ABSTRACT
Preauricular sinus is a congenital abnormality in the form of a cyst or fistula that occurs in the preauricular soft tissue. Preauricular sinus is usually asymptomatic, but it is very susceptible to infection that causes preauricular sinus abscess. One of the conditions that can worsen preauricular sinus abscess is diabetes mellitus. In DM patients, there can be a decrease in immune response function which can worsen the infection. This a case of a 54-year-old male patient came with swelling in the right ear accompanied by pain and fluctuating fever. The patient has a history of uncontrolled DM. During the examination, edema, hyperemia, tenderness and smelly pus were found in the earlobe and laboratory findings showed leukocytosis (23.94 x 103/µL) and hyperglycemia (285 mg/dL). The treatment given to the patient was in the form of excision and extirpation of the preauricular sinus and drainage incision of abscess and medication. After treatment, the infection subsided and the patient's condition improved. The occurrence of preauricular abscess extending to the post auricular is rare, the risk factor that may cause the infection to spread is because the patient has uncontrolled diabetes mellitus comorbidities. Management of preauricular abscess consists of performing excision of the preauricular sinus and incision of abscess drainage as well as administering antibiotics, analgesics and steroids to treat infection, prevent complications and recurrence.
