Experience with 78 Cases with Preauricular Sinus and 28 Cases

with Preauricular Skin Tag

Preauricular sinus and preauricular skin tag are common childhood congenital anomalies. It is important for the pediatric surgeon to be familiar with the embryology and differentiation of head and neck structure to accurately diagnose and treat these lesions. Seventy

eight patients with preauricular sinus and twenty-eight with preauricular skin tag treated in the Department of Pediatric Surgery at Hanyang University Hospital from January 1981 to May 2002 were reviewed to determine relative frequency, clinical classification and appropri

ate treatment. The male to female ratio of preauricular sinus was 1: 1.2, and preauricular skin tag was 1: 1. The most commonly presenting age of sinus and skin tag was before 5 year (62.8 %) and before 1 year (53.6 %). Twenty nine of 78 cases of preauricular sinuses were on

the left, 25 on the right and 24 bilateral. Signs of infection were seen in 73.0 % of patients with preauricular sinus at operation. Only 31.3 % of lesions were infected in patients less than one year of age, but 89.5 % between 3-5 years and 100 % between 5-8 years. Cartilage

was present in five patients with preauricular skin tag. Although re-operation due to wound infection was necessary in four cases, no recurrences were found. The preauricular sinus is a common anomaly in childhood, and has had a relatively high recurrence rate. But most of

the recurrences were due to incomplete resection because of combined infection. Initial proper diagnosis and early operation are very important. Identification of the exact anatomical location of sinus tract is necessary because total excision of the lesions including

those tracts is the only way to prevent recurrence. (J Kor Assoc Pediatr Surg 9(1):1 ~5), 2003.
