Posterior group cranial nerve injury is a common postoperative complication of jugular venous bulbar tumor, which causes great pain to patients, especially multiple nerve injuries. Functional exercise after surgery is very important for the recovery or compensation of these nerves. The following are some methods of functional exercise that can promote rehabilitation and improve life treatment. Facial exercises: 1. Pronunciation training: pronounce “ah”, “yi”, “u” and “fu” in order. It may be inaccurate when pronouncing “Fu”, but try to be as accurate as possible, like whistling and blowing candles. Each sound ten times, three times a day. 2, facial muscle training: repeat the following actions several times, three times a day. (1) rhythmically frown. (2) open the mouth as wide as possible and then closed. (3) first puff up the cheeks, like blowing up a balloon shut up, puff up the cheeks, and then gently and slowly exhale. (4) shrink the cheeks: shut up and then inhale the cheeks into a depression-like. The above actions have time to do, do more and more repeatedly. Second, the tongue rehabilitation exercises: 1, outward tongue, and stretching in different directions up and down and left and right. Do it repeatedly. 2, roll up the tongue and then relax, do it repeatedly. Use the tongue to touch every corner of the mouth, up, down, left and right. Soft palate training: 1. Repeat the ‘ah’ sound loudly many times. 2. Inhale deeply and then hold your breath, paying attention to the part of the nasal cavity behind the force. Repeat several times. Four, throat muscle training: deep breath, hold your breath. Pay attention to the force parts in the larynx. Do more empty mouth swallowing action.
