[First branchial cleft cyst in the parotid gland]

The authors have described genesis, localization and diagnosis of the first branchial cleft anomaly and the case of the branchial cyst in the deep parotid lobe. Surgical treatment (superficial parotidectomy and cyst extirpation from the superior part of the deep parotid lobe) was effective; one-year follow-up revealed no recurrence of the anomaly.
