[The effect factor and pure threshold average of the ear with normal hearing in patients with single sided deafness].

Abstract

Objective:To learn the hearing level and analyze the effect factors of hearing loss of the ear with normal hearing in patients with single sided deafness, and provide references for the treatment of single sided deafness. Methods:A retrospective analysis of pure threshold average of 89 patients with single sided deafness, it was divided into six groups,0-6 month group （14 cases）, >6-12 month group （17 cases）, >12-18 month group （15 cases）, >18-24 month group （26 cases）, >24-30 Month group （10 cases）, >30-36 months group （7 cases） in accordance with the different duration of deafness, and compare the pure threshold average of each group; In accordance with the different ages of onset of deafness, it was divided into four groups, 21-30 years old group（18 cases）, >30-40 years old group （24 cases）, >40-50 years old group （30 cases）, >50-60 years old group （17 cases）, and pure threshold average of matching age of normal hearing was compared. Spearman correlation was used to analyze whether gender, side, age of onset of deafness, etiology of deafness, duration of deafness, and pure threshold average hearing were correlated. Results:As the duration of deafness in the affected ear increased, the average pure threshold in patients with single sided deafness increased. As the age of onset of deafness increased, there was a statistically significant difference in age-matched normal hearing. Age of onset of deafness and duration of deafness were the main factors affecting the pure threshold average. Conclusion:In clinical work, the degree of attention to patients with single sided deafness should be increased, hearing of the better hearing ear patients should be protected, and the quality of life will be improved.
