Abstract

Background

Management of facial paralysis in older patients is controversial. The purpose of this study is to evaluate the impact of increasing age on functioning free muscle transplantation (FFMT).

Patients and Methods

Twenty‐nine facial paralysis patients over 50 years old received FFMT. A separate group of patients aged 41–50 years old were included as control. Outcome assessments included use of the SMILE evaluation system for excursion, a cortical adaptation scoring system for brain plasticity, and a subjective satisfaction assessment score. Meta‐analysis of literature over the past 50 years was also performed to examine the impact of older age.

Results

The mean change in excursion movement was 13.39 ± 5.49 mm. Weakest excursion was found in the oldest age group (11.74 ± 4.84 mm, p = .097), in concordance with the meta‐analysis. There was significant difference between the three different neurotizers (p = .036). Excursion and satisfaction score were significantly worse in the older cohort with the cross face‐nerve graft FFMT.

Conclusions

FFMT is a viable option in the elderly patient group but performs weaker in excursion. The choice of neurotizer is dependent on the patient's goals and the suitable age at which the benefits outweigh the risks.
