Summary
Two unusual second branchial cleft fistulas were identified ending in the tonsillar fossa. Preoperative imaging is crucial for surgical planning and safe excision of these rare pediatric neck anomalies.
Area of Science:
- Pediatric Otolaryngology
- Developmental Biology
- Surgical Anatomy
Background:
- Second branchial cleft cysts and sinuses typically follow predictable embryologic pathways.
- Diagnosis is usually straightforward for pediatric otolaryngologists.
- Classic presentations aid in surgical planning and management.
Observation:
- Two cases of second branchial cleft fistulas presented with atypical anatomy.
- The fistula tracts did not conform to the typical description.
- Radiographic and intraoperative findings revealed an unusual course ending in the tonsillar fossa.
Findings:
- The aberrant course of these second branchial cleft fistulas was identified through detailed evaluation.
- Preoperative radiographic assessment is vital for understanding the anomaly's extent.
- Intraoperative findings confirmed the unique pathway to the tonsillar fossa.
Implications:
- Recognizing potential aberrancy in branchial cleft anomalies is essential.
- Preoperative imaging assists surgeons in planning complex excisions.
- Careful surgical planning minimizes risks to adjacent neurovascular structures during removal.
