Background: Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a type of non-Hodgkin lymphoma first linked with breast implants in 2011. The correlation between BIA-ALCL and textured devices has led to increased use of smooth devices. However, much of the data surrounding smooth and textured devices investigates breast implants specifically and not tissue expanders.
Objectives: We performed a systematic review and a meta-analysis to compare surgical outcomes for smooth tissue expanders (STEs) and textured tissue expanders (TTEs).
Methods: A search was performed on PubMed, including articles from 2016 to 2023 (n = 419). Studies comparing TTEs and STEs and reported complications were included. A random-effects model was utilized for meta-analysis.
Results: A total of 5 articles met inclusion criteria, representing 1709 patients in the STE cohort and 1716 patients in the TTE cohort. The mean duration of tissue expansion with STEs was 221.25 days, while TTEs had a mean time of tissue expansion of 220.43 days.Our meta-analysis found no differences in all surgical outcomes except for explantation risk. STE use was associated with increased odds of explantation by over 50% compared to TTE use (odds ratio = 1.53; 95% CI = 1.15 to 2.02; P = .003).
Conclusions: Overall, STEs and TTEs had similar complication profiles. However, STEs had 1.5 times higher odds of explantation. The incidence of BIA-ALCL is low, and only a single case of BIA-ALCL has been reported with TTEs. This indicates that TTEs are safe and may lower the risk of early complications requiring explantation. Further studies are warranted to further define the relationship between tissue expanders and BIA-ALCL.

Background: Postmastectomy radiation therapy (PMRT) can influence the outcome of implant-based breast reconstruction (IBBR). This study aims to investigate the complications and patient-reported outcomes (PROs) following PMRT between direct-to-implant (DTI) and tissue expander-to-implant (TEI) reconstruction.
Methods: The retrospective study included breast cancer patients undergoing IBBR and PMRT.

Background: Adequate horizontal and vertical bone volume is an ideal prerequisite to achieving good primary stability, osseointegration, and long-term survival of an implant. Several techniques are available to achieve adequate bone volume for implant placement. Among the various non-subtractive methods, ridge expansion with motorized bone expanders is a commonly used method to expand bone volume in the anterior maxilla.

Background: Poorly controlled acute breast surgery postoperative pain is associated with delayed recovery, increased morbidity, impaired quality of life, and prolonged opioid use during and after hospitalization. Recently, ultrasound-guided pectoralis nerve (PECS) I block and serratus anterior plane (SAP) block, together or individually, have emerged as a potential method to relieve pain, decrease opioid requirements, and improve patient outcomes.
Objective: The aim of this study was to assess if the addition of a PECS I/SAP block in patients undergoing bilateral mastectomies provides more effective perioperative analgesia compared to standard analgesia.

Hypertrophic scarring (HTS) is an abnormal process of wound healing that results in excessive scar tissue formation. Over the past decade, we have demonstrated that mechanotransduction-the conversion of mechanical stimuli into cellular responses-drives excessive fibrotic scar healing. A mouse model to assess human-like hypertrophic scarring would be an essential tool for examining various therapeutics and their ability to reduce scarring and improve healing.

Infrared (IR) emitters have drawn considerable attention for applications in deep-tissue imaging, optical communication, and thermal sensing. While III-V and II-VI semiconductors are traditionally used in these emitters, their reliance on complex epitaxial growth to overcome lattice mismatch and thermal expansion challenges leads to intricate device structures and limits their integrability. In contrast, 2D materials provide a more flexible solution, offering diverse optical bandgaps and the ability to be vertically restacked in arbitrary crystal orientations to form complex van der Waals (vdW) heterostructures, which can be further integrated onto diverse device platforms.
