The styloid syndrome is a general term for symptoms such as pharyngeal foreign body sensation, pharyngalgia or reflex aural pain, head and neck pain, salivary gland and the like caused by long styloid process (more than 2.5 cm) or abnormal stimulation of adjacent vascular nerves due to azimuth and morphology. Is common in adults. The onset is slow, the medical history is different, the pain of tonsil area and tongue root area is usually single-sided, the pain is not severe, and the pain can radiate to ears or necks and aggravate when swallowing. Foreign body sensation or obstruction in the pharynx is more common, mostly on one side, more obvious when swallowing, and sometimes aggravated during speaking, turning around or at night. Cough can also be caused, pain can radiate upward from one side of the mandibular angle to the head, neck or face when the carotid artery is compressed or rubbed.

The sliding sleeve 8 is slid to the bottom (the positioning block) so as to peel off the tissues on the styloid process 10. The sliding sleeve 8 can be pulled out after one stripping, the rope loop is tightened again, and the rope loop is reeved in the direction until the tissue is stripped cleanly. The pull cord 34 maintains the balance of the loop and also prevents the loop from being pulled off the cord lock 33 when the movable end 32 is pulled.
After tissue stripping is finished, the position of the external thread sleeve 3 can be adjusted, the screwing depth can be determined according to the cutting position, namely, the positioning baffle at the lower end of the external thread sleeve 3 is arranged slightly below the cutting position, and the operation is guided by the visual operation of the endoscope system. Then the rotary sleeve 4 is put into the external thread sleeve 3, and the cutting blade is spread by the knob 10 in the putting process. The rotary sleeve 4 is driven to rotate by the driving rod 6, so that the cutting blade 5 is driven to cut the styloid process 10. The two cutting blades 5 have better matching use effect. The truncated styloid process falls above the cutting blade 5, which is convenient for direct taking out and avoids residue in the body.
The application truncates the temporal bone styloid process by cutting off the styloid process to replace the existing breaking mode, and has small wound and controllable truncating length. For protection of the sleeve, the surrounding tissue may also be protected from unnecessary damage. The whole operation process is greatly simplified, and the number of the operators involved is reduced from three to one.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that the above-mentioned preferred embodiment should not be construed as limiting the invention, and the scope of the invention should be defined by the appended claims. It will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the spirit and scope of the invention, and such modifications and adaptations are intended to be comprehended within the scope of the invention.
