Low level laser therapy: An effective tool to enhance quality of life in head and neck cancer survivors

Abstract

Patients treated for head and neck cancer commonly suffer from oral mucositis, ulceration, bacterial infection causing pain, discomfort, impairment of speech and deglutition, leading to dehydration, poor nutrition, and mortality. Low level laser therapy (LLLT) is a promising state-of-the-art method which can be used effectively to reduce these side effects. It works on the principle of photo-bio stimulation. LLLT induces a biological response through energy transfer within the cells. It has anti-inflammatory effects, stimulates the immune system, increases of blood flow, upsurges cellular metabolism, and boosts rapid wound healing.
