Congenital Preauricular Fistula
ENTOverview
Congenital preauricular fistula is a congenital malformation left by abnormal auricular development during the embryonic period, with the opening usually located in front of the ascending limb of the helix. It is usually asymptomatic but causes local redness, pain, and purulent discharge when secondarily infected, with a tendency to recur.
Symptoms
- Small pit in front of the ear
- Local itching
- Discharge from the opening
- Recurrent redness and swelling
- Infection with pus discharge
Treatment
Asymptomatic cases need no treatment; control inflammation during infection, and surgically excise the fistula after inflammation subsides in recurrent cases.
Dietary advice
Eat a light diet, avoid spicy foods and seafood, and eat plenty of vitamin-rich fruits and vegetables.
