How about the pterygoid canal neurotomy?

summary

Everyone has heard that the better treatment for allergic rhinitis is the pterygoid canal neurotomy. The principle of pterygoid nerve resection is to remove the parasympathetic nerve in the nose, so that the blood vessels in the nasal cavity and sinuses are in a state of contraction, and the secretion of nasal secretion and lacrimal gland is greatly reduced. After removal of the pterygoid canal nerve, the edema of the lamina propria of nasal epithelial cells was alleviated, the epithelium also returned to the pseudo stratified state, the eosinophils disappeared, and the degranulation of mast cells decreased. How about the pterygoid canal neurotomy? Now let me tell you something.

How about the pterygoid canal neurotomy?

Before the pterygoid canal neurotomy, the operation must be prepared according to the nasal cavity and maxillary sinus. For example, trim nose hair, nasal routine medication according to allergic rhinitis. There is, such as nasal polyps should be taken before nasal film, we must understand the development and inflammation of nasal sinuses and so on.

In addition, if the posterior end of the middle turbinate is hypertrophic during transnasal surgery, the part of the middle turbinate should be removed to make the field clear. When entering the pterygopalatine fossa, attention should be paid to prevent the sphenopalatine artery from bleeding, ligation or blocking the blood flow with silver clips. Do not damage sphenopalatine ganglion or maxillary nerve.

Because it is easy to enter the sphenoid sinus or posterior ethmoid sinus by mistake, it will bring some difficulties to the operation. We must find the funnel-shaped opening of the pterygoid canal along the upper part of the posterior nostril and the lower part of the sphenoid sinus. If the electric coagulation of pterygoid nerve should not be too deep, to avoid causing extraocular muscle paralysis.

matters needing attention

The above is a brief introduction of pterygoid canal neurotomy. Although pterygoid canal neurotomy is more effective for rhinitis, because it is an operation, it is only recommended on the basis of completely ineffective use of drugs.
