Pharyngeal localizations of branchial cysts.

Two cases with unusual pharyngeal localizations of branchial cysts medial to the great neck vessels and pharyngeal constrictor muscle are presented. The authors reviewed the theories of origin of the branchial cysts and the surgical treatment options. In their first case the transoral approach was chosen. Because of previous unsuccessful attempts at surgical treatment, the pharyngeal cyst was extremely adherent to adjacent tissue with much scar tissue, and it was very difficult to remove. As a result of this disappointing operation, an external neck exploration was indicated in the second patient. Histological examinations confirmed that the excised cysts were branchial in both cases.
