The exposed and projecting auricular conchas are easy to be injured. The skin and subcutaneous tissue of external ear are thin, so ear burn always compromises auricular cartilage. 

Besides, since it was near hair and was connected with external auditory canals, and ears themselves were too irregular and rough to be cleaned, ear burn was usually complicated with infections and suppurative perichondritis of auricle post injured.
 
Traditional MEBT for treating ear burn has disadvantages that the ointment on the wounds is easy to be wiped off by external objects, especially when the sick children are unwilling to cooperate for drug application, which seriously impacts the curative effect of MEBO.

Furthermore, because ear burn is usually accompanied with more serious burn wounds in other parts, such as eye burn or respiratory tracts burn, the treatment and nursing to the ears burn is usually ignored by medical staff and relatives of the patients.
 
An updated method in treating ear burn involves the application of MEBO gauze, which ideally prevented perichondritis of auricle without the prohibition of medical conditions and had the advantages of convenient operation and easy controlling. 

Moreover, treated with this therapy, the wounds could heal soon with little scar.

MEBO gauze has the following characteristics in treating purulent perichondritis of auricle: 

1. Ideal analgesic effect.

2. General antibiotic was used instead of massive-dose broad-spectrum and high-grade antibiotic. 

3. To some extent, it could reduce the pain when the patients receive the excisions of necrotic cartilage under systemic anesthesia, and the rate of deformity healing.
