Clinical efficacy of salivary gland endoscopy assisted oral resection for larger submandibular gland stones
Objective To observe of the clinical efficacy and safety of endoscopic assisted oral resection of submandibular gland stones larger than 7 mm.Methods A retrospective analysis was conducted on patients with submandibular gland stones＞7 mm treated in the Zhengzhou Central Hospital from April 2020 to April 2022.They were divided into a treatment group of 60 patients who underwent salivary gland endoscopic assisted oral resection and a control group of 60 patients who did not un-dergo endoscopic open surgery.Clinical and ultrasound follow ups were conducted on all patients at 1 month and 1 year after surgery to investigate symptom relief and stone recurrence,and subjective results were evaluated through questionnaires.Results One month after surgery,the VAS score,residual stones,and the need for further treatment rate in the treatment group were lower than those in the control group,while the rate of preserving intact glandular tissue was higher than that in the control group,and the difference was statistically significant(P＜0.05).One year follow-up showed that there was no statistically significant difference in the rates of symptom disappearance,recurrent obstruction,recurrent infection,and re-treatment within one year between the two groups(P＞0.05).The total incidence of complications in the early stage(1 month after surgery)of the treatment group was lower than that of the control group((P＜0.05)),with no significant difference in edema,pain discomfort,and temporary tongue nerve injury between the two groups(P＞0.05).There was no significant difference in the total incidence of complications,pain discomfort,and glandular stenosis in the late stage(1 year after sur-gery)between the two groups(P＞0.05).Conclusion Endoscopic assisted oral resection of large submandibular gland stones is safe and effective,preserving the function of the main ducts and glands and reducing residual stones.
