The skin accounts for 12-24% of body weight and is the largest organ of the body. A multitude of skin-related pathologies are among the most common causes for consultation in everyday clinical practice1, including atopic dermatitis, pyoderma and otitis, among others. Furthermore, many of these pathologies can be associated with endocrine and systemic diseases that affect the skin.

Depending on the pathology and its underlying causes, multimodal treatment is often essential given that many of these pathologies can sometimes be frustrating in terms of treatment and results. This is why attempts are made to find all the therapeutic options that can help achieve an improvement in these patients. 

The benefits of laser therapy in the field of rehabilitation and veterinary sports medicine are widely known, whereas dermatology is currently the field where a greater interest can be observed in laser therapy. However, the beginnings of therapeutic laser technology are said to have begun when Dr. Endre Mester – considered to be the father of laser therapy – undertook research on skin cancer in mice, observing that laser therapy did not cure the disease but the skin of mice did indeed grow faster2.

Many studies with animals and humans have been conducted on wounds since the early days of therapeutic laser technology to reveal the benefits of this therapy3-5. It is being used more and more often in veterinary medicine with wound healing and post-surgery incisions6,7.

When considering the general effects of laser therapy (see General Effects, Inflammation and Infection), it should not be limited to wounds in dermatology but should include various infection problems, allergies that lead to skin problems and alopecia of varying origin, which can all benefit from laser therapy. Numerous laboratory and human studies show the benefits of therapeutic laser in dermatology8-10.

Studies are starting to appear in veterinary medicine on various dermatological pathologies treated with laser. Despite a need to unify the parameters and conduct more studies, the results from studies completed already are very promising11,12.

Due to the huge range of pathologies that can affect the skin, a precise diagnosis is essential for creating a correct laser therapy protocol. The pathology must be known before setting the intended goals for any laser therapy.

DoctorVet has specific protocols for skin wounds and lesions, as well as protocols for infections and inflammation. A combination of different protocols may be recommendable depending on the specific pathology in question, which should always be adapted to the area affected.

DoctorVet has two treatment heads for use on the skin – the zoom head and the sweeper head. The sweeper head in non-contact mode is the one used most often. The treatment schedule will vary according to the pathology presented by the patient.
