ABSTRACT
OBJECTIVE: The goal of our study was to find an easy and suitable skin burn model for rabbits, to identify the temperature and contact time to reach a deep 2nd degree burn, and to find the best wound dressing fixation method. MATERIAL AND METHODS: We used New Zealand male rabbits as experimental models. On a pilot study, with a copper device heated to temperatures between 43-48 Celsius degrees, the burn was inflicted using contact timesof 3, 4, 5, and 7 seconds. The burn depth was evaluated histological. Twenty-four rabbits were used to evaluate four dressing fixation methods: regular dressing with retention bandages; skin stapler; collars and body resin cast. RESULTS: A 2nd degree deep burn was obtained at 43 degrees for 4 seconds. The retention elastic bandages were removed within hours and the skin staplers were removed with teeth leaving wounds on the skin. The collars were more successful but produced superficial neck lesions. The body resin casts were the most successful. CONCLUSIONS: The best contention method was the bpdy resin cast.

Ear keloids are among the most challenging plastic surgery conditions and may have significant psychosocial impact for the patient. Their aesthetic considerations are serious and despite a variety of treatment options, they often proved to be recurrent. This paper reviews the management options of ear keloids available in literature up to date. Multiple therapeutic options are discussed, such as: surgical treatment, corticosteroid injections, laser therapy, cryotherapy, radiotherapy, pressure therapy, therapy with antitumor or immunosuppressive agents.
