Breast Reduction with Implants or Augmentation Reduction: Patient-Reported Outcomes from a Single-Centre Retrospective Cohort Analysis

Background and Objectives: The correction of breast hypertrophy and ptosis with implant placement has always posed a challenge for plastic surgeons. Various methods have been devised, yielding conflicting results. The purpose of this study is to describe our surgical technique of breast reduction with silicone implants, present the safety profile of the procedure, and report patient-reported outcomes. Materials and Methods: A retrospective review was performed on our case series of cosmetic breast surgery performed by the senior author between October 2020 and November 2023. Only patients who had over 300 g of breast tissue removed were included. The surgery and demographic characteristics were recorded. Patients were asked to complete a questionnaire about satisfaction with their breasts pre-operatively and after the surgery. Results: Over 745 cases were performed, and 25 were included in the analysis. In total, 78.3% of the patients presented with a Grade 3 ptosis. The mean implant size was 352.39 cc (range 300-455 cc). The breast tissue removed ranged from 312 to 657 g. The mean follow-up was 14.17 months. Only one case required revision surgery after developing capsular contracture and a waterfall deformity. Patients reported a statistically significant improvement across all domains of the questionnaire (p < 0.001). Conclusions: Breast reduction plus implants is a safe and effective alternative for patients with large ptotic breasts who wish to attain a full upper pole. It carries a similar risk profile to augmentation mastopexy and maintains its functional benefits in alleviating back, neck, and shoulder pain.

A comparative study between deep inferior epigastric artery perforator flap breast reconstruction and DIEP flap breast reconstruction coupled with vascularized lymph node transfer: Improving the quality of life of patients with breast cancer related lymphedema without affecting donor site outcomes

BACKGROUND

Despite simultaneous microvascular breast reconstruction (MBR) and vascularized lymph node transfer (VLNT) gaining wide popularity as a potential treatment for breast cancer related lymphedema (BCRL), there is a lack of evidence supporting the procedure. There are few reports in the literature, and no study has compared simple deep inferior epigastric artery perforator (DIEP) to simultaneous DIEP flap and VLNT.

PATIENTS AND METHODS

A retrospective analysis of our series of DIEP flaps was conducted. Patients presenting with BCRL who had delayed MBR and simultaneous VLNT were selected. Thirty-two patients were included and compared with a control group of delayed MBR with DIEP flap alone. Clinical evaluation, circumference reduction rate, and LYMQOL questionnaire were used to compare preoperative and postoperative findings in the study group. A digital version of BREAST Q questionnaire was administered to all patients.

RESULTS

Thirty-two patients were enrolled in the study group, with a mean follow-up of 42.5 ± 25.7 months and mean age of 54.1 ± 7.8 years. The mean circumference reduction rate was 46.1 ± 52.3, 39 ± 42.3, 47.5 ± 53.5, 39.2 ± 52.4, 33.6 ± 50.1 at the deltoid insertion, above the elbow, below the elbow, at the mid-forearm and wrist respectively. Postoperative LYMQOL scores significantly improved (function 1.21, appearance 1.15, symptoms 1.34, mood 1.33, overall QOLscore 8.6) from preoperative baseline (p < .001). There was no significant difference in term of outcomes and complications rate of the donor site between the study and control groups.

CONCLUSIONS

Simultaneous DIEPandVLNT improves the HRQOL of patients with lymphedema. Coupling VLNT with abdominal flap does not increase the morbidity of donor site.

Partition of Pectoralis Major Musculocutaneous Flap as a Salvage Procedure for Simultaneous Coverage of the Exposed Carotid Artery and Reconstruction of Cervical Esophagus

BACKGROUND

In advanced pharyngoesophageal cancer patients, a critical event is represented by the failure of primary reconstruction with exposure of the carotid artery and partial or total defect of the cervical esophagus. For these high-risk patients, a partitioned pectoralis major musculocutaneous (PMMC) flap can prevent carotid blowout and provide skin for simultaneous esophageal reconstruction.

METHODS

Twenty-six patients needing pharyngoesophageal reconstruction together with coverage of carotid artery exposure were included in this retrospective case series. The patients were treated with a partitioned PMMC flap, based on the branching pattern of the pectoral branch of the thoracoacromial artery and the perforators of the pectoralis major muscle, to simultaneously reconstruct the defect and provide coverage for the carotid artery.

