patients with conserved temporalis and lateral pterygoid muscles. Protrusive excursion was correlated with the extent of mouth opening. Structural problems involving dislocation of the mandibular head are caused by severing the coronoid process and protrusive excursion disorders are important factors causing mouth opening problems. Physiological sliding and other motions were observed in reconstructed models. The authors believe that when the ramus is resected, there is a greater chance of articular head dislocation. These findings suggest that dislocation of the mandibular head and protrusive excursion disorders arise from imbalances of the remaining masticatory muscles.

Postmastectomy radiation therapy and breast reconstruction with autologous tissue.

Immediate breast reconstruction is an important tool for patients to accept and overcome their breast cancer, as well as for cosmetic reasons. However, its use in patients who require postmastectomy radiation therapy (PMRT) is not yet clear. The purpose of this study was to analyze the effects of PMRT and reconstruction on each other. The time of initiation of PMRT, the prognosis, and the cosmetic results were investigated in patients who underwent immediate reconstruction using autologous tissue. In the case of delayed reconstruction using autologous tissue after PMRT, radiation damage of the chest skin, design of the flap, and cosmetic results were investigated. In 38 patients who underwent immediate reconstruction and PMRT between 2006 and 2015, 20 patients received neoadjuvant chemotherapy, and their mean time before starting PMRT was 9.7 weeks after surgery (range 7-18 weeks). Three patients underwent delayed PMRT (more than 12 weeks) due to partial flap necrosis and wound infection. Of 28 patients (2006-2010), 23 were disease free (stage I: 2/2, stage II: 15/16, stage III: 6/10), one patient (stage III) had distant metastases, and 4 patients died of primary disease (stage II: 1/16, stage III: 3/10). Unacceptable deformation of the reconstructed breast was observed in 4 patients who had partial fat necrosis of the grafted flap or skin necrosis of the mastectomy flap. In 20 patients who underwent delayed reconstruction between 2006 and 2015, 15 (75%) patients underwent replacement of irradiated chest skin with flap skin to reconstruct a soft and natural shape breast. The flap survival rate was 100%, and unacceptable deformation of the reconstructed breast was not seen. In the case of immediate reconstruction using autologous tissue, it is important to graft a flap with a good blood supply to avoid delaying PMRT and achieving a good cosmetic result, because flap necrosis or wound infection delays PMRT and causes scar contracture after PMRT. In the case of delayed reconstruction after PMRT, chest wall skin with radiation damage should be resected and replaced by flap skin.

A new method for inframammary fold recreation using a barbed suture.

BACKGROUND: There are inherent limitations with previously reported inframammary fold (IMF) recreation methods. The IMF is firmly fixed to the chest wall, but not physiologically, and it is difficult to determine the correct IMF position in the supine position and in the absence of an implant. METHODS: With our new IMF reconstruction method (i.e., drawstring method), the IMF is recreated by drawing a barbed suture, penetrating the dermis, along the IMF. The barbed suture is fixed to the costal cartilage at the medial IMF, and the head is drawn and cut externally at the lateral IMF. The IMF level and depth can be finely adjusted by the tension, in a seated position after implant insertion. Furthermore, the approach can be from a small incision, and a smooth IMF curve is reconstructed. RESULTS: Our drawstring method was performed in 102 patients who underwent reconstruction using a breast implant (n = 95) or flap (n = 7). The mean patient age was 52.0 years (range 33-77 years) and the follow-up period was 12 months (range 3-18 months). Suture or implant infection or exposure did not occur. Suture slack occurred in ten patients with implant-based reconstruction; their IMF became shallow. Insufficient skin expansion (P < 0.005) and strong traction of the barbed suture from the caudal side (P < 0.05) were related to IMF slack. The total revision rate was 2.9 %. CONCLUSIONS: With sufficient skin expansion, the drawstring method using a barbed suture enables smooth and symmetrical IMF reconstruction.

Large chest wall reconstruction using a pedicled osteomuscle composite flap: report of a case.

A 67-year-old man with diabetes mellitus and chronic renal failure underwent resection of a grade 1 chondrosarcoma. We performed chest wall reconstruction of the massive defect, using a pedicled osteomuscle composite flap comprising the 6th, 8th, and 10th ribs, and the latissimus dorsi and serratus anterior muscles. This flap is ready to mobilize as a pedicled graft to cover a large chest wall defect; it is strong enough to buttress the chest cage without the need for artificial materials, and it is associated with a lower risk of infection than prosthetic materials.
