Abstract
The Frequency of Underlying Causes and Required Surgical Interventions in Patients withExternal Ear Chondritis in south west of Iran
Highlights
Perichondritis is acute inflammation of the skin and perichondrium that involves the cartilage of the ear stems
A checklist was designed, including age, sex, duration of hospitalization, the need for surger y, antibiotics prescribed duringhospitalization, etiologies of the disease, including diabetes, burns, external otitis, blunt trauma, immune deficiency, and history of previous surgeries, including mastoidectomy, piercingtheearcartilage, laceration,and suturing theears and informationwas recordedinchecklists andfor analysis, descriptive statistical methods, including frequency tables, graphs, and numerical indicators were used to describe variables and chi-square test and logistic regression were usedfor the association between variables
The mean age of patients was 29.8 years. 53.7% of patients were in the age range of 11-30 years. 66.2% of the patients were men and 33.8% women
Summary
Perichondritis is acute inflammation of the skin and perichondrium that involves the cartilage of the ear stems. The changes are limitedand do not proceed beyond the ear cartilage border. In case of cartilage involvement, chondritis will occur[1]. Earhas a very special anatomy and its skin is directly connected to perichondrium and the cartilage is very vulnerable to injuries[6,16,17]. Common organisms include Staphylococcus aureus and Pseudomonasstrains. In cases of blunt trauma, a hematoma can be formed in the external surface of the ear in the beginning due to infection, such as wrestlers. Penetrating trauma may be due to different injuries, including ear piercing, needle, bites, wounds without a reason (unknown), thermal or chemical burns, and after some surgeries (Mastoidectomy).
