Abstract

To investigate the prevalence and related risk factors of laryngopharyngeal reflux in otolaryngology. During January 2019 to March 2019, the inpatients in otolaryngology were investigated by the questionnaire of reflux symptom index scale and the laryngopharyngeal reflux related risk factors were analyzed. Among the 227 patients, 33 patients with suspected LPR contained 19 patients(20.7%) of 92 patients in the laryngopharyngeal group, 10 patients(16.1%) of 62 patients in the nasal group, and 4 patients(5.5%) of 73 patients in the ear group. LPR prevalence in the laryngopharyngeal group was statistically different from that in the ear group(<0.05). Univariate logistic regression analysis showed that age, gender, smoking, drinking and BMI were risk factors of LPR(<0.01). Multivariate logistic regression analysis indicated that BMI was an independent risk factor of LPR(<0.01). LPR had a high prevalence rate in otolaryngology related diseases, and appropriate synergistic anti-LPR treatment could be carried out while treating otolaryngology related diseases.
