Abstract:Objective To study the application of Semont tube stone relief combined with alprostadil in otolith patients and the influencing factors of residual symptoms.Methods A total of 120 otolith patients who were treated in Tianjin Hospital from January 2018 to December 2019 were selected as the research objects. According to the principle of random grouping, the above patients were randomly divided into the observation group and the control group, with 60 cases in each group. Both groups were treated with Semont tube stone relief method, and the patients in the observation group were treated with alprostadil on this basis. The difference between the two groups in treatment effect, quality of life, and follow-up were compared, and the risk factors of postoperative residual symptoms were analyzed.Results Compared with the control group, the treatment of the observation group was better (P < 0.05), and the total effective rate (90.00%) was significantly increased (P < 0.05); after treatment, the DHI scale indexes of the two groups were significantly decreased, and the function, emotion, body, and total score were significantly decreased in the observation group (P < 0.05); the patients without residual symptoms in the observation group were significantly higher than those in the control group, and the patients with residual symptoms and recurrent otolith were significantly lower than those in the control group (P < 0.05); there were statistically significant differences in onset month, sleep disorder, DHI scale score, hypertension, diabetes mellitus, and coronary heart disease between patients with and without residual symptoms (P < 0.05); the onset month was from December to February [O^R= 1.63 (95% CI: 1.33, 2.32)], sleep disorder [O^R = 1.06 (95% CI: 0.75, 2.11)], DHI scale score [O^R = 2.12 (95% CI: 1.36, 2.62)], Hypertension [O^R = 1.12( 95% CI: 1.02, 1.20)], diabetes [O^R = 0.71 (95% CI: 0.52, 0.94)], coronary heart disease [O^R = 2.01 (95% CI: 1.56, 2.30)] were independent risk factors for residual symptoms after treatment.Conclusion The combination of Semont tube stone relief method and alprostadil has a significant therapeutic effect on otolith patients, with a low recurrence rate. At the same time, winter, sleep disorders, high DHI score, hypertension, diabetes and coronary heart disease will aggravate the residual symptoms of otolith.
