Modified Technique for Rehabilitation of Facial Paralysis Using Autogenous Fascia Lata Grafts

PurposeIn this retrospective study we used a modified surgical technique for midface reanimation in patients with facial nerve paralysis. Facial atonicity can cause functional impairment regarding speech articulation, oral competence, breathing, and eyelid closure. Furthermore, esthetic and psychological aspects play an important role in patients' emotional interaction and social integration. The chosen rehabilitative technique should offer support against prolapse of facial structures and remedy of functional disabilities and, thereby, prevention of social stigmatization due to disease-related changes in appearance.Materials and MethodsBetween 2005 and 2013, fascia lata grafts were used as static support in 15 cases of unilateral facial paralysis. Two fascia lata grafts were subcutaneously inserted in the upper and lower lips crossing the midline and sutured at 4 points, including the unaffected part of the orbicularis oris muscle and modiolus. The slings were suspended against the zygomatic arch with an osteosynthesis plate.ResultsThe patients perceived surgery results as considerably improving their appearance, speech, and alimentation. In 93.3% of cases, no postoperative complications occurred. The follow-up results (8 months to 8 years) remained stable.ConclusionsThis retrospective study showed the advantages of static facial reanimation in appropriate cases. The bony fixated support of the fascial slings allows an immediate improvement of facial symmetry. Additional attachment points including the unaffected part of the orbicularis oris muscle and the use of 2 independent fascia lata slings allow a more accurate adjustment of suspension forces and an incomplete dynamic reanimation of the mouth corner. With respect to its simplicity and minimal invasiveness, this surgical procedure is associated with low morbidity and rapid improvement of the patient's esthetic appearance.
