The impact of XXXX on @entity2103 after parotidectomy.

OBJECTIVES/HYPOTHESIS: Studies of immediate postoperative @entity2103 following parotidectomy focus on benign disease. The purpose of the study was to compare @entity2103 with regard to benign or @entity5 in @entity1 undergoing superficial parotidectomy. STUDY DESIGN: Retrospective cohort study of consecutive @entity1 undergoing parotidectomy between 1995 to 2002. METHODS: House-Brackmann (HB) grade was recorded or assigned at the first postoperative visit. For @entity1 with HB grade of III or greater, final resolution of @entity2103 was recorded. A chi2 analysis for independence was conducted between @entity1 with HB grade of II or less and those with HB grade of III or greater and final pathological finding (benign vs. @entity5 ). Mean and median times to resolution were determined for @entity1 with HB grade of III or greater. Times to resolution for benign and @entity5 for those with HB grade of III or greater were compared (Kaplan-Meier method). RESULTS: Sixty-seven @entity1 with benign disease and 52 with @entity5 were included. Ninety-four percent of @entity1 with benign disease had HB grade of II or less at first postoperative visit (mean period, 11.6 d) compared with 76.9% of @entity1 with @entity5 (mean period, 12.4 d). A chi2 analysis found this difference significant (chi2 = 7.36, P =.0067). Time to resolution for HB grade of III or greater was 253.8 days (+/-168.2 d) with median time of 229.5 days for benign disease and 182.4 days (+/-134.6 d) with median time of 138 days for @entity5 . Kaplan-Meier comparison found no significant differences in time to final resolution (P =.83). Three @entity1 in the group with @entity5 had @entity409 (one @entity1 for >2 y). CONCLUSIONS: @entity1 with benign disease have a greater chance of having HB grade of II or less immediately following surgery; however, whether the disease is benign or malignant, long-term final @entity2103 is the same.
