Nasopharyngeal Branchial Cyst. These are congenital cysts often arising from the fossa of Rosenmüller located in the lateral wall of the nasopharynx. [4] [5] They represent remnants of first branchial cleft. These may extend superiorly to reach the bony confines of eustachian tube even to the skull base. [6]
Preauricular sinuses and preauricular cysts are two common congenital malformations. Each involves the external ear. The difference between them is that a cyst does not connect with the skin, but a sinus does. [3] Frequency of preauricular sinus differs depending the population: 0.1–0.9% in the US, 0.9% in the UK, and 4–10% in Asia and ...
