“As a user of the ENTviewer videoscope, I’d like to share my opinion about this device.
The basic advantage of this imaging system is user-friendliness, possibility of connecting the device with the computer used in the clinic, simple procedure for archiving the images and saving them on other carriers via pendrive, email, disc or printout.
Thus, it is possible to provide the patient with an ENT examination result not only in the form of a description, but also a recorded image, as in the case of ultrasound examination. It also helps to make the examination description more objective and show it’s quality.
The camera placed in the device allows for visualisation of places that are hard to reach during the ENT examination.
The examination itself does not require anaesthesia, as it is short; while the patient’s reflexes in fact often make it easier to see such places as nasopharynx and posterior nasal apertures otherwise hidden behind the soft palate, or to expose the larynx covered by flat epiglottis, without the need to additionally pull the anatomic elements which cover up the image. Pulling of the palate with a classic method of placing a catheter through the nose or lifting the epiglottis with the directoscope requires local or general anaesthesia, which significantly exceeds the time of the examination and makes it practically impossible within the timeframe of a regular visit at the laryngological clinic.
Pharyngeal reflexes are the main drawback of the examination with the use of laryngeal mirror. Children fear this examination, as they are afraid of pharyngeal reflex. Therefore, the time during which the sensitive area is provoked is key, and this time is reduced to the minimum. It is important to locate a camera in a place that allows for visualisation of the larynx or nasopharynx, while the image analysis is performed upon the completion of the examination, on the computer screen.
In larynx imaging with the use of the Sinutronic videoscope, proper lighting of the larynx structures is of utmost importance. This may be achieved by assessment during phonation, which is necessary to cause the videostroboscopy effect.
Finding a solution to the problem of device sterility in ENTviewer videoscopes ensures good quality of each examination and does not speed up the wear of the tip due to sterilisation. Nowadays, reusable tools tend to be replaced by disposable devices. We observe this tendency especially on the American market, where only disposable surgical drill or diathermy tips are used. Patients have aesthetic concerns and are not confident as to the complete sterility and quality of reusable tips.
Unfortunately, in our country, switching from reusable devices into disposable ones does not guarantee good quality. Nasal specula or disposable mirrors are made of plastic in a standard one size. This very fact deteriorates the quality of the ENT examination, as different sizes of mirrors or nasal specula ensured that the tools could be adapted to the individual examination. In my opinion, the ENTviewer eliminates the need to use such tools as plastic laryngeal mirrors and provides easy access to areas that are hard to diagnose.”
