Oropharyngeal paraganglioma presenting with stridor: an unusual presentation

Abstract

Head and neck paraganglioma is a rare disease to encounter in clinical practice and involvement of the base of the tongue in the oropharynx is yet to be described in the current literature. Although various surgical approaches have been described in the literature, transcervical mandibular swing is an effective technique for adequate exposure and complete excision of the oropharyngeal paraganglioma with adequate control on bleeding especially when it is assisted by coblation.

[1][2][3] This patient complained only of the painless, non-tender mass below the angle of the mandible.…”

“…6) In the head and neck region, it occurs mainly in the temporal bone, jugular foramen, vagus nerve, or carotid body. 3,4,6) Herein, we report a case of paraganglioma of the submandibular region that has not been reported.…”

“…[1][2][3][4][5][6][7] Paraganglioma is most common in the abdomen, followed by the chest and head and neck. 2,3,6) Paraganglioma accounts for 0.6% of the all the benign tumors affecting the head and neck region. 3) Head and neck paraganglioma is usually slow growing and non-secretory.…”
