Listen to the check and diagnosis of nerve lump

Listen to nerve lump diagnosis a check
1, the pure sound measure to listen to present single side sound nerve deaf, the curve much declines a type for repeatedly abrupt Gao, minority is flat type or ascension type, from copy to measure to listen to the curve much accidentally sees a Ⅱ type for the Ⅲ and Ⅳ type, the sound Shuai becomes experiment great majority is masculine gender, the double ear alternately rings a degree balance with short increase the quantity sensitive index number experiment have no loudly degree heavy earthquake phenomenon, loudly the degree unwell Yu go up, the speech identifies a rate to obviously descend, much about 30%.The voice leads an anti- test:The drum room leads anti- diagram normal, the Deng bone muscle voice glint Yu goes up or disappears, the incubation period prolongs, and the often sick rational Shuai reduces.The ear Gua electricity diagram copies to record:If have no inner ear to provide a blood obstacle, the CM can keep normal, the AP wave obviously increases breadth, it responds that the Yu often more pure sound listens to Yu for low.Listen to sex brain stem inducting electric potential to copy to measure to show:Suffer from side Ⅴ wave incubation period and Ⅰ -Ⅴ wave to compare with Jian side, the period is obvious and prolong, even Ⅴ wave disappear, lately useful value of ⊿Ⅴ one who check to seek and listen to nerve lump, the accuracy is higher, clinical proof electric potential excrescent degree and lump body size is related.
2, the ex- court function check:Majority of patients can give or get an electric shock diagram to copy to record with the eye earthquake lateral the self-moving eye toward the Jian earthquake, various induct experiment respond widespreadly low, often have to suffer from lateral advantage to be partial to.
3, nervous system check, much have the Ⅴ , Ⅶ and Ⅸ , Ⅹ and ⅩⅡ brain nerve implicate of performance, the brain ridge liquid check egg white content goes up.
4, the image learn a check:The rock awl is each to project a X line even slice of or break 1 F film show to suffer from side inner ear a way extension, transform or have the bone wall the breakage, the inner ear way brain pond builds a shadow, CT and MRI not only can discover very small or don't get into the tumor of inner ear way, and can show the relation of the shape and surroundings organization of midstream, contribute to meninges lump, Dan fat lump etc. discriminates.
Diagnose:Much can confirm according to the typical model symptom and the check result, difficult early diagnose, also expensive early diagnose, need Be deaf to discriminate with the plum Ni Ai pathological changes with Tu.
