Oculofacial contour asymmetries: Management of combined treatment with hyalurostructure and botulinum toxin injections

Abstract

Purpose. To assess the long-term results of the treatment of oculofacial asymmetries using a combined injection schedule for injections of hyaluronic acid, with a specific micro cannula and botulinum toxin. Method. A retrospective study was conducted from January 2009 to January 2010. Patients were treated in the Alcazar Eye Clinic and Oculoplastic Department in Princess Grace Hospital, Monaco. We selected patients complaining of asymmetrical periorbital features who received treatment with hyalurostructure and botulinum toxin injection in one or more sessions. Nine patients were selected and presented with the following symptoms: asymmetry of eyebrow position (2 patients), superior orbital hollow (2 patients), tear trough (2 patients) and orbital volume (ocular prosthesis) (3 patients). The objective was to evaluate the efficiency of combined treatment in one or more sessions on these oculofacial asymmetries. Hyaluronic acid injections were done using hyalurostructure. Hyaluronic acid gel (Restylane Lidocaine) was used with a 25 gauge reinforced micro-cannula (pix'l +, Thiebaud). This was combined with injections of botulinum toxin (azzalure*) to areas of muscular hyperaction. Follow-up was done at 1 year by clinical examination, photography and patient satisfaction. Complications of this combined treatment have been identified. Results. At 1-year follow-up, 88% of patients were satisfied or very satisfied with their results. There were no more complications secondary to both treatments in the same session. It was not noticed more hematomas and bruises than in classical injection method. The action of toxin is constant over time despite the association of hyaluronic acid injections. Conclusion. Combined treatments with toxin and hyaluronic acid in oculofacial asymmetries are efficient and can be proposed in the same session. These treatments must be repeated to maintain and optimize muscle contraction and volume loss. Use of hyalurostructure and botulinum toxin treatment in the same session is effective and safe.
