title: Aberrant second branchial cleft fistula.
abstract: Second branchial cleft cysts and sinuses rarely present diagnostic problems to the pediatric otolaryngologist as their course is usually predictable based on consistent embryologic development. However, we evaluated two fistula tracts that did not fit the classic description of second branchial tract fistulas. Upon radiographic and intraoperative evaluation, their eventual course ending in the tonsillar fossa was identified. Realizing the potential for aberrancy and using preoperative radiographic evaluation will assist the surgeon in the excision of these developmental anomalies with little risk to underlying neurovascular structures.
