[Assessment of Flexible Single-Use Rhinolaryngoscopes with Working Channel in the Upper Airways]

Area of Science:

• Otolaryngology
• Medical Device Technology
• Infection Control

Background:

• Flexible rhinolaryngoscopy is a common ENT procedure, typically using reusable endoscopes.
• Increasing hygiene standards for reprocessing reusable endoscopes present challenges.
• Single-use flexible rhinolaryngoscopes with and without working channels are now available.

Purpose of the Study:

• To evaluate user satisfaction with the Ambu disposable endoscopy system with a working channel.
• To compare single-use flexible rhinolaryngoscopes with traditional reusable systems.

Main Methods:

• A bicentre observational study was conducted.
• User satisfaction was assessed using questionnaires.
• Key performance indicators included overall impression, image quality, and handling.

Main Results:

• Half of the applications rated the disposable system's overall impression as "very good".
• Image quality and handling were predominantly rated "good" to "very good".
• Simultaneous instrument use via the working channel was identified as a challenge.

Conclusions:

• Single-use rhinolaryngoscopy systems provide high user satisfaction, excellent handling, and image quality.
• These systems offer enhanced safety regarding contamination and complication risks.
• Disposable endoscopes may offer a cost-effective and hygienic alternative to reusable systems, especially with integrated working channels.
