Objective To review our experience with branchial cleft anomalies, with special attention to their subtypes and anatomical relationship to the facial nerve.
Study Design Case series.
Setting Tertiary care center.
Patients Ten patients who underwent resection for anomalies of the first branchial cleft, 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 branchial cleft anomaly was performed in all cases. Wide exposure of the facial nerve was achieved using a modified Blair incision and superficial parotidectomy. Facial nerve monitoring was used in every case.
Main Outcome Measures The primary outcome measurements were facial nerve function and incidence of recurrence after resection of the branchial cleft anomaly.
Results Ten patients, 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 facial nerve paresis or paralysis, and none of the patients has had a recurrence.
Conclusions The successful treatment of branchial cleft anomalies 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.
