Analysis of the relationship between different semicircular canals BPPV and complaints symptoms
Objective To analyze the characteristics of complaint symptoms of positional vertigo in pa-tients with benign paroxysmal positional vertigo(BPPV)and the correlation between complaint symptoms and the localization diagnosis of BPPV responsible semicircular canal.Methods A total of 100 patients with posi-tional vertigo from February to March 2022 in this hospital were completed a detailed medical history ques-tionnaire.The objective location diagnosis of BPPV was carried out by video nystagmography and positional test,and the relationship between the diagnosis of BPPV and the complaint of medical history was analyzed.Results Among 100 patients,the main complaints of"sitting up-lying down"and"rolling over"on the bed were 39 and 56 cases respectively,and 5 cases could not distinguish between the two;75 cases were positive in positional test,including 63 BPPV and 12 other peripheral vertigo.In 63 patients diagnosed with BPPV,the sensitivity and specificity of vertical,horizontal semicircular canal BPPV diagnosed by sitting up-lying down were 70.7％and 94.4％,5.6％and 29.3％,respectively,and the sensitivity and specificity of horizontal,verti-cal semicircular canal BPPV diagnosed by rolling over were 94.4％and 70.7％,29.3％and 5.6％respective-ly.Further analysis of the first position of positional vertigo in 63 BPPV patients showed that the sensitivity and specificity of sitting up-lying down to diagnose vertical,horizontal semicircular canal BPPV were 76.9％and 55.6％,44.4％and 23.1％,and the sensitivity and specificity of rolling over to diagnose horizontal,verti-cal semicircular canal BPPV were 55.6％and 76.9％,23.1％and 44.4％.30 patients who could clearly express the side of heavier body position induced by vertigo were analyzed,including 13 patients on the right side,17 patients on the left side,and the remaining 33 patients could not clearly describe the side.Conclusion Among the com-plaint symptoms of patients with positional vertigo,the"sitting up-lying down"and"rolling over"have high sensitivity and specificity in the diagnosis of vertical and horizontal semicircular canal BPPV,which accords with Ewald's Law.However,the sensitivity and specificity for the diagnosis of the responsible semicircular ca-nal side of BPPV are low in the first position and the side position with more severe position.The chief com-plaint symptoms of patients with positional vertigo have a certain clinical value in rapid screening of BPPV,but the location diagnosis depends on the positional test.
