Two cases of nasopharyngeal branchial cleft cyst treated by powered instrument assisted marsupialisation

Objective:We report two extremely rare cases of symptomatic nasopharyngeal branchial cleft cyst treated by powered instrument assisted marsupialisation.Methods:Case report and literature review concerning nasopharyngeal branchial cleft cyst and surgical treatment methods.Results:The first case was a two-year-old boy with a 1 × 2 cm, cystic, oropharyngeal mass, who also had severe snoring and sleep apnoea. The second case was a 56-year-old man with right nasal obstruction and a sensation of fullness in the right ear. In both cases, we performed endoscopic marsupialisation using a powered instrument. There was no recurrence in either case over two years of follow up.Conclusion:Powered instrument marsupialisation is a simple, effective and less invasive technique for the treatment of nasopharyngeal branchial cleft cyst.
