Article Abstract
Background: Capsular contracture is a common complication following implant-based breast reconstruction. Current assessment methods, primarily relying on the subjective Baker grading system, lack objectivity and quantitative data, which hinders large-scale studies and the development of treatment guidelines. To solve these problems, we conducted a study using computed tomography (CT) scans to quantitatively evaluate morphological changes in breast implants associated with capsular contracture.
Methods: We enrolled 94 patients who underwent breast reconstruction using implants and underwent periodic chest CT scans. We categorized them into two groups: Baker grade I or II ( = 72) and Baker grade III or IV ( = 22). We analyzed the CT scans to assess changes in the implant base and projection.
Results: In the Baker grade III or IV groups, it was confirmed that the ratio of projection to base increased after capsular contracture compared with before contracture. On the other hand, there was no significant change in the ratio of projection to base in the Baker grade I or II groups.
Conclusion: This study highlights the potential of CT scans as a reproducible method for evaluating capsular contracture. The ratio of projection to base could serve as a new quantitative index alongside the Baker grades for clinical assessment, treatment planning, and research on capsular contracture. When comparing the ratio of projection to base before and after capsular contracture, if the ratio of projection to base increases by more than 1.233 times, it can be considered Baker grade III or IV.

Background: The insertion of implants and tip plasties has been performed in Asian patients for an attractive and higher nasal profile, which can result in diverse tip deformations such as notching, pinching, alar retraction, incompetent external valve, deviated tip, cephalic rotation, and lateral crus malposition due to inappropriate manipulation of the lower lateral cartilage and/or silicone capsular contracture. This study aimed to investigate the effectiveness and utility of applying lateral crural strut graft (LCSG) as a consistent and appropriate surgical method to correct various nasal tip deformities that occur as complications following rhinoplasty in Asian patients.
Methods: We prospectively studied 37 patients with a minimum follow-up of 12 months among 53 patients who underwent secondary rhinoplasty, including LCSG, between January 2016 and December 2020.
Cells and Shells: Investigating How Breast Implant Shells Negatively Impact Cell Viability In Vitro.

The pathophysiology of breast implant-related adverse outcomes, such as capsular contracture and breast implant-associated anaplastic large cell lymphoma, remains poorly understood. Herein, we explore the direct and indirect effects of smooth and textured implant shells on the viability of cell lines found within the peri-breast implant environment in vitro. The outer silicone shells of Allergan and Mentor breast implants were de-gelled and cut to exactly line the walls of 96-well cell culture plates.

Background: Direct-to-implant (DTI) breast reconstruction has become a widely accepted approach for postmastectomy breast reconstruction. Traditionally, implants were placed in the subpectoral (SP) plane to maximize soft tissue coverage; however, recent advances in surgical technique and implant materials, such as acellular dermal matrices (ADMs) and meshes, have led to a resurgence in the prepectoral (PP) approach. Recent studies have shown conflicting evidence regarding their respective complication profiles and patient-reported outcomes.

: Breast reconstruction following mastectomy is a critical aspect of treatment for many patients, offering both physical and psychological benefits. Traditional methods include autologous tissue flaps and implants, with implant-based techniques being the most prevalent in the Western world. However, complications such as capsular contracture remain a concern.
