Preauricular Sinus Excision

This procedure is often performed after the infection subsides, with the option of local or general anesthesia. Typically, a modified preauricular approach is used, with microscopic or magnified assistance, to excise the fistula along its course, along with surrounding scar tissue and affected cartilage as appropriate. Probes or dyes may be used for localization if necessary, taking care to protect adjacent structures. Subsequently, layered sutures are performed, drainage is placed as needed, and the specimen is sent for pathology. Postoperative monitoring includes signs of bleeding, swelling, and infection, with the goal of complete fistula removal and promoting healing. The above is general health information and not medical advice; specific details should be based on specialist assessment and hospital protocols.
