[Efficacy and prognosis of an innovative concealed incision approach combined with microscopic excision for preauricular fistula].

The innovative concealed cosmetic incision approach combined with microsurgical techniques not only achieves thorough excision of fistula tissue but also offers an aesthetically concealed incision. Microscopic dissection of the fistula allows clear anatomical visualization without necessitating en bloc removal of preauricular tissue, creating satisfactory wound healing and a safe, reliable procedure. Compared with the traditional preauricular fusiform incision, the innovative concealed cosmetic incision combined with microsurgical techniques offers superior aesthetic outcomes in terms of healing appearance. This incision method is readily mastered by surgeons while meeting the aesthetic expectations of paediatric patients and their families, which is worthy of clinical promotion and application.
