[Clinical features and advanced progress of secondary BPPV]

Area of Science:

• Neurology
• Otolaryngology

Background:

• Benign paroxysmal positional vertigo (BPPV) is a common inner ear disorder characterized by sudden, brief episodes of vertigo and nystagmus triggered by specific head movements.
• BPPV is broadly classified into idiopathic (unknown cause) and secondary (attributable to a specific cause) forms, with secondary BPPV accounting for approximately 30% of cases.

Purpose of the Study:

• To comprehensively review the pathogenesis, underlying mechanisms, clinical manifestations, and therapeutic strategies for secondary BPPV.
• To highlight the latest advancements and research progress in the understanding and management of secondary BPPV.

Main Methods:

• Literature review of scientific articles and clinical studies focusing on secondary BPPV.
• Analysis of data related to the etiology, diagnosis, and treatment outcomes of secondary BPPV.

Main Results:

• Secondary BPPV can arise from various underlying conditions, including head trauma, vestibular disorders, and surgical interventions.
• Understanding the specific cause is crucial for effective management and improving patient prognosis.
• Current treatments often involve repositioning maneuvers, but further research is needed for specific secondary causes.

Conclusions:

• Secondary BPPV represents a significant subset of BPPV cases requiring targeted investigation and treatment.
• Further research into the specific etiologies and tailored therapeutic approaches for secondary BPPV is warranted.
• Improved diagnostic and therapeutic strategies can enhance patient outcomes for secondary BPPV.
