متن کاملEndoscopic excision of a tympanic paraganglioma: Training the next generation of ear surgeons
Tympanic paragangliomas are uncommon vascular tumors of neural crest origin. Classically these lesions have been surgically managed via a transcanal or transmastoid approach using binocular microscopy. We describe a case in which a tympanic paraganglioma was removed via a transcanal approach, using the endoscope exclusively. Endoscopic ear surgery enhances visualization, helping to ensure compl...

Precise diagnosis is important in order to optimize patient treatment. Diagnosis relies mostly on histopathologic examination followed by immunohistochemistry. Here we report a 77-year-old woman wi...
