Background:
The prognostic factors of facial paralysis complicated by middle ear cholesteatoma (MEC) are largely unknown due to limited reports and smaller sample size.
Objectives:
This study aimed to analyze prognostic factors of postoperative outcomes of facial paralysis complicated by MEC.
Material And Methods:
Clinical data of 48 patients (48 ears) with facial paralysis complicated by MEC were retrospectively reviewed and analyzed. The outcomes of facial paralysis were compared between different groups.
Results:
All the eight cases (100%) with intact fallopian canal had complete recovery of facial paralysis after surgery, while only 52.5% cases (21/40 cases) with fallopian canal damage achieved good recovery, with significant difference (p < .05). For subgroup analysis of the 40 cases with damaged fallopian canal, the good recovery rate of facial paralysis in shorter duration group (≤2 months) was higher compared to longer duration group (>2 months) (81.0% versus 21.1%; p < .05). Moreover, the good recovery rate of facial paralysis in moderate facial paralysis group (grade II-IV) was higher compared to severe facial paralysis group (grade V-VI) (82.4% versus 30.4%; p < .05).
Conclusions And Significance:
The outcomes of facial paralysis complicated by MEC were associated with fallopian canal integrity, duration and severity of facial paralysis.
