Vestibular disorders: clinician ENT perspective on the need for research and innovation

Vertigo and dizziness are a frequent reason for medical consultation. However, diagnostic and therapeutic management is sometimes limited, and clinicians are faced with many unmet needs. The purpose of this study was to identify and prioritize these needs.

A questionnaire methodology was used to determine the need for innovation in vestibular disorder management. The questionnaire was sent to 19 teams in French-speaking ENT centers. We measured the concordance of the panel of experts on 56 questions related to the different vestibular pathologies encountered and the desired modalities of innovations.

Thirteen questions were identified as priorities. The needs expressed by the experts had better knowledge of the pathophysiological mechanisms of the main diseases encountered and the development of new treatment modalities. Particular attention was paid to inner ear imaging techniques and the development of specific electrophysiology techniques.

Some of the anticipated innovations are already under development, such as new inner ear fluid imaging techniques (hydrops visualization using MRI) or in situ treatments (transtympanic dexamethasone or gentamicin injections). Others, such as new electrophysiological techniques, are still not fully developed CONCLUSION: This study provides a snapshot of the needs of the medical profession in vestibular disorder management. It highlights a real concern of the attending personnel, as well as a critical need to optimize the means of diagnosing and treating patients with vestibular disorders.
