Abstract：Objective To investigate the clinical application of Methylene Blue staining in preauricular fistula removal.Methods A collection of 133 patients with preauricular fistula admitted to our hospital from January 2015 to June 2019 were selected as the research objects.All patients were in the non-inflammatory period,and the preauricular fistula with infection was completely controlled after 2 weeks of infection.The patients with preauricular fistula and infection were divided into observation group(67 cases)and control group(66 cases)by random number table method.The observation group received Methylene Blue staining one day before the operation and the control group received Methylene Blue staining before the ear fistula removal.All patients were followed up for more than 6 months after operation,and the wound healing,residual fistula recurrence,complications and patient satisfaction were compared between the two groups.Results The incisions in the observation group healed at first stage without recurrence after the operation.There were 2 cases with large preauricular scars after operation,and the total incidence of complications was 2.98%; the patient satisfaction rate was 97.01%.In the control group,there were 6 cases of residual fistula recurrence after the operation,the recurrence rate was 9.09%,and the healing was good after the second operation; 9 cases had large scars after operation,2 cases were infected,and the total incidence of complications was 16.67%; patient satisfaction was 83.33%.The postoperative incision healing rate and satisfaction of the observation group were higher than those of the control group,and the recurrence rate and the total incidence of complications were lower than those of the control group,the differences were statistically significant(P＜0.05).Conclusion Preauricular fistula removal after Methylene Blue staining 1 day before surgery has the advantages of less trauma and fewer complications,which is beneficial to complete removal of fistula lesions,reduces recurrence rate,and improves patient satisfaction.
