Alternative Agents to Prevent Fogging in Head and Neck Endoscopy

The essential factor for diagnosis and treatment of diseases in head and neck endoscopy is the visibility of the image. An anti-fogging agent can reduce this problem by minimizing surface tension to prevent the condensation of water in the form of small droplets on a surface. There is no report on the use of hibiscrub(®) or baby shampoo to reduce fogging in the literature. The objective of this study was to compare the efficacy between commercial anti-fogging agent, hibiscrub(®) and baby shampoo to reduce fogging for the use in head and neck endoscopy.
