Inflammatory Disorders

The inflammatory  Disorder process works quickly to destroy and eliminate foreign and damaged cells, and to isolate the infected or injured tissues from the rest of the body. Inflammatory disorders arise when inflammation becomes uncontrolled, and causes destruction of healthy tissue. There are dozens of inflammatory disorders. Many occur when the immune system mistakenly triggers inflammation in the absence of infection, such as inflammation of the joints in rheumatoid arthritis. Others result from a response to tissue injury or trauma but affect the entire body.

Perichondritis — It results from infection secondary to lacerations, haematoma or surgical incisions. It can result also from extension of infection from diffuse otitis externa or furuncle of the meatus. Pseudomonas and mixed flora are the common pathogens.

symptoms are red, hot and painful pinna which feels stiff. Later abscess may form between the cartilage and perichondrium with necrosis of cartilage as the cartilage survives only on the blood supply  from its perichondrium. treatment , in early satges, consist of systematic antibiotics. When abscess has formed, it must be drained promptly and culture and sensitivity of the pus obtained. Incision is made in the natural fold and devitalized cartilage removed.
