It developed in nasopharyngeal bursa if opening of bursa is occluded due to infection or inflammation. It is rare congenital cyst present in nasopharyngeal bursa. Its incidence is 3% in adults [1]. The usual age of presentation is 2<sup>nd</sup> and 3<sup>rd</sup> decade [1]. It is usually asymptomatic and incidental finding on MRI but it can present as nasal obstruction, post nasal drip, halitosis, occipital headache, foreign body sensation in throat [1] [2]. Here we are presenting a case report of 23 years old male presented with foreign body sensation in throat since 5 months. On oral and nasal endoscopic examination cystic mass in nasopharynx seen, bulging in oropharynx. MRI shows cystic mass arising from left side of nasopharynx popping up in oropharynx. Cyst then excised with diode laser with both endonasal and transoral approach with zero degree rigid endoscope. Histopathology confirmed the cyst as thornwaldt cyst.展开更多
