Intraoperative injection of combined fibrin sealant and methylene blue dye for surgery of branchial cleft cysts: A case report

Abstract

© 2019 Elsevier Masson SAS Differential diagnosis of a lateral neck mass, especially in paediatric patients, should include branchial cleft cysts (BrCC). It is often difficult to identify and completely resect all cystic components, especially when the lesion becomes infected and/or gigantic. Incomplete excision increases the likelihood of recurrences. We reported a simple technique to facilitate the BrCC resection. Tisseel fibrin glue (FG: Baxter AG, Vienna, Austria) was mixed with methylene blue dye in inverse portion to the cyst size and/or the FG volume before injecting into the cystic lumen. After polymerisation of the dyed glue, the lesion was better visualised and extirpated in toto with the aid of the dye colour and gelatinisation by FG. An up-to-date diagnostic and therapeutic algorithm for BrCC was also presented.
