乳突根治或鼓室成形术后远期发生的面瘫在选择疗法时可有困难,尤其是在术腔无明显炎征者。由发病机制看,最常因面神经管内神经干受压而致神经阻断,其直接原因可为炎症水肿,亦可由于骨壁破坏后来自外部的压迫致成。神经功能的恢复取决于治疗方法和及时与否。慢性化脓性中耳炎并发面瘫时应紧急手术,目前已无争议;而乳突根治或鼓室成形术后数月或数年才发生的面瘫的治疗方针尚无定论。作者报告术后远期面瘫7例,探讨其直接病因和神经机能恢复与治疗措施间的依从关系。患者行乳突根治或鼓室成形术后已2月～40年;面瘫至就诊时间由4天～5年。全部均行手术查明 Facial paralysis due to radical mastoidectomy or tympanoplasty may be difficult at the time of selection therapy, especially if there is no obvious inflammation in the surgical cavity. From the perspective of the pathogenesis, most often due to neural tube nerve pressure within the facial nerve tube caused by nerve block, the direct cause of inflammation and edema, but also due to the destruction of the external wall after the destruction of the wall. The recovery of neurological function depends on the treatment and in time or not. Chronic suppurative otitis media complicated by facial paralysis should be emergency surgery, has been no controversy; and mastoid radical or tympanoplasty months or years after the occurrence of facial paralysis treatment guidelines are not conclusive. The authors report 7 cases of postoperative long-term facial paralysis to explore the direct etiology and neurological recovery and treatment of compliance between the measures. Patients with mastoid or tympanoplasty after 2 months to 40 years; facial paralysis to treatment time from 4 days to 5 years. All were identified by surgery
