[Expert consensus on the diagnosis of isolated otolith dysfunction]

Area of Science:

• Neurology
• Otolaryngology
• Vestibular Medicine

Context:

• Isolated otolith dysfunction (iOD) is a group of vestibular syndromes characterized by abnormal otolith function and normal semicircular canal function.
• Recent years have seen increased attention to iOD, with published case reports, clinical studies, and diagnostic criteria.
• There is currently no consensus document to guide the diagnosis of iOD in China.

Purpose:

• To establish a diagnostic consensus for isolated otolith dysfunction (iOD) in China.
• To provide guidance for the clinical diagnosis and management of iOD.
• To promote best clinical practices for iOD.

Summary:

• Isolated otolith dysfunction (iOD) presents with symptoms like translation, tilting, or floating sensations and blurred vision during head movements.
• Diagnostic criteria involve normal semicircular canal function but abnormal otolith function on laboratory vestibular testing.
• This consensus was formulated by domestic experts in vestibular medicine based on current evidence.

Impact:

• Aims to standardize the diagnosis and management of iOD in China.
• Expected to improve clinical practice and patient outcomes for iOD.
• Facilitates further research and understanding of iOD.
