1. Introduction

Hernias, though commonly associated with general surgery, have emerged as a pivotal concern within the realm of plastic surgery. The pursuit of beauty, body contouring, and esthetic excellence often leads patients to consider procedures like abdominoplasty (commonly known as a tummy tuck). However, the success and safety of these esthetic surgeries are intricately intertwined with the state of the abdominal wall, which can be compromised by the presence of hernias.

In this chapter, we embark on an illuminating journey into the evolving landscape of hernia management, exploring recent advancements, cutting-edge techniques, and critical considerations that have the power to redefine patient outcomes in the context of plastic surgery.

2. Understanding hernias and their implications

Before delving into the latest developments, it’s crucial to understand the nature of hernias and their implications. Hernias manifest as the protrusion of organs or tissues through weakened areas in the abdominal wall. While they may vary in location and presentation, common types include inguinal, femoral, umbilical, incisional, and ventral hernias [1]. These vulnerabilities in the abdominal wall are often attributed to factors such as pregnancy, the relentless march of time, obesity, or the consequences of prior surgical interventions. It is within this backdrop that hernias emerge as critical players in the intricate dance of plastic surgery.

2.1 Hernia types and characteristics

Inguinal hernias: Inguinal hernias, the most common type, occur in the groin area. They can be further classified as direct or indirect, depending on their anatomical location. Understanding the specific type and characteristics of inguinal hernias is essential for accurate diagnosis and treatment planning.

Femoral hernias: These hernias are less common but tend to occur more frequently in women. They protrude through the femoral canal, often presenting as a painful lump in the upper thigh.

Umbilical hernias: Umbilical hernias manifest near the navel and are commonly observed in infants. However, they can persist into adulthood, especially in cases of weakened abdominal walls.

Incisional and ventral hernias: Incisional hernias arise at the site of a previous surgical incision, while ventral hernias occur elsewhere on the anterior abdominal wall. Both types are closely associated with prior surgeries and necessitate a tailored approach to repair.

2.2 Factors leading to abdominal wall weakness

The abdominal wall serves as a protective barrier for the abdominal cavity. It comprises multiple layers of muscle and fascia, and its integrity can be compromised by various factors:

1. Pregnancy: The stretching of abdominal muscles during pregnancy can weaken the abdominal wall, predisposing individuals to hernias.

2. Aging: As we age, our muscles and connective tissues naturally lose some of their strength and elasticity, making hernias more likely.

3. Obesity: Excess body weight can exert pressure on the abdominal wall, increasing the risk of hernia formation.

4. Previous surgeries: Surgical incisions can weaken the abdominal wall, especially if not adequately closed or if there are complications during the healing process.

3. Hernias and esthetic surgery implications

In the context of plastic surgery, hernias become a significant consideration, particularly for procedures like abdominoplasty (tummy tuck). The success of these esthetic surgeries relies on the integrity of the abdominal wall. A compromised abdominal wall can impact both the functional and cosmetic outcomes of the procedure [2].

Understanding the types, causes, and implications of hernias lays the foundation for exploring the advancements and techniques that have reshaped hernia management within the field of plastic surgery. In the sections that follow, we will delve into the latest innovations in hernia repair techniques, mesh materials, combined procedures, recurrence prevention, diagnostic advances, and the promising future of hernia management.

4. Advancements in hernia repair techniques

In recent years, a wave of technological innovation and medical advancements has transformed the approach to hernia repair. Gone are the days of one-size-fits-all solutions; today’s surgeons are equipped with a diverse toolkit to address hernias comprehensively.
