  • Title: A practical assessment algorithm for diagnosis of dizziness.
    Author: Kentala E, Rauch SD.
    Journal: Otolaryngol Head Neck Surg; 2003 Jan; 128(1):54-9. PubMed ID: 12574760.
    Abstract:
    OBJECTIVE: We sought to test a 3-parameter model for diagnosis of dizziness based on the type and temporal characteristics of the dizziness and on hearing status. STUDY DESIGN AND SETTING: We conducted a prospective blinded study at a tertiary referral neurotology practice. Before examination, patients completed a questionnaire reporting type and timing of dizziness symptoms and hearing status. Clinical diagnoses were compared with questionnaire results. RESULTS: Fifty-seven patients completed the questionnaire. We were able to correctly classify 21 (60%) of the 35 subjects who had a common otogenic cause of vertigo by the diagnostic algorithm. CONCLUSION: A simple classification of dizziness by type, timing, and hearing status can be self-reported by patients using a brief questionnaire. This classification scheme is as good as others of much greater complexity. SIGNIFICANCE: The simple classification scheme reported here is based on history alone and facilitates triage of dizzy patients into diagnostic groups for work-up and management.