RESULTS

In 25 patients, the partitioned PMMC flap reconstructions resulted in complete wound healing without occurrence of carotid blowout syndrome or fistula formation. Minor complications as partial flap necrosis (7.7%) and strictures formation (7.7%) were recorded but did not compromise reconstruction. Twenty-two patients were able to adopt a semisolid diet, and 4 had recurrence of cancer.

CONCLUSIONS

The partitioned PMMC flap reconstruction represents a useful salvage solution to simultaneously restore the continuity of the alimentary tract and provide reliable coverage for the exposed carotid artery.

Muscle-Sparing Skin-Reducing Breast Reconstruction with Pre-Pectoral Implants in Breast Cancer Patients: Long-Term Assessment of Patients' Satisfaction and Quality of Life

INTRODUCTION

Breast cancer is the most frequently diagnosed tumor in women; globally, it accounts 23% of all cancer deaths. Breast reconstruction after oncologic surgery has become crucial to enhance patients' quality of life and alleviate the psychological distress related to the disease. The aim of this study was to assess quality of life and esthetic satisfaction of breast cancer patients undergoing muscle-sparing skin-reducing breast reconstruction (MS-SR) with pre-pectoral implants.

METHODS

Sixty-three patients who met definite oncological and reconstructive criteria were enrolled in the study. Specific questionnaires (EORTC QLQ-C30, QLQ-BR23) were administered preoperatively, 1, and 12 months after MS-SR breast reconstruction to evaluate patients' QoL. Satisfaction with procedure and related Quality of Life were assessed through BREAST-Q questionnaire preoperatively and 12 months after surgery.

RESULTS

Sixty-three breast cancer patients underwent MS-SR. Seventy-eight procedures were carried out; in 15 patients a bilateral reconstruction was performed. One month after surgery, both EORTC QLQ-C30 and QLQ-BR23 average scores demonstrated a slight drop since preoperative values, but a significant improvement in QoL was documented 12 months after BR (p < 0.05). BREAST-Q test showed significant psychophysical and esthetic satisfaction 12 months postoperatively.

CONCLUSIONS

Muscle-sparing skin-reducing breast reconstruction is an established and reliable technique. EORTC QLQ-C30, QLQ-BR23 and BREAST-Q scores showed an improvement of patients' QoL and esthetic satisfaction. Reduction of pain and other surgery-related symptoms are cornerstones of patient well-being. Both physicians and patients should build a thorough awareness of the silver lining of muscle-sparing skin-reducing breast reconstruction based on the high safety profile and highly satisfactory patient-reported results.

Anatomical Study and Clinical Application of Ulnar Artery Proximal Perforator Flaps

BACKGROUND

 The purpose of this study is to document the vascular anatomy of the free ulnar artery proximal perforator flap and to highlight the possibility of harvesting it based on the perforators originating from the posterior ulnar recurrent artery (PURA), to spare both the main axis of vascular supply to the hand. In addition, we present a case series of five patients treated for soft tissue defects of the hand with free ulnar artery proximal perforator flaps.

METHODS

 Ten specimens of anterior forearm were dissected in this study to register number and characteristics of ulnar perforators. The dissection was focused on the perforators originating from the larger branch of the ulnar artery, the PURA, at the proximal third of anteromedial forearm. The anatomical dissections were evaluated in relationship with clinical dissections performed during flap harvesting in five patients.

RESULTS

 In three of the specimens dissected, the proximal perforator originated from the PURA, and in the other seven specimens, it originated directly from the ulnar artery. Five cases of reconstruction of the hand were performed with success using the free ulnar artery proximal perforator flap, and in two cases, the perforator from the PURA was found and it was possible to raise the flap based on this branch of the ulnar artery.

CONCLUSION

 The free ulnar artery proximal perforator flap can be harvested in two different manners for the same skin island of the forearm. When possible, harvesting it form the PURA allows lengthening of the pedicle. In our experience, this flap presents many advantages such as thinness and hairlessness; it allows preservation of the ulnar neurovascular bundle with an acceptable donor site morbidity.

A prospective study on combined lymphedema surgery: Gastroepiploic vascularized lymph nodes transfer and lymphaticovenous anastomosis followed by suction lipectomy

BACKGROUND

There is no consensus on the appropriate treatment of lymphedema. Proposed techniques include lymphaticovenous anastomosis (LVA), vascularized lymph nodes transfer (VLNT), and suction lipectomy (SL). The benefit of combined procedures has also been postulated. In this prospective study, a combined protocol is proposed as an alternative to single-procedure strategies.

