Latter, 3 rich of Beijing revive cerebral division hospital receives the child that treated much name to come round to see a doctor because of change of eyesight, eye shot, manage tumor for skull pharynx via checking diagnose. According to this courtyard expert Shi Xiangen teachs the introduction, skull pharynx is in charge of tumour to be common disease in cerebral surgery, although this tumour occupies the 6.5 ％ of 4.7 ％ ～ of the tumour inside all skull only. Among them, great majority patient is 15 years old of the following children, especially 8 ～ are in the majority 12 years old.

Tumour of skull pharynx canal is a kind of benign congenital tumor, it is important that Dan Jisheng grows head of the grave below constant drag in structure, reason needs complete excision, lest affect the patient's growth development. Regretful is, because the parent or medical personnel of specialized subject of a few blame lack relevant knowledge, make the little patient sees a doctor too late or cannot receive effective treatment. After if become a little patient,eyesight is damaged badly, although open skull operation to excise tumor all right, the harm of eyesight also cannot restore completely, even blindness.

Because tumour of skull pharynx canal is in place, grow those who develop direction and patient age is speed, different, its are clinical expression also differs somewhat, but in general, 5 big symptoms are the signal that is worth vigilance under:

　 One, change of eyesight eye shot

Head with obstacle of eyesight eye shot the person that send a symptom is not scarce, the 80 ％ of 60 ％ ～ that occupy skull pharynx to manage tumor about are controlled. Because tumor is right visual access is oppressive of place different, clinical on expression is short of caustic for different view. Because inspect alternate press press, appear double Nie side (the two side outside the eye) slant blind, a side inspects bundle of press press to be able to arise to slant with tropism blind (namely outside side sex blind and another inside sex blind) , optic nerve of oppressive a side can produce monocular eyesight to drop or blindness. When cannot narrate eye shot circumstance sometimes as a result of children or be being checked uncooperative, often determine hard the change circumstance of its eye shot.

　　 2, heighten of skull internal pressure

This kind of circumstance sees at children skull pharynx manages tumor more, can head hair symptom, because system of tumor block ventricle causes hydrocephalus, head to press elevatory be caused by,this basically is. In clinical on expression is have a headache, oedema of tit of disgusting vomiting, optic nerve, diplopia and neck are painful etc. The person that infant and partial children come on, can skull seams fission, the head increases, kowtow show " broken crock " sound. Almost all patient has have a headache, head for the most part hair symptom, much companion has vomiting.

　　 3, endocrine is disorder

Disorder symptom of occurrence endocrine of the person that the 2/3 in tumour patient is in charge of in skull pharynx, the leaf before much make water and hypophysis stimulates the fights diuresis hormone to lack generation much drink of the leaf after including pituitary body among them the growth that element lack produces is deferred, runty. If be adult patient, function of meeting occurrence sex drops. In the male expression is sexual desire low, impotent, patient skin is fine thin, lack of power, sound is taper, adult beard is exiguous wait; The person that male adolescent comes on, sexual organs but not development, lack of secondary sex characteristic. Expression of adult woman patient spends period to never have or stop classics.

　　 4, consciousness changes

Obstacle of partial patient occurrence consciousness, expression is dim or be addicted to sleeps, minority can appear insensible. Because grave head bottom is damaged,this may be, the happening that because the head is hernial,reachs causes place of midbrain press press to cause.

　　 5, change of optic nerve tit

As a result of heighten of skull internal pressure, oedema of tit of patient occurrence optic nerve, with the passing of time produces optic atrophy, eyesight drops down to blindness. Tumor oppresses optic nerve produces the former optic atrophy that send a gender directly. Individual patient inspects a tit but normal.

The child has above show, the parent should take his to be checked to conditional hospital as soon as possible, so that diagnose. Current, coronal CT and MRI (magnetism resonance) it is the most advanced, simple, and the most accurate examination instrument. To this ill cure, professor Shi Xiangen emphasizes saying, the operation is current first selection method. In recent years, in hospital of good in the condition professional brain surgery, microscopical and surgical technology had great progress, can utmost protects nerve organization, make an operation more safe.

The structure such as the area that resection of tumour of skull pharynx canal involves is densely covered important nerve, blood-vessel, it is the difficulty of neurosurgery, outside because this doctor is divided,having relevant anatomy knowledge, extensive nerve endocrinology knowledge, still must possess skilled operation skill, stable psychological quality, such ability make sure the operation is successful.
