Zygomatic fracture of upper row of teeth without sensation is mainly caused by the fracture tip, hematoma or inflammatory substances affecting the normal function of the trigeminal nerve and leading to loss of sensation of the teeth.
1. Zygomatic bone fracture may damage the trigeminal nerve which is distributed near the fracture, and the trigeminal nerve controls the sensory function of the teeth, so the damage to the trigeminal nerve will lead to the numbness and loss of sensation of the maxillary teeth.
2. Zygomatic bone fracture can cause bleeding from deep trauma of soft tissues in the maxillofacial area, and the hematoma formed by blood coagulation will compress the nearby trigeminal nerve, which will also cause the appearance of the above symptoms.
3. Zygomatic bone fracture will cause trauma and infection in the interstitial tissues of the cheek, which will produce a large amount of inflammatory substances that will lead to the normal conduction of the trigeminal nerve to the sensation, and ultimately lead to the teeth of the upper jaw can not feel the external stimuli and numbness and no sensation of symptoms.
Zygomatic fracture of the upper row of teeth without feeling is recommended to consult a doctor for a clear diagnosis and symptomatic treatment, in order to avoid delaying the condition.
