Long-term outcomes of Gillies and McLaughlin's dynamic muscle support in irreversible facial paralysis: A retrospective single-centre study with 25-year follow-up

The aim of this study was to evaluate the long-term outcomes of Gillies and McLaughlin's dynamic muscle support with regard to functional outcomes and assess possible effects of comorbidities on both functional outcomes and reoperation and complication rates. A retrospective single-centre study was conducted in all patients (n = 154) who underwent surgical correction of irreversible facial paralysis from 1994 to 2018. Patients with either Gillies procedure or McLaughlin's dynamic muscle support or a combination of these techniques were included in the analysis. Data on reoperations, comorbidities, complications, functional outcomes and patient satisfaction were analysed. Sixty-nine patients had Gillies and McLaughlin combination, 12 patients had Gillies and 33 patients had McLaughlin procedure alone. Patient satisfaction was generally high (>80%) and highest when McLaughlin procedure alone was performed and in patients without comorbidities. Reoperations were performed in 80 patients (70%; mean 2.2 +/- 1.7) and complications affected 16 patients (14%). Smile ability and movement control of the corner of the mouth were achieved in >85% of patients operated, whereas complete eyelid closure and facial symmetry at rest were attained in only 46%-68% of patients. Patients with no underlying medical conditions were able to smile more often, had motor control of the corner of the mouth, better facial symmetry at rest and fewer complications. Although newer surgical techniques are offered in many centres, this study shows that conventional facial reanimation of irreversible facial paralysis with Gillies or McLaughlin's dynamic muscle support or a combination of both produces yield good results and, therefore, continues to be a viable treatment option for many patients.
