Abstract
Dual-incision approach for excision of postauricular sinus.
Highlights
Sir, Preauricular sinus is a common congenital anomaly, which results from developmental failure of embryogenesis during which six hillocks normally fuse to form the auricle
All surgeries were performed under general anesthesia, and a surgical microscope was used for both the precise identification and the delicate dissection of the sinus tract
At the beginning of the surgery, a small amount of crystal violet solution was injected into the lumen of the sinus tract through the opening so that the entire sinus could be clearly identified during the surgery
Summary
Preauricular sinus is a common congenital anomaly, which results from developmental failure of embryogenesis during which six hillocks normally fuse to form the auricle. All surgeries were performed under general anesthesia, and a surgical microscope was used for both the precise identification and the delicate dissection of the sinus tract. At the beginning of the surgery, a small amount of crystal violet solution was injected into the lumen of the sinus tract through the opening so that the entire sinus could be clearly identified during the surgery. A wedge-shape skin incision was made around the sinus opening at the crus of the helix.
