Long-term subjective and objective outcome after primary repair of traumatic facial nerve injuries

Although traumatic facial nerve paralysis is a severe handicap, there are no follow-up studies evaluating outcome after primary repair of traumatic facial nerve injuries. From May 1988 to August 2005, 27 patients (mean age, 27 years) were operated for traumatic facial nerve lesions (mean number of affected branches, 2.2). End-to-end facial nerve repair was always performed. All patients were invited to our outpatient clinic for standardized questionnaires (Facial Disability Index, Short Form-36 Health Survey), physical examination (Sunnybrook Facial Grading System), and clinical photographs. Sixteen patients participated in the follow-up study (mean, 9.2 years). Mean Facial Disability Index Physical and Social scores were 86 and 81, respectively, indicating good subjective facial functioning. The mean Sunnybrook Facial Grading System score was 74 indicating adequate facial functioning. Mean physical and mental health scores (Short Form-36 Health Survey) were comparable with normative data. Primary end-to-end repair of traumatic facial nerve injuries results in good long-term objective and subjective functional and emotional outcome.
