Identification of ear fracture and work-related injury Evaluation of several grades of disability if it is work-related injury. According to GB/T 5. 10.2 Ten-level clause series: 12), there is no dysfunction or mild dysfunction after fracture healing in all parts of the body. It may constitute a level 10 disability. Grade 10 disability is one of the disability grades. According to the Industrial Injury Insurance Regulations of the State Council, the disability level is divided into one to ten levels. 10 disability refers to the partial limitation of daily activities, work and study, and social communication ability. The national standard for industrial injury identification, the standard * * * is 10. Those who meet the standards are all disabled in grades 1 to 4, most disabled in grades 5 to 6, and partially disabled in grades 7 to 10. C.4. 18 hearing impairment includes occupational noise deafness caused by long-term exposure to production noise, explosive deafness caused by pressure wave and shock wave, deafness caused by temporal bone fracture, inner ear concussion and cochlear nerve contusion caused by craniocerebral trauma, and hearing impairment caused by tympanic membrane perforation, tympanic membrane scar adhesion and external auditory canal atresia after middle and external ear injury. C.4. 19 The equipment and methods for hearing threshold determination must meet the national standards: GB/T734 1, GB4854 and GB/T7583. C.4.20 When pure tone audiometry is used to measure severe or extremely severe hearing impairment, auditory brainstem evoked potential (A.B.R) should be measured at the same time. C.4.2 1 auricle and external nose are completely or partially defective, which can be referred to "disfigurement of head and face" in plastic surgery. C.4.22 Otology balance dysfunction refers to vestibular dysfunction and balance dysfunction. Balance disorders caused by muscle, joint or other nerve injuries should be graded according to the degree of disability in related disciplines. C.4.23 Employees who suffer from functional visual impairment and deafness due to work-related injuries or occupation-related factors shall adopt corresponding special examination methods to make a definite diagnosis, and the disability assessment can only be conducted after determining the organic visual and hearing loss. Pseudodeafness should also be ruled out before disability assessment. Ear fracture will happen in practical work, so for the parties, if their rights and interests are damaged, the relevant parties can solve the problem reasonably, but the actual problem solving is difficult, so it needs to be standardized reasonably, so that their rights and interests will not lose the initiative.
