Xiaohua's injury has the conditions of serious disfigurement. Is it simply classified as level 3? Don't! According to the case, Xiaohua was 28 years old when he was injured. According to the appraisal standard, female employees under 40 years old have facial disfigurement, including single nose defect, maxillofacial defect (excluding auricle defect) and facial paralysis, and are promoted to 1 according to the disability grade. Therefore, Xiaohua's disability level should be changed from level 3 to 1 to level 2.
