Cryotherapy and dermatosurgery

Dermatologic Surgery

Dermatologic surgery is performed by all dermatologists. Surgery is an integral part of dermatology residency training, thus all dermatologists are well trained in cutaneous surgery. Techniques available to a dermatologic surgeon include lasers, traditional scalpel surgery, electrosurgery, cryosurgery, photodynamic therapy, liposuction, blepharoplasty (cosmetic eyelid surgery), minimally-invasive facelift surgery (e.g., the S-lift), and a variety of topical and injectable agents such as dermal fillers, including fat transfer and hyaluronic acid. Some specially trained dermatologic surgeons perform Mohs’ surgery, which can be an effective method for the treatment of recurrent, indistinct, or difficult skin cancers.

Others include:

  • Cosmetic Surgery

  • Hair Transplantation
  • Scars

  • Vascular lesions
  • Benign tumors
  • Acne
  • Pigmented lesions
  • Viral infections
  • Inflammatory dermatoses
  • Infectious dermatoses
  • Pre-malignant and malignant tumors


Cryotherapy is a controlled and targeted destruction of diseased tissue by the application of low temperatures. It is a simple, cost-effective, efficacious and aesthetically acceptable modality for the treatment of various dermatoses.

In the present age, despite the advent of several ablative procedures like radiofrequency or laser therapy, cryosurgery continues to occupy a very important position in the therapeutic scope of a dermatologist. It is a very safe, inexpensive, reproducible, and time efficient that many procedures can be done at the office. It requires a short preparation time, is a sutureless procedure with minimal risk of infection and no anesthesia is usually required. Cryotherapy can be performed at any age, including elder patients with pacemakers in whom electrocautery is contraindicated, those on anticoagulants, patients allergic to anaesthetic agents, patients with transmissible conditions such as human immunodeficiency virus (HIV) and hepatitis, and can also be performed during pregnancy and over most body sites. It provides high healing rates even in difficult areas, with excellent cosmetic results if performed appropriately. In view of all these advantages, it is regarded as a treatment of choice by many dermatologists for various benign and malignant dermatoses.
