Videostroboscopy Equipment List: Stroboscope, Scope, Camera, Microphone and Software

The core components of a videostroboscopy set

The set has five parts. The LED stroboscope produces flashes synchronised to the voice. A rigid transoral or flexible transnasal laryngoscope carries the light to the larynx and the image back. A camera converts the image to video, a microphone or sensor measures the fundamental frequency, and a monitor and recording software show and archive the examination.

Because the strobe depends on the voice frequency, the microphone and the frequency-detection electronics are as important as the light itself. For an overview of the technique itself, see our article on videostroboscopy.

Hygiene belongs on the list as well. Rigid and flexible scopes are reprocessed between patients according to the manufacturer and your infection-control policy, so plan enough scopes to cover the daily caseload without delays.

Choosing a laryngoscope stroboscope and LED light source

A laryngoscope stroboscope used to be built around xenon lamps; the LED stroboscope has replaced them in many clinics for its long life and silent operation. Compare the brightness delivered through your scope, the flash frequency range, how the unit tracks voice frequency, and the available modes: slow motion, freeze image and continuous light.

The ATMOS Strobo 21 LED has a flash frequency of 70–1000 Hz, a sound level range of 70–125 dB, a power consumption of 30 W and dimensions of 118 × 139 × 280 mm. It works in slow motion, freeze image with a phase shift of 0°–400° set via the foot controller, and continuous light. An LED light source and an airborne sound microphone are included, and it can be integrated into an ENT treatment unit or used as a tabletop device.

• Flash frequency range and accuracy of frequency tracking.
• Modes: slow motion, freeze image, continuous light.
• Foot control of mode and phase shift.
• Included microphone and display of frequency and sound pressure level.

Scope, camera and software: the image chain

A rigid 70° or 90° telescope usually gives a brighter and sharper image of the folds, while a flexible nasolaryngoscope can be used when a rigid scope is not tolerated or when speech tasks need to be examined. Many voice clinics have both, because each answers different questions.

Camera resolution, light sensitivity and the connection to the scope all affect results. Check that the light cable connector fits your stroboscope, that the camera works with the scope and that the recording software stores audio with the video. A voice clinic builds a record of patients over time, so file formats and storage should be planned from the beginning.

A foot controller keeps both hands on the scope and the camera, which makes it one of the most practical features to check in a demonstration.

Videostroboscopy cost: what drives it

We do not quote figures, but videostroboscopy cost depends on a few clear factors: whether you already own scopes and a camera, whether you want an integrated stroboscope in an ENT workstation or a tabletop unit, the resolution of the camera, the recording software, and the training and service package. Compare quotes on the same list of components.

A staged approach works: start with the stroboscope and an existing rigid scope, and add a flexible scope or a better camera later. Check the full ENT room plan in our ENT clinic equipment list. Installation and training should be part of the offer.

Ask what is covered by the warranty, how quickly a replacement LED module or microphone can be supplied and whether software updates are included.
