目的 :研究慢性化脓性中耳炎 (CSOM )引起全聋或极度聋的相关危险因素。方法 :回顾性分析我院1 9932 0 0 0年手术的伴极度聋或全聋的CSOM患者 6 0例 6 2耳 (全聋组 )的临床资料 ,并与同期不伴耳聋的CSOM患者 6 2耳 (对照组 )进行比较。结果 :全聋或极度聋相关的危险因素包括流脓血、听骨链破坏及镫骨足板或板上结构消失 ,两组比较具有极显著性意义 (P <0 .0 1 ) ;与迷路瘘管有无亦相关 (P <0 .0 5 )。而与病程、并发面瘫及再次中耳乳突手术等因素无明显相关。结论 :全聋或极度聋的发生与流脓血、胆脂瘤对听骨链侵蚀、镫骨板上结构或足板消失、迷路瘘管等相关。胆脂瘤和中耳感染如不及时控制可能导致全聋或极度聋
Objective: To investigate the related risk factors of total deafness or deafness in chronic suppurative otitis media (CSOM). Methods: The clinical data of 60 cases of CSOM patients with deafness or total deafness operating in our hospital from January 19 to January 30, 2002 were retrospectively analyzed. The clinical data of 62 patients with CSOM (total deafness) were compared with those of CSOM patients without deafness Ear (control group) for comparison. Results: The risk factors of total deafness or deafness included abscess blood flow, destruction of ossicular chain and the disappearance of stapes foot plate or plate structure. The two groups were highly significant (P <0.01) Fistula also related (P <0. 05). And with the course of the disease, concurrent facial paralysis and again middle ear mastoid surgery and other factors was not significantly correlated. CONCLUSION: The incidence of total deafness or deafness is related to the abscess of blood flow, cholesteatoma to ossicular chain erosion, the disappearance of the supraspinatus or foot plate, and the fistula of the obstruction. Cholesteatoma and middle ear infections, if left untreated, may result in total deafness or extreme deafness
