AI Article Synopsis
- This study analyzed 20 cadaver samples of three types of fascia: pectoral fascia, fascia lata, and ventral rectus sheath, using various staining techniques and histological evaluations on a total of 1200 slides.
- Findings showed that the pectoral fascia had the greatest thickness (612 μm) and most elastic fibers (12.24%), while the fascia lata was the thinnest (84 μm) with the least elastic fibers (6.54%).
- Statistical comparisons indicated significant differences between the fascia lata and the other two types, while there were no significant differences between pectoral fascia and ventral rectus sheath, highlighting unique morphological characteristics that contribute to a deeper
Article Abstract
The aim of this study was to characterize and compare the morphological and histomorphometric characteristics of the pectoral fascia, fascia lata and ventral rectus sheath. Twenty cadaveric samples of these fascias were analyzed and stained with hematoxylin and eosin, orcein, Van Gieson, Masson's trichrome and Verhoeff¨s stain (1200 slides in total). Morphological evaluation, semiquantitative, morphometric and microdensitometric analysis of elastic fibers present in each of the tissues and a morphometrical analysis of tissue thickness were performed. The mean value of the pectoral fascia thickness was 612±68.13 μm; 84±246 μm for the fascia lata and 584±92 μm for the ventral rectus sheath. The area occupied by the elastic fibers in the pectoral fascia was 12.24±5.84%; 6,54±3.85% for the fascia lata and 11.11±5.26% for the ventral rectus sheath. There were no statistically significant differences when comparing the mean values between the pectoral fascia and the ventral rectus sheath (p=0.07). There were statistically significant differences when comparing the fascia lata to the pectoral fascia and the ventral rectus sheath (p≤0.001). This study reports other morphological characteristics not described in previous histological studies of the analyzed tissues. The results of the morphometric and densitometric analysis in this study reveal that the fascia lata has the fewest elastic fibers of all the tissues analyzed, and the pectoral fascia has the most. These results will be useful for the beginning of a morphological information bank of human fascias.

Background: Autologous fat (AF) grafting is widely used in plastic surgery and is generally considered a safe and effective procedure. A combined approach utilizing vibration amplification of sound energy at resonance (VASER) to prepare AF grafts with a 4-layer fat grafting technique was explored in this study.

The sternalis muscle is a rare anatomical variant located in the anterior thoracic wall. Understanding variations in the sternalis muscle anatomy is essential for clinicians, especially radiologists and surgeons to prevent misdiagnosis and avoid complications during surgical procedures in the anterior thoracic region. We present a unique case of bilateral branched sternalis muscles.

Purpose: To report the morphologic and spatial relationships of a bilateral sternalis muscle variant.
Methods: Routine cadaveric dissection in an undergraduate anatomy laboratory revealed two sternalis muscles parasternal to the sternal body. Subsequent fine prosection of the anterior thoracic wall and neck was carried out to uncover the soft tissue attachments of both sternalis muscles.

Article Synopsis
- * A total of 60 male patients underwent the procedure (2010-2023), where liposuction and periareolar excision were performed, with an average of 300 mL of tumescent solution used per breast, resulting in minimal complications.
- * The findings indicate that this outpatient method is both effective and safe, with a low rate of major (6.7%) and minor (5%) postoperative complications, and patients reported no pain during the surgery.

Traditional transvenous pacemakers consist of a pacemaker generator usually positioned surgically in the upper left chest on the pectoral muscle fascia and one or more leads positioned through the veins to the right atrium and across the tricuspid valve to the right ventricular apex. While these devices reduce symptoms and improve survival among patients with symptomatic bradycardia, they are associated with an increased risk of infection, venous occlusion, heart failure, and tricuspid valve regurgitation. Although new pacemaker designs minimize these risks, none of the current-generation pacemaker designs effectively eliminate all of them.
