Thermal Preconditioning in Mastectomy Patients With Immediate Breast Reduction

The purpose of this research study is to understand patient experiences and the feasibility of using a breast heat preconditioning device (Plexaa BLOOM43), designed to improve postoperative outcomes when used prior to mastectomy and breast reconstruction.

A Study on Pain After Breast Reconstruction

The purpose of this study is to find out how common persistent postmastectomy pain (PPMP) is among people who have had a mastectomy and breast reconstruction surgery for their breast cancer. The study will also look at how effective regenerative peripheral nerve interface (RPNI) surgery is for reducing pain from neuropathic PPMP after breast reconstruction.

Study on the Cosmetic Outcome and Safety Evaluation of 3D Printed Biodegradable Biological Mesh for One-Stage Breast Reconstruction After Radical Mastectomy

Primary objective of this trial: To evaluate the clinical performance (aesthetic outcome and quality of life) and safety of a 3D-printed biodegradable biological mesh in post-mastectomy immediate breast reconstruction. The study targets adult women undergoing total mastectomy for breast cancer followed by implant-based reconstruction. It aims to determine the utility of the 3D-printed biodegradable mesh in implant-based breast reconstruction, assess its influence on tissue regeneration, postoperative cosmetic result, and complication profile.

Longitudinal Evaluation of Direct Neurotization Technique in Breast Reconstruction With Fully Autologous Components

This clinical trial aims to evaluate whether direct neurotization using fully autologous components during autologous breast reconstruction improves postoperative breast sensation and sensory-related quality of life in women undergoing unilateral mastectomy. Direct neurotization involves coapting the recipient intercostal nerve to an autologous nerve graft placed within the flap to facilitate reinnervation. The study's primary questions are: 1. Does direct neurotization using fully autologous nerve grafts improve cutaneous sensory recovery, as assessed by Semmes-Weinstein monofilament thresholds measured at standardized breast locations? 2. Does neurotization enhance patient-reported sensory outcomes and quality of life, as assessed by the BREAST-Q Sensation Module? As secondary objectives, the study will assess whether biological predictors of nerve regeneration correlate with sensory outcomes. These include: 1. Neuregulin-1 (NRG1) expression in flap tissue biopsy; 2. Cross-sectional area of the recipient nerve fibres; 3. Breast morphometry measured at baseline and follow-up; 4. Intraepidermal nerve fibre density (IENFD) on skin biopsy. Participants will be randomly assigned to receive either: 1. Neurotized autologous breast reconstruction using fully autologous graft components, or 2. Standard (non-neurotized) autologous breast reconstruction. The study will compare these groups to determine whether neurotization accelerates or enhances the return of breast sensation over a 6-month follow-up period, with evaluations at 1 month, 3 months, and 6 months after surgery. Participants will undergo: 1. Autologous breast reconstruction with or without direct neurotization as part of their planned cancer surgery. 2. Sensory testing using Semmes-Weinstein monofilaments at baseline, 1, 3, and 6 months. 3. Completion of BREAST-Q questionnaires evaluating breast sensation, symptoms, and quality of life at each follow-up visit. 3\. Intraoperative tissue sampling for NRG1 analysis and nerve morphometry. 4. Skin biopsy (if applicable) to assess intraepidermal nerve fibre density. 5. Breast morphometry assessment using a breast morphometry measurement software tool. This study seeks to provide high-quality evidence on the effectiveness of direct neurotization using fully autologous components in restoring breast sensation and to explore biological predictors that may influence sensory recovery after autologous breast reconstruction.

Post-market Prospective Clinical Study of Nagor Perle Mammary Implants

Patients can undergo breast implant surgery for multiple reasons; cosmetic and reconstructive being the primary indications. In order to confidently state safety and due to strict regulation on medical devices it is important to maintain a record of safety and performance with all medical implants. This study is designed to collect data on a new generation of smooth mammary implants to assess the long term performance and safety data on this type of gel-filled mammary breast implant. The two main complications of breast implants are capsular contracture and rupture; these complications can take years to develop. The study is designed to evaluate the occurrence of these two primary complication as well as other secondary complications over a period of 10 years. Patient follow up will be carried out pre-operatively and post operatively at 12 months and then 3, 5, 8 and 10 years thereafter. The study will be carried out over 10 years to adequately assess complications which may only occur over the lifetime of the device such as systemic complications
