OBJECTIVE: To review our experience with @entity5816 , with special attention to their subtypes and anatomical relationship to the facial nerve. STUDY DESIGN: Case series. SETTING: Tertiary care center. @entity1 : Ten @entity1 who underwent resection for anomalies of the first @entity2419 , with at least 1 year of follow-up, were included in the study. The data from all cases were collected in a prospective fashion, including immediate postoperative diagrams. INTERVENTION: Complete resection of the @entity5816 was performed in all cases. Wide exposure of the facial nerve was achieved using a modified Blair incision and superficial parotidectomy. @entity2103 monitoring was used in every case. MAIN OUTCOME MEASURES: The primary outcome measurements were @entity2103 and incidence of recurrence after resection of the @entity5816 . RESULTS: Ten @entity1 , 6 females and 4 males,with a mean age of 9 years at presentation, were treated by the senior author (P.J.K.) between 1989 and 2001. The lesions were characterized as sinus tracts (n = 5), fistulous tracts (n = 3), and cysts (n = 2). Seven lesions were medial to the facial nerve, 2 were lateral to the facial nerve, and 1 was between branches of the facial nerve. There were no complications related to @entity2103 or @entity912 , and none of the @entity1 has had a recurrence. CONCLUSIONS: The successful treatment of @entity5816 requires a complete resection. A safe complete resection requires a full exposure of the facial nerve, as the lesions can be variably associated with the nerve.
