Acoustic neuroma surgery of the facial nerve problems
Grasp the anatomical landmark surgery, the long way approach offers the advantages of anatomic landmark identification of the facial nerve, facial nerve function and therefore save the route better than the other. Into the vestibule after the labyrinthectomy, you can see the oval recess cribriform vestibular area,[link widoczny dla zalogowanych], the common white point of a number of vestibular nerve endings into the office, in this mill is the opening of the lateral end of the internal auditory Xiao. The internal auditory canal opened, showing the vestibular nerve, the former court between nerve and facial nerve has a vertical ridge, eating in front of the vertical is the facial nerve. Vertical ridge is clearly by the translabyrinthine approach an important symbol of the facial nerve. Find the vertical crest, the facial nerve would not be drawn into the tumor to go:. Proper use of the drill in the labyrinthectomy is necessary to prevent injury of the facial nerve in the side, trapped for the posterior semicircular canal ampulla in the facial nerve in the vertical section of the inner surface, and in lateral semicircular canal ampulla in the facial nerve in the knee and the horizontal segment of the Oh 【, in the When exposed to vestibular, drill the inside of the facial nerve in the operation. Also outlined the contours of the nerve to come forward, grinding Thin neural tube on the exposed bone and internal auditory canal lateral vestibular end is very important,[link widoczny dla zalogowanych], operation, use the diamond bit and drill bit on the side to see clearly the surface of grinding bone. In addition to the mill to hear the aisle wall and the middle cranial fossa bone between the brain plate pairs, to avoid the injury section of the facial nerve within the auditory canal, because the facial nerve located in the meninges under the internal auditory canal, internal auditory canal drill slide can damage the facial nerve. Diamond bits to be applied, and note the direction of bit rotation. Bone edge of the storm, including sharp edges of the auditory canal just above the drill bit is easy to slip into the internal auditory canal, in order to avoid the possibility of such a sliding drill, drill bit from the middle cranial fossa meningeal move inward aspects of hearing, requires the bit along the left ear clockwise rotation, the right ear requires drill counterclockwise rotation. 3. Correct application of hemostatic removal of acoustic neuroma cancer side hanging process, we must always pay attention to hemostasis. To prevent postoperative complications, but sometimes small blood vessels into the facial nerve i: and a branch to the tumor surface, affect the separation of the facial nerve,[link widoczny dla zalogowanych], then used cotton balls to small blood vessels open, and there is hemostasis role in the facial nerve not the best around bipolar coagulation, due to the heat generated may damage the operation of the facial nerve fibers arising from facial paralysis. (December 21,[link widoczny dla zalogowanych], 1987 Received 088 on September 16 either back) jets and a case of nasopharyngeal plasmacytoma Ninth Hospital of PLA, Shenyang National Otolaryngology side of our department have come larynx, nasopharynx plasma cells tumor, after surgical removal, followed up for 2 years, 8 months without recurrence and metastasis jl, male patients are reported as follows, 55 years old. Won progressive hoarseness and right suction Yi resistance of more than 7 years who dyspnea 3 days in 1985】 2I7 [J third time into the Ju. Outside the hospital has been in cricothyroid membrane puncture, transferred hospital after tracheotomy. After fiberoptic examination, see the right nostril 2cm diameter mass, Qiu uneven surface contamination. Epiglottis laryngeal surface of the right have I_5cm diameter spherical masses. Smooth surface. Base broad, scoop asked supraglottic 2.5cm diameter spherical tumor area with smooth, throat, larynx anteroposterior radiographs showed a d × 3,5 cm soft shadow New York organization, this week's no protein in the feces, bone marrow normal. Hospital in January 1986 after 2,1 day to enjoy open laryngeal tumor. R see the left side of throat surgery room fighting mass 3 × 2.5 × 2.5cm, epiglottis laryngeal surface of mass 2 × 1.5 × 1.0cm. Postoperative left vocal cord paralysis in paramedian position fixed. February}] hard-cut path operation, see Shun-hole right after the 3 × 3 × 2.5cm mass Asr management report for the larynx, nasopharynx Cave plasma cells (1.2 laps). After 2 years 8 months after surgery, {with the defense. Blocks smooth throat wound, left vocal cord paralysis without metastasis are rare Midship plasmacytoma cancer occur in the nasopharynx, nasal cavity, Yi Dou, mouth drying, the occurrence of saddle-less dry throat. A good age of 50 to 70 years, more men than women, mostly solitary, few are more dominant. The slow progress of the disease course of 7 years of this side of the owl. Seen by the eye from the class of interest, such as fiber type, quality,[link widoczny dla zalogowanych], there is calm and the hardness of starch block beech material increases, clinical symptoms without beads, should be within the nose, throat interest rates} uniform identification. Interestingly, the pathological diagnosis of plasma cell cancer microscopic Stem swelling seen in plasma cells by numerous friends, may be associated with amyloid calm. ': On the nature of plasma cell tumors, said Hao mixed, most scholars believe to be benign. But the possibility of malignancy; some swelling that is the Cave of the pit boundary of the soft tissue side of the plasma cells are of primary cancer. Extramedullary plasmacytoma and plasma cell tumors of intramedullary interlocking distinction is often elevated serum gamma globulin, rhino appears in the monopoly of wisdom's protein. And no extramedullary, two had very different prognosis and vertical, but the cell morphology is essentially the question. Extramedullary plasmacytoma can be made for the intramedullary plasmacytoma stern extramedullary plasmacytoma is likely to be small cancer of plasma cells within the tumor of the blue a local table management.
