the regular use of flexible nasal endoscopes in the clinical setting of ear,nose and throat (ENT) department is now well-established (Tzanidakis et al,2012).
they are used to examine the anatomy of nasal cavity, the postnasal space, the pharynx and the larynx; when diagnosing denign and malignant disease; and to look for foreign bodies.
like rigid endoscope, flexible nasal endoscope can become contaminated with mucous, debris, micro-organisms and in some cases even blood with each use, and must therefore be decontaminated before use in the next patient.
