Dermatological Surgery

Dermatological surgery, also known as dermatologic surgery, is a specialized field within dermatology that focuses on surgical procedures to diagnose and treat skin, hair, and nail disorders. As a crucial part of modern dermatology practice, it plays a vital role in improving patient outcomes and quality of life.

Overview

Dermatological surgery encompasses a wide range of procedures, from minor cosmetic treatments to major reconstructive surgeries. These procedures may involve both diagnostic and therapeutic interventions, often requiring a combination of clinical expertise and technical skill.

Key Principles

  1. Minimally invasive techniques
  2. Preservation of tissue integrity
  3. Emphasis on patient safety and comfort
  4. Integration with other dermatological treatments (e.g., pharmacotherapy)

Common Procedures

1. Skin Cancer Excision

Skin cancer excision is one of the most common dermatological surgical procedures. It involves removing suspicious skin lesions to determine if they are malignant.

Types of Skin Cancers Treated:

  • Basal cell carcinoma
  • Squamous cell carcinoma
  • Melanoma

Procedure Steps:

  1. Local anesthesia administration
  2. Incision around the lesion
  3. Removal of the entire tumor with a margin of healthy tissue
  4. Closure of the wound

Example:

A 65-year-old man presents with a pigmented nodule on his ear. After biopsy confirmation of melanoma, he undergoes wide local excision with sentinel lymph node biopsy.

2. Mohs Micrographic Surgery

Mohs micrographic surgery is a highly effective technique for treating skin cancers, particularly basal cell carcinomas and squamous cell carcinomas.

Procedure Steps:

  1. Application of local anesthesia
  2. Removal of the visible tumor
  3. Examination of the removed tissue under a microscope
  4. Repeated removal and examination until clear margins are achieved

Advantages:

  • High cure rate (up to 99% for certain types)
  • Minimal scarring
  • Preserves surrounding normal tissue

3. Liposuction

Liposuction is a popular cosmetic procedure used to remove excess fat deposits from various body areas.

Procedure Steps:

  1. Administration of local or general anesthesia
  2. Insertion of cannulas into the fatty tissue
  3. Suctioning out the fat cells
  4. Closing of incisions

Considerations:

  • Multiple sessions may be required for optimal results
  • Risk of complications such as infection or scarring

4. Chemical Peels

Chemical peels are non-surgical procedures that use chemical solutions to remove the top layers of the skin, revealing smoother, brighter skin underneath.

Types of Peels:

  • Light peels (lunchtime peels): Glycolic acid, lactic acid
  • Medium peels: Trichloroacetic acid (TCA)
  • Deep peels: Phenol

Procedure Steps:

  1. Preparation of the skin
  2. Application of the peel solution
  3. Neutralization of the peel
  4. Post-procedure care

Examples:

  • Glycolic acid peel for acne-prone skin
  • TCA peel for fine wrinkles and age spots

Preoperative Care

Before undergoing dermatological surgery, patients should:

  1. Stop smoking and avoid alcohol consumption
  2. Inform their doctor about all medications and supplements
  3. Avoid aspirin and blood-thinning medications
  4. Follow specific dietary instructions

Intraoperative Care

During the procedure:

  1. Maintain proper hygiene and sterile conditions
  2. Use appropriate anesthesia based on the procedure and patient needs
  3. Ensure adequate lighting and magnification tools
  4. Take regular breaks to prevent fatigue

Postoperative Care

After the procedure:

  1. Follow wound care instructions carefully
  2. Attend post-operative check-ups
  3. Report any signs of infection or complications promptly
  4. Adhere to medication regimens prescribed by the surgeon

Complications and Risks

Common complications include:

  • Infection
  • Scarring
  • Bleeding
  • Nerve damage
  • Allergic reactions to medications

Less common but serious risks include:

  • Recurrence of skin cancer
  • Lymphedema (especially after lymph node dissection)
  • Systemic side effects from anesthetics

Advancements in dermatological surgery include:

  • Minimally invasive techniques
  • Robotic-assisted surgery
  • Personalized medicine approaches
  • Combination therapies (e.g., laser-assisted surgery)

Conclusion

Dermatological surgery is a dynamic and evolving field that requires continuous learning and adaptation. As healthcare providers, it's essential to stay updated on the latest techniques, technologies, and best practices to provide the best possible care for our patients.

Remember, while this guide provides a comprehensive overview, each case is unique. Always consult current medical literature and seek guidance from experienced professionals when dealing with real-world scenarios.
