Transcanal Endoscopic excision of tympanic paraganglioma, a report of our surgical technique

Abstract

Paraganglioma is the commonest middle ear tumor and the 2nd most common temporal bone tumor after vestibular schwannoma. Different classification systems have been proposed based on the extension of the tumor. Diagnosis is based on both clinical and radiological features. CT is valuable in defining the extension of the lesion and excluding erosion of the jugular bony plate. Endoscopic excision of these tumors has been described in the early 2010s. We report a case of female patient 40-years-old with right tympanic paraganglioma extending to the protympanum and hypotympanum. Exclusive transcanal endoscopic excision was performed.
