Untreated branchial cleft cyst lesions are prone to recurrent infection and abscess formation with resultant scar formation and possible compromise to local structures.

Complications of surgical excision of branchial cleft cysts result from damage to nearby vascular or neural structures, which include carotid vessels and the facial, hypoglossal, vagus, and lingual nerves.

There are rare case reports of malignancies having been identified in branchial cleft lesions, including branchiogenic carcinoma and papillary thyroid carcinoma.
