Background: Facial synkinesis can result in facial tightness, smile dysfunction, and eyelid aperture narrowing due to overactive and uncoordinated muscle activity. We hypothesized that the outcome of a selective neurectomy could rely on the patient's chief complaints. Methods: We retrospectively reviewed 122 patients who underwent selective neurectomy at our hospital. Preoperatively, the patients were asked nine questionnaires to identify their two major chief complaints (treatment priorities). Postoperatively, facial tightness, limited mouth movement, and eyelid aperture narrowing were measured. Results: The most common chief complaints in our series were facial tightness (n=38), eyelid narrowing (n=32), and limited mouth movement (n=28); the second most common chief complaints (second priority) were limited mouth movement (n=47), facial tightness (n=21), and eyelid narrowing (n=20). The mean score for facial tightness significantly improved from 4.3 to 1.1 in the first priority group. Among the 28 patients whose corners of the mouth constituted the top priority of surgical correction, the vertical inclination on the affected side significantly improved from 74.1 ± 7.6° to 55.5 ± 6.0°, and the horizontal angles were changed from 4.2 ± 2.7° to 2.0 ± 1.3° after selective neurectomy without statistically significant. Among the 32 patients for whom eyelid narrowing constituted the top priority, the mean eyelid narrowing score improved from 4.5 ± 1.1 to 1.5 ± 1.2. Conclusions: Selective neurectomy can provide a significantly satisfactory outcome regarding facial tightness and eyelid aperture narrowing. The vertical inclination of the mouth corner can be significantly improved, while the improvement of horizontal angles can be suboptimal.
