[Peripheral facial paralysis in temporal bone trauma and cholesteatoma otitis media].

OBJECTIVE

To investigate into the surgical approaches and clinical curative effect of peripheral facial nerve paralysis in different causes and injury location.

METHOD: Thirty-two cases of peripheral facial paralysis were treated with selective facial nerve decompression via different surgical approaches. After 0.5 year to 2 years follow up, the recovered functions of facial nerve were judged by House and Brackmann grading system.

RESULT: In all patients, 17 cases of peripheral facial paralysis caused by trauma were underwent facial nerve decompression in two weeks, 11 cases reached degree I (84.6%) according to House-Brackmann (H-B) facial nerve function scores, 3 cases were treated in the third week, 2 cases reached degree II and other 1 cases reached degree III. One patient was treated after 8 weeks and facial nerve function scores only reached degree VI. Thirteen cases of otomastoiditis in middle ear were underwent facial nerve decompression in one week, postoperative House-Brackmann grade was I in 8 cases, II in 2, and III in 4.

CONCLUSION

Majority of patients with peripheral facial paralysis were treated with facial nerve decompression have better clinical curative effect by suitable operation and juncture due to trauma or cholesteatoma otitis media, but operation for traumatic peripheral facial paralysis should be undertaken in two weeks.
