作者报导颞骨岩部骨折248例,其中横形骨折26例,纵形骨折222例。69％的横形骨折及50％的纵形骨折可在X线象上显示骨折。初诊时如有耳聋及破坏性眼震(destruction nystagmus),应列入横形骨折;如无耳聋而只有耳内出血或鼓室出血,则应列入纵形骨折。外伤后听力损失如属传导聋,预后良好,80％的病例听力有自动恢复正常的可能,只有20％的病例,患耳和健耳维持着5—10dB的差距;但如果传导聋一开始就超过50dB,听力自动恢复至正常的可能性极小,应高度怀疑存在着 The authors report 248 cases of temporal bone rock fractures, including transverse fractures in 26 cases, 222 cases of longitudinal fractures. 69% of transverse fractures and 50% of longitudinal fractures can show fractures on X-ray images. Initial diagnosis of deafness and devastating nystagmus should be included in transverse fractures; longitudinal deformities should be included if there is no deafness and only intra-ear or tympanic hemorrhage. In the case of hearing loss after trauma, the prognosis is good, 80% of the cases can be automatically recovered to normal hearing, only 20% of cases, ear and healthy ears to maintain a 5-10dB gap; but if the conduction of hearing loss More than 50dB, hearing the possibility of automatic return to normal is extremely small, should be highly doubtful existence
