Trauma of mid-face region frequently involves nasal, zygomaticomaxillary complex and maxillary bones. It often results in many complications, and the most common one is nerve injury. The incidence is about 80%. However, the main sensory nerve that supporting mid-face region is trigeminal nerve, and the general complication followed by nerve injury of this area is hypoesthesia. It is relatively important to accept well clinical diagnosis and treatment of the trigeminal nerve hypoesthesia when it occurred after facial trauma. The purpose of this study was to share the experience of the treatment for trigeminal nerve hypoesthesia post mid-face trauma and keep following the symptoms after receiving treatments.
