Laser Therapy Versus Electromagnetic Field on Mucosal Membrane Thickening in Children With Chronic Rhinosinusitis.

Rhinosinusitis is a frequent disease in children but may be underdiagnosed, that is to say, several causes of the disease are missed in children. Therefore, it seems essential to provide other modalities to treat chronic health conditions like such cases. This controlled clinical study was conducted to compare the effect of two non-pharmacological, painless, safe modalities; low-level laser therapy (LLLT), with pulsed electromagnetic field (PEMF) on mucosal membrane thickening in children with chronic rhinosinusitis.
