Excision and Fat Grafting of Nasal Tip Dermoid Cysts Through an Open Rhinoplasty Approach

摘要

Nasal tip dermoid cysts that are present in pediatric patients can be complicated by mass effect causing compression and distortion of underlying cartilaginous structures. The purpose of this report is to describe a single surgeon's technique and results of nasal tip dermoid cyst excision in pediatric patients through an open rhinoplasty approach followed by tip reconstruction and immediate fat grafting. A series of 3 pediatric patients presented with 1 to 1.5 cm nasal tip dermoid cysts that were causing distortion of the lower lateral cartilages. All 3 underwent excision of the cyst through an open rhinoplasty approach. The nasal tip was reconstructed with interdomal sutures and immediate fat grafting. Fat grafts were harvested from the abdominal wall and implanted in the nasal tip. The grafts filled the resulting dead space and were secured with the fibrin glue. The soft tissue was redraped, and the skin was closed. The final postoperative result, 2 years after surgical intervention, included a well-proportioned and appropriately shaped nasal tip without obvious incisional scars in all patients. The skin overlying the previously excised dermoid cyst was supple and healthy. Excision of nasal tip dermoid cysts in pediatric patients can be approached through an open rhinoplasty approach, tip reconstruction, and immediate fat grafting. This approach can provide assistance in correcting contour deformities and may help preserve an at-risk soft-tissue envelope.
