Question

Why should I try the SYNAPSYS VNG wireless system by Inventis for my patients?

Answer

SYNAPSYS VNG is a video nystagmography system created by Inventis that is ideal for a complete vestibular analysis. Otolaryngologists, audiologists, and physiotherapists can investigate vestibular functionality by finely analyzing eye movements. Automatic post-processing of the image helps identifies the nystagmus. By using state-of-the-art infrared cameras mounted on goggles, the patient’s eye movements are recorded by the software. Thanks to the eye tracking system, VNG instantly detects the pupils without any adjustment required, even when it comes to difficult situations such as dark eyelids.

SYNAPSYS VNG offers a wide and complete range of tests: Saccade, Smooth Pursuit, Gaze, Optokinetic, Nystagmus, Caloric, Kinetic, and Subjective Visual Virtual. The presence of complete normative data with which to compare results, the possibility to insert markers in real-time and select different tracking modes (graphs, tables), as well as the available pre-loaded test protocols, make the software extremely reliable and easy to use.

The wireless camera grants an unparallel user experience in terms of patient mobility, freedom of movement, and flexibility of use.

For a long time, we have worked to optimize WI-FI communication and obtain full-resolution videos (no low-quality regions) with the aim of speeding up the execution of vestibular tests and improving users' understanding of video images in order to formulate more precise diagnoses.

As this is a wireless system, the maximum flexibility of movement is guaranteed for both the patient, who wears the mask, and for the operator who manages the test and provides the instructions to the patient. This is a great advantage in particular with kinetic tests.

The wireless camera also supports a binocular system. The simultaneous use of two cameras (both wireless) so the possibility to capture the visual and graphic analysis of the nystagmus kinetics on both eyes at the same time, not only reduces the test timing but also allows to detect possible asymmetries, and evident signs of pathologies.

SYNAPSYS VNG is also available with a standard wired camera and, optionally, a second camera can be added to allow binocular recordings. An advanced high-frequency bi-ocular analysis is also available with the Visio Mask. Specifically designed for oculomotor testing, it analyses both eyes simultaneously, allowing a true open-field view.

SYNAPSYS VNG can also be combined with the rotary chair to complete your battery of videonystagmographic tests with rotational kinetic exams. Sixteen stimulation waveforms are available, including various sinewave forms, multifrequency, speed step, and sudden stop tests.

SYNAPSYS VNG is fully controllable by the software Maestro, the core of your Inventis equipment set-up.

With Maestro, you can manage patient data, and run, review and combine exams.

Over the past five years, we have seen a growing interest in studying vestibular disorders in children. The most commonly noteworthy are vestibular disorders in congenital sensorineural hearing loss (SNHL) and cochlear implants. Identifying and diagnosing vestibular and balance dysfunction in children is essential for their overall well-being. However, the diagnosis process is very demanding.This talk will provide an overview of vestibular and balance assessments in children with SNHL.

Besides typical symptoms and signs (including pulsatile tinnitus, hyperacusis, pressure/sound-induced torsional nystagmus, conductive hearing loss and lowered thresholds of air-conducted VEMPs) an analysis of the relevant literature reveals a certain clinical polymorphism induced by superior canal dehiscence (SCD). In addition to asymptomatic persons or subjects with SCD presenting exclusively with cochlear symptoms (only partly explained by the so-called “near-dehiscence syndrome”), SCD cases mainly presenting with atypical/refractory/recurrent positional vertigo and/or Meniere-like vertigo spells have been recently described. Moreover, if surgical occlusion of the superior canal (SC) results in symptoms control inducing a selective SC hypofunction, clinicians my sometimes accidentally detect a reduced SC VOR gain in asymptomatic patients with wide-sized dehiscence. These findings led authors to propose the occurrence either of a natural SC plugging (complete or incomplete) by middle fossa dura prolapsing into the canal lumen or a dispersion of mechanical energy through the dehiscence. Typical and atypical scenarios is presented. A subsample of patients from the personal series with a complete otoneurologic assessment (audiometry, VOG eye recording, air/bone-conducted cervical/ocular VEMPs, video head impulse test) is selected to explain these emerging theories on possible pathomechanisms.
