Abstract:ObjectiveTo analyze and explore the clinical characteristics of glomus jugunlare tumor, summarize the surgery effect, and improve the experience of diagnosis and treatment of the disease.MethodsIt was retrospectively analyzed for the clinical data of 10 patients with glomus jugulare tumor confirmed by digital subtraction angiography (DSA) and/or postoperative pathology. The clinical features, imaging features, perioperative management, surgical methods and follow-up results of the disease were summarized.ResultsAll the cases were single ear involvement, including 8 females and 2 males. There were 6 cases of unilateral pulsatile tinnitus, 8 cases of hearing loss, 3 cases of earache and dizziness, 4 cases of discharge from the ear canal. And a case of ear canal mass was found by physical examination. In 6 cases, the tympanic membrane could not be seen due to the tumor protruding into the ear canal. In 4 cases, cherry red or dark red pulsation in the tympanic cavity could be seen through the tympanic membrane, and the tympanic membrane was slightly bulging outward. Pure tone audiometry showed conductive hearing loss in 4 cases, mixed hearing loss in 5 cases, and sensorineural hearing loss in 1 case. CT and MRI of temporal bone were performed in all cases. Tympanic body tumor showed the density of irregular soft tissue in the tympanum and external auditory canal; Glomus jugulare paraganlioma showed the density of soft tissue in the jugular foramen area, and the surrounding area showed "corroded" bone destruction and mass protruding to the tympanum and external auditory canal. The enhanced scan shows obvious enhancement. 3 cases of glomus jugulare paraganlioma underwent DSA examination and showed dense tumor staining in the jugular foramen area. 2 cases were supplied by the ascending pharyngeal artery, and 1 case was supplied by the ascending pharyngeal artery and occipital artery. All 6 patients with tympanic body tumor underwent retroauricular incision tumor resection, 3 patients with glomus jugulare paraganlioma underwent infratemporal fossa type A approach tumor resection, and 1 patient underwent gamma knife treatment. All cases followed up for 6 months to 5.5 years were no recurrence or serious complications affecting life.ConclusionGlomus jugulare tumors have their characteristic clinical features, most of which are unilateral pulsing tinnitus and different degrees of hearing loss. It is not difficult to diagnose with careful physical examination and image inspection. Patients with tympanic body tumor can achieve good results through middle ear surgery. Patients with glomus jugulare paraganlioma have high requirements for the surgeon and perioperative treatment due to their special anatomical position. The team is required to have knowledge and experience in lateral skull base surgery. Otherwise, it may easily lead to serious complications.