METHODS

Between January 2016 and October 2018, we enrolled patients with secondary lymphedema of lower limbs, stage II-III according to the International Society of Lymphology, progressive swelling and skin tonicity >60. Thirty-seven consecutive patients were dichotomized into group I, undergoing VLNT, and group II undergoing VLNT and LVA. Gastroepiploic lymphnode flap was harvested through laparoscopy, and in the same operation, LVAs were performed in group II on the basis of indocyanine green lymphography and patent blue findings. Two weeks later, SL was performed in all the patients. Patients were prospectively evaluated through clinical examination, circumference measurement, and skin tonicity.

RESULTS

The average follow-up was 2 ± 0.8 years. The first consecutive 21 patients were treated with VLNT followed by SL. The next 16 patients underwent combined VLNT and LVA, followed by SL. A mean of 2.4 LVAs were performed. A significant difference in the postoperative circumference measurements was found overall (p < .05): 52.6 ± 18.9 above the knee, 42.9 ± 25 below the knee, 36.2 ± 37 at foot. The postoperative tonicity dropped by 12.7 ± 6.3% (p < .05). The episodes of cellulitis significantly decreased to 0.1 ± 0.3 (p < .05).

CONCLUSIONS

LVA, VLNT, and SL can be integrated together in a combined approach, in synergy to enhance the outcomes.

The versatility of the thoracodorsal artery based composite flaps with vascularized rib and a systematic review of the literature

Pedicled and free composite flaps derived from the thoracodorsal artery system, including the latissimus dorsi-rib (LD-R) and the serratus anterior-rib (SA-R) osteo-muscular or osteo-myocutaneous flaps, are potential options to address head and neck, thorax, upper and lower extremity bone, and soft tissue defects' reconstruction. We aimed to report our series of LD/SA-R composite pedicled and free flaps, evaluating outcomes and complications, and to systematically identify all literature reporting results following LD/SA-rib reconstructions.

Outcomes following head neck free flap reconstruction requiring interposition vein graft or vascular bridge flap

BACKGROUND

Interposition vein grafts (IVG) and vascular bridge flaps (VBF) have been exploited as vascular conduit in challenging head and neck reconstructions.

METHODS

A retrospective review was conducted on 6025 flaps. The effect of patients' characteristics and length of IVG on flap compromise and loss were analyzed. Comparison between IVG and VBF was performed.

RESULTS

The flap compromise and loss rates for the overall group were 8.2% and 3.2%, respectively. An IVG was used in 309 free flaps. The average length of the vein grafts was 6.9 ± 4.2 cm. An unplanned return to the operation room occurred in 32 cases (10.4%) and failure of the flap in 12 patients (3.9%). Binary logistic regression found a significant association between flap compromise and loss rates and length of IVG, hypertension, prior radiation, and neck dissection. In the multiple regression model, length of IVG and prior radiation significantly influenced the outcomes. Thirty-nine patients underwent reconstruction with a long IVG (>10 cm). Twenty-six patients underwent surgical reconstruction with radial forearm flap as a VBF. The rate of flap compromise was higher in the group with a long IVG (P = .01).

CONCLUSIONS

In head and neck free flap reconstruction, the length of IVGs and history of radiotherapy are associated with flap compromise and loss. In case of long distance between the pedicle and the recipient site, the use of a VBF bridge should be considered as a safe alternative.

Modified single pedicle reverse adipofascial flap for fingertip reconstruction

BACKGROUND

Homodigital adipofascial flap is a well-established method for treating a distal fingertip defect; nonetheless, its use has some limitations. Reconstruction of fingertip injuries, with radial or ulnar tissue loss, may lead to some difficulties in providing an adequate bone coverage. The standard bipedicled technique did not allow the flap to cover the bone exposure without excessive tension. In our series, the reverse adipofascial flap had a single pedicle. The modified technique, because of its improved degree of rotation, granted the flap to reach either radial or ulnar tissue losses.

PATIENTS AND METHODS

We treated 15 fingertip amputations distal to the lunula (9 Allen's type II and 6 type III), the mean size of defects was 2.7 cm² (range, 1.8-3.2 cm² ), the mean age of patients was 44 years (range, 22-63 years). Quick Disabilities of the Arm, Shoulder, and Hand score and Visual Analogue Scale were evaluated along with a 2-point discrimination test; the aesthetic satisfaction of the patients was estimated subjectively using a 5-point Likert scale.

