[Clinical analysis of facial nerve palsy in middle ear and mastoid surgery in 23 cases].

OBJECTIVE

To investigate the cause, the prevention and the therapy of facial nerve palsy(FNP) which induced by the operation of middle ear and mastoid surgery.

METHOD

A series of 1032 cases undergone middle ear and mastoid surgery were reviewed between 1976 and 1991.

RESULT

23 cases FNP were identified. All were incomplete and peripheral. 13 cases of them were performed decompression of facial nerve. 6 cases were cure, 4 cases on the mend and 3 cases no effect after operation. 10 cases were treated by conservation, 5 cases were cure, 3 cases on the mend and 2 cases no effect.

CONCLUSION

If the facial paralysis occurs during the operation, which means that facial nerve is damaged, except hard-stuff reason. Exploration should be done at once. If facial paralysis occurs later, conservative therapy should be selected at first. If facial paralysis is still not on the mend 1 month of postoperation, one should be done exploration of facial nerve.
