Outcome Measures

Primary Outcomes (1)

  • Rate of development of massive, semi-massive and large Keloids

    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

    1-5 years after surgery

Secondary Outcomes (1)

  • Rate of poor aesthetic outcome after ear surgery

    1-5 years after surgery
