Incidence and Risk Factors of Delayed @entity3541 After XXXX Resection.

@entity1 @entity230 @entity5513 @entity5 @entity425 @entity2103 @entity3541
BACKGROUND: Preservation of @entity2103 following @entity5513 surgery is a high priority. Even those @entity1 with normal to near-normal function in the early postoperative period remain at risk for @entity3541 ( @entity3541 ). OBJECTIVE: To evaluate the incidence and prognosis of @entity3541 and to identify risk factors for its occurrence. METHODS: A retrospective cohort study of 489 @entity1 who underwent @entity5513 resection at our institution between 2000 and 2014. Delayed @entity3541 was defined as deterioration in facial function of at least 2 House-Brackmann (HB) grades between postoperative days 5 to 30. Only @entity1 with a HB grade of I to III by postoperative day 5 were eligible for study inclusion. RESULTS: One hundred twenty-one @entity1 with HB grade IV to VI @entity425 at postoperative day 5 were excluded from analysis. Of the remaining 368, 60 (16%) @entity1 developed @entity3541 (mean 12 days postoperatively, range: 5-25 days). All @entity1 recovered function to HB grade I to II by a mean of 33 days (range: 7-86 days). @entity1 that developed @entity3541 had higher rates of gross total resections (83% vs 71%, P = .05) and retrosigmoid approaches (72% vs 52%, P < .01). There was no difference in recovery time between @entity1 who received treatment with @entity230 , @entity230 with antivirals, or no treatment at all (P = .530). CONCLUSION: @entity1 with a gross total @entity5 resection or undergoing a retrosigmoid approach may be at higher risk of @entity3541 . The prognosis is favorable, with @entity1 likely recovering to normal or near-normal facial function within 1 month of onset.