RESULTS

Mean flap size was 3.6 cm² (range, 2.5-4.2 cm² ), primary flap survival was observed in 14 out of 15 cases, partial flap necrosis was observed in 1 case, the nail grew in all fingers in about 6 months. Mean proximal and distal interphalangeal joint motion was 89° (range, 80°-100°) and 71° (range, 65°-80°), respectively. No complications were observed at the donor site. The median static 2-point discrimination was 4.5 mm (range, 3-8 mm), the mean quick DASH score was 2.6 (range, 0-9.1). All patients returned to work within a mean of 4.4 weeks (range, 4-5 weeks). The follow-up was 12 months.

CONCLUSIONS

Single pedicle reverse adipofascial flap is an effective technique. This modified procedure allows a wider degree of flap rotation; it represents the ultimate arrow in our bow to address some particular defect geometry.

Clinical significance of the buccal fat pad: how to determine the correct surgical indications based on preoperative analysis

Background: Despite the multitude of clinical and aesthetic uses, the correct surgical indications for buccal fat pad (BFP) removal have yet to be fully elucidated. Although the procedure is widely performed and promoted for aesthetic purpose, literature lacks of studies accounting for a proper evaluation of patients undergoing BFP removal.Methods: Between 2012 and 2016 patients seeking an improvement of the malar contour by reduction of the submalar prominence have been visited at the Department of Plastic Surgery of the Institution. A preoperative MRI was requested in order to correctly identify the volume of the BFP and the presence of a masseter muscle (MM) hypertrophy.Results: According to clinical examination and the results of the preoperative imaging, patients were offered different treatment options: patients with BFP hypertrophy underwent BFP removal through an itraoral approach; patients with MM hypertrophy received injection of 50 UI of botulinum toxin (BTX). No complications were observed in the postoperative period and all patients were satisfied with the results.Conclusions: According to the experience, midface contouring procedures should take account of both surgeons’ experience, patients’ expectations and anatomical evaluation. As such, there is no given approach suitable for all cases. Suggested visual criteria, clinical examination and imaging analysis are useful in establishing patient’s condition and determining the appropriate methods of treatment to enhance the facial profile.

One-stage muscle-sparing breast reconstruction in elderly patients: A new tool for retaining excellent quality of life

More than 50% of breast cancer care occurs in elderly but women aged 65 and over generally have lower breast reconstruction (BR) rates. In medical literature, few papers focused on BR in elderly patients and usually the reported techniques are multisteps such as expander-implant reconstruction, local, and free flaps. We present a one-stage reconstruction technique employed in elderly patients: muscle-sparing immediate BR with subcutaneous implant and Braxon acellular dermal matrix. We prove the feasibility and safety of the technique and believe that this new procedure could represent a potential benefit in elderly BR.

Clinical, histological, and ultrasound follow-up of breast reconstruction with one-stage muscle-sparing "wrap" technique: A single-center experience

BACKGROUND

Prepectoral implant placement and complete coverage with porcine acellular matrix after mastectomy is a new concept in breast surgery presented in few cases in the literature. This paper aimed to present our single-center experience in one-stage breast reconstruction muscle-sparing "wrap" technique by evaluating clinical and aesthetic outcomes, ultrasound and histological examination, and patient quality of life.

METHODS

From January 2014 to January 2017, 52 patients (40 unilateral, 12 bilateral) underwent one-stage muscle-sparing breast reconstructions with Braxon^® acellular dermal matrix and implant. In 3 patients, a surgical biopsy and histological examination with immunohistochemical analysis of the periprosthetic tissue were performed. All patients underwent breast ultrasound examination, and the occurrence of capsular contracture was assessed through the Baker classification and by measuring the mammary compliance scores with the Antoon Paar Mammary compliance system. Breast appearance was evaluated using a visual analogue scale (VAS) and in terms of quality of life using the EOCRT QLQ C-30 and QLQ BR-23 questionnaires.

RESULTS

Early and late postoperative complications are reported. Histological and ultrasound evaluation showed a complete integration of the matrix. According to the VAS scale, the EOCRT QLQ C-30, and QLQ BR-23, patients' satisfaction resulted in a high score in terms of quality of life and aesthetic outcomes.

CONCLUSION

The results of this new surgical technique in selected cases are promising in terms of effectiveness and low rate of postoperative complications, but further long-terms evaluations are required.

