Pressure therapy was popularized in the 1970s after clinicians noticed that pressure stockings used over lower extremity burns caused scars to mature faster with decreased erythema and thickness. Pressure causes localized hypoxia, resulting in fibroblast degeneration and disintegration owing to decreased intercollagenous cohesion and increased collagenase activity.Furthermore, pressure has been shown to shorten scar formation time, reorient collagen fibers within the scar to become parallel to skin surface, increase hyaluronic acid levels, and decrease chondroitin sulfate levels, all of which help to flatten the initially elevated scar tissue and reduce recurrence rates.According to various reviews and guidelines, pressure therapy is a long-standing therapeutic option for keloids, producing thinning and pliability. Although the precise biomolecular mechanism of compression is not understood, success rates of at least a partial reduction of derailed scars, from 60% to 85%, have been reported from a monotherapeutic regimen of pressure therapy. The combination of surgery with postoperative pressure treatment showed good response rates of about 90% to 100%, especially after excision of auricular keloids. ………Overnight use of the new pressure device seems to be an effective extension of established auricular keloid therapy, with additional potential for prophylaxis of recurrence. Preliminary work was presented and intended to produce a demonstration of an optimized treatment modality. Analysis of this therapeutic regimen based on a larger sample size, and long-term follow-up will be the substance of a future report.

Updated 3/2017-- photos and all links (except to my own posts) removed as many no longer active.
I have written of keloid treatment (general, not site specific) previously. I have always tried to include pressure treatment as part of the plan when treating keloids of the ear lobe. This pressure treatment came in the form of pressure earrings -- clip-on, disc-shaped.
The recent article (full reference below) in the Archives of Facial Plastic Surgery journal introduces a new pressure device which looks like it will work better than what has been available (photo credit)
and as can be seen in this photo the upper ear can be treated with pressure which has not been possible with the clip earrings. (photo credit)
These devices were custom made which makes them more expensive than off-the-shelve pressure earrings and may make them difficult to get if no one is available in your area to make them.
