Retrospective Study of Keloid Disorder

October 1, 2016 updated by: Tirgan, Michael H., M.D.
Purpose of this retrospective study is to review and analyze the information and data that has been already been generated during the course of routine practice of medicine by the investigators from 2007 up until Sept 1, 2016 from keloid patients who have sought medical care or medical advice for their keloid disorder.

Study Overview

Detailed Description

To retrospectively review and analyze clinical data that has already been collected from keloid patients including photographs taken of keloid lesions during routine practice of medicine by the investigators 1) To better understand natural history of keloid disorder (KD), 2)To determine the ethnic incidence and prevalence of keloid, 3) To determine the rate of familial keloids, 4) To determine response to different treatment modalities, 5) To determine risk factors for development and worsening of keloid lesions.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Rate of development of massive, semi-massive and large Keloids
Time Frame: 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
1-5 years after surgery

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Rate of poor aesthetic outcome after ear surgery
Time Frame: 1-5 years after surgery
Surgical intervention often results in loss of ear tissue and poor aesthetic outcome. Although fully expected, the actual rates of this outcome is unknown. Study intends to report the actual rate of disfigurement and poor aesthetic outcome after ear surgery for removal of keloid lesions.
1-5 years after surgery
