[Exploration between shen and ear by auditory determination in patients with renal disease]

Hearing determination of 51 cases had been made to observe and explore the TCM pathogenic relation between the collateral channels of Shen and ears. Model 51A-T72N pure tone auditional determinator was used. For each case, routine auditional determination was made after rest in bed quietly for an hour after breakfast. The determinating results were divided into normal (average hearing loss less than 15dB), low frequency, high frequency and plain-typing hearing loss.

Among the 51 cases, 8 cases were normal hearing (15.7%), the hearing loss cases were 43 (84.3%); 30 cases were double-ear hearing loss (58.8%); 13 cases were single ear hearing loss (25.5%). Cases of renal diseases frequently occurred among the young (in this group, average age was 29.5 years). Such high incidence was obviously non-physiological, but related to the renal disease itself. More serious hearing damage were seen and were in high frequency. Whether or not it was caused by hypoalbuminaemia, oedema and deprivation in blood vessel leading to disorder of circulation of sound sensitizen, or accumulation of toxin owing to renal dysfunction, or changing composition of endolymph influencing the hearing bristle cells, further research should be done in the near future.
