Combined underwater endoscopic and microscopic surgery for tympanic paraganglioma: A case report.
The resection of middle ear paragangliomas can be challenging given their vascular nature and the small volume of the tympanic cavity, particularly when the tumor in the hypotympanum is close or attached to the internal carotid artery (ICA). We performed combined underwater endoscopic and microscopic surgery for a Class B1 middle ear paraganglioma according to the modified Fisch classification. The suspicious bone in the hypotympanum and around the petrous ICA was drilled with underwater endoscopy. The feeding arteries, the caroticotympanic and inferior tympanic arteries, were suctioned and cauterized under microscopy. To the best of our knowledge, no case of middle ear paraganglioma treated with underwater endoscopy has been reported. Underwater endoscopy, providing a clear operative field with blood and bone dust irrigation, is a good indication for middle ear paragangliomas. In contrast, microscopic preparation for unexpected bleeding is important, particularly when the tumor closely extends to vital structures, such as the ICA or the jugular bulb.
