Postoperation of preauricular fistula cellulitis caused by methicillin-resistant staphylococcus aureus infection

[The utility of single-incision retrograde surgery for the infection preauricular fistula]

Objective:To investigate the clinical effectiveness of the single-incision retrograde surgery（SIRS） of the infection preauricular fistula. Methods:A retrospective analysis was performed from April 2016 to May 2021. In the observation group, there were 15 cases of infected preauricular fistula using single-incision retrograde surgical excision. Twenty-four infected preauricular fistulas by double-incision surgery（fistula and infection incisions） were selected as the control group. The recurrence rates, wound healing scores, and scar assessment were compared between the two groups. Results:There were no significant differences in recurrence rate and incision healing between groups（P>0.05）, and the preserved fistula in SIRS group were good without infection recurrence. Moreover, The scar score and the surgical wound in SIRS group were better than that in the control group（P<0.05）. Conclusion:The single-incision retrograde surgery is an effective method of treating infected preauricular fistulas with fewer wounds and fewer scars.

Summary of the Experience in the Diagnosis and Treatment of Complex Preauricular Fistulas in 78 Children

Objective: This study aimed to investigate the application of mini-incisions in complex preauricular fistula resection in children.

Methods: A total of 78 children who were diagnosed with preauricular fistula infection between January 2017 and December 2019 were included in the study. Their clinical data were analyzed retrospectively, and surgical treatment with mini-incisions based on plastic surgery principles and techniques was provided.

Results: All the patients achieved healing following the first application of the treatment. The patients were followed up for 6–42 months, and no recurrence or local auricular deformation occurred.

Conclusion: The application of mini-incisions and plastic surgery techniques in complex preauricular fistula resection in children can achieve a good effect and improve the satisfaction of the children and their parents.
