There is no consensus about the approach to these pathologies. The problem that makes surgery difficult is its possible proximity to vital vascular structures such as internal carotid in the deep plane and located laterally. We aimed to present our series of three patients who were diagnosed with nasopharyngeal branchial cyst and operated by transnasal endoscopic method by determining the safe surgical margin with the help of Doppler ultrasonography. Three male patients, who had various complaints such as difficulty breathing through the nose and sleep problems, were operated on with a transnasal endoscopic approach supported by 20MHz Doppler ultrasonography due to cystic formation in the nasopharynx. Histopathological evaluations were reported as a nasopharyngeal branchial cleft cyst. Doppler ultrasonography assisted transnasal endoscopic approach can be applied in the treatment. This approach both shortens the duration of surgery and minimizes the risk of neurovascular injury.eninfo:eu-repo/semantics/closedAccessdoppler ultrasonographynasopharyngeal branchial cleft cysttransnasal endoscopic approachA different perspective on the treatment of branchial cleft cysts, which are very rarely located in the nasopharynx: a case seriesEditorial564WOS:001376811400009Q4Q4
