[Evaluation of diagnostic sensitivity of electroneurography for XXXX ].

@entity1 @entity2652
OBJECTIVE: To evaluate diagnostic sensitivity of electroneurography (ENoG) for @entity2652 . METHODS: The data of 24 @entity1 suffering from @entity2652 on one side, having non-emergency operation, and having preoperative records of ENoG were collected. Among the @entity1 , 18 were @entity1 and 6 were @entity1 , aged from 3 to 55 years (median 28). The duration of injury before ENoG examination was from 1 to 56 days (mean 23.6 days) for them. The electroneurographic examination was carried out for facial nerves on both sides preoperatively. Percentages of evoked potential amplitude reduction on affected sides were calculated according to the value of normal side. The 90% reduction of amplitude was used as a cutting point. The @entity2652 was observed during operation. The sensitivity and false negative proportions of ENoG were analyzed. RESULTS: Among the 24 @entity1 with @entity2652 , 22 had ENoG amplitude reduction over 90%, and 2 having this reduction less than 90%. The sensitivity and false negative proportions of ENoG in @entity1 with @entity2652 were 91.7% and 8.3% respectively. CONCLUSION: The preoperative ENoG examination is high sensitivity for @entity2652 . The @entity1 whose ENoG reduction over 90% should be advised to have a @entity2652 as soon as possible.
