A statistical analysis was made on 1820 patients who visited our clinic, complaining of vertigo and dizziness from 1977 to 1986.
The number of patients was increasing, especially patients over 65 years old. Otological origin occupied 32% (Meniere's disease 10%), and unknown origin 47%. Vestibular dysfunction due to ototoxic drugs (KM. SM), cerebrovascular disorder, and vertigo following head trauma were predominant in males, vertigo due to hypotension was in females.
Brain tumor and origin unknown vertigo were predominant in the patients under 15years old, sudden deafness with vertigo in those between 15 and 65 years old, vestibular dysfunction due to ototoxic drugs (SM. KM) and vertigo due to hypotension in those over 65 years old.
Half of the patients complained of vertigo and one third complained of dizziness.
