结局指标
主要结局
Rate of development of massive, semi-massive and large Keloids
时间窗: 1-5 years after surgery
Keloid Recurrence after surgery is a real-world outcome, one that takes time to develop. Study will intend to explore the long term rate of keloid recurrence after surgery. This rate will be reported as percentage of patients who undergo surgery and end up with developing a massive, semi-massive or large recurrent keloid
次要结局
- Rate of poor aesthetic outcome after ear surgery(1-5 years after surgery)