Adipose-derived stem cell therapies for bone regeneration

INTRODUCTION

Cell-based therapies exploit the heterogeneous and self-sufficient biological environment of stem cells to restore, maintain and improve tissue functions. Adipose-derived stem cells (ASCs) are, to this aim, promising cell types thanks to advantageous isolation procedures, growth kinetics, plasticity and trophic properties. Specifically, bone regeneration represents a suitable, though often challenging, target setting to test and apply ASC-based therapeutic strategies. Areas covered: ASCs are extremely plastic and secrete bioactive peptides that mediate paracrine functions, mediating their trophic actions in vivo. Numerous preclinical studies demonstrated that ASCs improve bone healing. Clinical trials are ongoing to validate the clinical feasibility of these approaches. This review is intended to define the state-of-the-art on ASCs, encompassing the biological features that make them suitable for bone regenerative strategies, and to provide an update on existing preclinical and clinical applications. Expert opinion: ASCs offer numerous advantages over other stem cells in terms of feasibility of clinical translation. Data obtained from in vivo experimentation are encouraging, and clinical trials are ongoing. More robust validations are thus expected to be achieved during the next few years, and will likely pave the way to optimized patient-tailored treatments for bone regeneration.

Lipoaspirate fluid proteome: A preliminary investigation by LC-MS top-down/bottom-up integrated platform of a high potential biofluid in regenerative medicine

The lipoaspirate fluid (LAF) is emerging as a potentially valuable source in regenerative medicine. In particular, our group recently demonstrated that it is able to exert osteoinductive properties in vitro. This original observation stimulated the investigation of the proteomic component of LAF, by means of LC-ESI-LTQ-Orbitrap-MS top-down/bottom-up integrated approach, which represents the object of the present study. Top-down analyses required the optimization of sample pretreatment procedures to enable the correct investigation of the intact proteome. Bottom-up analyses have been directly applied to untreated samples after monodimensional SDS-PAGE separation. The analysis of the acid-soluble fraction of LAF by top-down approach allowed demonstrating the presence of albumin and hemoglobin fragments (i.e. VV- and LVV-hemorphin-7), thymosins β4 and β10 peptides, ubiquitin and acyl-CoA binding protein; adipogenesis regulatory factor, perilipin-1 fragments, and S100A6, along with their PTMs. Part of the bottom-up proteomic profile was reproducibly found in both tested samples. The bottom-up approach allowed demonstrating the presence of proteins, listed among the components of adipose tissue and/or comprised within the ASCs intracellular content and secreted proteome. Our data provide a first glance on the LAF molecular profile, which is consistent with its tissue environment. LAF appeared to contain bioactive proteins, peptides and paracrine factors, suggesting its potential translational exploitation.

Qualitative and quantitative differences of adipose-derived stromal cells from superficial and deep subcutaneous lipoaspirates: a matter of fat

BACKGROUND AIMS

Subcutaneous fat represents a valuable reservoir of adipose-derived stem cells (ASCs) in the stromal vascular fraction (SVF), widely exploited in regenerative medicine applications, being easily harvested through lipoaspiration. The lack of standardized procedures for autologous fat grafting guided research efforts aimed at identifying possible differences related to the harvesting site, which may affect cell isolation yield, cell growth properties and clinical outcomes. Subcutaneous fat features a complex architecture: the superficial fascia separates superficial adipose tissue (SAT) from deep layer tissue (DAT). We aimed to unravel the differences between SAT and DAT, considering morphological structure, SVF composition, and ASC properties.

METHODS

SAT and DAT were collected from female donors and comparatively analyzed to evaluate cellular yield and viability, morphology, immunophenotype and molecular profile. ASCs were isolated in primary culture and used for in vitro differentiation assays. SAT and DAT from cadaver donors were also analyzed through histology and immunohistochemistry to assess morphology and cell localization within the hypoderm.

RESULTS

Liposuctioned SAT contained a higher stromal tissue compound, along with a higher proportion of CD105-positive cells, compared with DAT from the same harvesting site. Also, cells isolated from SAT displayed increased multipotency and stemness features. All differences were mainly evidenced in specimens harvested from the abdominal region. According to our results, SAT features overall increased stem properties.

CONCLUSIONS

Given that subcutaneous adipose tissue is currently exploited as the gold standard source for high-yield isolation of adult stem cells, these results may provide precious hints toward the definition of standardized protocols for microharvesting.
