ABSTRACT
The article describes a clinical observation of a 17-year-old patient with an advanced tumor of the endolymphatic sac in the direction of the middle and posterior cranial fossae, the internal auditory meatus, and the cerebellopontine angle. After selective embolization of tumor afferent vessels, a combined transmastoid, translabyrinthine, and extended approach through the middle cranial fossa was used. The facial nerve is preserved along its entire length. The inferior cranial nerves remained intact when the mass was removed from the jugular foramen. Resection of the lower part of the tumor together with the sigmoid sinus, endolymphatic sac, and bulb of the jugular vein was performed after tamponade of the transverse and inferior petrosal sinus. The structure of the upper part of the tumor included: mastoid process, antrum, and tegmen tympani, which were resected after coagulation of the middle meningeal artery. The petrous part of the tumor was removed after preservation and mobilization of the internal carotid artery and visualization of the third (mandibular) branch of the trigeminal nerve. Repair of the bones of the base of the middle cranial fossa was carried out using the Medpor material. The postoperative cavity was obliterated with abdominal fat, and the external auditory meatus was tightly sutured using the cul-de-sac technique.
