QS2: Outcomes Of Pediatric Dynamic Facial Reanimation After Two Decades

Abstract

Purpose: Pediatric facial paralysis has substantial functional consequences in a growing child including impaired quality of life. Microneurovascular facial reanimation is the gold standard for smile reconstruction; however, quantitative data are lacking regarding long-term outcomes, particularly beyond 10 years. The primary objective of this study was to evaluate the long-term surgical and patient-reported outcomes after dynamic reconstruction of unilateral facial paralysis in childhood.

Methods: A cross-sectional study was performed of patients in our institutional facial paralysis database (1978-2008) who underwent dynamic reconstruction of unilateral facial paralysis 20 or more years ago. All patients were treated as children with a staged cross face nerve graft and free functioning muscle transfer. Frontal facial photographs in repose and maximal smile prior to surgery, within 2 years post-surgery, and at long term follow-up were analyzed using the MEEI Face-Gram software for commissure excursion. Patient-reported outcomes were obtained using the FaCE Scale for subjective facial impairment and disability, as well as the FACE-Q Satisfaction with Outcome and FACE-Q Social Function scales. Results are reported as median [IQR] and non-parametric statistical analysis was performed with alpha of 0.05.

Results: Eleven patients were included with long term follow-up of 23.7 [5.6] years (6 females, 5 males; 5 congenital, 6 acquired; age at surgery 7.3 [6.3] years). For surgical quantitative measures, commissure excursion significantly improved from prior to surgery (-1.3 [7.4] mm) compared to follow up within 2 years post-surgery (7.0 [1.7] mm) (p<0.05) and from prior to surgery compared to long term follow-up (8.3 [4.9] mm) (p<0.001). There was no statistically significant difference in commissure excursion within 2 years post-surgery and at long term follow-up (p>0.05). For patient-reported outcomes, median FaCE Scale scores showed good function for social function (81/100), oral function (88/100), facial comfort (92/100), and overall score (75/100). On the FACE-Q Satisfaction with Outcome scale, 10/11 respondents somewhat agreed or definitely agreed with the statement, “I am pleased with the result.” On the FACE-Q Social Function scale, 10/11 respondents somewhat agreed or definitely agreed with the statements, “I make a good first impression” and “I feel confident when I participate in group situations.”

Conclusion: Dynamic reconstruction of unilateral facial paralysis in young children improves commissure excursion that is maintained at long-term follow up. As adults, these patients report a high level of satisfaction and social functioning with their smile reconstruction.
