Non-pheochromocytoma resection

Glomus jugulare tumors are also known as nonchromaffin paraganglioma or chemical receptor tumors and tympanic body tumors. The jugular vein is the same tiny tissue structure as the carotid body or aorta, about 0.5mm × 0.5mm × 0.25mm, flat or oval, often one, occasionally more than two, how long At the adventitia of the jugular vein, or along the glossopharyngeal and vagus nerves to the tympanic cavity or in the middle ear, mucous membranes and bones. Its function is similar to that of the arteries, and it has a sensitive effect on the partial pressure of oxygen and carbon dioxide. It may also be related to some kind of endocrine. Tumor growth is mainly based on anatomical channels, such as jugular foramen, external auditory canal, etc., can also invade Haval bone tube to destroy bone and oppress adjacent tissues, nerves and so on. The growth rate can be fast or slow. Tumor-like vascular granulation tissue, no obvious capsule, slightly nodular or lobulated, tumor blood vessels are extremely rich, blood vessel wall has no contraction function, and it is easy to bleed. Treatment of diseases: jugular bulbar tumor Indication Non-chromophobic paraganglioma resection is suitable for tympanic tumors that are confined to the sacral, lower tympanic or tympanic papillae (stages A and B). Contraindications The tumor extends beyond the tympanic mastoid area and invades the facial nerve or pyramid. Preoperative preparation 1. Learn more about the condition, such as typical pulsating tinnitus. 2. X-ray plain film, tomogram, CT and MRI examination were performed to confirm that the tumor was confined to the tympanic papilla region. 3. 1d preoperative shaving is the same as middle ear mastoid surgery. 4. Perform routine hematuria, clotting time, liver and kidney function tests, and cardiopulmonary function tests. 5. Procaine and penicillin skin allergy test. Surgical procedure 1. The incision is confined to the tympanic cavity to take the incision in the ear, and the incision is made after the tumor invades the mastoid. 2. The tympanic type separates the external auditory canal flap and opens the tympanic cavity to remove the tumor. 3. The tympanic mastoid type is drilled on the surface of the mastoid to remove the wall into the mastoid, remove the posterior wall of the external auditory canal, form the mastoid root cavity, remove the tumor, and protect the facial nerve. 4. Complete hemostasis, tympanoplasty is performed on conditional conditions; unconditional patients form a mastoid root cavity, intraluminal skin grafting, suture incision with iodoform gauze, and dressing. 5. If the tumor is mainly in the jugular bulb, sigmoid sinus ligation and internal jugular vein ligation should be performed, and the tumor should be removed together with the jugular bulb. The sinus ostium of the rock is filled with muscle blocks. complication Intraoperative may damage the facial nerve and the structure of the middle ear and inner ear, causing facial paralysis, dizziness and deafness.
