M. Ellies et al., CLINICAL-EVALUATION AND SURGICAL-MANAGEMENT OF CONGENITAL PREAURICULAR FISTULAS, Journal of oral and maxillofacial surgery, 56(7), 1998, pp. 827-830
Purpose: The retrospective investigation evaluated the clinical data o
n patients with a preauricular fistula with respect to demographic fac
tors, symptoms, preoperative diagnosis, and surgical therapy. Follow-u
p studies served to critically assess the outcome of the operations. P
atients and Methods: The records of 62 patients were studied. Patients
were divided into two groups: those operated on for the first time fo
r a preauricular fistula and those operated on for a recurrence. Contr
olled follow-up was performed by means of a standardized questionnaire
filled out by both the patients' physicians and the patients themselv
es. Results: The mean age of patients operated on for the first time w
as 16 years, and that of patients operated on for a recurrence was 22
years. Although the overall rate of recurrence was 21%, it differed wi
dely between groups (14% in first operations and 42% in patients opera
ted on for the first time for a recurrence). These figures are within
the lower range of the recurrence rates previously reported. Serious s
ide effects, such as persistent damage to the facial nerve, were not o
bserved. Conclusions: Operative management of a preauricular fistula i
s a treatment with few side effects that should be offered to each pat
ient with such a malformation. Because the first operation is decisive
for the further course of the condition, surgery should be performed
under optimum conditions to avoid recurrence.
